Aprašymas

SONOFF SNZB-04PR2 Window and Door Sensor, 4-Pack

The SONOFF SNZB-04PR2 is a door and window sensor that uses Zigbee 3.0 communication, allowing you to monitor the status of secured items in real time via the app. The device detects when a door or window is 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. Powered by two AAA batteries, it 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 and thermal shock tests. The package contains 4 units.

Constant Monitoring and Instant Notifications

The sensor allows you to monitor doors and windows directly from the eWeLink app. Notifications about when a door or window is opened or closed appear immediately, giving you full control over the secured rooms. Additionally, the Tamper Detection feature alerts you to any attempt to tamper with the sensor, 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 scenes when it detects a door or window opening, working in conjunction with a Zigbee gateway and security cameras, among other devices. It also works well 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 in Various Locations

Thanks to its detachable magnet and the ability to mount it horizontally or vertically, 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, which makes installation easier even in less standard locations. The design works well not only on doors and windows, but also on refrigerators, medicine cabinets, pet cages, and safes.

Wide compatibility with smart home ecosystems

The device works with the eWeLink app, Home Assistant, MQTT, iHost, and the Amazon Alexa and Apple Home platforms via Matter Bridge. Thanks to its support for Zigbee 3.0, it can be integrated with many popular gateways and home automation systems. Additionally, users can check the sensor’s status using voice commands in compatible systems.
