Lafaer LWR01 Matter Presence Sensor

The Lafaer LWR01 is a battery-powered mmWave presence sensor that connects over Matter via Thread, making it usable with any Matter controller and Thread border router across Apple Home, Amazon Alexa, Google Home, SmartThings, Home Assistant, and Homey. Unlike PIR sensors, the mmWave radar detects subtle movement and stillness up to 3.5 m for a stationary person and 6 m for general movement — so it keeps the lights on when you’re reading on the sofa, not just when you walk by. An IPX3 rating allows use in bathrooms and other humid spots, and the wire-free design means it can go almost anywhere.
