I have a short question like in thema of this post. Is there any chance to triger e.g. Sonoff Basic with AC or relay powered by AC on? I'm almost sure that won't work with High Voltagebut maybe with relay connected to some programming port?
Let's explain the wanted situation:
Sonoff Basic is connected to my Wifi and to AC. The same sonof is connected with cable to the pir sensor (not Itead pir sensor). This sensor is sending AC voltage and trigering this sonof ON. Or via relay with close the circuit. Than via scene another Sonoff devices are switched on.
