Description of SONOFF WiFi Wireless Door Window Sensor DW2

The Sonoff DW2 WiFi Door/Window Sensor is an upgraded version of the DW1, using WiFi instead of RF, so it connects directly to your router without any gateway. It consists of two magnetic parts that detect door or window open/close status and send alerts via the eWeLink app.

It supports both detection and automation, allowing separate actions for opening and closing (e.g., turn lights on/off). The sensor can wirelessly control other Sonoff and SmartWise devices through smart scenes, with no wiring required.

Powered by 2 AAA batteries, it provides instant notifications to your phone and can also integrate with compatible cameras for real-time monitoring, making it a simple and effective smart security solution.

Note: Batteries are not included with the Sonoff DW2 WiFi Door/Window Sensor. Please purchase 2 × AAA batteries separately for proper operation.

How to Install and Set Up (App & Device Guide)

Before Installation

  • Ensure your Wi-Fi network is 2.4GHz. The device does not support 5GHz Wi-Fi.
  • Download the eWeLink app from the App Store (iOS) or Google Play Store (Android).
  • Register and log in to your eWeLink account.
  • Ensure the sensor has fresh batteries installed (2 x AAA 1.5V batteries).

Physical Installation

  1. Identify a suitable location on your door or window frame. The main sensor unit and the magnetic strip must be mounted on adjacent surfaces (e.g., one on the door and one on the frame).
  2. Clean the installation surface thoroughly to ensure proper adhesion.
  3. Peel off the protective film from the 3M adhesive on the back of both the main sensor unit and the magnetic strip.
  4. Attach the main sensor unit to the fixed part of the door/window frame.
  5. Attach the magnetic strip to the moving part of the door/window, aligning it with the main sensor unit. Ensure the alignment marks on both parts face each other.
  6. The gap between the main sensor unit and the magnetic strip must be less than 5mm when the door/window is closed for proper operation. This is recommended for non-metallic surfaces.

Device Pairing with eWeLink App

  1. Open the eWeLink app on your smartphone.
  2. Ensure your phone is connected to the 2.4GHz Wi-Fi network you intend to use for the sensor.
  3. Press and hold the pairing button on the main sensor unit for 5 seconds until the LED indicator flashes rapidly. This indicates the device is in pairing mode.
  4. In the eWeLink app, tap the '+' icon at the bottom center or top right to add a device.
  5. Select 'Add Device' and follow the on-screen instructions. The app should detect the DW2 sensor.
  6. Confirm your Wi-Fi network and enter the password when prompted.
  7. Wait for the app to connect to the device. Once successfully paired, the LED indicator on the sensor will stop flashing and remain solid for a few seconds before turning off.
  8. You can rename the device in the app for easier identification (e.g., 'Front Door Sensor', 'Bedroom Window').

Operating Instructions

Monitoring Device Status

Once paired, you can view the real-time status of your door/window sensor directly from the eWeLink app. The app will display whether the sensor is 'Open' or 'Closed'.

Receiving Notifications

The sensor is configured to send push notifications to your smartphone whenever the door or window it is attached to changes status (e.g., opens). Ensure notifications are enabled for the eWeLink app in your phone's settings.

  • Trigger a SONOFF camera to record when the door sensor detects an opening.
  • Turn on lights when a door is opened.
  • Activate an alarm or send a notification to other family members.
