DW2 Wi-Fi Wireless Door/Window Sensor - OPEN_BOX

The SONOFF DW2 WiFi Wireless Door/Window Sensor is a compact smart security sensor designed to monitor the open or closed status of doors, windows, cabinets, drawers, and gates. It connects directly to your 2.4GHz Wi-Fi network through the eWeLink app, eliminating the need for a separate gateway or hub. When the sensor detects that a door or window has been opened or closed, it instantly sends a notification to your smartphone, helping you monitor your home, office, or business remotely. The DW2 can also be linked with other SONOFF smart devices to create automation scenes, such as turning lights on automatically when a door opens or triggering alarms when unexpected movement is detected. Its two-piece magnetic design allows for quick peel-and-stick installation on most door and window frames. The device is battery powered, offering simple wireless operation with low power consumption and battery-level monitoring directly in the app.
