Last 2 years my home automation was working flawlessly with 7 thermostats. And now the heating season started and all of a sudden, thermostats do not report correctly.
The are overheating by a lot, I have set 22°C and they are reaching 24°C being still wide open.
The valve position is wrong all the time, sometimes it’s stuck always on 25% and sometimes on 0% even though in reality it’s wide open or completely shut down.
