If you have the Harmony hub, you can try the below link to KuKu…I have the Harmony hub, Apple tv, etc…and the integration is so so…
The real problem is that I mostly watch Netflix via my Samsung tv app (built in) because it runs on 4k and the Apple tv I have is not the newest one, so no 4k. The only reason I really need Apple tv is because I use the Directvnow app on it and my tv doesn’t have that app available…
I wish there was better integration, but it is so so at this point…
I used Alexa for basic stuff, like turning on the system, etc…but as far as turning channels within Apple tv, I haven’t figured out a way (because you are using different merchant apps…) Once you use voice to control things, it’s hard to go back to even pressing buttons…it would be nice to say “Alexa, turn to Discovery channel” and have it happen. I think it’s possible with Roku? or others, but not Apple tv as far as I know…
I haven’t used this, as I’m not sure what I could use it for, but you might check out this:
