Would appreciate any help with Harmony script

[RoadkillUK]

Could you format your code please, take a look here.

Take a look at your harmony_xxxxxxxx.conf file in the config directory.

I have the harmony integration running, I’ll see what mine looks like.

Here we go:

turn_preamp_volume_down:
  alias: Turn PreAmp Volume Down
  sequence:
    - service: remote.send_command
      data:
        device: Yamaha Preamp
        command: VolumeDown
      target:
        entity_id:
          - remote.livingroomhub
