Firmware 1.4.4 does not measure power consumption

Hello to everyone!

I'm new to Shelly and today I received my first order of 2 units of the Shelly 1PM gen3 (along with others that are all working well ) and I started testing them.

I installed the first one, did the firmware update and then noticed that everything works, except that the power consumption measure is always zero.

I then did some troubleshooting with the second unit and noticed that with the firmware originally installed the power consumption was correctly reported.

Then the unit requested a firmware upgrade that was completed successfully and the power consumption was still correctly reported.

The unit requested one more firmware update which broke the power consumption that stays always to zero.

The broken firmware is ver. 1.4.4, apologize me for not taking note of the versions of the 2 working firmware.

Please help on resolution, eg. how to restore the old firmware.

Thank you,

Max

Actually I fixed the issue in 2 different ways, which I believe can be used either or.

1. Reset to factory and re-add the unit.

2. Main pwer cycle - off -> on

thank you!
