Description
The SONOFF DW2-RF is a wireless door and window sensor that communicates on 433MHz RF. Its magnetic contact detects when a door or window is opened or closed and sends an instant signal to connected SONOFF devices.
Paired with the SONOFF RF Bridge, it brings real-time alerts and smart automation to the eWeLink app, for example turning on lights or sounding an alarm when a door opens. It runs on 2 AAA batteries, has an operating range of up to 50 m, and installs quickly with screws or adhesive tape.
Note: a SONOFF 433MHz RF Bridge is required to use it with the eWeLink app (see "Works With" below).
