Can you see HomeKit accessories on the Appletv?
I have an Appletv 4K. I was told that you can see the accessories on the menu sidebar. I have my hub set up but cannot see any accessories.
You configure your accessories from the Home app on iPhone or iPad.
There are also third party iOS apps that give a pretty good overview and controls. Eve for HomeKit, Home+ 4, Controller for HomeKit, Hesperus, Devices Control for HomeKit, etc.
You can see certain video accessories (e.g. door cam) on Apple TV. Use HomeKit Secure Video - Apple Support
You can see certain audio accessories (speakers) on Apple TV. Use tvOS Control Center on Apple TV - Apple Support
