More info


Sonoff DW2 - RF is an opening/closing detector designed for installation on windows and doors. It is an excellent security device informing, for example, about an undesirable entrance to the house. The sensor is equipped with an RF wireless communication module operating at 433 MHz. For full functionality, the sensor should be connected to the Sonoff RF Bridge base station, which will allow you to use the full capabilities of Sonoff DW2 also via the Internet. The sensor can send notifications about the occurrence of an event, and in conjunction with a camera, it can inform about who has entered the room. The device allows you to read data from the last 3 months, so that the user can trace past events, if necessary. Coupled with smart lighting, it can also add the function of automatically turning on the light in the room when you open the door.

Sonoff DW2 consists of two elements, one of which is mounted in a non-invasive way with tape on the wall, and the other on the door or window. It is battery-operated, and the low power consumption means that it can work up to 2 years on one battery.
