Using Shelly BLU H&T
The Device comes ready to use with the battery installed. However, if pressing the control button does not make the Device start emitting signals, you might need to insert a new battery. For more details, see section Replacing the battery.
While powered, the Device will broadcast every 11 seconds single data packets containing its battery status in percent, the currently measured ambient temperature in °C and relative humidity in percent. Every 6 hours the Device will broadcast multiple data packets for a period of one second.
If you press the control button, the Device will immediately start broadcasting for a second the currently measured ambient temperature in °C and relative humidity in percent, as well as a button-pressed event.
To pair Shelly BLU H&T with another Bluetooth device, press and hold the control button for 10 sec. The Device will await connection for the next minute. The available Bluetooth characteristics are described in the official Shelly API documentation at https://shelly.link/ble.
To restore the device configuration to factory settings, press and hold the control button for 30 seconds shortly after inserting the battery.
