Deviating data from SolarEdge to HomeAssistant

Hello,

We have set up HomeAssistant as a Docker and use SolarEdge Modbus Multi to read the data from the PV system and display the energy dashboard.

Unfortunately, we have the problem that the data in HomeAssistant and SolarEdge are different.

Our grid pulls the right data, what we feed in and what we draw from the grid. But the solar production and the cumulative consumption for “Home” is about 1.266 less per kWh than on the SolarEdge website.

Has anyone here had the same problem and if so, how did they fix it?

I tracked the values with the differences:
