More info


Sonoff DW2 is an opening/closing sensor 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 a WiFi wireless communication module. It can send notifications about the occurrence of an event and, in conjunction with a camera, inform about who entered the room. The device allows you to read data from the last 3 months, thanks to which the user can trace past events. Combined 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 a tape on the wall, and the other on a door or window. It is battery operated and the application will inform the user when the battery charge becomes too low.
