Doors and windows, like entrances and exits, are the weakest points in your home. An unsecured door or window is like an obvious "WELCOME" signal, for a burglar, so door/window sensors are also known as "entry sensor". As one of the most popular home security devices, the DW2-RF wireless door/window sensor is smart enough to let you know if your door or window is open, and can not only send you alert notifications, but also let you know when the entry point is opened, making sure your home is safe.

More importantly, the sensor allows you to add a security camera or an old smartphone to see who enters your home, providing you with more details and notes about the unwanted guest. You can sync the door/window opening status with the app, giving you peace of mind when you're not home. Checking historical records can go back to the last 3 months, which can help you look back and check the status of your home at that time. Lights are activated in action. You can set the link in the smart scene of the eWeLink app to connect the sensor and your light so that you can open the door to turn the hallway light on and off. The SONOFF Bridge is required to make this linkage possible.This "device sharing" feature serves to let more members of your family know that your home is safe. After sharing the sensor, all shared users will be alerted to the status when someone opens the door. The sensor is installed with 3M adhesive and is easy to move and remove. It can work perfectly upside down and sideways, as long as the magnet is within 5 mm of the sensor, which does not change the location of the sensor. It is battery operated and has a low power consumption which ensures that the battery life can last up to 2 years.
