Homekit

Hello Phil Goulding,

Thank you for reaching out to Apple Support Communities.

These steps should guide you on setting up your Apple TV as a home hub:

"Set up Apple TV as a home hub

Apple TV* automatically becomes a home hub when you add it to HomeKit.

1. Open Settings on Apple TV.
2. Select Users and Accounts. Make sure your name is selected under Default User and that you're signed in to iCloud with the Apple ID that you used to set up your HomeKit and Matter accessories in the Home app.
3. Go back to Apple TV Settings, then select AirPlay and HomeKit.
4. Scroll down and select Room, then choose a room or add a new room."

More details can be found here: Set up your HomePod, HomePod mini, Apple TV, or iPad as a home hub

If you run into any issues, can you provide a few more details? Which Apple TV do you currently have? Which tvOS version is installed? Also, what happens when you attempt to set it up as your home hub?

Cheers!

So I have a new Apple TV going into another room, I would also do this step, correct?

Yep, but what if you have 5 AppleTVs and multiple HomePods? Which one does it connect to then?
