Hi, anyone know which wire in the photo attachment is L and N? One of it is solid black and another one has white strip on it. I don't know if my wiring installation is correct or not cos the device seems like no power.

no point cause he needs to turn on and off a 12v DC device
what he needs is a Sonoff S20 smart socket
*
Sonoff S20 smart see socket can control any device or plug attach to it?
