Rörelsesensor

Battery life is genuinely impressive—I've had it tucked behind the curtain for three weeks and the app still shows full power. Setup took two minutes and now the hallway lights just come on before I even reach for the switch.

Mounted it in the hallway near the stairs and now the lights flick on before I even reach the bottom step. The battery-powered setup meant I didn’t have to worry about wiring, and it sticks anywhere I’ve tried so far.

Setup took me about five minutes and it’s been rock solid since—lights flick on the second I walk into the hallway. Only minor gripe is the app could be a tad more intuitive when adjusting sensitivity, but once it’s set, it just works.
