After three weeks of testing I don’t know how to move on.
At the moment I only use the manu mode at the thermostat. The Pi is able to receive all updates, thats fine. But I’m not able at all to trigger any changes at the Pi.
When I change the temperature in pimatic, the item turns grey and after several seconds, it changes back to white (black in default theme) and has the old temperature again. At the termostat nothing happened.
The thermostat is in manual mode and child lock is disabled. Do you have any ideas?
Same behavior with the other buttons (auto, comfy, eco, boost).
