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