SONOFF SNZB-04PR2 ZigBee Smart Door/Window Sensor

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 properties in real time via the app. Its slim design, just 13.5 mm thick, makes for discreet installation, and a communication range of up to 100 m in open spaces ensures stable operation throughout your home. The device detects when doors and windows are opened or closed, alerts you to any attempts to remove the sensor, and sends real-time notifications, allowing you to respond quickly to any changes in status.

Continuous Monitoring and Instant Alerts The sensor allows you to monitor doors and windows directly from the eWeLink app. Information on whether doors or windows are open or closed is displayed 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 left open or turning off the lights when a door is closed.

Flexible Installation and Broad Compatibility Thanks to its 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 supports a detection range of up to 30 mm when mounted horizontally and up to 15 mm when mounted vertically, making installation easier even in less-than-standard locations. The design is suitable not only for doors and windows, but also for refrigerators, first-aid kits, pet cages, and safes. The device works with the eWeLink, Home Assistant, MQTT, and iHost apps, as well as the 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, and the sensor’s status can also be checked in compatible systems using voice commands. Long battery life and durable construction
The device is powered by two AAA batteries and provides up to 3 years of operation without the need for frequent battery replacement. The case is made of UV-resistant materials, and the device has passed a 1-meter drop test as well as thermal shock tests.
