Modes of operation
Regular mode
The Device broadcasts the current open/closed state, illuminance, and battery status each time the open/closed state changes (door/window opened or closed). If a door or window, which tilts and turns, is opened, the Device immediately broadcasts information about the event, the illumination, and the battery status at the time of the opening detection. Two seconds later, it broadcasts inclination angle, the illumination, and the battery status at the moment. Then every 8 seconds, the Device checks the inclination angle. If a change is detected, the Device broadcasts the new angle value.
Beacon mode
The Device broadcasts the current open/closed state, illuminance, and battery status every 30 seconds. You can enable the Beacon mode from the Device settings in the Shelly Smart Control application. For more details, visit the Shelly Smart Control guide.
The battery life may be significantly reduced when the Device is in Beacon mode.
