Mains comes in on L and N, and O carries the switched active out to the appliance while the relay reports its live power draw and energy use in the app. A wall switch on SW keeps working alongside the app. Up to 8 A, so check the appliance's rating; a pump or other motor needs an RC snubber across the load.
