5 Home Assistant Presence Sensors That Catch Stillness (2026)
Five 24 GHz mmWave presence sensors ranked for Home Assistant users — covering Wi-Fi, Zigbee, and Matter over Thread, with honest notes on range, false-trigger risk, and power trade-offs.
Smart presence sensors use millimeter-wave radar to detect whether a person is in a room, including someone sitting still — something standard motion sensors cannot do. They integrate with platforms like Home Assistant to automate lighting, climate, and security routines. When comparing, look at detection range and multi-zone support, platform compatibility, and whether the device is wired or battery powered.
