Denon: control subwoofer level

Configuration
1

Hello,
i am trying to add my subwoofer channel level to home assistant,
i create the automation + configuration,

the real problem is how can i use template value to work in the action.

configuration:

input_number:
  subwoofer_level:
    name: Subwoofer Level
    initial: 0
    max: 12
    min: -12
    step: 0.5

automation:

- alias: '[Denon] Subwoofer Level'
  trigger:
    platform: state
    entity_id: input_number.subwoofer_level
  action:
  - service: denonavr.get_command
    data:
      entity_id: media_player.denon
      command: /goform/formiPhoneAppDirect.xml?CVSW%20{{ ( states("input_number.subwoofer_level") | float *10 + 500 ) | int }}

the template value is used to convert the input number ( -12 | 0 | +12 ) to numbers that the denon work with ( 380 | 500 | 620 )

Thank you

Thank you!
IN case anbody wants to use node red instead, here is the sequence for that:

Doesn’t seem like we can read the value stored in the receiover (which would be usefull when the subwoofer volume is changed using the remote control).

Sorry I know long time ago, but as much as your post helped me, also it doesn’t… :frowning:

I understand now what platform is used “telnet” but CVSW%20 is not working for me. What i don’t get is why are you using the “%20” after “ChannelVolumeSubWoofer”?

I hope you can help me with that :S

%20 is just space in ASCII Encoding.

You must check that your avr support this api method,
Which avr you have?

so what works for me:

create a number helper:

input_number:
 subwoofer_level:
   name: Subwoofer Level
   initial: 0
   max: 12
   min: -12
   step: 0.5

automation in yaml modus:

alias: Subwoofer
description: ""
trigger:
  - platform: state
    entity_id: input_number.subwoofer_level
action:
  - data:
      entity_id: media_player.denon_avr_x1500h
      command: /goform/formiPhoneAppDirect.xml?CVSW%20{{(states('input_number.subwoofer_level') | float * 10 + 500) | int }}
    action: denonavr.get_command
