[bug] Solar production shows value of total life time production instead of delta (day, week,..))

HA Core 2024.11.2
HA Frontend 20241106.2

fenecon energy management system (fems) is integrated via modbus.

In general all is working as expected, but sometimes the statistics is wrong because eventually the total life time production value is taken for the production per day value:

First two screenshots how it should look like:
Solar production of 18/12/2024:

…and the corresponding entity of “FEMS_ProductionActiveEnergy” (cumulative energy)

And here THE ISSUE:
Solar production of 19/12/2024:

…and the corresponding entity of “FEMS_ProductionActiveEnergy” (cumulative energy)

What could cause this issue and is there anything I can do?

Thank you!

You can fix in developer-tools/statistics, Adjust Sum dialog for this statistic.

Generally this can happen if your sensor reports a bad value, like a blip of “0” or something.

Hi karwosts,

thank you for your fast reply!
So this means that I have to manually enter the correct value, right? Ok, this will solve the symptoms and help my statistics. But because I face this issue quite often, it is not really a satisfying solution. In my opinion this must not happen and I also don’t see any wrong values from the sensor. Technically it should be possible to avoid this behavior.

This is my list of outliers:

I can’t say exactly why it happens. Please open an issue with your integration provider and perhaps he can help you debug further.

But its nothing to do with Energy, just the statistics gathering platform is getting a wrong value somehow.
