Product Information
Sonoff Wi-Fi Door/Window Sensor (DW2)
A wireless sensor that detects when a door or window is opened or closed, and sends an instant notification to your phone. It connects directly to your Wi-Fi — no hub needed. Use it for security alerts, or pair it with other Sonoff devices to create automations.
Key Features:
- Instant Alerts: Get a phone notification the moment a door or window is opened.
- No Hub Needed: Connects directly to your home Wi-Fi via the eWeLink app.
- History Log: See a record of every open/close event with timestamps.
- Smart Automations: Trigger other devices when the door opens — e.g., turn on the hallway light.
- Battery Powered: Uses 2 x AAA batteries — lasts for months. No wiring needed.
- Easy Installation: Stick with adhesive tape — one piece on the door/window, one on the frame.
💡 Pro Tip: Place one on your front door and set up an automation: when the door opens after sunset, the hallway light turns on automatically. When it closes, the light turns off after 2 minutes.
