In my living room I have 3 Vicare radiator thermostats + climate sensor. The measure from the climate sensor is correct, the thermostats are wildly incorrect. Causing the combined temperature to be off by about 1°C for the moment. For heaven's sake why is it not user adjustable to have a) either an adjustable offset b)let the climate sensor overrule for 100%. Once again: just look at how Tado does it. Contrary to Viessmann they actually have some software development know-how.
