The PIR sensor
If you have Lightwave Dimmers or Plugin sockets installed, adding a simple wireless Lightwave PIR sensor can automatically turn on a landing or bedroom light at night if movement is detected.
Useful at night time
If the kids get up to use the bathroom, there path will be safely lit. Even better, the dimmer will automatically turn off again once they are safely back in bed, so the lights don’t stay on for the rest of the night!
