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

I had to follow the instructions above and do the invites from within the Philips Hue app. Additional information for those it may help - I was unable to add others, even after having them log out and into iCloud. I had to use the Philips Hue app.

Thank you for the great help provided in this thread!

Having the same problem when already upgraded to 11.2. Apple Support said that there will be another fix/upgrade properly this week

Wish I had of read this first. I removed my husband and now can’t add him back. He was only missing a couple of new lights I had installed.....now he has nothing! Hurry up Apple and fix this.

You are right. I've updated Apple TV, My Iphone, My GF iphone and tried reinvite and it didn't work saying it's not enabled for icloud. Must be still disabled server wide.

Even after upgrading to 11.2.1, I am still getting the error that my wife’s Apple ID is not registered… Anyone else having that problem?

I assume you have updated your and your wife's device and your apple tv

Try invite using the HomeKit accessories... it works for me!

I have a different Apple ID than my wife. When I reversed who sent the invite, now her to me, it worked! Please explain that Apple. Still trying to reconfigure devices ....

This Feature was Disabled by Apple, they cannot disclose why they disabled it for security reasons, only that its no longer a shared Application only the Main user can access Home Kit Devices via the HOME App.

They would not give me a timeline on the next update from Apple, I would suggest you just get the Native APP for each device and put on your family iphone so they can control devices.

Listen Apple, before you start doing anything to fix the iCloud error, the first thing you need to do is to copy and paste this post on the front page of your wedsite and don’t forget to give dbaker0926 credit for doing it to all the disappointed Apple users.

I have had this same issue, and even attempted to delete the entire "home" and restart. I was able to invite both parties back, and it says "invitation pending" but there is no invitation on their devices. I have tried canceling the invite and resending, and I get an error "this email address is not associated with an iCloud.com email" even though both emails are @icloud.com ones.

What gives?? I'm on iOS 11.2... and my device works flawlessly. This is so frustrating!! Would appreciate any updates.

I have the same issue trying to add my wife. Initially I was able to add her, but she could not see all the devices so I tried removing her and re-inviting and the "Apple ID is not registered with iCloud" error started. I believe this was before I upgraded to iOS 11.2. However still occurs after upgrading.

She also can not login via desktop to https://appleid.apple.com. It will initially login, but immediately logs her out stating session has timed out for your security. Not sure if that has anything to do with the issue. She has iPhone 7 with iOS 11.2 and iPad 2 (don't think it has been updated to 11.2) associated with her iCloud account.

I have iPhone 6 with iOS 11.2, apple Tv 4k with iOS 11.2.

For me everything is working, although I had to go through a lot of hoops to get Apple TV to connect to Home and get automation working. I am really enjoying my HomeKit devices and features in Home app, but really hope Apple can get these bugs worked out. It shouldn't be this hard and error prone. I am concerned I may regret my investment in an array of HomeKit devices.

Although the EVE app does work for invites, none of your Guests will be able to see the HUBS and have no remote access to any devices, they have to be on WIFI and get annoying message on HOME stating Hubs offline
