Thanks both.
I’m running on a good spec Synology, so don’t think HW would be the issue.
Looking further into my logs, I think I need to start there. I can see some code changes have broken things but I know I’ve jumped some versions of HA so I’ll clear those up.
I’ll post my automations but they’re quite basic too… But to add, I also had a corrupt DB again last night (exact same issue as this) - I removed the 3 DB files (main and two temps) and HA booted again.
