SONOFF DW2-RF User Manual V1.1
RF Wireless Door/Window Sensor
Introduction
The SONOFF DW2-RF is a low-energy wireless door/window sensor designed to detect the opening and closing status of doors and windows. It communicates via the 433MHz RF protocol and requires a SONOFF 433MHz RF Bridge for intelligent operation and interconnection with other devices. The device can also work with other gateways supporting the 433MHz wireless protocol.
Operation Instructions
1. Download APP
Download the "eWeLink" app from your mobile app store. The app is available for both Android™ and iOS devices. A QR code is provided for easy download.

2. Install Batteries
2-1. Remove the back cover of the transmitter.
2-2. Insert batteries into the battery compartment based on identifiers of positive (+) and negative (-) poles. Use two AAA 1.5V batteries. The battery is not included and must be purchased separately.
2-3. Close the back cover.
3. Add Sub-devices (Pairing with RF Bridge)
Ensure the RF Bridge is connected before adding the sub-device.
Open the eWeLink APP, select your Bridge, and tap "Add" to select the alarm. A "Beep" sound from the Bridge indicates it has entered pairing mode.
Then, separate the magnet from the transmitter by more than 20 mm. The LED indicator on the transmitter will stay lit for 1 to 2 seconds. Pairing is complete when you hear "Beep Beep" from the Bridge.
If pairing fails, move the sub-device closer to the Bridge and try again.
Install the Device
1. Tear off the protective film of the 3M adhesive.
2. Align the mark line on the magnet with the mark line on the transmitter during installation.
3. Install them separately in the opening and closing area.
Ensure the installation gap is less than 5mm when the door or window is closed.
