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.

The color /code of wire maybe correct but people may also install incorrectly.
Best check with a multi meter.
