Is it possible to connect a shelly (on 220V) to a pir (OMRON) sensor , which is powered seperately with 12V . The pir sensor has an output of 2 wires that are shorted or not.
I want to use the shelly for this to see if the Omron sensor has been switched on and off ...and use this furtheron in my domotics controller.
I possible...how would i need to wire this?
Thanks in advance.
