SONOFF SNZB-04PR2 Window and Door Open Sensor

<h3>SONOFF SNZB-04PR2 Window and Door Sensor</h3> <p>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.
Its slim design, just 13.5 mm thick, facilitates discreet installation, and a communication range of up to 100 m in open space ensures stable operation in various parts of the 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 status changes.</p> <p> <img alt="Sonoff door and window sensor mounted on a balcony door frame" border="0" src="https://assets.innpro.pl/22970/30087/2.jpg"/> </p><h3>Constant Monitoring and Instant Notifications</h3> <p>The sensor allows you to monitor doors and windows directly from the eWeLink app.

Additionally, the Tamper Detection feature alerts you to any attempt to tamper with the sensor, enhancing the security of the entire system.</p> <p> <img alt="A boy climbing out of his crib, next to a smartphone with notifications enabled" border="0" src="https://assets.innpro.pl/22970/30087/4.jpg"/> </p><h3>Smart Scenes for Security and Savings</h3> <p>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.</p> <p> <img alt="Camera detecting a burglar entering through the balcony door" border="0" src="https://assets.innpro.pl/22970/30087/3.jpg"/> </p><h3>Flexible Installation and Broad Compatibility</h3> <p>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.
