Nobody Lives in That Room

The light bill is not a participation trophy.

The problem

Lights blazing in empty rooms all day. The laundry. The pantry. The downstairs loo at 2pm in summer.

What it does

When a room has had no motion for 8 minutes, the lights go off. If anyone's actually in there, motion keeps them on. Simple. Ruthless.

You'll need

Motion sensor per room
Smart lights or switches

The payoff

Trims phantom lighting load — typically a few dollars a week per room.
