I was peviously asking about this for a bathroom fan, but I've now decided to use a PIR for that purpose.
However, because of the layout in the apartment, the problem is with a second bedroom light, which although has a permanent live to it, it doesn't have a switch-wire. (Actually I've made the switch-wire a permanent live to feed the extractor fan in the en-suite ... too much detail).
Which means that one of the bedroom lights needs to be switched somehow with the other (normal) bedroom light. Don't really want to hack the ceiling out to get a switch wire across the room (flat roof).
I'm thinking is there a simple way to trigger the light with a transmitter/receiver when the other normally-switched light becomes energised?
A bit like wireless interlinked smoke alarms if you know what I mean.
Looked at the Quinetic site, but all transmitters seem to depend on the movement of a switch. Don't want to change the switches. TIA
