Q: Cannot share HomeKit controls

You made it farther than I have.   I send out a share, but it never appears anywhere on my wife devices.   Where do you see it when you say "it successfully shows up in HomeKit?"  I have never found a home kit app.   I see a home kit in settings, but that doesn't even show up on my wife's devices.  I thought maybe it came by email, but I don't see anything there either.

Did he download the same apps that you have?  but my Schlage lock will not work with any home kit commands.  And when I say goodnight it makes it two words and doesn't understand.... ........my sons phone is under my family share.....I set him up with the apps and when I try to pair with the hub it says that someone already has the home kit configured and needs to share their settings.  Logging into iCloud next...

I have HK working on guest phones now.

I removed all the invited people that were not working and re-invited them.  Siri is now able to control from their devices.  Hopefully I get a chance to test when I'm at work so I can see if the remote control works off network and away from bluetooth.  FYI your bluetooth icon will 'pulse" when its contacting a lock or bluetooth accessory.

Everything is working.... big day and night for me!!!!  Key must have been removing all home kit information from my invited guests.... and resent invites....

I was awoken this morning to all the lights going on and off as the kids were learning the commands !!! 

So the key for me, when sending HomeKit invites for Siri Voice Control from the Hue App, using the new Hue Bridge 2.0, was to be sure to use the actual primary Apple ID account email of the device that the recipient uses to login to the iCloud account. You can't use any other associated iCloud email addresses you must use the primary iCloud email of the invitee.

I had the same problem with our Hue / Homekit installation. The solution that worked for me is this: Make a working installation on one device (in my case a iPhone6 and set it all up including enabling siri voice commands in the Hue app). Next, in installation>homekit on this 'master' device, sent an invite to the other user on his @icloud.com address, this one is important, do not use the @me.com address. For some reason it only works with the @icloud.com address. Then the other user is also able to execute siri voice commands to the Hue. Works flawlessly.

Success.

OMG Thank you so much! This worked for me! I have been resetting my iCloud (which screws a bunch of stuff up) and all sorts of other tricks. But this (using the @icloud.com version of the email) worked!
