Summary Have you ever had the fantasy that as soon as you open the door, your house lights up? Or would you prefer that the light in your bedroom turn off on its own when you enter the living room? With the SONOFF DW2-Wi-Fi wireless door/window sensor, your ideas can come true. The DW2-Wi-Fi is a two-piece device; the magnetic switch is attached to the frame, and the transmitter is designed to fit onto windows or doors. No matter where you are, it can assist in securing your window or door to let you know whether your home is secure. When the window or door is opened, the sensor will send an alert to your smartphone alerting you to an intruder. When you connect the SONOFF Camera, the intruder's identity will be visible on the APP's sensor page. Whatever
