@majordennisbloodnok Thanks for your write up. So... are you saying that both Melcloud app and Melpump app will only change something if when you go in and change a parameter, so if i use Melpump to set schedules etc, the FTC will see those commands and act on them. so if i change the temp to 22C on Melpump the FTC will use those regardless of whats on my Melcloud app? and so long as i don't change anything in Melcloud all is fine. If i happen to use Melcloud to then set temp to 19C it will act on that command aswell?

hope that makes sense?

Regards

@boycey, in your scenario if you use Melpump to change the temp then the FTC will do that. It will then immediately tell Melcloud the temp is now set to a new value, so when you go into Melcloud the temp will already show as the new correct value. If you then set it back in Melcloud, the FTC will honour that command and then report back to Melpump what the temp is now. In other words, everything will keep in sync no matter which tool you use to make the changes.

@majordennisbloodnok Thanks very much, that's cleared that up for me, it's not obvious, or i couldn't find any thing that explains that. thanks again

@majordennisbloodnok Hi, so i set my heatpump via the FTC5 back to AA, with schedules for hotwater (2hrs midday) and a schedule to have room temp around 21 during the day and 19 at night. when i go into melpump, device settings it is showing "constant flow" instaed of "AA! the hoter is set at the lowest and the heating set to the highest? 

i was expecting it to mirror what had been set on FTC5, or have o got that all wrong?

@boycey are you absolutely certain that Havenwise control has been relinquished..?

It sounds very like the settings that it uses

Well I asked them about it and they said to make dinner changes to get back to my old settings. I thought was it. But I shall ask if they have removed control. Thanks

You can remove control directly via the settings options in the Havenwise app.

@sheriff-fatman thanks just found that, so yes havenwise was still active. Thanks

Thanks everyone for the help, Havenwise now diasbled. question re schedules, if i want to run schedules for hot water and slight temp variations throughout the day, if i use melcloud or melpump, do i need to set anything via the FTC5, ie if there are schedules on there do they need to be removed and the mode left in "run" or "scheduled". i'm basically thinking of avoiding conflicts between the FTC5, melpump and melpump.

This might be one for @f1p to chip in on for confirmation about the CN105 dongle but my understanding is as follows:

• With standard operation as Mitsi intended, the scheduling in Melcloud and the scheduling on the in house display are NOT integrated. It is possible to make changes to schedules on the in house display that conflict with the Melcloud scheduling, and I believe if that occurs then the in house settings take precedence. It is also certainly true that there are some types of scheduling that can only be done in house, and any scheduling done via Melcloud requires that the Internet connection be up when Melcloud needs to send the trigger.
• With Melpump being used in the mode that uses the Mitsubishi API for data, all the details of the previous point still apply even though more information is exposed.
• With Melpump being used in conjunction with the CN105 dongle - and here is where I'd need @f1p's confirmation - I believe there is still a disconnect with the in house schedules and so there remains a potential for conflicts between schedules. If this arises, I am less sure that the in house schedule will always take precedence, and I think Melpump still needs your Internet connection to be up to talk real time with the dongle when a trigger occurs.
• Given the CN105 dongle can also be managed locally (e.g. via Home Assistant), this would remove the issue of the Internet connection being down when a trigger needs to be sent, but if my previous point is correct - that the CN105 dongle doesn't actually store schedule information - this would mean any schedules created in Home Assistant would be independent of the in house schedules.
• I don't believe any conflicts arising from any of these scenarios would cause any harm; just produce unpredictable and confusing results.

Does that help at all?

@majordennisbloodnok hi. This makes me think that I'm probably best to set my schedules up using the ftc5 and just use melpump to monitor, and then just use summer eco or holiday mode on melpump as required reducing any internet reliability. Is that a fair comment?

@majordennisbloodnok @boycey 

So to clarify, I don't belive that @boycey is using the dedicated MELPump CN105 Adapter and only using MELCloud integration - is that correct?

Regarding schedule conflicts, the main issue is that internet time is used for triggering actions from the internet services like MELCloud & MELPump, where on the main controller it will be using local time.
And they are almost certainly not aligned exactly which results in this whichever command was received last.

The final part is how the MELPump CN105 Adapter works, because enabling MELPump App Control Mode (also known as Server Control Mode) will ignore all FTC schedules, thus preventing scheduling conflicts

set my schedules up using the ftc5

I would say Yes, to this. What users find though is there are not enough change points permitted within the FTC for tariffs like Octopus Cosy and this is why there is a use case for internet controlled schedules.
