Cannot share HomeKit controls
i have the new HomeKit enabled Phillips Hue system. Siri voice control works great on my device and Apple Watch. I set up the system. I've followed the apple instructions and invited my husband to share via iCloud. It shows up successfully in Homekit on his end and it shows I'm sharing with him on my end. However, Siri can't find any devices to control. I ask her to set scene but she can't find devices.
WHat hat the heck are we doing wrong???
