I recently setup my smart bridge pro 2 with homekit. Integration with Siri was straight forward on my first device. I have multiple iPads and iPhones that I want to also enable Siri control on. They're all on the same iCloud account and all have keychain enabled however only the initial device allows for the use of Siri. I have the Lutron app on all the devices, signed into iCloud and keychain enabled. My understanding is you only need to setup Siri integration on one device and the others will share the home data. Since nothing worked on the other devices I went into Siri integration on them and went through the setup steps and receive an error stating Siri integration has already been setup on a different iCloud account, which is not the case as they're all using the same one. I even added a user and sent the invitation and accepted from another iCloud account (listed in family sharing) and that device does not work either. I called Lutron for guidance and was told once a device is connected their responsibility stops there and they couldn't help me. I contacted Apple and worked with a senior support advisor who stated Homekit is not fully supported yet but they'll help as much as they can. So I signed out of iCloud on all devices, rebooted, reset Homekit config, to no avail. Apple has escalated to their engineers at this point.
has anyone had a similar experience? Any tips for getting this functioning? Thanks!
