Perhaps a combination of Logitech harmony hub and this:
Roon Extension: Deep Harmony - rich feature set for Logitech Harmony - Tinkering - Roon Labs Community
I have Roon controlling switching everything on and changing inputs etcand amp volume (my main hifi is also a hybrid AV system with a stereo amp in HT bypass mode for music, so a more complex than a pure hifi setup it still all integrates), volume mute and from harmony to Roon, the remote control control’s Roon’s transport and other functions.
