SONOFF SNZB-03P Zigbee 3.0 Motion Sensor

Never manually turn on the light again – the SONOFF SNZB-03P handles it for you.

Are you tired of fumbling in the dark for a light switch in the evening? Or do you simply want to know when there's movement in your hallway, garage, or children's room? The SONOFF SNZB-03P Zigbee 3.0 motion sensor offers a smart, affordable solution for any room in your home.

🚀 Real-time detection, long lifespan

Thanks to advanced PIR infrared technology, the SNZB-03P detects movement in real-time – as soon as someone enters its field of view, the sensor registers it instantly. With a detection range of 6 meters and a detection angle of 110°, the sensor monitors a wide area without blind spots. The minimum detection duration can be set to at least 5 seconds – useful for quick lighting scenes.

In addition to motion, the SNZB-03P also features a built-in light sensor (Lux), allowing you to set up automations that only react when the room is dark enough. This way, your light only turns on with movement AND if the ambient light is already low.

The sensor operates on a CR2477 coin cell battery (3V), which is already included in the package. Simply pull out the insulation strip, and the sensor is immediately ready for use. The battery lasts for more than 3 years.

📐 Installation & mounting

The SNZB-03P comes with a magnetic base, allowing you to easily rotate and aim the sensor without tools. Mount the sensor at a height of up to 2 meters for optimal detection. The signal range indoors is up to 30 meters to the Zigbee hub.

🔗 Broadly compatible with popular smart home platforms

The SNZB-03P operates via the Zigbee 3.0 protocol (IEEE 802.15.4) and is compatible with almost all common smart home systems:

• SONOFF's own hubs: ZBBridge, ZBBridge-P, NSPanel Pro, AIBridge, ZBDongle-P, ZBDongle-E
• Amazon: Echo Plus 2nd Gen, Echo Show 2nd Gen, Echo 4th Gen
• SmartThings: SmartThings Hub V3, AeoTec Smart Home Hub V3
• Home Assistant: via Zigbee2MQTT or ZHA with Zigbee Dongle
• Apple Home, Google Home, Alexa and IFTTT
• All other gateways that support Zigbee 3.0

🏠 Local scenes – even without internet

The SNZB-03P supports local Zigbee scenes. Your automations will continue to work even if your WiFi or internet connection goes down – as long as the Zigbee hub and devices have power.

💡 Example automation

Imagine: it's evening, and you walk into the hallway. The light sensor detects that it's dark, AND the PIR sensor detects your movement. The SNZB-03P immediately sends a signal to the hub and automatically switches on the hallway light. After 5 seconds without movement, the light turns off by itself. At night, you activate a security scene: upon detection, your smartphone receives a push notification, AND your security camera starts recording.

📦 Technical Specifications

⚠️ Important Note

The SNZB-03P is only suitable for indoor use and should be mounted at a height of up to 2 meters for optimal detection performance. For outdoor use or damp environments, we recommend a weather-resistant sensor.
