@ Jensk; I think so , they work fine these thermostats , when I set a setpoint temperature, the temperature is there exact! ( measured with a seperate device offcourse). But the downside is , for the thermostat to respond , it takes time ( wake up intervall?) and than to actually open or close the valve, it takes ages. But in a scene to have the room at a specific temperature, starting about 1 hour before works super.
