Hi
I have just set up heatit zwater to control my underfloor heating valves, i have three zones, and in each zone, i have one fibaro motionsensor to see the temperature. the vthermo see`s the temperature from the motion sensor. How do i get the vthermo to swich on and off the relays in the heatit zwater when the target temperature is reached?

Hi
just found it out myself 🙂 I had to set the relay as a heating element in settings. This virtual Vthermo app is absolutly fantastic, it now turns on/off the relay at desired temperature. Thanks for a fantastic app
