@majordennisbloodnok Talking of Robins.. This is more a case of a ‘Round Robin’; I had an email from MyEnergy last week that provided a link to arrange the return of the original Eddi (not that he had even been removed at that time). The email was supposed to provide a link I could use to arrange for Royal Mail to collect the parcel, stick a printed return label on it and Robert is your parent’s brother! You have probably guessed, the link didn’t take me to the right place; so I replied to that email and explained that the link didn’t provide what they described. The email was bounced back with a ‘Rejected’ message. This explained that the case number was now invalid and could not be delivered! Grrr. Toodles.

Purely from a business process perspective, this is bad implementation of flawed logic.
A lot of companies look at automation and think "Ah, now we can replace the humans doing that bit of our workflow with something automated". What they should be thinking is, "Here's this new piece of technology that can automate certain things. In the light of that, how do we want our workflow to operate?"
Yes, adding chatbots to a site sounds great and is made very easy by those developers. But how many times do we find it does not fit your screen, it does not "remember" your name even if you are logged onto the ticketing system, etc? Unless there´s some AI, you are likely to find it asks you to send a message and of course it "forgets" to send you a copy of your query..

Ok, here follows an update on the current situation with MyEnergi and their stubborn resistance to realise that their AI Chatbot based support services leave a great deal to be desired. I have again endeavoured to anonymise myself in the protracted email correspondence and I apologise as someone within MyEnergi saw fit to re-arrange some of the order of the correspondence. I’m sorry it is so long but I would be grateful if any readers can find the fortitude and perhaps a very long drink to read at least some of this sorry tale. The latest entries are at the top and they start (at the bottom) where I left off last time; they bring matters up to Feb. 13th. pm.
There are many emails on the subject of having to reset the Eddi to work with the CT clamps (which MyEnergi seem to think is my responsibility as apparently, we have altered the settings! (This is news to myself and Cinergi!) It would seem that it is standard practice to send a third party ‘fitter’ who knows nothing about wiring up an Eddi and that it is our fault by confusing him by arranging a temporary bypass so we could have hot water during this extended period. The ‘fitter’ does not have the information on how to wire up an Eddi for use with a Sunamp Thermino it would seem. It is of course, all my fault because I wanted to have a supply of hot water - how inconsiderate of me!
The second ‘tranch’ of the email trail follows:
MyEnergy emails Pt.2
Hello Chris.,
I find it interesting that you would send a third party to carry out the changeover from the failed to the replacement Eddi diverter. I gather that this third party is instructed to swap the units but it would appear that they do not necessarily have the knowledge that an electrician might be expected to posses when carrying out electrical wiring in a domestic dwelling without supervision.
At the time that the Cinergi electrician came and corrected the incorrect wiring carried out by your third party person (Matt) so that we might have hot water again, he remarked that the state of the wiring was ‘Horrendous’; I have now received that electrician’s comments:
I am told…
“He said that the sun amp was wired in a way that meant it would only work if the Eddi was to produce surplus solar, which in turn meant that it could not function to heat the hot water. The relay card in the Eddi that was to feed the towel rail was not connected to anything. It has the live supply to the Eddi in the 'C' terminal and the towel rail was wired into H2, which had no priority, meaning it would never have worked in any case.
The relay should have had a permanent supply into 'C' and the towel rail supply into 'no2'
The supply to the Sunamp needed to be permanently fed with the 'H1' of the Eddi feeding into the Sunamp override (meaning it turns on with excess solar)”
I am very disappointed that you feel that the need to call in my own electrician to rectify the incorrect wiring carried out by your third party was not required and that you would have willingly put this right yourselves. To me, history suggests that the already extended interval without hot water would have been further extended and this was not acceptable for the reasons I have set out previously.
I thought that I was purchasing a British product from a well respected manufacturer who would also supply exemplary support should the need arise; it would appear that I was mistaken in this belief.
Regards,
Me

Your support ticket 759856 has been updated. To add additional comments, reply to this email. Chris Davis (myenergi) 12 Feb 2026, 13:35 GMT
Hi xxxx,
Good afternoon. We have nothing further to add. We asked a third-party installer to swap and set up a suspected Eddi unit, which they did. We were not aware that the wiring had been changed to the Sunamp to provide hot water, and we did not make any changes ourselves. When the third-party installer returned, they simply carried out the instructions they were given it is not their responsibility to rewire equipment that does not belong to them or to us.
Darren did, however, offer to send someone free of charge to carry out this work, which is going above and beyond. You chose for Cinergi to handle the remedial work instead. While that is, of course, your choice, it is not something we will be covering financially.
In situations like this, the standard practice is for the installer who changed the wiring to leave a note with the Eddi/Sunamp explaining what was done as a temporary fix and what will need adjusting when the unit is swapped. This was not done. The third-party installer would not have known any difference, as the Eddi would have simply switched on as normal with no indication that rewiring was required.
For context, and without being quoted on this, bypassing power to a Thermino Sunamp is relatively simple it typically involves bridging the connection inside the Eddi, bypassing the Eddi completely without touching the wiring on the Sunamp itself. If this was done, then swapping the Eddi unit should be all that is required.
Best regards,

Best regards, Me 4 Feb 2026, 13:24 GMT Hello Chris, Further to my reply earlier, I would add that my first attempt at contacting MyEnergi over this whole sorry matter was on Monday 5th. January but that and all other attempts at communication until Thursday 8th. January do not show in your email trail despite the AI statements that the matter was being handed on to a human. Over subsequent days and weeks, despite pointing out that my wife and I are elderly, disabled and in need of hot water for medical reasons, your support system appears to respond at a snail’s pace. May I suggest that you review that early email content and reconsider your stance on this matter please? Regards, Me I heat our home with cold draughts and cook food with magnets! Me 4 Feb 2026, 12:00 GMT Hello Chris. I would like to point out that I attempted to contact MyEnergy at the very start and your system STRONGLY RECOMMENDS that contact should be established via the AI chatbot for the quickest resolution. The nearest I came to speaking to a human was on (I think) the third attempt when the chatbot stated I would be contacted by a human - this did not happen. I called in Cinergi as my installer and your approved supplier; the electrician established the fault was indeed with the Eddi. He effected a bypass so that we would still have hot water. When I eventually established contact with a human several days later after many attempts to do so, I was informed a replacement unit would be sent out and this happened several days later. The replacement unit arrived on the following Monday and then I awaited advice of when the fitter would be coming. I then heard that the fitter would come on that Wednesday. He failed to arrive. He then promised to come on the Thursday and failed to do so. He finally came on the Friday. I informed him that the Cinergi electrician had made a temporary link so that we might continue to have hot water available. The Cinergi electrician did not touch or reconfigure the Harvi’s or CT clamps in any way but I understand all the settings would have been lost when the Eddi failed. The fitter (Matt) informed me he would rewire the Eddi but he did not mention that he would not rewire to connect the Sunamp Thermino system. Matt obviously did not test the system as after he left leaving me to try and set up a schedule using the MyEnergy app, I found that I could not heat the water - even by switching the Eddie to ‘Byoass’. This as it turned out wass because the wiring had not been connected as required for a Sunamp. Incidentally, much time and effort was expended over this wiring and Cinergi even sent the Support team the details for the correct connections for this purpose. I would also point out that the reason the Cinergi electrician made a temporary connection for me so as to provide hot water was that the bypass switch on the faulty Eddi did not work. The switch will not engage in the bypass position. Had the Cinergi electrician not made a temporary connection, we would have been without hot water throughout this whole event. As mentioned. I endeavoured to contact your company and was frustrated by the AI chatbot failing to connect me with a person. All attempts were subject to extended delays and even at the time that Darren might arrange a further visit from a fitter, no timescale was mentioned at all and we were still without hot water! I have had numerous emails and have replied to Darren making changes to the Eddi settings as these were not made whilst Matt was here as he informed me he had nothing to do with the settings. Regards, Me I heat our home with cold draughts and cook food with magnets! Chris Davis (myenergi) 4 Feb 2026, 11:27 GMT Hi there Chris here, the Customer Experiance Manager.
I’m very sorry to hear about the recent failure of your Eddi. When issues like this arise, we would always recommend contacting us in the first instance so that we can assess the fault and arrange an installer where required.
I understand that you chose to arrange your own installer, which of course is your decision, but any costs incurred in doing so would be payable by yourself. From what we can see, the person who attended confirmed the Eddi was faulty and rewired the Sunamp to provide you with hot water, which is completely understandable everyone needs hot water.
The issue arose because when we subsequently sent an engineer to replace the Eddi, we were not aware that the wiring configuration had been altered. Our instruction to the third-party installer was to carry out a straight swap and setup of the Eddi, not to reconfigure or modify any existing wiring. As a result, this part of the work is not something we are liable for, as it was not changed by us.
As Darren mentioned previously, we were more than happy to send an installer to reconfigure the cabling as a goodwill gesture, in that you did not take Darren up on this offer is entirely your choice but again means payment to your chosen installer would be payable by you.
In addition, regarding the positioning and setup of the CT clamps, I have spoken with Darren and he is going to help ensure these are checked and corrected if required. As a further goodwill gesture, I am also happy to send an installer to rectify this aspect if needed.
Please note that we are not liable for incorrect CT clamp setup, so any work carried out in this regard would be purely as a goodwill gesture on our part.
Please let me know how you’d like to proceed.
Chris Davis Me 4 Feb 2026, 11:19 GMT New readings. Me I heat our home with cold draughts and cook food with magnets! Me 4 Feb 2026, 11:09 GMT done. Me I heat our home with cold draughts and cook food with magnets! Darren (myenergi) 4 Feb 2026, 11:04 GMT Hi xxxx, coud you try this please. Could you go into the eddi menu again, device settings, installer settings,(password0000), linked devices, devices, harvi 1443293, and set ct1 and 2 to ac battery please. It looks like you might be producing 900w of solar right now, and the batteries arent doing anything. Darren Me 4 Feb 2026, 10:39 GMT Darren, The solar harvest now exceeding the consumption, here are 3 mor screen grabs for you. Regards, Me I heat our home with cold draughts and cook food with magnets! Me 4 Feb 2026, 10:32 GMT Hello Darren, The battery will at present, supply any power above that which the solar panels are providing and of course changes dynamically. I have just sent some more screen grabs showing Enphase app readings too. Matt did go to the 2nd Harvi and I think I heard him removing some plastic trunking covers to ascertain which CT clamp went where. There are two black lead CT clamps and one grey one. The grey lead enters the middle access hole on the Harvi. The battery will continue to work with solar power as available until 13:00 when the tesla app will conect to grid to top up the charge again. Regards, Me I heat our home with cold draughts and cook food with magnets! Me 4 Feb 2026, 10:26 GMT Hello Darren, Voracity Check: The attached 3 screenshots were all taken within seconds of each-other and suggest that any erronous reading is with the Eddi; both Tesla and Enphase apps are in agreement on solar production. Regards, Me. I heat our home with cold draughts and cook food with magnets! Darren (myenergi) 4 Feb 2026, 10:25 GMT Hi xxxx, The solar reading being off a little? Is it still off now? There are 3 ct's set to generation only, and im not 100% sure it is set correctly as i know you only have 2 solar systems. One of these ct's should be set to ac battery. Is your powerwall battery doing anything at the moment, or is it idle? Darren Me 4 Feb 2026, 09:43 GMT Hello Darren The attached were captured within seconds of eacother just minutes ago as we have some sun this morning! Regards, Me I heat our home with cold draughts and cook food with magnets! Darren (myenergi) 3 Feb 2026, 16:11 GMT Hi xxxx, Thank you for clarifying. I do believe you that the eddi bypass switch didnt work correctly. It is an odd fault to have on an eddi, but when we get it back here, it will get looked at. Darren Me 3 Feb 2026, 15:33 GMT Darren, I attempted to send you this message along with a short video of me attempting to operate the bypass switch but it was rejected by your system. Thr fact remains, the Eddi would not allow bypass mode to be used. “ Darren, The failed Eddi was picked up by Royal Mail today; I’m attaching a short video of me attempting to use the bypass switch which will not engage for me. I have no idea whether it ever worked as I don’t believe I have ever had need to use it anyway. Pity it didn’t work when it was most needed. Regards, Me I heat our home with cold draughts and cook food with magnets! Me 3 Feb 2026, 15:09 GMT Darren, This is how the display looked one day last year and may give you some ideas. Me I heat our home with cold draughts and cook food with magnets! Me 3 Feb 2026, 15:00 GMT Yes, there was an icon rather like a battery in appearance; it was in a position of about 7. O clock on the display. and it did indicate flow to or from. Me I heat our home with cold draughts and cook food with magnets! Darren (myenergi) 3 Feb 2026, 14:53 GMT Hi xxxx, That symbol that was on the myenergi app earlier wasnt a battery icon, it was a storage icon, which is for a 3rd party device like your eddi. Did you have one on there before the eddi was swapped out? Darren Me 3 Feb 2026, 14:40 GMT We seem to have lost any battery sensing on the MyEnergy app - it was on the display before! Regards, Me. I heat our home with cold draughts and cook food with magnets! Me 3 Feb 2026, 14:30 GMT The Powerwalls ease off on the final few percent of charging and I’m attaching a more recent screenshot now. I heat our home with cold draughts and cook food with magnets! Darren (myenergi) 3 Feb 2026, 14:17 GMT Hi xxxx, Im only seeing 1.3kw coming from the grid. Has the import dropped? Darren Me 3 Feb 2026, 14:11 GMT Right, that Harvi has been reset to grid and the other Harvi now has all thre CT’s showing Generation Only. (I did not alter the second or third ones, they were already set like that). The grid is charging the battery at present. I use Octopus Cosy and 13:00 - 16:00 is the cheap rate time. Regards, Me. I heat our home with cold draughts and cook food with magnets! Darren (myenergi) 3 Feb 2026, 13:57 GMT Hi xxxx, Apologies, could you set that ct back to grid please in harvi 1047349, and in the other harvi , 1443293, set ct 1 to generation only. Are the powerwalls discharging to the grid at the moment? Darren Me 3 Feb 2026, 13:37 GMT Hello Darren, I have changed the Harvi (the top one on the list) so that CT1 is set to Generation Only. I am attaching screenshots taken within seconds of eacother of the Tesla and MyEnergi apps. It may not be relevant but, when Matt wired up the warranty replacement Eddi, he asked me if the two Harvi’s were on the same channel; as I didn’t know I had to leave him to work that out for himself. Regards, Me I heat our home with cold draughts and cook food with magnets! Darren (myenergi) 3 Feb 2026, 12:15 GMT Hi xxxx, What is the battery app and myenergi showing as solar production. Are they reading the same? Could you go to your eddi please and go into the menu, device settings, installer settings (password0000), linked devices, devices, harvi, and set ct1 to generation only as well please. Darren Me 2 Feb 2026, 17:12 GMT Darren, I will endeavour to do so, the greatest variable is ‘If the sun shines at all’ under current weather conditions! Regards, Me. I heat our home with cold draughts and cook food with magnets! Darren (myenergi) 2 Feb 2026, 17:02 GMT Hi xxxx, When you look at the tesla app, maybe tomorrow now, and you can see the solar production on there, does that show the same as the myenergi app? I can see there are 2 ct's set to generation only, so i can only assume these are both monitoring your individual solar productions, going to the inverter for each powerwall. Its hard to tell now as its dark, so tomorrow, when its sunny and both your panels are producing, if you can tell, could you send me a screenshot of the tesla app and the myenergi app please. Darren Me 2 Feb 2026, 15:51 GMT Darren, As I stated, they are Powerwall 2’s. Please clarify the second question. Regards, Me I heat our home with cold draughts and cook food with magnets! Darren (myenergi) 2 Feb 2026, 15:48 GMT Hi xxxx, The harvi is set a little oddly as i dont think it should have a storage ct set in it. Are they a powerwall 2 or 3 though? Does the solar production value show corerctly when they are just ion their normal modes? Darren Me 2 Feb 2026, 15:41 GMT Hello Darren, Firstly, the Powerwall battery, this is a 27 kWh system comprising 2 x Powerwall 2’s. The solar array has two ‘down pipes’ so to speak as we have 9 panels across 2 roofs on one feed into the Gateway and the other has 12 panels including 10 in the garden and these all feed into the second MTTP in the Gateway. The display used to tally fairly closely on the Tesla and MyEnergy apps. Regards, Me I heat our home with cold draughts and cook food with magnets! Darren (myenergi) 2 Feb 2026, 15:27 GMT Hi xxxx, Is it a powerwall 2 or 3? If its a powerwall 3 then these readings may be correct. I can see one of the ct's in the harvi is set to storage only. Im unsre what this is monitoring. Do you have 2 solar systems? Darren Me 2 Feb 2026, 14:34 GMT Hello Darren, I mentioned that the Eddi app was displaying nonsense values and I attach images to indicate this. In case you are unfamiliar with the Tesla app, here are the values which I find are very close to being realistic and over time, they appear to be moderately accurate; this indicates to me that the Harvi reports are erroneous at present. This is particularly so when the power appears to be being sent to the solar panels as in this screenshot. The two were taken within less than 2 seconds of each other. Tesla: Solar 0.3 kW. output, Domestic draw 1.4 kW. and Powerwall charging at 4.9 kW. (I realise that MyEnergi do not have the means to monitor the Powerwall setup but at least used to indicate the flow reasonably accurately) and the draw from Grid = 6.0 kW. I will leave you to see what the Eddi thinks it is! Regards, Me.
I heat our home with cold draughts and cook food with magnets! Darren (myenergi) 30 Jan 2026, 16:16 GMT Hi xxxx, Ill pass on to Viktoria. Darren Me 30 Jan 2026, 15:37 GMT Darren, This is what I sent to Viktoriia: Regards, Me I heat our home with cold draughts and cook food with magnets! Me 30 Jan 2026, 15:05 GMT Hello Darren, Ok, I did wonder, thank you for that. I have just tried to contact Viktoriia as the link she provided to arrange return of the faulty Eddi doesn’t provide the facility to arrange the return with RM picking up the parcel and bringing a label with them. The message has been rejected as the docket is now out of date it seems. I would like to have the parcel picked up on Monday as I will not be here tomorrow. Regards, Me I heat our home with cold draughts and cook food with magnets! Darren (myenergi) 30 Jan 2026, 14:38 GMT Hi xxxx, Once its up to temp, it will try to check it every 10 minutes or so to see if it still needs heating. Thew sunamp does have the effect of it getting to temp, then asking for power a little later. The specific settings that were originally put in for the sunamp have been superceeded by setting the icon to heat battery. Darren Me 30 Jan 2026, 14:02 GMT Now charging again @2.8 kW. Me I heat our home with cold draughts and cook food with magnets! Me 30 Jan 2026, 13:53 GMT Just looked at the Givenergi app on my phone again and it indicate ‘Max Temp Reached’, this suggests to me that the system is not checking the charge level (or temperature?) as it used to on the first Eddi. I will be packing up that one for return later today. Regards, Me I heat our home with cold draughts and cook food with magnets! Me 30 Jan 2026, 13:50 GMT Hello Darren, As directed, I have now set to Heat Batt. I notice that the programmed charge schedule still displays in the app but charging has stopped though the Sunamp needs far more charging as yet. The sunamp power LED is lit but neither of the ‘level of charge’ LED’s are glowing yet. Regarding the CT’s. One harvi is next to the consumer unit and I far as I know monitors grid. The other Harvi has a CT clamp on the solar panel output, and the other CT clamp goes to the Tesla Powerwall (x2). There is still no charge going to the Sunamp - does something need re=pragramming? Regards, Me I heat our home with cold draughts and cook food with magnets! Darren (myenergi) 30 Jan 2026, 13:03 GMT Hi xxxx, Great news. I have replicated the boost times to turn the towel rail on at 1915 for 3 hours for relay 2. Both harvis are set in the menu. One of the harvis has the grid ct connected, and the other has a storage ct and 2 generation ct's conencted. is this correct? Could you go inot the eddi menu please, device settings, display, icons, heater 1, press tick and use the up and down arrow to set it to heat batt. This is specific for the sunamp. Darren Me 30 Jan 2026, 11:44 GMT Darren, One more thing, the display is indicating ‘MAX TEMP REACHED’; this is after one hours charging at ~3 kW, as this is obviously not a full charge from ambient cold room temperature, I trust it will start charging properly on my scheduled times? I have a scheduled time of 13:00 - 16:00 today and this will confirm whether the MAX TEMP settings are set to recheck for ‘topping-up’ after a set interval. Regards, Me. I heat our home with cold draughts and cook food with magnets! Me 30 Jan 2026, 11:35 GMT Darren, This to let you know that Cinergi have now wired up the Eddi to the Sunamp Thermino and our DHW is heating up at long last. There are a number of settings to be adjusted please; I know little about how to set them but remember that a parameter needs to be set for Eddi to check with Sunamp to retry charging after a set interval as the heat dissipates into the PCM in the heat battery. I note also that there are no settings on the Harvi CT clamps yet, the lines for these are blank still. I wish to set up my towel rail heater which I understand is wired to Relay 2 but I cannot see any settings to programme for this; I would be grateful for instructions on the procedure for this please. I also note that the status display in the app does not reflect reality at times. Are the erroneous readings perhaps due to the CT clamps not been configured yet? I look forward to hearing from you please. Regards, Me I heat our home with cold draughts and cook food with magnets! Darren (myenergi) 29 Jan 2026, 16:45 GMT Hi xxxx, Ive said i will organise an installer to rectify the wiring. We cant pay any compensation im afraid. Darren Me 29 Jan 2026, 15:12 GMT Darren, I think I have made it abundantly clear that we have a need for hot water without delay; you wrote that you would only wire the Eddi as you seem to think it should have been wired. To my way of thinking, this was all you were prepared to do and so I have requested the services of Cinergi to return to the normal operating status we enjoyed previous to the failure. As for you stating it would not cost us anything - it has already cost me £210 and I appear to be without any hot water for the foreseeable future as you show no intentions of wiring the Sunamp as it was previously. We can sort out how you compensate us later please. Regards, Me I heat our home with cold draughts and cook food with magnets! Darren (myenergi) 29 Jan 2026, 14:54 GMT Hi xxxx, They will charge you, and i can send one of our guys out to change the wing over, so it wont cost you anything. Im hoping the bypass swicth works on this one? Darren Me 29 Jan 2026, 13:33 GMT Darren, After your previous correspondence in which you appear to have washed your hands of the whole wiring issue as we should have used the ‘Bypass’ switch rather than making temporary wiring to allow the Sunamp to charge, I have requested Cinergi to visit tomorrow to connect the warranty Eddi so that it will work. I would remind you that the ‘Bypass’ switch does not work and just returns to the off position as soon as it is released. I agree with you -this should not have cost us a penny. I did endeavour to establish contact with you via your AI chat bot but with very little success. Regards, Me I heat our home with cold draughts and cook food with magnets! Darren (myenergi) 29 Jan 2026, 13:07 GMT Hi xxxx, I will have to raise another ticket to get an engineer organised. Just for future reference, any issues, please come directly to us. We can diagnose issues over the phone and then organise everything thats needed. This shouldn't have cost you a penny. Darren Me 29 Jan 2026, 10:19 GMT Hello yet again Darren, The electrician has explained how the Sunamp was powered using connections within the Eddi, why is this not clear to you? To me that sounds like standard electrical practice! If you are not going to solve this problem out then I will take the matter further and your Directors will be hearing from us. A warranty repair that has cost me £210 just to determine tha fault lies within the Eddi and now you seem to think I should pay out to connect the warranty replacement. May I remind you the electrician had to use a temporary just to keep hot water supply going as the Eddi could not be set to Bypass? Regards, Me I heat our home with cold draughts and cook food with magnets! Darren (myenergi) 29 Jan 2026, 10:07 GMT Hi Rebecca, we wouldnt be able to cover this cost unfortunately as it wasnt us who made the changes. Our warranty installers will just replace the unit like for like and set up as the old one was. He was unaware of any rewiring that had happened. Darren Rebecca Churn 29 Jan 2026, 09:47 GMT Good morning Darren,
This can be arranged but it would be to a further cost to Mr xxxxxx. Will the bill be covered by Myenergy if we go back out to rectify this?
Kind regards Me 29 Jan 2026, 09:18 GMT My last email was for Darren and copied to you Rebecca, from the wording of Darren’s last note, would I be right in thinking that he is requesting that Cinergi might call and rectify this mess please? Regards, Me I heat our home with cold draughts and cook food with magnets! Me 29 Jan 2026, 09:10 GMT Hello Darren and Rebecca, The Cinergi electrician had no choice if we were to be provided with hot water until the time Matt came; the ‘Bypass’ switch would not engage, it just flipped back to the off position every time. Through the kindness of the Cinergi electrician, we had hot water on a temporary basis. Now, we have no hot water and have not had since Matt visited. May I remind you that (as I have mentioned in previous emails, my wife and I are disabled, elderly and have special medical needs - these are not being helped by a lack of hot water supply! I hope I will be hearing from you about a technician/engineer coming to rectify the problem today please? Regards, Me. I heat our home with cold draughts and cook food with magnets! Darren (myenergi) 29 Jan 2026, 08:53 GMT Hi Rebecca, Thank you for confirming. You are correct, this is where the eddi warranty installer may not have realised,as he will only be sent to replace the eddi like for like. So can you confirm what needs to be done. Does the brown permanent live need to go back into the fused spur to power the sunamp, as our warranty installer wont have done this. The faulty eddi could have been put into bypass mode when the issue occurred which would have kept it heating until the new eddi could be fitted. Would it be possible to return and rewire as it was originally please? Darren Darren (myenergi) 28 Jan 2026, 10:32 GMT Hi xxxx, Apologies, that message was for Rebecca, but the reaply is not visible by yourself. Darren Me 28 Jan 2026, 10:27 GMT May I suggest you ask Matt if he saw some Wago connectors on the lead please? Regards, Me I heat our home with cold draughts and cook food with magnets! Me 28 Jan 2026, 10:26 GMT The electrician mentioned to me that he was going to his van for some Wago connectors - could this be what you are asking? Me I heat our home with cold draughts and cook food with magnets! Darren (myenergi) 28 Jan 2026, 10:23 GMT Hi, Can I ask how it was heating the water without the eddi being connected, as the eddi supplies the power to the heaters. If it was connected to the mains, this may have needed to be removed when the eddi was installed? Darren Me 28 Jan 2026, 10:17 GMT Darren, As I have pointed out, I am not an electrician but… is it not possible that the cable from the Sunamp carries sufficient cores to provide two live connections - one from the supply into the Eddie and the other through the switched circuit? I can only see one lead between the Sunamp and Eddi. Regards, Me. I heat our home with cold draughts and cook food with magnets! Darren (myenergi) 27 Jan 2026, 16:16 GMT Hi Rebecca, I wonder if you could help me. I believe you have had an installer go back to one of our joint customers' sites, to deal with an eddi issue. You have diagnosed the eddi as being faulty and we have sent a new one out, to replace it., which ahs been done. Its not heating the customers water through his sunamp heat battery. I believe the installers wired it in a way so the custoemr, xxxxxxx could still have hot water while the eddi was being replaced. It looks like the sunamp isnt getting a 240v supply to it, and i wonderd if you could ask the installers where the permanent 240v supply for the sunamp comes from as the sunamp only seems to light up when the eddi is supplying 240v to it. Darren Me 27 Jan 2026, 16:13 GMT In case that didn’t show up, it is rebecca@cinergi.co.uk I heat our home with cold draughts and cook food with magnets! Me 27 Jan 2026, 16:05 GMT You will see that I have CC’s Rebecca Churn in already. Regards, Me I heat our home with cold draughts and cook food with magnets! Darren (myenergi) 27 Jan 2026, 16:02 GMT Hi xxxx, Can I have their email address please and ill cc them into this conversation Darren Me 27 Jan 2026, 15:59 GMT Hello Darren, I am not an electrician and employed Cinergi (as the agent for both MyEnergi products and Sunamp). As I have already suggested, Cinergi electricians are the best people to advise you as to the wiring arrangements. Regards, Me. I heat our home with cold draughts and cook food with magnets! Darren (myenergi) 27 Jan 2026, 15:53 GMT Hi xxxx, Its not a difficult thing to connect the output of the eddi to the sunamp, its just 3 wires. I can't believe he has got it wrong, but the sunamp should be connected to a permanent 240v supply, as you have started, so if the eddi was turned off, you should still have power lights on the sunamp. I dont think this is the case at the moment is it? It is only authorised people allowed to swap our units, but thats something we organise after we have diagnosed the issue over the phone. Do you know how cinergi wired it up so it could be used whilst the eddi was being reinstalled? I wonder if this rewiring is what could be what is causing the issue, now the eddi has been reinstalled. There should be a cable going to the sunamp, to power it, and a cable going from the eddi to the sunamp, which will allow the eddi to send power to the heater inside. Darren Me 27 Jan 2026, 14:37 GMT Hello Darren, I have been explaining all along that the Sunamp requires two Live feeds to function correctly - and this is precisely how it has been wired from the start. When the Eddi became a dead Eddi, I called out Cirnergi as your website makes it quite clear that only authorised agents (of which Cirnergi is one) are the only persons to work on the Eddi unit. When Cinergi carried out the installation, their electrician wired the two systems together and also set up the WiFi etc. so that I could then programme in my requirements. As to the relay board, this is to control power to a dual fuel towel rail - but this circuit is switched off at present as the heat pump is warming the towel rail. I have used the isolation switch leading to the bathroom that was wired in by Cinergi for this and it has been turned off for some weeks. I cannot see where to re-programme those settings in the Eddi screen menus and may need help with this later please as they seem to have changed. Maybe as the fitter knows nothing about the settings (as he informed me) then maybe this needs to be sorted out later. When Cinergi attended the dead Eddi, the electrician carried out a temporary wiring arrangement to allow us to continue using hot water. I informed Matt your fitter when he attended last Friday that this was the case; I then assumed he knew what wiring had to be done to return the system to normal with the new Eddi. Matt obviously didn’t carry out a test or he would have found the system was not functioning fully. Calling out Cinergi to ascertain where the fault lay has cost me £210 - over a fortnight later, I still do not have a working system. May I suggest if your fitter doesn’t know how to connect an Eddi to a Sunamp Thermino ePC210, then you ask for assistance from your authorised agent Cinergi as their electrician does! Regards, Me I heat our home with cold draughts and cook food with magnets! Darren (myenergi) 27 Jan 2026, 14:03 GMT Hi xxxx, Apologies for these issues. just to confirm, when the eddi is in bypass mode, the electronics bypass the eddi completely, and it puts 240v on its output. The warranty installer would have swapped the eddi and connected the wires to the new one, the same as the old one. The sunamp does need its own 240v supply, so power it, and the eddi connects to the heater inputs, and the sunamp will then control how much power the eddi can put in. If the sunamp only lights up when the eddi is in bypass mode, then that would suggest it hasnt been wired like this. Im not sure how the eddi could have been set up to power the sunam,pom in this way. There was a relay board connected to the old eddi, and this has been put into the new eddi, but its not been set the same as the old relay board was. Do you know what the relay board is being used for as it had a timed boost set for it in the last eddi? Darren Me 27 Jan 2026, 12:17 GMT Hello Dave, I have heard no more from you all morning, what are you doing to progress this repair please? It is now 2 full weeks since I contacted MyEnergi to resolve this failed Eddi unit and from my point of view, I am worse off than when the Cinergi electrician left on that Wednesday as at least he had arranged it so as to continue supplying me with hot water. Before leaving the electrician informed me that you would not make arrangements to repair/replace the Eddi through Cinergi and that I must establish contact myself. Making contact with MyEnergi ranks along with pulling teeth as I was forced to engage with you AI ChatBot! If I have not heard back from you by 4 pm today Wednesday 27th. January, I will be putting all the sorry details in a report to RenewableEnergyHub Forum for other potential users to comment on and the matter will. be escalated to MyEnergy Management - yhis is no way to run a business! Regards, Me I heat our home with cold draughts and cook food with magnets! Me 27 Jan 2026, 10:41 GMT Dave, I reiterate: There should be glowing LED’s at all times on the Sunamp unit, there are not. The LED’s are powered from a separate ‘always on’ live from the grid supplied presumably from a live buss on the Eddi. There is then a second switched live for the jeater load. The only time the LED’s light is when Bypass or a heat command is sent. Bypass allows the LED’s to stay on but supplies no heat. Heat command lights the LED’s for a few seconds, then they go off again. Regards, Me I heat our home with cold draughts and cook food with magnets! Me 27 Jan 2026, 10:17 GMT Bypass switch (as beforte) lights the LED’s but no power flows and I just noticed you tried the same thing and as before the LED’s light for a few seconds ND THEN EXTINGUISH AGAIN. BTW, IT DOESN’T ALWAYS INDICATE ‘MAX TEMP REACHED’ SOMETIMES I JUST SEE THE PAUSED SYSMBOL NEXT TO THE ICON. Me I heat our home with cold draughts and cook food with magnets! Me 27 Jan 2026, 10:07 GMT Hello Dave, I have already performed these tests, there is no consumption, the water is not heated when passing through the Sunamp. The Sunamp worked fine when Cinergi wired it for a temporary ‘override’ so that I could turn it on and off (tariff rates apply!) and I don’t think Matt has wired it up as it should be. All worked to provide hot water right up until the time that Matt fitted the new Eddi. There are two live feeds for the Sunamp and I think these have not been wired correctly by Matt. Please sort this out quickly, for all the reasons I have explained before. Me I heat our home with cold draughts and cook food with magnets! Dave (myenergi) 27 Jan 2026, 09:56 GMT Good morning Mike,
Thank you very much for your response and for providing the serial number. I have tested the Eddi this morning, and it immediately displayed a "Max temp reached" message. Could you please confirm whether your water is hot? If it is not, kindly move the rocker switch located on the right-hand side at the bottom of the Eddi and verify with your smart meter that you are drawing 3 kW. If you are not, the thermostat connected to the element may have tripped, which could be preventing the Eddi from diverting properly.
best wishes Dave |

Chris Davis (myenergi) 12 Feb 2026, 13:35 GMT
Hi xxxx,
Good afternoon. We have nothing further to add. We asked a third-party installer to swap and set up a suspected Eddi unit, which they did. We were not aware that the wiring had been changed to the Sunamp to provide hot water, and we did not make any changes ourselves. When the third-party installer returned, they simply carried out the instructions they were given it is not their responsibility to rewire equipment that does not belong to them or to us.
Darren did, however, offer to send someone free of charge to carry out this work, which is going above and beyond. You chose for Cinergi to handle the remedial work instead. While that is, of course, your choice, it is not something we will be covering financially.
In situations like this, the standard practice is for the installer who changed the wiring to leave a note with the Eddi/Sunamp explaining what was done as a temporary fix and what will need adjusting when the unit is swapped. This was not done. The third-party installer would not have known any difference, as the Eddi would have simply switched on as normal with no indication that rewiring was required.
For context, and without being quoted on this, bypassing power to a Thermino Sunamp is relatively simple it typically involves bridging the connection inside the Eddi, bypassing the Eddi completely without touching the wiring on the Sunamp itself. If this was done, then swapping the Eddi unit should be all that is required.
Best regards,
Chris Davis |

Me 4 Feb 2026, 13:24 GMT Hello Chris, Further to my reply earlier, I would add that my first attempt at contacting MyEnergi over this whole sorry matter was on Monday 5th. January but that and all other attempts at communication until Thursday 8th. January do not show in your email trail despite the AI statements that the matter was being handed on to a human. Over subsequent days and weeks, despite pointing out that my wife and I are elderly, disabled and in need of hot water for medical reasons, your support system appears to respond at a snail’s pace. May I suggest that you review that early email content and reconsider your stance on this matter please? Regards, Me I heat our home with cold draughts and cook food with magnets! |
|
Me 4 Feb 2026, 12:00 GMT Hello Chris. I would like to point out that I attempted to contact MyEnergy at the very start and your system STRONGLY RECOMMENDS that contact should be established via the AI chatbot for the quickest resolution. The nearest I came to speaking to a human was on (I think) the third attempt when the chatbot stated I would be contacted by a human - this did not happen. I called in Cinergi as my installer and your approved supplier; the electrician established the fault was indeed with the Eddi. He effected a bypass so that we would still have hot water. When I eventually established contact with a human several days later after many attempts to do so, I was informed a replacement unit would be sent out and this happened several days later. The replacement unit arrived on the following Monday and then I awaited advice of when the fitter would be coming. I then heard that the fitter would come on that Wednesday. He failed to arrive. He then promised to come on the Thursday and failed to do so. He finally came on the Friday. I informed him that the Cinergi electrician had made a temporary link so that we might continue to have hot water available. The Cinergi electrician did not touch or reconfigure the Harvi’s or CT clamps in any way but I understand all the settings would have been lost when the Eddi failed. The fitter (Matt) informed me he would rewire the Eddi but he did not mention that he would not rewire to connect the Sunamp Thermino system. Matt obviously did not test the system as after he left leaving me to try and set up a schedule using the MyEnergy app, I found that I could not heat the water - even by switching the Eddie to ‘Byoass’. This as it turned out wass because the wiring had not been connected as required for a Sunamp. Incidentally, much time and effort was expended over this wiring and Cinergi even sent the Support team the details for the correct connections for this purpose. I would also point out that the reason the Cinergi electrician made a temporary connection for me so as to provide hot water was that the bypass switch on the faulty Eddi did not work. The switch will not engage in the bypass position. Had the Cinergi electrician not made a temporary connection, we would have been without hot water throughout this whole event. As mentioned. I endeavoured to contact your company and was frustrated by the AI chatbot failing to connect me with a person. All attempts were subject to extended delays and even at the time that Darren might arrange a further visit from a fitter, no timescale was mentioned at all and we were still without hot water! I have had numerous emails and have replied to Darren making changes to the Eddi settings as these were not made whilst Matt was here as he informed me he had nothing to do with the settings. Regards, Me I heat our home with cold draughts and cook food with magnets! |

Chris Davis (myenergi) 4 Feb 2026, 11:27 GMT Hi there Chris here, the Customer Experiance Manager.
I’m very sorry to hear about the recent failure of your Eddi. When issues like this arise, we would always recommend contacting us in the first instance so that we can assess the fault and arrange an installer where required.
I understand that you chose to arrange your own installer, which of course is your decision, but any costs incurred in doing so would be payable by yourself. From what we can see, the person who attended confirmed the Eddi was faulty and rewired the Sunamp to provide you with hot water, which is completely understandable everyone needs hot water.
The issue arose because when we subsequently sent an engineer to replace the Eddi, we were not aware that the wiring configuration had been altered. Our instruction to the third-party installer was to carry out a straight swap and setup of the Eddi, not to reconfigure or modify any existing wiring. As a result, this part of the work is not something we are liable for, as it was not changed by us.
As Darren mentioned previously, we were more than happy to send an installer to reconfigure the cabling as a goodwill gesture, in that you did not take Darren up on this offer is entirely your choice but again means payment to your chosen installer would be payable by you.
In addition, regarding the positioning and setup of the CT clamps, I have spoken with Darren and he is going to help ensure these are checked and corrected if required. As a further goodwill gesture, I am also happy to send an installer to rectify this aspect if needed.
Please note that we are not liable for incorrect CT clamp setup, so any work carried out in this regard would be purely as a goodwill gesture on our part.
Please let me know how you’d like to proceed.
Chris Davis |

Me 4 Feb 2026, 11:09 GMT done. Me I heat our home with cold draughts and cook food with magnets! |
|
Darren (myenergi) 4 Feb 2026, 11:04 GMT Hi xxxx, coud you try this please. Could you go into the eddi menu again, device settings, installer settings,(password0000), linked devices, devices, harvi 1443293, and set ct1 and 2 to ac battery please. It looks like you might be producing 900w of solar right now, and the batteries arent doing anything. Darren |
|
Me 4 Feb 2026, 10:39 GMT Darren, The solar harvest now exceeding the consumption, here are 3 mor screen grabs for you. Regards, Me. I heat our home with cold draughts and cook food with magnets! |
|
Me 4 Feb 2026, 10:32 GMT Hello Darren, The battery will at present, supply any power above that which the solar panels are providing and of course changes dynamically. I have just sent some more screen grabs showing Enphase app readings too. Matt did go to the 2nd Harvi and I think I heard him removing some plastic trunking covers to ascertain which CT clamp went where. There are two black lead CT clamps and one grey one. The grey lead enters the middle access hole on the Harvi. The battery will continue to work with solar power as available until 13:00 when the tesla app will conect to grid to top up the charge again. Regards, Me. I heat our home with cold draughts and cook food with magnets! |
|
Me 4 Feb 2026, 10:26 GMT Hello Darren, Voracity Check: The attached 3 screenshots were all taken within seconds of each-other and suggest that any erronous reading is with the Eddi; both Tesla and Enphase apps are in agreement on solar production. Regards, Me I heat our home with cold draughts and cook food with magnets! |
|
Darren (myenergi) 4 Feb 2026, 10:25 GMT Hi xxxx, The solar reading being off a little? Is it still off now? There are 3 ct's set to generation only, and im not 100% sure it is set correctly as i know you only have 2 solar systems. One of these ct's should be set to ac battery. Is your powerwall battery doing anything at the moment, or is it idle? Darren |
|
Me 4 Feb 2026, 09:43 GMT Hello Darren The attached were captured within seconds of eacother just minutes ago as we have some sun this morning! Regards, Me. I heat our home with cold draughts and cook food with magnets! |
|
Darren (myenergi) 3 Feb 2026, 16:11 GMT Hi xxxx, Thank you for clarifying. I do believe you that the eddi bypass switch didnt work correctly. It is an odd fault to have on an eddi, but when we get it back here, it will get looked at. Darren |
|
Mike McMillan 3 Feb 2026, 15:33 GMT Darren, I attempted to send you this message along with a short video of me attempting to operate the bypass switch but it was rejected by your system. Thr fact remains, the Eddi would not allow bypass mode to be used. “ Darren, The failed Eddi was picked up by Royal Mail today; I’m attaching a short video of me attempting to use the bypass switch which will not engage for me. I have no idea whether it ever worked as I don’t believe I have ever had need to use it anyway. Pity it didn’t work when it was most needed. Regards, Me I heat our home with cold draughts and cook food with magnets! |
|
Me 3 Feb 2026, 15:09 GMT Darren, This is how the display looked one day last year and may give you some ideas. Me I heat our home with cold draughts and cook food with magnets! |
|
Me 3 Feb 2026, 15:00 GMT Yes, there was an icon rather like a battery in appearance; it was in a position of about 7. O clock on the display. and it did indicate flow to or from. Me I heat our home with cold draughts and cook food with magnets! |
|
Darren (myenergi) 3 Feb 2026, 14:53 GMT Hi xxxx, That symbol that was on the myenergi app earlier wasnt a battery icon, it was a storage icon, which is for a 3rd party device like your eddi. Did you have one on there before the eddi was swapped out? Darren |
|
Me 3 Feb 2026, 14:40 GMT We seem to have lost any battery sensing on the MyEnergy app - it was on the display before! Regards, Me I heat our home with cold draughts and cook food with magnets! |
|
Me 3 Feb 2026, 14:30 GMT The Powerwalls ease off on the final few percent of charging and I’m attaching a more recent screenshot now. I heat our home with cold draughts and cook food with magnets! |
|
Darren (myenergi) 3 Feb 2026, 14:17 GMT Hi xxxx, Im only seeing 1.3kw coming from the grid. Has the import dropped? Darren |
|
Me 3 Feb 2026, 14:11 GMT Right, that Harvi has been reset to grid and the other Harvi now has all thre CT’s showing Generation Only. (I did not alter the second or third ones, they were already set like that). The grid is charging the battery at present. I use Octopus Cosy and 13:00 - 16:00 is the cheap rate time. Regards, Me I heat our home with cold draughts and cook food with magnets! |
|
Darren (myenergi) 3 Feb 2026, 13:57 GMT Hi xxxx, Apologies, could you set that ct back to grid please in harvi 1047349, and in the other harvi , 1443293, set ct 1 to generation only. Are the powerwalls discharging to the grid at the moment? Darren |
|
Me 3 Feb 2026, 13:39 GMT Hello Viktoriia, Royal Mail have collected the parcel now and I have received a receipt from them by email. Regards, Me I heat our home with cold draughts and cook food with magnets! |
|
Me 3 Feb 2026, 13:37 GMT Hello Darren, I have changed the Harvi (the top one on the list) so that CT1 is set to Generation Only. I am attaching screenshots taken within seconds of eacother of the Tesla and MyEnergi apps. It may not be relevant but, when Matt wired up the warranty replacement Eddi, he asked me if the two Harvi’s were on the same channel; as I didn’t know I had to leave him to work that out for himself. Regards, Me I heat our home with cold draughts and cook food with magnets! |
|
Darren (myenergi) 3 Feb 2026, 12:15 GMT Hi xxxx, What is the battery app and myenergi showing as solar production. Are they reading the same? Could you go to your eddi please and go into the menu, device settings, installer settings (password0000), linked devices, devices, harvi, and set ct1 to generation only as well please. Darren |
|
Me 2 Feb 2026, 17:12 GMT Darren, I will endeavour to do so, the greatest variable is ‘If the sun shines at all’ under current weather conditions! Regards, Me. I heat our home with cold draughts and cook food with magnets! |
|
Darren (myenergi) 2 Feb 2026, 17:02 GMT Hi xxxx, When you look at the tesla app, maybe tomorrow now, and you can see the solar production on there, does that show the same as the myenergi app? I can see there are 2 ct's set to generation only, so i can only assume these are both monitoring your individual solar productions, going to the inverter for each powerwall. Its hard to tell now as its dark, so tomorrow, when its sunny and both your panels are producing, if you can tell, could you send me a screenshot of the tesla app and the myenergi app please. Darren |
|
Me 2 Feb 2026, 15:51 GMT Darren, As I stated, they are Powerwall 2’s. Please clarify the second question. Regards, Me I heat our home with cold draughts and cook food with magnets! |
|
Darren (myenergi) 2 Feb 2026, 15:48 GMT Hi xxxx, The harvi is set a little oddly as i dont think it should have a storage ct set in it. Are they a powerwall 2 or 3 though? Does the solar production value show corerctly when they are just ion their normal modes? Darren |
|
Me 2 Feb 2026, 15:41 GMT Hello Darren, Firstly, the Powerwall battery, this is a 27 kWh system comprising 2 x Powerwall 2’s. The solar array has two ‘down pipes’ so to speak as we have 9 panels across 2 roofs on one feed into the Gateway and the other has 12 panels including 10 in the garden and these all feed into the second MTTP in the Gateway. The display used to tally fairly closely on the Tesla and MyEnergy apps. Regards, Me I heat our home with cold draughts and cook food with magnets! |
|
Darren (myenergi) 2 Feb 2026, 15:27 GMT Hi xxxx, Is it a powerwall 2 or 3? If its a powerwall 3 then these readings may be correct. I can see one of the ct's in the harvi is set to storage only. Im unsre what this is monitoring. Do you have 2 solar systems? Darren |
|
Me 2 Feb 2026, 14:34 GMT Hello Darren, I mentioned that the Eddi app was displaying nonsense values and I attach images to indicate this. In case you are unfamiliar with the Tesla app, here are the values which I find are very close to being realistic and over time, they appear to be moderately accurate; this indicates to me that the Harvi reports are erroneous at present. This is particularly so when the power appears to be being sent to the solar panels as in this screenshot. The two were taken within less than 2 seconds of each other. Tesla: Solar 0.3 kW. output, Domestic draw 1.4 kW. and Powerwall charging at 4.9 kW. (I realise that MyEnergi do not have the means to monitor the Powerwall setup but at least used to indicate the flow reasonably accurately) and the draw from Grid = 6.0 kW. I will leave you to see what the Eddi thinks it is! Regards, Me.

Darren (myenergi) 30 Jan 2026, 16:16 GMT Hi xxxx, Ill pass on to Viktoria. Darren |
|
Me 30 Jan 2026, 15:37 GMT Darren, This is what I sent to Viktoriia: Regards, Me I heat our home with cold draughts and cook food with magnets! |
|
Me 30 Jan 2026, 15:05 GMT Hello Darren, Ok, I did wonder, thank you for that. I have just tried to contact Viktoriia as the link she provided to arrange return of the faulty Eddi doesn’t provide the facility to arrange the return with RM picking up the parcel and bringing a label with them. The message has been rejected as the docket is now out of date it seems. I would like to have the parcel picked up on Monday as I will not be here tomorrow. Regards, Me I heat our home with cold draughts and cook food with magnets! |
|
Darren (myenergi) 30 Jan 2026, 14:38 GMT Hi xxxx, Once its up to temp, it will try to check it every 10 minutes or so to see if it still needs heating. Thew sunamp does have the effect of it getting to temp, then asking for power a little later. The specific settings that were originally put in for the sunamp have been superceeded by setting the icon to heat battery. Darren |
|
Me 30 Jan 2026, 14:02 GMT Now charging again @2.8 kW. Me I heat our home with cold draughts and cook food with magnets! |
|
Me 30 Jan 2026, 13:53 GMT Just looked at the Givenergi app on my phone again and it indicate ‘Max Temp Reached’, this suggests to me that the system is not checking the charge level (or temperature?) as it used to on the first Eddi. I will be packing up that one for return later today. Regards, Me I heat our home with cold draughts and cook food with magnets! |
|
Me 30 Jan 2026, 13:50 GMT Hello Darren, As directed, I have now set to Heat Batt. I notice that the programmed charge schedule still displays in the app but charging has stopped though the Sunamp needs far more charging as yet. The sunamp power LED is lit but neither of the ‘level of charge’ LED’s are glowing yet. Regarding the CT’s. One harvi is next to the consumer unit and I far as I know monitors grid. The other Harvi has a CT clamp on the solar panel output, and the other CT clamp goes to the Tesla Powerwall (x2). There is still no charge going to the Sunamp - does something need re=pragramming? Regards, Me I heat our home with cold draughts and cook food with magnets! |
|
Darren (myenergi) 30 Jan 2026, 13:03 GMT Hi xxxx, Great news. I have replicated the boost times to turn the towel rail on at 1915 for 3 hours for relay 2. Both harvis are set in the menu. One of the harvis has the grid ct connected, and the other has a storage ct and 2 generation ct's conencted. is this correct? Could you go inot the eddi menu please, device settings, display, icons, heater 1, press tick and use the up and down arrow to set it to heat batt. This is specific for the sunamp. Darren |
|
Me 30 Jan 2026, 11:44 GMT Darren, One more thing, the display is indicating ‘MAX TEMP REACHED’; this is after one hours charging at ~3 kW, as this is obviously not a full charge from ambient cold room temperature, I trust it will start charging properly on my scheduled times? I have a scheduled time of 13:00 - 16:00 today and this will confirm whether the MAX TEMP settings are set to recheck for ‘topping-up’ after a set interval. Regards, Me. I heat our home with cold draughts and cook food with magnets! |
|
Me 30 Jan 2026, 11:35 GMT Darren, This to let you know that Cinergi have now wired up the Eddi to the Sunamp Thermino and our DHW is heating up at long last. There are a number of settings to be adjusted please; I know little about how to set them but remember that a parameter needs to be set for Eddi to check with Sunamp to retry charging after a set interval as the heat dissipates into the PCM in the heat battery. I note also that there are no settings on the Harvi CT clamps yet, the lines for these are blank still. I wish to set up my towel rail heater which I understand is wired to Relay 2 but I cannot see any settings to programme for this; I would be grateful for instructions on the procedure for this please. I also note that the status display in the app does not reflect reality at times. Are the erroneous readings perhaps due to the CT clamps not been configured yet? I look forward to hearing from you please. Regards, Me I heat our home with cold draughts and cook food with magnets! |

Darren (myenergi) 29 Jan 2026, 16:45 GMT Hi xxxx, Ive said i will organise an installer to rectify the wiring. We cant pay any compensation im afraid. Darren |
|
|
Me 29 Jan 2026, 15:12 GMT Darren, I think I have made it abundantly clear that we have a need for hot water without delay; you wrote that you would only wire the Eddi as you seem to think it should have been wired. To my way of thinking, this was all you were prepared to do and so I have requested the services of Cinergi to return to the normal operating status we enjoyed previous to the failure. As for you stating it would not cost us anything - it has already cost me £210 and I appear to be without any hot water for the foreseeable future as you show no intentions of wiring the Sunamp as it was previously. We can sort out how you compensate us later please. Regards, Me I heat our home with cold draughts and cook food with magnets! |
|
Darren (myenergi) 29 Jan 2026, 14:54 GMT Hi xxxx, They will charge you, and i can send one of our guys out to change the wing over, so it wont cost you anything. Im hoping the bypass swicth works on this one? Darren |
|
Me 29 Jan 2026, 13:33 GMT Darren, After your previous correspondence in which you appear to have washed your hands of the whole wiring issue as we should have used the ‘Bypass’ switch rather than making temporary wiring to allow the Sunamp to charge, I have requested Cinergi to visit tomorrow to connect the warranty Eddi so that it will work. I would remind you that the ‘Bypass’ switch does not work and just returns to the off position as soon as it is released. I agree with you -this should not have cost us a penny. I did endeavour to establish contact with you via your AI chat bot but with very little success. Regards, Me I heat our home with cold draughts and cook food with magnets! |
|
Darren (myenergi) 29 Jan 2026, 13:07 GMT Hi xxxx, I will have to raise another ticket to get an engineer organised. Just for future reference, any issues, please come directly to us. We can diagnose issues over the phone and then organise everything thats needed. This shouldn't have cost you a penny. Darren |
|
Me 29 Jan 2026, 10:19 GMT Hello yet again Darren, The electrician has explained how the Sunamp was powered using connections within the Eddi, why is this not clear to you? To me that sounds like standard electrical practice! If you are not going to solve this problem out then I will take the matter further and your Directors will be hearing from us. A warranty repair that has cost me £210 just to determine tha fault lies within the Eddi and now you seem to think I should pay out to connect the warranty replacement. May I remind you the electrician had to use a temporary just to keep hot water supply going as the Eddi could not be set to Bypass? Regards, Me I heat our home with cold draughts and cook food with magnets! |
|
Darren (myenergi) 29 Jan 2026, 10:07 GMT Hi Rebecca, we wouldnt be able to cover this cost unfortunately as it wasnt us who made the changes. Our warranty installers will just replace the unit like for like and set up as the old one was. He was unaware of any rewiring that had happened. Darren |
|
Rebecca Churn 29 Jan 2026, 09:47 GMT Good morning Darren,
This can be arranged but it would be to a further cost to Mr xxxxxx. Will the bill be covered by Myenergy if we go back out to rectify this?
Kind regards |
|
Me 29 Jan 2026, 09:18 GMT My last email was for Darren and copied to you Rebecca, from the wording of Darren’s last note, would I be right in thinking that he is requesting that Cinergi might call and rectify this mess please? Regards, Me I heat our home with cold draughts and cook food with magnets! |
|
Me 29 Jan 2026, 09:10 GMT Hello Darren and Rebecca, The Cinergi electrician had no choice if we were to be provided with hot water until the time Matt came; the ‘Bypass’ switch would not engage, it just flipped back to the off position every time. Through the kindness of the Cinergi electrician, we had hot water on a temporary basis. Now, we have no hot water and have not had since Matt visited. May I remind you that (as I have mentioned in previous emails, my wife and I are disabled, elderly and have special medical needs - these are not being helped by a lack of hot water supply! I hope I will be hearing from you about a technician/engineer coming to rectify the problem today please? Regards, Me I heat our home with cold draughts and cook food with magnets! |
|
Darren (myenergi) 29 Jan 2026, 08:53 GMT Hi Rebecca, Thank you for confirming. You are correct, this is where the eddi warranty installer may not have realised,as he will only be sent to replace the eddi like for like. So can you confirm what needs to be done. Does the brown permanent live need to go back into the fused spur to power the sunamp, as our warranty installer wont have done this. The faulty eddi could have been put into bypass mode when the issue occurred which would have kept it heating until the new eddi could be fitted. Would it be possible to return and rewire as it was originally please? Darren |
|
Me 28 Jan 2026, 10:35 GMT The email was for you CC’d to Rebecca. I heat our home with cold draughts and cook food with magnets! |
|
Darren (myenergi) 28 Jan 2026, 10:32 GMT Hi xxxx, Apologies, that message was for Rebecca, but the reaply is not visible by yourself. Darren |
|
Me 28 Jan 2026, 10:27 GMT May I suggest you ask Matt if he saw some Wago connectors on the lead please? Regards, Me I heat our home with cold draughts and cook food with magnets! |
|
Me 28 Jan 2026, 10:26 GMT The electrician mentioned to me that he was going to his van for some Wago connectors - could this be what you are asking? Me I heat our home with cold draughts and cook food with magnets! |
|
Darren (myenergi) 28 Jan 2026, 10:23 GMT Hi, Can I ask how it was heating the water without the eddi being connected, as the eddi supplies the power to the heaters. If it was connected to the mains, this may have needed to be removed when the eddi was installed? Darren |
|
Me 28 Jan 2026, 10:17 GMT Darren, As I have pointed out, I am not an electrician but… is it not possible that the cable from the Sunamp carries sufficient cores to provide two live connections - one from the supply into the Eddie and the other through the switched circuit? I can only see one lead between the Sunamp and Eddi. Regards, Me. I heat our home with cold draughts and cook food with magnets! |
|
Darren (myenergi) 27 Jan 2026, 16:16 GMT Hi Rebecca, I wonder if you could help me. I believe you have had an installer go back to one of our joint customers' sites, to deal with an eddi issue. You have diagnosed the eddi as being faulty and we have sent a new one out, to replace it., which ahs been done. Its not heating the customers water through his sunamp heat battery. I believe the installers wired it in a way so the custoemr, xxxxxx could still have hot water while the eddi was being replaced. It looks like the sunamp isnt getting a 240v supply to it, and i wonderd if you could ask the installers where the permanent 240v supply for the sunamp comes from as the sunamp only seems to light up when the eddi is supplying 240v to it.

Darren (myenergi) 27 Jan 2026, 16:02 GMT Hi, Can I have their email address please and ill cc them into this conversation Darren |
|
Me 27 Jan 2026, 15:59 GMT Hello Darren, I am not an electrician and employed Cinergi (as the agent for both MyEnergi products and Sunamp). As I have already suggested, Cinergi electricians are the best people to advise you as to the wiring arrangements. Regards, Me I heat our home with cold draughts and cook food with magnets! |
|
Darren (myenergi) 27 Jan 2026, 15:53 GMT Hi, Its not a difficult thing to connect the output of the eddi to the sunamp, its just 3 wires. I can't believe he has got it wrong, but the sunamp should be connected to a permanent 240v supply, as you have started, so if the eddi was turned off, you should still have power lights on the sunamp. I dont think this is the case at the moment is it? It is only authorised people allowed to swap our units, but thats something we organise after we have diagnosed the issue over the phone. Do you know how cinergi wired it up so it could be used whilst the eddi was being reinstalled? I wonder if this rewiring is what could be what is causing the issue, now the eddi has been reinstalled. There should be a cable going to the sunamp, to power it, and a cable going from the eddi to the sunamp, which will allow the eddi to send power to the heater inside. Darren |
|
Me 27 Jan 2026, 14:37 GMT Hello Darren, I have been explaining all along that the Sunamp requires two Live feeds to function correctly - and this is precisely how it has been wired from the start. When the Eddi became a dead Eddi, I called out Cirnergi as your website makes it quite clear that only authorised agents (of which Cirnergi is one) are the only persons to work on the Eddi unit. When Cinergi carried out the installation, their electrician wired the two systems together and also set up the WiFi etc. so that I could then programme in my requirements. As to the relay board, this is to control power to a dual fuel towel rail - but this circuit is switched off at present as the heat pump is warming the towel rail. I have used the isolation switch leading to the bathroom that was wired in by Cinergi for this and it has been turned off for some weeks. I cannot see where to re-programme those settings in the Eddi screen menus and may need help with this later please as they seem to have changed. Maybe as the fitter knows nothing about the settings (as he informed me) then maybe this needs to be sorted out later. When Cinergi attended the dead Eddi, the electrician carried out a temporary wiring arrangement to allow us to continue using hot water. I informed Matt your fitter when he attended last Friday that this was the case; I then assumed he knew what wiring had to be done to return the system to normal with the new Eddi. Matt obviously didn’t carry out a test or he would have found the system was not functioning fully. Calling out Cinergi to ascertain where the fault lay has cost me £210 - over a fortnight later, I still do not have a working system. May I suggest if your fitter doesn’t know how to connect an Eddi to a Sunamp Thermino ePC210, then you ask for assistance from your authorised agent Cinergi as their electrician does! Regards, Me I heat our home with cold draughts and cook food with magnets! |
|
Darren (myenergi) 27 Jan 2026, 14:03 GMT Hi, Apologies for these issues. just to confirm, when the eddi is in bypass mode, the electronics bypass the eddi completely, and it puts 240v on its output. The warranty installer would have swapped the eddi and connected the wires to the new one, the same as the old one. The sunamp does need its own 240v supply, so power it, and the eddi connects to the heater inputs, and the sunamp will then control how much power the eddi can put in. If the sunamp only lights up when the eddi is in bypass mode, then that would suggest it hasnt been wired like this. Im not sure how the eddi could have been set up to power the sunam,pom in this way. There was a relay board connected to the old eddi, and this has been put into the new eddi, but its not been set the same as the old relay board was. Do you know what the relay board is being used for as it had a timed boost set for it in the last eddi? Darren |

Me 27 Jan 2026, 12:17 GMT Hello Dave, I have heard no more from you all morning, what are you doing to progress this repair please? It is now 2 full weeks since I contacted MyEnergi to resolve this failed Eddi unit and from my point of view, I am worse off than when the Cinergi electrician left on that Wednesday as at least he had arranged it so as to continue supplying me with hot water. Before leaving the electrician informed me that you would not make arrangements to repair/replace the Eddi through Cinergi and that I must establish contact myself. Making contact with MyEnergi ranks along with pulling teeth as I was forced to engage with you AI ChatBot! If I have not heard back from you by 4 pm today Wednesday 27th. January, I will be putting all the sorry details in a report to RenewableEnergyHub Forum for other potential users to comment on and the matter will. be escalated to MyEnergy Management - yhis is no way to run a business! Regards, Me I heat our home with cold draughts and cook food with magnets! |
|
Me 27 Jan 2026, 10:41 GMT Dave, I reiterate: There should be glowing LED’s at all times on the Sunamp unit, there are not. The LED’s are powered from a separate ‘always on’ live from the grid supplied presumably from a live buss on the Eddi. There is then a second switched live for the jeater load. The only time the LED’s light is when Bypass or a heat command is sent. Bypass allows the LED’s to stay on but supplies no heat. Heat command lights the LED’s for a few seconds, then they go off again. Regards, Me I heat our home with cold draughts and cook food with magnets! |
|
Me 27 Jan 2026, 10:17 GMT Bypass switch (as beforte) lights the LED’s but no power flows and I just noticed you tried the same thing and as before the LED’s light for a few seconds ND THEN EXTINGUISH AGAIN. BTW, IT DOESN’T ALWAYS INDICATE ‘MAX TEMP REACHED’ SOMETIMES I JUST SEE THE PAUSED SYSMBOL NEXT TO THE ICON. MIKE I heat our home with cold draughts and cook food with magnets! |
|
Me 27 Jan 2026, 10:07 GMT Hello Dave, I have already performed these tests, there is no consumption, the water is not heated when passing through the Sunamp. The Sunamp worked fine when Cinergi wired it for a temporary ‘override’ so that I could turn it on and off (tariff rates apply!) and I don’t think Matt has wired it up as it should be. All worked to provide hot water right up until the time that Matt fitted the new Eddi. There are two live feeds for the Sunamp and I think these have not been wired correctly by Matt. Please sort this out quickly, for all the reasons I have explained before. Me I heat our home with cold draughts and cook food with magnets! |
|
Dave (myenergi) 27 Jan 2026, 09:56 GMT Good morning xxxx
Thank you very much for your response and for providing the serial number. I have tested the Eddi this morning, and it immediately displayed a "Max temp reached" message. Could you please confirm whether your water is hot? If it is not, kindly move the rocker switch located on the right-hand side at the bottom of the Eddi and verify with your smart meter that you are drawing 3 kW. If you are not, the thermostat connected to the element may have tripped, which could be preventing the Eddi from diverting properly.
best wishes Dave |
|
Me 26 Jan 2026, 16:32 GMT I am beginning to run out of patience - and I do not understand this very long winded method of attempting to deal with my problem Eddi by just sending me sympathetic templated replies that appear to make no progress. Me I heat our home with cold draughts and cook food with magnets!

@swwils, it’s an odd one, but since late last year I’ve noticed far fewer posts from Jordan Brompton, co-founder of MyEnergi. They were incredibly active on social media throughout much of last year… lots of updates about growth, new products, events, you name it, but things have gone noticeably quiet in recent months.
Meanwhile, the level of customer service extended to @toodles is pretty appalling.
To me, ever since they came on my radar a couple of years ago, MyEnergi comes across as a very flashy company when it comes to marketing and events… they sponsor racing teams, sports sponsorships, big launches, big stands at trade shows, etc., so clearly they’re splashing the cash in those areas and loving business life.
Yet when it comes to aftercare and support for existing customers, it feels like that side of things is almost non-existent.

@editor I'm not a business analyst. I don't know what the history of it is, why is the immersun so similar to the eddi? The eddi had LED flicker on release well into v2. The eddi didnt even have agile scheduling (only boost) for ages. The Zappi got "updated" to a "GLO" version after years with essentially nothing new. No DC charger released. No V2G solution. The Libbi is just some rebranded thing with not even a great inviter match for UK solar installs. They had some massive in house PCB production line to produce PCBs for zappis?? What?? It looked like they could easily do 10,000 assemblies a month with what they bought in, where are all those chargers going??? What happens when grants dry up? Is it even possible to be a "dyson" of EV charging? I dont think so!
Compare them to someone like sigenergy and there is a real difference in exciting new products and capabilities being brought to our tricky island market.

This is a fascinating comment, in light of me going back to look at Jordan’s posts on LinkedIn an hour ago. What I noticed (without even giving it a second thought until I saw your comment) was that, prior to founding Myenergi, Jordan was Sales Director at immerSUN. 🤔
