Lafaer Wireless Human Presence Sensor

The LWR01 is a mmWave presence sensor that notices real people, not just motion. It reads micro-movements and stillness at close range, up to 3.5 m when you’re seated and up to 6 m when you’re moving, so the lights stay on while you binge and only shut off when the room is truly empty. An ambient light sensor rides shotgun to keep lamps from flipping on when daylight is already doing the job, which trims energy use without extra taps or scenes.

It’s built for everyday spaces, bathrooms included, with IPX3 splash protection. Power it on batteries for more than a year of cable-free placement, or plug in Type-C DC for continuous duty; either way, you get the same quick presence detection and light-aware automations. Thanks to Matter over Thread, it joins your preferred platform with no new hub, working with Apple Home, Amazon Alexa, Google Home, SmartThings, and Home Assistant.
