Apple TV won't show up as home hub in iPhone iOS 10 home app

I'm trying to set up the AppleTV 4th gen to act as a home hub but it won't show up in the iPhone home app.

Both devices use the same iCloud, tried logging out and back in but nothing, two factor authentication is enable, location is enabled, iOS are both up to date, connection to the same wifi ..

Also I checked in my apple ID page and all devices show up correctly, but I can't figure out why the Apple TV is not recognized by the iPhone home kit app.

Any help appreciated
