Latest version on HA green. All updates done.
The issue is not related to hardware or OS. It is just a wrong sum of values.

The energy that is charged to the battery is not used by the house. Only the discharged energy of the current day. So in the screenshot the energy of the house should be 10kWh.
And delivered energy by the battery to the grid should be subtracted.
In my case the energy was not exported to the grid from the battery but from a solar inverter that is not yet linked to HA...

I also have the same issue.

As I just installed the card I thought it was something I was doing but it appears it's a bug :-)

A great card as it allows me to easily separate the energy used by our EV charger and Heat Pumps to give me a clearer picture of our major consumers. The only issue seems to be this little bug.

I've checked everything with the Tesla Powerwall app and the figures in the old Energy Flow graph (top) are correct and are the same in the Energy Flow Plus graph (bottom) except the home consumption which is also adding the 3.1kWh imported into the battery. As our solar generation is low at this time of year all solar currently goes direct to grid so I can't currently check what happens to the home value when solar is also exported to home / battery but I'll check that in summer.

For clarity,our system has a Tesla PowerWall 2 and SolarEdge 7.9kW solar array. We have the Cozy tariff from Octopus Energy which provides cheap energy 3 times a day which is used to charge the battery and also power the home in these cheap slots. All energy for the house in the more expensive times is provided by the battery unless we exceed 3.68kW when the excess will come from grid or solar. As we have a great export rate (higher than the cheap import rate) the solar will always export to grid first (under 3.68kW generation) so at this time of year no solar goes to the battery or home.
