I just finished a component (media_player subcomponent) for Rotel amps
Code is available here : https://github.com/elric91/homeassistant_rotel
As it is the first time I’m developping a component, furthermore using asyncio, there may be some better ways to code it 
. PR for correction / enhancement / improvement are welcome
Code updated to work with 0.84 changes
This is excellent, thanks for sharing. 
I have a Rotel RT1570 as my gateway to my Rotel stack of tuner/ amp/pre-amp and was wondering if I can use this component to control these?
I have installed your component and HASSIO has picked up the entity media_player.rotel_a14 but there is not much going on…
