Modes of Operation
Regular Mode
In Regular mode, the device broadcasts the current open/closed state, illuminance, and battery status whenever the open/closed state changes. If a tilt-and-turn window or door is opened, it immediately broadcasts event information, illumination, and battery status. Two seconds later, it reports inclination angle and illumination data, followed by angle checks every 8 seconds, broadcasting updates if any change is detected.
Beacon Mode
In Beacon mode, the device broadcasts the open/closed state, illumination, and battery status every 30 seconds. This mode can be enabled via the Shelly Smart Control app. Note that battery life may be significantly reduced while in Beacon mode.
User Interface
- One push button: Press and hold for 10 seconds to pair with another Bluetooth device.
- Factory reset: Press and hold for 30 seconds (only possible shortly after inserting the battery).

Great wireless Reed switch. Easy to configure and it works well. Will be interesting to see if its any better than the 1st generation of this device, which barely lasted 12 months.
They work great and are really easy to setup in the app and Home Assistant
