Cannot invite family members to HomeKit

Finally fixed the problem.

1. I created a dummy "Home", invite my wife by apple ID

2. my wife's iphone received invitation, accept it

3. go to my Home (The real one), cancel the invitation that my wife haven't received it at all, and then re-invite her using apple ID.

4. my wife's iphone received invitation, accept it

5. delete the dummy "home", done!

Good question. I know for sure that she has a 2 step verification but I didn't verify if it was 2-step or 2-factor which does make a difference.

She's at work at the moment so I'll verify this evening. Hoping this is the problem.

Follow-up: I verified and she actually has 2 factor authentication enabled so it's not that.

Read on another thread about a developer updating to the iOS 12.2.5 bèta and suddenly having no more problems inviting others. So it's probably just a system software bug.

If you have Hue lights, go to settings in the hue app and click on “Share Home”. When I did this I was able to sent the invite and it showed up as a pending invite in the “Home App”. I’ll follow up with a post later to let you know if it works.

Tried that with the Hue app, with Eve (Elgato) and with Security (Netatmo). Although the invitation seems to be sent as you get the pending invite, it never gets sent (or received at her end). The other apps just don't perform the check Home app does but the problem persists.

Even after the update to 11.2.5 on all devices, no go for me. Still get the error message that the Apple ID (whether mine or hers I don't know) is not registered with iCloud.

I sent another invite from the Hue app and it shows up as a pending invite in the Home app but she's not receiving anything.

daughter's phone - iphone 6s, ios 11.2.5 - cannot invite her from my iphone X ios 11.2.5. Same error, not registered at icloud. funny because her email is @icloud.com. She has two factor enabled.

Not funny that this doesn't work. Had no trouble inviting my wife's iPhone X, or my other daughter's iPhone 6s.

Are we just waiting for another software update to fix this? Do we know?

I fix my problem by deleting all the devices in Home on my iPhone X and then flipping to my wife’s iPhone X as the starting point. From her phone I then shared to me and was able to accept invitation. I then added devices to her phone and they showed up on mine. No idea why it didn’t work the other way around. I’ve been on and off the phone with Apple engineering for a week with no resolution. This was the only workaround I was able to find

I have been using ihome devices with no trouble sharing for a long time - I think 2 years - with no problems until the last week or so. I have tried everything that I can think of to get this to work on my wife's ipad mini and iphone 8 plus. I has worked on those for a long time with no problems, but not now. I'm kind of tired of seeing the Apple guy say it's fixed every once in a while when it obviously isn't.

We finally located the invitation in the receiving phone’s home app. Check there instead of email. I did have to do a series of deleting and reinitiating home kit due to using an old Apple TV, but I’m not sure if that effected the invitation showing up in the receiving phone app.

HUGE thanks, RoadKingMacGuy.

I installed an iDevice socket using my account and sent an invite to my mom so she can control lights with her iPad. She was checking Mail app...cause, hey, it,s an email..to no avail. Sure enough, the invite was waiting in the Home app.

Hey Apple, how's about putting a small blurb instructing folks that the invite is sent to the Home app and not Mail!

The problem has been fixed now with the latest tvOS and iOS updates.

Hi, I have the same problem too. I contacted the Italian apple support and they confirmed that a software update, which will be released next week, will solve the problem.

Just installed TVOS 11.2.1 and IOS 11.2.1. Still have the same issue. Cannot send an invite to my wife’s valid icloud account.
