SONOFF SNZB-03P Zigbee Motion Detector - PIR 110° - Light Sensor - 3 years

Automatically turn on a hallway light when you pass, turn it off as soon as you leave, and never trigger it in broad daylight: the SNZB-03P does all this with a 5-second response, a 3-year battery life on a single battery, and an integrated light sensor for truly smart automations.

Key features

⚡ Ultra-fast recovery in 5 seconds

The minimum rearming time is 5 seconds - compared to 30 to 60 seconds for conventional detectors. The light turns off quickly after you pass, without wasting unnecessary energy.

☀️ Integrated ambient light sensor

Conditions triggering to ambient light: configure automation to only turn on the light if the room is dark. In broad daylight, no unnecessary triggering.

🔋 3 years of battery life - CR2477 battery

The long-life CR2477 coin cell battery provides over 3 years of battery life under normal conditions of use (50 triggers per day at 25°C). Zero maintenance for years.

🧲 Adjustable magnetic mount

The sensor attaches to its magnetic base with a flexible ball joint allowing precise orientation of the detection field in any direction. Wall mounting with 3M adhesive or screws.

⚠️ A compatible Zigbee hub is required for pairing and creating automatic scenes. For advanced settings (recovery time, brightness threshold), it is preferable to use Zigbee2MQTT or ZHA under Home Assistant. With Somfy TaHoma Switch, only default values are available, with no possibility of configuration.

💡 Our recommendation: Install the SNZB-03P at a height of 2 to 2.5 m, oriented at 30-40° relative to the target area for optimal coverage. Under Home Assistant, create an automation with a double condition: motion detected AND brightness below the defined threshold - the light will never turn on in broad daylight. If you need to detect stationary presence (person sitting, sleeping), consider the SONOFF SNZB-06P radar sensor which uses mmWave technology.
