Error in total consumption value

[SalvadorDali6]

Check out the home consumption. I have snipped the power flow card plus as reference which uses the same sensor.
The campact card always shows less watts. No device has activated the "subtract from home" function.
Amy idea what is causing that discrepancy of around 30-50 watts?

🙏 Thx
Cheers

Update: The power flow card plus has an "override state" button in the settings. When deactivated (default) it seems to add up pv, grid and battery watts and correct the house consumption to the sum of these 3 sensors.

When activated I see the same sensor value as in the compact card.
So compact card is in fact using the actual sensor value from the inverter. No issue with the card!

even if this issue might not be related to the compact card, has anybody an idea how to handle that?
Is it just an inconsistency from smart meter/inverter reading?

Please provide your card YAML for review... if you are using a home entity the card will not calculate the home power usage from solar/battery/grid.

Also please provide screenshots of both cards at exactly the same time, these clearly are not otherwise the pv/battery/grid numbers would match.
