If it’s battery powered
1. Wake it up
Press the button once to wake the device (it stays awake for about 3 minutes).
Check if it appears in the Shelly app.
2. Power cycle
Remove one battery for 10 seconds.
Reinsert the battery and press the button once to wake it up.
3. Factory reset (last resort)
Hold the button for 10 seconds to reset the device.
Set it up again from scratch in the Shelly app.
If it’s USB-C powered
1. Power cycle
Unplug the USB-C cable for 10–15 seconds.
Plug it back in and wait 2–3 minutes for it to reconnect.
2. Refresh the app
Pull down to refresh the Shelly app, the device should appear more frequently than when on battery.
3. Button functions
All button actions (wake-up, setup mode, reset) work the same as in battery mode.
USB power makes the device respond more quickly to commands.
💡 Tip:
USB power keeps the device more responsive, but it still uses short sleep cycles to ensure accurate temperature readings.
