energy dashboard bug

[Krawuzzi]

The problem

Since the 2025.5.0 update, the energy dashboard graph is showing wrong values for the battery output energy. Battery output energy values (green) are much smaller than before, instead the PV self usage values (yellow) are higher. Please see the screenshots below.

2025.5.1

What was the last working version of Home Assistant Core?

Additional information

Couldn't find any documentation on this bug yet. I tested both 2025.5.0 and 2025.5.1, same problem.
A rollback to 2024.4.4 via the terminal (ha core update --version 2025.4.4) fixes the energy dashboard again.

Which inverter is being used? Is there perhaps a calculation error here? For Fronius with battery storage, helpers must be created.

I'm using a Solax X3-Ultra-25kW.

And the configuration is still as described at https://www.home-assistant.io/integrations/solax/

On my Fronius with BYD energy storage, the display in the energy dashboard works perfectly.

So I suspect it's due to your integration with Solax?

What i forgot to mention, the single day view shows the real values, only the accumulated views over several days has this problem.

As example, May 1st:

So I suspect it's due to your integration with Solax?

Thank you for that info. I'm using the standard daily values from the Solax integration for the energy dashboard.

I think there was a change somewhere in your entities at Solux?
