AHH I think you hit the nail on the head.
It also operates a extractor.
It's only a single switch to a bathroom
I'm going to test the cables to help explain what's live etc so hopefully you can help. I was just expecting two wires but then found this which confused me.
Evening everyone
Hopefully someone can help
Trying to replace a light switch with a room pir. Stuck on the wiring
Which terminals should I remove and connect to the PIR please.
Thanks in advance
I have attached pics to help
