Cannot share HomeKit controls

I am having the same problem. We are using an AppleTV Gen4 as a hub. I can control the devices without issue on my iPhone. I added members of my family to the Home app. They are definitely iCloud IDs as they are part of my Family Share and the app even lists them for me to select. My wife has an iPhone, iPad and Watch. I added her phone and it worked, but her iPad did not. I tried to add from the iPad and got the "Could not invite “iCloud email address because the Apple ID is not registered with iCloud" message. Trying to figure it out, I deleted her from the Home app to start again. That was a mistake. Now I cannot add her back as I continue to get the aforementioned error message.

FYI: Our AppleIDs are on a non-Apple domain but that has never affected their functionality to date (years).

Help Apple!

Hey Farioler, Thanks!

Actually, I knew about Apple falling on their face for the third time recently by letting unauthorized people access Homekit devices. I should have made the connection. Too bad their own help desk didn't, either. Glad I still have a little hair, I can stop pulling it out now.

I am having the same issue. No iCloud. This is an awful time for this bug to pop up. Christmas guests can not control the lights in their room. I uninvited everyone on my list and now can’t add them back! My husband has been so frustrated with all the bugs with the new iOS he wants to swap to Samsung! This may have just sealed the deal. Apple please fix this!

Recent Release from Apple Fixes Invites problem so that you can only invite Strangers, and not anyone that was ever in your list or in Family sharing. so your Wife cannot control the lights or open the door, but your Neighbor that you have never invited Can.

I have returned all my uninstalled Home Kit Devices and going back to normal switches, returned the Lock on the Door, and went to a touch pad.

Depressing App had such Potential. Broke out the Arris Module using it for the Christmas Tree now.

As my girlfriend does not have an iCloud mail address we tried your solution.

And it worked! She invited my @me address and after that I could invite her back!

Finally. Not the solution I was hoping for, but at least it works.

While we’re at it. Has anybody an idea why location based automations do not work with her iPhone 8?

Location sharing is active for HomeKit in all settings in her phone. And her phone is selected as to be shared in those settings.

I think that’s a little dramatic… But to each his own. I’ve had HomeKit devices for about two years now and in general, they have worked pretty flawless… Usually my issues have been centered around a faulty device.

I'm currently having this issue also. I had to reset my Home to setup some new devices that were being difficult, but now I cannot invite others back to share Home. Even though they are signed in with their Apple ID on their devices, when I try to re-invite them back, I get Invitation Failed, Could not invite "x" because the Apple ID is not registered with iCloud. Thought the iOS11.2.1 update would fix, but still having the same issue.

Not able to add other people to homekit

Tried that and got the same error for my Apple ID...Which I’m replying with on here so clearly apple has something worth fixing here ♂

Very frustratin. I’m getting the same error when trying to share HomeKit with my wife’s known Apple ID

Fingers crossed—but these issues aren’t just with remote access. These issues are with granting /any/ access.

Having the same issue. Seems to be happening to a bunch of other people also. Apparently apple is working the issue and should have an update/fix soon.

I am having the same issue- tried logging out of all iTunes accounts still cannot send invites get invite-

Mine doesn‘t work with either @me or @icloud
