Takie, Thanks for linking me up - the missing feedback loop once target temparatures are reached is really disappointing then. Many people will look at that more closely now that we all save hard on energy .. and Viessmann kindly added the heater temp to the app dashboard, which makes the useless heating apparent. For my specific case I even experience massive heating despite the heating being switched off at the heater (only warm water active) .. this is even worse resp. alerting. Hence it might be a different issue with valves towards warm water heating pipes. Anyway, will report back - thanks for your input!! Best, Stephan
