@potatoman on Homely Connect web page after login, go to History for the graphs page.  On that you will probably have the default flow temperature selected, just choose to add the Heating [ON/OFF] element. Look at the base of the graph and count how many cycles are happening over the period of one day. It can be hard to see with the free version having a fixed timescale, but you can still tell if there are loads and loads of on/offs.

@el_presidente /Tooddles thank you for your reply, I have eventually found what I was supposed to find, can you tell me what you think, thanks

It doesn't seem to be doing lots of on/off cycles in any one hour so my guess is that is fine. But the behaviour of your heat pump will be determined by your own very unique set of design/install/operation and conditional circumstances. If you are concerned then you need the views of a pro.

@el_presidente Hi thanks for your reply, No I am not concerned, I just want to try and interpret the all information available correctly to see if I need to be concerned

Morning all. How exactly did you guys get access to the Homely connect app? I have emailed them but they don't seem too great at replying to email queries (I'm using team@homelyenergy.com) and the bare bones functionality and info provided by the homely customer app is irritating...

@benson Hi, for me, I made it a condition of the installation that I got access to the installer app, You could just ask your installer for the login details. If that doesn't work, because you will get access to all his installs, set up a new email address, then ask your Installer to just change the login details of just your install, so you will have a new email and password for your account which you will then be able to access.

How long have you had the Homely, are you on Octopus Cosy with it, are you happy with it, mine has only been for a few days

@potatoman that makes sense. we haven't had the official handover and commissioning completed yet on our install (I'm not entirely convinced it is ever going to happen to be honest)....but I can try and ask.

We've only had it up and running for a couple of weeks but so far my initial observations would be that our house is comfortable and a nice steady temperature. It is definitely running more efficiently now that we have left it for a couple of weeks so I can see why homely (and installers) are reticent in provide anything other than the basic ability to schedule heating and hot water but not least due to the issues we've had with our installers I don't want to be in a position where I don't have access to the installer app before paying the final invoice.

One example is the design temp. Our installers said this was all designed at 45 when quoting for our system but I noticed that the homely had been set up at 50. When I queried this they said they'd done this intentionally for the first couple of weeks and then the homely would find it's own max flow temp which would be lower than this- I'm not entirely sure how accurate this is to be honest but I'd want to be able to see this sort of thing.

@benson ‘Tis true Benson, I have been using Homely for a year now, (my review will appear in this august organ any day now) During the initial ‘learning period’, Homely will run the parameters to establish the requirements of your home, weather, heat loss etc., after this, it will settle down and you will probably see the flow temperature drop until Homely establishes your precise needs. On the matter of access to the data via the Dashboard or the Installer’s app, I have discussed this with Homely and yes, they are trying to avoid unnecessary ‘meddling’ and calls to installers from ‘the worried users’. Trust your Homely I say, (but if you can gain access to the data - this may reassure you that Homely is working efficiently!)😉.Regards, Toodles.

I have now regained access to the Homely Dashboard and have added the ‘Connect’ app and I should express my preference for the Dashbaord data display for clarity and completeness. I’m attaching a screenshot showing the last 2 days graphs for:

Set temp., actual IAT, flow temp and OAT along with COP. I select just the parameters I wish to see from a ‘reset’ as this is much easier to see. Perhaps this will give you an idea how things may settle down and… yes, I know I have possibly set a higher temperature than many might choose!

N.B. If you wish to know how to gain access to these ‘Installer only’ apps, please DM me😉 Regards, Toodles.

@toodles thanks ....no issues with the functionality and algorithms that the homely uses and I'm pleased we had it installed. Efficiency wise it is matching last years bills if we compare usage on a day to day basis but keeping our home significantly more comfortable. For example, comparing to this time last year we had our old nest thermostat and gas boiler on around 16 degrees c setback overnight and it would be quite chilly- and indeed sometimes I work nights from home which was never comfortable. But, I didn't want to put the heating on because (a) a quick blast felt inefficient and (b) it was noisy. Now I think the setback is around 19.

If we could just get access to the data to see what it is doing, it would be (for me) a significant improvement on what looks like a decent system. Despite my grumbles regarding our installer I think the basic design and proposals they came up with, and knowledge of how to set it up inclusive of how homely could benefit us, was decent enough.

Forgot to answer the Octopus cosy query above- no we are not as yet but plan to. A few ducks to get in a row first but we're getting a new (electric only) oven in a month or so's time. Then hopefully around the same time a tesla powerwall....and then we can disconnect the gas and get ourselves onto a better electric only tariff. One query I did have actually (which toodles you might be able to answer as I know you mentioned you had a powerwall, or two). If you set up the PW to align charging with the cosy tariff and perform it's sorcery with respect to predicting solar gain from the panels etc, does this then 'compete' with the settings on the homely where you can also do this and heat the home based on the triple dips i.e. do we think it is best to do one or the other, or both, if that makes sense?

@benson On the basis that the most efficient use of the grid power I need is ‘straight from the wires’ so to speak, during the 8 lowest charge Cosy hours, my Powerwalls charge and my ASHP has access to the grid and thus doesn’t have to go via the 10% loss of battery charge/discharge cycling.

The other 16 hours of the day, I am effectively off-grid for all power needs. My Tesla app is set up to charge the Powerwall battery during any and all of those 8 hours but not at any of the other 16 hours. I have the Operational Mode set for Time Based Control and have set the tariff values so that my solar PV will export (at 15 p. per  kWh) as this is marginally better than using the solar in-house as I pay 12.2 (ish) p. per kWh during the 8 Cosy cheapest hours from the grid.

I have just renewed my subscription to Homely for the Smart+ facility on the basis that although I use battery power much of the time, who knows how long we will have such a TOU tariff? Even OE still class them as experimental and as @transparent has eluded to, the TOU tariffs are not guaranteed to be around for ever. Regards, one very Cosy Toodles.
