The Sonoff DW2 sensor can help secure your doors, windows, fridges, freezers, caravan etc or anything that has a door that opens and closes. The sensor can trigger an alarm to your smartphone to inform you of an intruder when the door or window is opened, when a door has not been closed for a certain period or it can change the status of other smart devices based on the door contact status.

Connect a Smart Wireless Camera and you can view who the intruder is on the sensor page of the APP. Whenever your door or window is opened or closed, you can check the real-time opening and closing status. As with any Ewelink Smart device the Door Contact can be integrated with Alex, Google Home and other  personal voice assistants.

This door contact has direct WIFI Built-in and does NOT REQUIRE a RF or Zigbee bridge for communication to your WIFI network

** Batteries Not Included : Requires 2 x AAA Batteries
