The SONOFF DW2 Wi-Fi Wireless Door/Window Sensor is designed to monitor the status of doors and windows within a home environment. It connects to a smartphone app via Bluetooth for pairing and Wi-Fi for ongoing control, thus eliminating the need for a separate gateway. Users can promptly receive push notifications if the sensor detects an opened door or window, providing real-time updates on the security status of their residence. The sensor is versatile, suitable for various locations such as sliding doors, windows, or hinged doors, and boasts a tool-free setup facilitated by the 3M adhesive on its base.
