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

There is new updated by Apple for iOS and Apple TV that fixes this issue. Go ahead and update to 11.2.1

I used Elgato Eve app to invite my wife. Even I dont have anything from Elgato. Everyrhing works fine now. Weird thing is Elgato eve app does something Homekit dont! Apple should think about this.

I have been working on this since 2 weeks.... since the time I got my Ecobee3 thermostat... thanks for some of the comments here but I have not got it working :-)

Trick is, as stated in one of the post, to ensure all ur devices are on 11.2.1 (or hopefully above).

This is what I did:

- upgraded my wife mobile and her iPad to 11.2.1

- both my phones were 11.2.1

- earlier I had added the ecobee3 on my phone and I was adding her using the home app but that use to give the error “the xxxxxx@gmail.com is not registered to iCloud” and when I tried to create a home at her iPad and add myself it use to say invitation pending but I will not receive anything. Once we had all 4. Devices on 11.2.1, I removed the home from my iPhone (as the iPad was on her Apple ID) and then converted her iPad to iHub and then added the ecobee3 thermostats to her device

- then I invited myself from her iPad and got the invitation instantaneously

Now I have all 4 devices with home kit having the ability to control the thermostats

Hope this works for you guys as well..

PS: I also turned keychain ON on all devices, not sure if that helped as well but I read in some blogs that for HomeKit you need to have this turned ON.

Good Luck

After pulling my hair out trying to invite them via iCloud email address I tried inviting them using their 10-digit telephone number and Voila! It worked like a charm.

Well the good news is I have mine working again as well… The bad news is you still cannot invite from the Home app inside of iOS.

If you have a third-party apps such as the Phillips hue app, Elgato eve, etc.… You can invite someone from there and the invitation will go through.

This was not working prior to the update but I can confirm that it does work post update.

I was also having this problem and updated to 11.2.1 in the hope that it would fix it, but it didn't. I found an old solution (about a year old) which did work - remove all the guests from your House and then re-invite them and the error goes away.

Great news: I just downloaded iOS 11.2.5 Beta 2 and the bug has FINALLY been fixed. No work-around (like inviting via a user’s iCloud email, which didn’t work for me) - it just works like it’s supposed to. I’m guessing the new iOS will be pushed out to everyone in the next few days.

I think this was mentioned earlier in the thread....I was finally able to get an invite to work by using my wife’s cell phone number and not her email. The invite came across instantly and now she can see all the HomeKit devices. Now if iHome would get their cloud service fixed so Alexa would work.....

Fix is released. 11.2.1 looked liked it is needed on hub service TV or iPad, and all devices that need to be connected for all parties.

There is a 11.2.1 release today. It reportedly "fixes bugs including as issue that could disable remote access to shared users of the Home app."

Tried it before. What worked was using @icloud.com instead of me.com

Hue was the issue. Worked perfect when I invited from hue! Thanks!

Update all of your devices to the latest version and everything will be ok.

I have the same isue, but when update all phones and apple tv, everithing start working !!

Hi guys. I was having the same problem until I used my wife’s phone number instead of her email address. It went right through. I hope this helps everyone.
