Home app notifications on macOS

I signed into my iCloud account on a secondary computer and then proceeded to disable certain functions I don't want enabled on that computer. Really the only thing I wanted was iCloud Drive, passwords, and safari. I disabled everything else, but that doesn't seem to actually work. I had to manually launch Messages and FaceTime and sign out of those apps to stop getting messages/calls from them. But even though I have the Home app disabled in iCloud and launching the Home app shows it's not signed into my Home, I continue to get notifications for actions that occur in my home (primarily around Garage door opening/closing). Seems to be a pretty significant bug when iCloud functions are turned off but keep working. Wondering if anyone else has ran into this.
