Shelly TRV not powering on

When the Shelly TRV battery is fully depleted, it needs to be charged for up to 48 hours before it can be powered on.

 After at least 24 hours of charging, try turning it on by pressing the reset button once. Continue charging until the battery is fully replenished.

If the device remains unresponsive after a full charge, a reset may be required.

 To perform the reset, short the battery using a flat screwdriver, following the steps shown in the attached video.
