Reliably detects open windows and doors and interacts with other products
This device detects open windows and doors and reports them to the app. In combination with the radiator thermostat, the temperature in the room is lowered during airing so no energy is wasted. Intelligently connected to motion detectors or smoke detectors, the alarm is sounded in the event of unauthorized entry. It is unobtrusively attached to door and window frames.
