Posted new thread here in Hacks rather than continue in the announcement/API thread.
Got HASS installed and updated and added entries for Channels. Currently have an ATV 4K, Shield 2017 and FTV2 in the lounge. Driving my wife nuts - she wants me to settle on one - but got to test Channels!!
On HASS I therefore have 3 new Channels entries which I can control happily. I also however have 3 entries for the generic devices (Shield, FTV and aTV). On the aTV for example the apple_tv component displays everything the aTV is playing - including Channels so the channels component adds nothing new.
Can you think of a reason I might use the channels component rather than use the apple_tv one?
