I have never gotten Home Kit to work. The first time I tried was about six months ago, after buying an iDevices WiFi outlet. The very first time I tried launching Home Kit, the system stuck on "Loading Accessories and Scenes" interminably. After reading that others would eventually get a message that they needed to reset Home, I tried leaving it for days. No matter what I tried, same result. I've tried the following: Erase phone and restore from backup Erase phone and set up as new phone Use a different phone Use a different iPad Using a different Apple ID works, but there's no way I'm switching Apple IDs with the years of emails and app purchases I have attached to this one. So I called Apple Support, since the phone has Apple Care. I've called Apple Support for two significant issues over time, and both escalated to the top-tier support people. And in both cases the result was the same. Support escalation to senior advisor Install stuff to collect logs, etc. "We're waiting for the analysis of the logs" Service advisor starts missing our follow-up appointments Service advisor stops responding to my emails I give up in frustration It really feels like this is written into their procedures somewhere. "If the tech team is unable to determine the source of the issue, or determines the source but is unable to provide resolution, cease responding to the customer, who will normally give up out of frustration." Clearly, there is some Home Kit data stored in iCloud, and clearly mine is irrevocably broken. The idea that Apple simply can't resolve that--can't clear out Home Kit data for someone whose Home Kit HAS NEVER WORKED, simply amazes me.
