Description
The SONOFF DW2-WiFi is a wireless door and window sensor that connects directly to your 2.4 GHz Wi-Fi network, so no gateway is required. Pair it with the eWeLink app to see the real-time open/closed status of a door or window and receive instant notifications on your smartphone wherever you are.
It runs on 2 × AAA batteries, warns you in the app when the battery is low, and automatically saves up to 3 months of history logs. Install it in seconds with the included adhesive on door frames or window sills, then use it to trigger smart scenes such as turning on lights or sounding alarms, or bind a camera to visually confirm any activity.
Note: batteries are not included in the package. A 2.4 GHz Wi-Fi network is required.
