Properly clean up after deleting HACS?

My automations stopped running a few days ago, and have just started running again after deleting the HACS integration (which I wasn’t using for anything important anyway). I have rebooted Home Assistant Green twice since removing it, but still get the following in my log when restarting:

Home Assistant Core

2024-09-30 13:11:34.019 WARNING (SyncWorker_0) [homeassistant.loader] We found a custom integration hacs which has not been tested by Home Assistant. This component might cause stability problems, be sure to disable it if you experience issues with Home Assistant

Is there something more I can do to clean this up?

HACS should not affect your automations. The warnings you have pasted are default warnings for every single HACS integration. I suspect there’s something else, look through your logs.

HACS is an installer for stuff and it lets you know if there is an update to something it helped you load. I hope none of the stuff you loaded thru HACS gets an update pushed by the Author, because now you will not know.

The warning will appear for every Custom Integration regardless if HACS helped you load it or not.

Later: Looks like the automations have stopped again! I’ll have to check out the next error (Reolink)

And later still: The Reolink problem was obvious - I don’t have the latest public release firmware cos I was working through a bug with one of the devs and they pushed a version onto my devices that isn’t out yet. So that integration will have to be disabled for now…

I’ll probably reinstall HACS now

That’s not quite correct.

the warning posted was only specifically for the HACS custom integration itself. It’s not the same warning for all the integrations installed via HACS. They would all/each get their own warning.

it doesn’t explain why the warning was still there after removing the HACS integration tho.

there must have been some remnant of the HACS integration left over after removal.

Exactly.

Thanks for the help everyone, I don’t know why the Reolink thing didn’t occur to me sooner, I’ll need to re-enable when the public release matches the one I have and the reolink integration is updated. HACS is reinstalled and everything seems to be working now. If I ever have to uninstall HACS again I will read up on how to do so thoroughly.
