Overview
You have no idea if burglars broke into your house in your absence? Have you ever imagined that your house lights up immediately when you open the door? Or you want your bedroom light to turn off automatically once you enter the living room?
Any of your ideas will come true with SONOFF DW2-Wi-Fi wireless door/window sensor. DW2-Wi-Fi comes in two pieces, the transmitter fits on the door or window and the magnetic switch attaches to the frame. It can help secure your door or window so you know if your home is safe wherever you are. The sensor will trigger an alarm on your smartphone to remind you of the presence of an intruder when the door or window is opened. Connect the SONOFF wireless IP camera and you can see who the intruder is on the sensor page of the APP (App). Regardless of which door or window is open or closed, you can check the real-time open and close status on the eWeLink APP.
The real-time battery level display and low battery reminder ensure you know clearly how long the sensor can operate and when you need to replace the batteries. With simple peel-and-stick installation, it is easy to attach to door frames and window sills.
* Battery life is up to 3 months if the door/window is opened or closed three times a day.
