Grafana detail - so there must be some data somehow….

Does your log mention anything about the "recorder backlog" being full? I've recently been encountering a similar problem, every morning the recorder stops recording new events. Restarting HA fixes it for the day.

I just deleted the Database... seems to be corrupted

Turns out it was actually a bug in Home Assistant that was fixed in 2024.7.2: https://community.home-assistant.io/t/psa-2024-7-recorder-problems/746428

...and I spent the last two weeks chasing my tail and trying to reduce the size of the database by setting up filters for recorder... Probably not a totally wasted effort, went from 10 GiB to 900 MiB. 🔽
