Strange behavior with stats no longer updated?

For the second time this week, it seems the stats stopped to be updated at a certain time, only a restart cured the problem. I suspect something related to stats because the ‘current’ value displayed (690W) is correct, but not the value used for the graph (3000W).


Any idea will be welcome…

Looking in the logs:

2024-11-30 13:00:01.238 ERROR (MainThread) [supervisor.homeassistant.module] Preparing backup of Home Assistant Core failed. Check HA Core logs.

But nothing in the Core logs at 13:00.
Checking Google Drive backup add-on, and indeed starts daily at 13:00. Will look in that direction…
