@Wayne-TP Thanks for the reply. That's how I thought it would work. But the two ke100 thermostats connected to the tapo t315 sensor work differently. They turn on and off randomly. Even the data...

Hello I have a room with two radiators. Each radiator has a ke100 installed. I also have a room temperature sensor tapo t315. The question is ... can one t315 control the two ke100 ?
