Unable to calibrate and power voltage stays at .08 Volts

I have few blinds at home with Shelly installed and one of them started to behave funny since yesterday. It does not open or close for more than 1 second.

Calibration also stops for the same reason. What I found bizarre is that the voltage indicated is 0.08V. I don't for certain but it feels like it is related. Tried resets/updates but nothing works. Does it mean it is faulty? Has anyone else faced such problem?

Cheers

it is not 0.08v for sure. otherwise shelly wouldn't start and the blinds wouldn't move at all!
