Sonoff DW2‑RF RF Door Window Sensor sends instant alerts when doors or windows open. It links with a 433 MHz RF bridge and works through the eWeLink app, making it easy to build smart home scenes like turning on lights or cameras automatically.
This wireless sensor runs on a 12 V 27A battery and draws just 1.5 µA standby current, so it lasts up to two years on one battery. Use the included adhesive pads to install the compact units on door or window frames, keeping them aligned within 5 mm to ensure reliable detection.
When the magnet and sensor separate, DW2‑RF transmits a signal up to 50 meters away, triggering alerts, lights, or actions via the RF bridge. It supports smart scenes and IFTTT—such as switching on hallway lights when you enter. You can also share alerts with your family through the app for better home monitoring.
Made from flame‑retardant PC V0 material, this sensor works in temperatures between –10 °C and 40 °C. It meets RF safety standards and offers easy, tool‑free installation. The device logs open/close history so you can check events for up to three months, giving insight into activity at your entry points.
Sonoff DW2‑RF is a reliable RF Door Window Sensor if you want extra monitoring without drilling or wiring. It complements other Sonoff smart devices, upgrading even old homes with minimal effort and maximum peace of mind.
