[APP][PRO] VThermo

Thanks @balmli , that’s helpul. So If I understand correctly, a flow like this should turn on the Fibaro relay that demands heat from my boiler:

…which compares the current measured temperature from the devices in the zone and compares iit with the radiator TRV set temperature…

…provided I have:

  1. The option for Heaters ticked in the VThermo device settings:

  2. The Fibaro switch/relay in the same zone as the VThermo device

  3. The Fibaro switch/relay designated as “Heater” under “What’s plugged in?” in the phone version of the device settings (which doesn’t seem to be available in the web version of the device settings)… so that VThermo knows it’s a heater

Is that right?

If so, is there any advantage for using VThermo vs a flow like this?:

If understand correctly from reading above, I can tick the option in the VThermo device settings so that the heating is turned off if a window open (contact alarm) in the same zone is active and back on again if the window is closed, without other flows, but in my case the “turning off” would presumably just turn off the boiler heat demand, rather than the turn off / reduce the radiator set temperature - is that right?
