PC doesn't get discovered in HA but MQTT picks it up + no notify.your-pc service
Posting these as one support thread in case they're related.
I'm not getting a HASS.Agent integration pop up with the device discovered, but it still appears under my list of devices for MQTT. I've added the github repo for media/notfications. I'm picking up the sensors I want and I can send the test notification from the App (except GPU Temps which says Unavailable) but there's no notify service.
Solution
Ok, so apparently I restarted HA at various times, but it looks like I DID NOT reboot after updating the clients in question to the very latest 2.1.0. I definitely did not do anything with the integration side of it - I simply installed the update on the clients having the problem, and when I restarted HA a few hours later for a different purpose, I went to the integrations page and all 3x of the clients previously working with sensors, commands, etc. through MQTT, but there was no notify, nor media_player, items created suddenly were auto-discovered and I set them up immediately. No reinstall of client, no reconfiguring, so it looks like the developers took care of correcting the issue on their side. Just FYI - hopefully everyone else sees this behavior as well and I didn't do some magical mystical combination that I'm not aware to get it working!
