Hello everyone! I need to switch my boiler on at the specified time but only in case the house is not running on a backup battery. I have a dual power transfer switch, not smart. And a battery that powers the house during power outages with a smart plug. The problem is that when the battery is off then the plug is offline too and I can’t just add a precondition current=0, which means that the house is not powered by the battery. I have 1 more “signal” plug that is connected directly to the grid so it is offline during power outages and off and without any load connected during normal hours and several spare plugs. Could you advise me any solution for this case please?
