Sonoff RF Wireless Door/Window Sensor DW2-RF

Sonoff RF Wireless Door/Window Sensor DW2-RF

The SONOFF DW2-RF is a wireless door and window sensor that communicates on 433MHz RF. A magnet and the main unit detect when a door or window opens or closes. Paired with a SONOFF 433MHz RF Bridge, it sends alerts to the eWeLink app and can trigger smart scenes, for example turning on the hallway light when the door opens.

Open and close detection: The sensor reports every time the magnet moves away from or back to the main unit, so you know when an entrance is opened.

Alerts and scenes through the RF Bridge: Through a SONOFF RF Bridge, the DW2-RF brings open/close notifications into the eWeLink app and can trigger lights, alarms or other SONOFF devices in smart scenes.

Long RF range: It has a maximum wireless transmission distance of 50 m, which gives flexibility in where you place the RF Bridge.

Battery powered, easy to fit: It runs on 2 x AAA batteries (3V DC) with a low-power design, and it attaches with adhesive, so no wiring or drilling is needed.

Who it's for / Works with

SONOFF 433MHz RF Bridge (RF BridgeR2) and the eWeLink app.

Good to know

• The DW2-RF needs a SONOFF 433MHz RF Bridge to work with the eWeLink app.
• The 50 m range is the maximum transmission distance; walls and obstacles reduce it.
• Uses 2 x AAA 1.5V batteries.
