returning wrong energy value

Shelly EM 50A clamp fw: 20210413-154159/v1.10.2-gb89901a

Hi,

My Shelly show what I supposed to be the correct values, except for energy 0 which vary now between 0.00 to 0.06Kw despite having a power running most of the time between 500w to 3.5Kw, it happen at once end of august.

I try a factory reset but no change. (except loss of history)

I used it with Home assistant +MQTT, My house Energy is not empty, but remain to a flat zero (not the message saying it is no data)

could you recommend what to do next ??? any chance to make it work again ?

is it the latest firmware for EM ?

Thank you for your help.

trying to investigate further:

do you think the battery could be involved ? like show in here

I put a second brand new Shelly EM firmware v1.12, I have the same problem of energy 0 in the range 0.00 to 0.06Kw (like 1/1000 of what it should be).

I am taking directly those values from listening MQTT, this is not a Home Assistant issue.

Look like it change with firmware update (previously 1.03 was running with no problem)

How do you deal with that ? anything you could do ?

1 more year, update all shelly firmware and I still the same problem.

MQTT return very small energy value despite consequent instant power.

I could not have a reliable energy dashboard into HA, it's very annoying

Help please !!!
