Thank you for your response
Yes, the appletv 4k in question here is our home’s hub
All HomeKit devices have parent apps that are working fine with the devices controlled by the scene I am using, all have latest firmware, etc - my problem is when I use an Apple HomeKit Scene to control the devices - in this case two separate lighting switches - all was working fine for past several years until recent Apple TV iOS update to 16.
Yes all devices are on the same network
Other SIRI commands work fine (eg “open app”, “What’s the temperature”, etc)
I went into the settings and toggled on and off this appletv being the hub, then I forced a restart like you recommended, then i pulled the plug, waited and plugged the power cable back in
Tested SIRI again to turn on a “scene” and it worked fine, recognized the scene and executed it without problem. Then later in the day returned and tried again only to have the same issue where it responds saying it can’t find anything like that, then I repeat the same command and it works fine. When I am done with the lights being on, I issue a command for it to use another scene that turns them off and again it says can’t find anything like that, so I repeat and it works fine.
