Hello world!
So I put the code in the configuration.yaml and now Im able to see 2 entities but they are both missing a unique ID. I only see these entities when i go to settings, Devices, entities and search for reciever then I see them both and one of them is called zone. the other one called reciever and there i can turn the onkyo on or off, volume up and down and mute function, it is not very responsive but i can live with that. now i would really need help fixing the unique ID problem. I went through the documentation and I couldnt really figure out how to solve it.
Thank you in advance!
