Homekit + Family Sharing not working
I have setup homekit on my iPhone X and I have some Elgato Eve and Philips Hue accessories configured.
I also have my Apple TV (4k) as a hub and my Apple TV 4 as a spare hub.
This all working perfect!
I also have Family Sharing active for my wife and daughter so that we can share iCloud storage, purchases, .... this is also working great.
But know I just want to share "my home" from homekit with my family and ..... this is a disaster! I can't even invite my wife or daughter because I get an error that their email address (which is also their AppleId) is not registered on iCloud. But I can login using that email address on iCloud! So it is their iCloud account and Apple Id and Email address at the same time.
I have tried everything .... the only solution I can think of is to use a spare device (iPhone, iPad) and leave that at home so that everybody needs to use that to turn on the lights or the TV. But that is an expensive power-switch!
So I really hope someone can give me some advice how I can share my Homekit home with my family using family sharing.
Thank you.
