Adding cooling support for evohome

[fuecy]

Hi, i think i have a new feature request. I have an evohome setup with a heatpump that supports heating and cooling. Basically my heatpump is controlled by 2 BRD91T1004. One for the normal demand, and one for sending that demand to the heating input or to the cooling input. From my evohome, i can set the system modus in cooling or heating. this is the support article of my setup.

When i switch from heat to cold, i see the following errors.

My feature request will be, can we make it support cooling?

Hello - I have make the necessary fix - it will be included in the next version of the library (ramses_rf).

Getting it into (ramses_cc) will take a little longer, and I will need testers.

Please keep an eye out here.

Hi Thanks for looking in to this. I am happy to do some extensive debugging and diving in all scenarios. But I think like most of us, I have private and work commitments and I just can’t guarantee same day reply and the weekend might be full. But I am happy if I can help in any way.
I have attached another log file. This file the system is on cooling from the beginning.
packet.log

I have some observations till now.

1. It looks like that 13:040441 is the relay that switches between heating and cooling. However in home assistant it never switches from state. Its only off.

2a. On the moment the system is in cooling, there is some disagreement over the set temperature. (the graph is of 04:197927 included in the log. Purple is the set temperature)

2b. It might be related. The zones can be heat only, cold only and heat/cold. When the zone is on heat only, evohome shows the zone as off, however the radiator valve goes completely open and on 100% demand. So I have al my zones on, but with a set temperature of 30. (and so its switching between 5 (off?) and 30.

3. the logs when switching from cold to heat and back
