The Bosch UFH Thermostat (https://www.bosch-smarthome.com/de/de/service/hilfe/hilfe-zum-produkt/hilfe-zum-raumthermostat-fussbodenheizung/) are working flawless.
I would just love an attribute/ sensor that shows the current wanted Temperature.
Reason: By detecting a change in the wanted Temperature, I could switch OFF heating and turn ON the AC. And vice versa. Or by increasing the temp add AC heating.
The options are endless
