@derek-m - still trying to make sense of that climate.py code. One observation: the DHW tank actual temperature isn't defined in that climate.py code,...
This heat delivered by heat pumps thing is a bit of an enigma. I am off mains gas, and used to have oil CH. In a typical heating season, I might use 1...
@filipe - although much of the 'how to' has ended up ad hoc in this thread, I am going to try and write it up in a more structured way in my Beginner'...

I doubt we will get -12C in the near future! In fact, I think we are unlikely to get much below zero during this week, if that. I will watch the local...
@derek-m - at the moment (13:24) the wired controller outdoor temp shows 12 degrees, maybe it was 11 degrees. At 1308 (one of the random not on the ...
I think this has to be the case, given neither of us has found anything in the code that requests the 04/04 message data. The odd thing is the random ...
