"Home hub not connected" HomeKit error
The Home app now persistently states that the home hub is not connected, with the usual issues for automations. This has been an issue for the last 48 hours or so - not connected to any obvious software update.
I have three home hubs - Apple TV 4K and two HomePods.
I have:
- followed all of the instructions on Apple's page on troubleshooting this issue
- rebooted all of them
- signed out of iCloud and back in again on all of them
- checked that the software is updated on all of them
- rebooted my router.
And it still doesn't work. All three are listed as "standby" in the Home app (on iPhone and iPad. I've rebooted both of those as well, and checked that the OS is up to date).
I have also disabled the AppleTV as a hub, at which point it shows as such in the Home app, but the HomePods don't pick up as the hub even after power-cycling them.
Anyone got any ideas how to fix this, as it is more than somewhat annoying?
[Topic listed as AppleTV because Apple doesn't have a 'Home' topic. No idea if it is the TV or the HomePods or something else.]
