Ghost Home Hubs Not Responding

Similar story on my end. I have an AppleTV that was errantly added to my primary residence (in Home app) while setting the device up in a second home. I removed the device in the Home app and reset it before adding it back in the correct home within the Home app. This was months ago. The device works properly (as AppleTV and HomeHub in secondary residence), appears in the correct home within the Home app, and did not appear as unresponsive in my primary home until iOS 18 - even though it is not listed as a device in any of my primary home's rooms. I removed the AppleTV from my secondary home within the Home app as well as from my list of devices in iCloud. It sill shows as unresponsive in my primary home.

There are quite a few posts elsewhere on this issue but none (that I have seen) have a viable fix.

I finally came across a solution that worked for me in the Reddit megathread. I initially tried the reset of my iCloud password but that didn’t work and I still had 3 ghost hubs. I factory reset all of my Apple TVs and then set them all back up (don’t know if this step is actually necessary or not so maybe skip and give it a try). Then on my iPhone I went to iCloud>Saved to iCloud> and toggled off Home. Then I restarted my iPhone, toggled Home back on in iCloud storage and my ghost hubs all disappeared. I had to repeat this process on my iPad to get them to disappear there. Hope this is a universal fix! 🤞

Do you know if your ghost hubs were one of the AppleTVs you reset? Also, do you have other Mac, iPhone, or iPad devices in your household in addition to the iPhone and iPad you did these steps with?
