Configuring AVR source

Configuration Frontend
1

New to HA and have made a couple dashboard that have been super helpful to be able to change inputs on my AVR. I’d like to polish them up a bit by having the buttons turn yellow depending on the input source that the AVR is currently on. I just can’t seem to figure out how to do this.

Thanks for you help. Sincerely appreciated!

cards:
      - type: horizontal-stack
        cards:
          - type: button
            state_color: false
            tap_action:
              action: call-service
              service: media_player.select_source
              service_data:
                source: Xbox One
              target:
                device_id: bb64b7dcf8
            entity: media_player.living_room_reciever
            show_state: false
            icon: mdi:microsoft-xbox
            name: Xbox One
            icon_height: 50px
          - type: button
            state_color: false
            tap_action:
              action: call-service
              service: media_player.select_source
              service_data:

Is this something that isn’t possible, or did I just ask a dumb question regarding buttons? Thanks! :slight_smile:
