Hello everyone,

I have a question about shelly 1, didn’t use it so far. Can I connect one shelly device, and depending if that shelly is currently getting some power then turn on/off another shelly?

First shelly will be connected to device, and if that device shares power through to shelly, then second shelly should turn on another device.

Is that possible with that? or should I use something else?

    Probably would be best to give a description of what you are actually trying to do instead of how you are thinking of doing it. There are always multiple ways to do something.

    To answer your question, sure, with relays, etc you can accomplish what you wrote…just not sure that’s what you really want.

      I will try to do it best I can (english not my first language)

      I have an underfloor heating with heat pump. I have to cabinets for underfloor heating, from where the tubes go around, and all the thermostats for rooms are connected (one for each floor of the house).

      The pump that pumps the water through tubes is currently not connected with those cabinets and I need to connect it somehow. Because if all the thermostats are turned off then the pump doesn’t need to work.

      In the cabinet where all the thermostats for the floor are connected I can know if all the thermostats are turned off (by turned off, I mean that the temperature is high enough and it doesn’t need to heat currently) . So my idea was to connect one shelly to each of those cabinets, and if there is no thermostats that requires heating currently, then the shelly that is connected with the pump should turn the pump off.

      Hope you could understand it :)

      So, by my idea, I would have 3 shelly devices, and if one of the two in cabinets is getting signal, then the 3rd one should be powered on and pump should work.
