Quick verdict
The Hue motion sensor is the boring reliable choice — it detects motion, it tells your lights, it doesn't overthink it. Zigbee pairing through a Hue Bridge or direct coordinator is painless. It won't do mmWave-style presence detection, but for motion-triggered automations, it's hard to fault.
Standout: Easy, low-drama Zigbee motion sensing that fits mainstream homes better than most enthusiast mmWave gear.
