Sonoff SNZB-06P Presence Sensor

The Sonoff SNZB-06P is an advanced Zigbee presence sensor using 5.8GHz microwave radar technology to detect human presence even when stationary. Unlike PIR motion sensors that only detect movement, this sensor can identify occupied rooms where people are sitting still, reading, or sleeping. This makes it ideal for lighting automation that shouldn't turn off while a room is actually occupied.

The radar detection works through materials like blankets, making it suitable for bedroom presence detection. Detection range is adjustable from 0 to 6 meters with sensitivity tuning to prevent false triggers. The sensor also includes a light sensor for ambient brightness detection, enabling automations that consider both presence and lighting conditions.

The SNZB-06P requires a Zigbee 3.0 hub to operate, compatible with Sonoff's ecosystem as well as SmartThings and Home Assistant. Through these platforms, it integrates with Amazon Alexa and Google Home for advanced automation scenarios. Home Assistant users particularly value this sensor for truly responsive room-based automations that understand the difference between an empty room and one with a stationary occupant.
