Product Description
The SONOFF SNZB-04P is an upgraded Zigbee 3.0-based door and window sensor, delivering enhanced performance, robust security, and seamless automation for your smart home. Whether you're looking to automate lighting, receive instant intrusion alerts, or set customized smart scenes, this compact sensor is your home's first line of defense and convenience.
Built with tamper detection, you’ll be instantly notified via the eWeLink app if someone attempts to remove or tamper with the sensor. And thanks to the customizable "door open duration" alerts, you’ll be alerted if a door is left open longer than usual — perfect for energy saving and security.
With ultra-low power consumption, the CR2477 battery ensures a 5-year battery life, giving you long-lasting, worry-free operation. Even in the event of internet loss, SNZB-04P leverages Zigbee local scenes, so automation continues to function reliably.
The sensor integrates effortlessly with SONOFF Zigbee hubs (NSPanel Pro, ZB Bridge Pro, iHost, ZBDongle-E/P) as well as third-party platforms like Home Assistant (ZHA / Zigbee2MQTT), Alexa, Google Home, SmartThings, Alice, and IFTTT.
Its 20mm detection range, wide temperature tolerance (-10°C to 60°C), and tamper-proof build make it suitable for installation on any door, window, cabinet, or drawer, turning them all into smart entry points for your home.
