Sonoff SNZB-04P Zigbee Door/Window Sensor - Enhanced Security with Tamper Alert
The Sonoff SNZB-04P is an advanced Zigbee 3.0 door and window sensor, designed to enhance the security of your smart home. The device detects the open and closed status of doors and windows, sending immediate notifications to your smartphone via the eWeLink app. Thanks to the built-in tamper protection feature, the device instantly alerts you if anyone attempts to remove or tamper with it.
Compared to its predecessor, the SNZB-04P features improved design and performance, including a longer battery life of up to 5 years, and a maximum installation gap of 20mm between the sensor and the magnet. Its small size and multiple installation options make it suitable for various applications, from home security to energy-saving automation systems.
The sensor integrates seamlessly with Zigbee 3.0 hubs such as Sonoff NSPanel Pro, iHost, ZBBridge Pro, ZBDongle-E, and ZBDongle-P, as well as platforms like Home Assistant, SmartThings, and Amazon Alexa (with a built-in Zigbee hub).
