Thank you Bernard
How do I find out which of the cables is the lamp cable please.
I've no idea what a multi meter is.
You are correct - the lamp is away from the sensor
Recently bought the Kanlux motion sensor for an outdoor light.
The only problem is that when it’s switched on it stays on ! The switch for the sensor is inside the house.
Coming out of the wall where the sensor is mounted are two circuit cables. Each cable has a brown and blue cable...
