Additional information

I have 4 solar entities in my energy dashboard. 3 for currently active devices, 1 for historical device that has since been removed but still has history (or did, anyway, before my DB crashed a while ago). In any case, I deleted that dead entity, and the problem still occurs in the energy dashboard.

Here is what the dashboard looks like for today so far :

I did upgrade fairly recently, less than 2 hours ago. I don't expect new solar production data to show up right away. But old data should be there, still. It's missing also for all previous time periods.

Check your entity in developer-tools/statistics, it may have some issue that needs correcting.

@karwosts Thanks. I did a restore of my 2024.5.0 backup before your comment. The issue still showed up ! I then rebooted HA, and the problem was solved. Then, I upgraded to 2024.5.1 again. And the problem didn't reappear.
Very strange that it only showed up for one of the two 2024.5.0 -> 2024.5.1 upgrades I did .
Is it expected that one needs to reboot HAOS after a minor upgrade ?
