Sharing HomeKit problem - Apple ID is not registered with iCloud problem

I have upgraded iOS to 11.2.1 and the problem remains: I have invited legitimate, known, iCloud accounts and get the response "Could not invite <validicloudid> because the Apple ID is not registered with iCloud."

HI,

Did you have to Delete you home setup and start over for it to work? We have both Updated to the latest IOS. However, I cannot send an invite from home as I get the dreaded iCloud email address is not registered

For me it's not working. I have also installed the Elgato eve app and I could send an invitation to my wife. However she did not get any notification.

Other try: we have created a dummy home on my wife's phone and sent invitation to me, which worked. However I also did not get any notification. Both devices are on the latest iOS 11.2.1. So the issue still persists. 😟

I was having similar issues with sharing my "Home". once everyone was upgraded to the latest iOS, then i was able to share my home with others. Now that its shared though, no one can access the home remotely except for me (being the owner). Has anyone had this happen? I made sure all my aTVs are up to date, reset all of them, relogged into my iCloud id, and reset the iphones. No joy.

Same situation, the workaround didn’t work for us either. I was able to invite myself from her phone but never got the invite, meanwhile I can’t invite her at all. I wonder if Apple will create another patch.

Same problem. Tried the iOS update as suggested and received the same error.

Apple, when will this be fixed? Or will have to change to Amazon Echo hubs?

My wife can control the lights and That’s a problem.

This is pure genius (and I hope Apple is deeply embarrassed by this). I credited your post in a French website (http://www.igen.fr/ios/2017/12/que-faire-en-cas-dimpossibilite-de-partager-une-c onnexion-homekit-102371) and will do so next month for iCreate France (www.icreate.fr) thanks again!!

Just discovered this problem today and didn’t read anything until after trying to remove are reinvite my daughter. I am using iOS 11.2.5 and my daughter DOES have iCloud Keychain turned on, but am still getting the same message. It would appear that although changing that setting seemed to work for you, it is not “the problem.” was there any other changes or tweaks you made while troubleshooting this?

same issue @apple please fix your ****

Thank you Apple for wasting my time trying to figure out what’s wrong with all of my homekit devices.

iOS 11.2 came out on December 2nd so by next update they meant iOS 11.2.1

Same issue... hope apple fixes soon!

Exactly! Im stuck with this error. I spent a lot of money on homekit setup and now I am the only one who can control it. Apple really need to fix it asap! Huge issue!!!

Yes this works! We have Phillips Hue as well and that was able to invite others to join the home
