Help creating Home Assistant entities

I have a Denon AVR receiver and have it connected. In Home assistant I see it as well as various source inputs.

My end goal is to create one button entity that will turn it on and start internet radio, I would also tie in HA Bridge to this so that I can use my google home to say “Hey google, turn on internet radio”

So far, its only gotten to turn on the receiver - I’m not sure how to make it switch the source to internet radio. Here is my current entity

{
  "source": "NETWORK",
  "friendly_name": "Denon AVR-X2000",
  "is_volume_muted": false,
  "source_list": [
    "AUX1",
    "AUX2",
    "Blu-ray",
    "Bluetooth",
    "CBL/SAT",
    "CD",
    "DVD",
    "GAME",
    "Internet Radio",
    "MEDIA PLAYER",
    "Media Server",
    "Online Music",
    "Phono",
    "TUNER",
    "TV AUDIO",
    "iPod/USB"
  ],
  "media_content_type": "channel",
  "entity_picture": "/api/media_player_proxy/media_player.denon_avrx2000?token=130863248&cache=e292a",
  "supported_media_commands": 4029,
  "volume_level": 0.38
}

Here’s a link to one of my setups.

I use a script and call that from Ha-Bridge, use Dim for the volume and have another script for turn off. Get your source and stuff sorted first and I’ll come back with my Ha-Bridge scripts if you like when I am at home.

From the action part of that I would try…

action:
  - service: media_player.turn_on
    entity_id: media_player.denon_avrx2000
  - service: media_player.select_source
    data:
      entity_id: media_player.denon_avrx2000
      source: Internet Radio

Thanks, I’ll go ahead and do that.
