SONOFF SNZB-04PR2 ZigBee Smart Door/Window Sensor, 4-Pack

Product detailed description

The SONOFF SNZB-04PR2 is a window and door sensor that uses Zigbee 3.0 communication, allowing you to monitor the status of secured areas in real time via the app. The device detects when doors or windows are opened or closed, alerts you to any attempt to remove the sensor, and sends real-time notifications, allowing you to respond quickly to any change in status. It is powered by two AAA batteries and provides up to 3 years of operation without the need for frequent battery replacement. The housing is made of UV-resistant materials, and the device has passed a 1-meter drop test as well as thermal shock tests. The package contains 4 pieces.

Continuous Monitoring and Instant Alerts The sensor allows you to monitor doors and windows directly from the eWeLink app. Alerts about doors or windows being opened or closed appear immediately, giving you full control over your secured rooms. In addition, the tamper detection feature alerts you to any attempt to tamper with the sensor, thereby enhancing the security of the entire system.

Smart Scenes for Security and Savings The SNZB-04PR2 can work with other smart home devices to create automations tailored to your daily needs. The sensor can trigger security scenarios when it detects an open door or window, working in conjunction with a Zigbee gateway, security cameras, and other devices. It also works great in energy-saving scenarios, such as automatically turning off the thermostat when a window is open or turning off the lights when a door is closed.

Flexible Installation in Various Locations Thanks to the removable magnet and the option to mount it in either a horizontal or vertical position, the device can be easily adapted to many types of doors and windows. The sensor has a detection range of up to 30 mm when mounted horizontally and up to 15 mm when mounted vertically, which makes installation easier even in less standard locations. The design works well not only on doors and windows, but also on refrigerators, first-aid kits, pet cages, and safes.

Wide compatibility with smart home ecosystems The device works with the eWeLink, Home Assistant, and MQTT apps, as well as the iHost, Amazon Alexa, and Apple Home platforms via Matter Bridge. Thanks to support for the Zigbee 3.0 standard, the device can be integrated with many popular gateways and home automation systems. Users can also check the sensor’s status using voice commands in compatible systems. Technical specifications:
