SwitchBot mmWave Presence Sensor - The Still Signal

SwitchBot · $

Vidar treats the SwitchBot mmWave Presence Sensor as a local occupancy signal, not a decorative gadget. It combines mmWave radar, a light sensor, and PIR to detect stationary and moving people. SwitchBot lists a 120 degree field, up to 8 m for moving people and 5 m for stationary people. The magnetic base supports flat placement and wall mounting, with an adjustable detection angle. Two AAA batteries can run for up to two years. The 54 x 54 x 28 mm, 38 g body carries IP55 protection and works with SwitchBot devices without a hub for local automations. Apple Home support requires a SwitchBot Matter Hub, while the page also lists Home Assistant, Alexa, and Google Home. Check current price, battery terms, platform compatibility, and the one-year warranty before buying.
