I have successfully setup HomeKit with many Hue bulbs and some iHome Smart Plugs. I've successfully shared all of this with my wife's iPhone and it's been working great. Today I added two more Hue bulbs. In the "Siri Voice Control" settings of the Hue app I needed to "sync" the new bulbs. Once I did that I could immediately control the new bulbs using Siri on my phone. Further, I use the "Home" app for organizing my HomeKit devices and I was able to go in there and see my new bulbs, control them and add them to a new HomeKit Room and control them using Siri using the Room name. In short: everything looks good. Except one thing: the new bulbs and Room will NOT show up on my wife's iPhone. Does anyone know how to get her iPhone to sync the new stuff?
