Trigger - Substitute value not working

Configuration
1

Hi All

Can someone please tell me why this won’t work?

  - trigger:
      platform: state
      entity_id: sensor.hifi_input_function_raw
    action:  
    - service: switch.turn_off
      entity_id:
        - switch.denon_setfunc_dstv
        - switch.denon_setfunc_tuner
        - switch.denon_setfunc_spotify
    - service: switch.turn_on
      data:    
        entity_id: >
          switch.denon_setfunc_{{ sensor.hifi_input_function.state }}

But this works:

  - trigger:
      platform: state
      entity_id: sensor.hifi_input_function_raw
    action:  
    - service: switch.turn_off
      entity_id:
        - switch.denon_setfunc_dstv
        - switch.denon_setfunc_tuner
        - switch.denon_setfunc_spotify
    - service: switch.turn_on
      data:    
        entity_id: >
          {% if states.sensor.hifi_input_function.state == 'tuner' %}
            switch.denon_setfunc_tuner
          {% elif states.sensor.hifi_input_function.state == 'dstv' %}
            switch.denon_setfunc_dstv
          {% elif states.sensor.hifi_input_function.state == 'spotify' %}
            switch.denon_setfunc_spotify
          {% endif %}

Thank you

Change to this:

entity_id: >
  switch.denon_setfunc_{{ states('sensor.hifi_input_function') }}

Thank you Burningstone

It works.

What’s the difference between:

entity_id: >
  switch.denon_setfunc_{{ sensor.hifi_input_function.state }}

and

entity_id: >
  switch.denon_setfunc_{{ states('sensor.hifi_input_function') }}

At the risk of sounding flippant, the first one isn’t a valid template and the second one is.

You are missing states.xxx at the beginning of your template, but it’s better to use the states(xxx) notation as stated in the above link.

To get the state value of an entity like sensor.whatever you can use this:

states('sensor.whatever')

or this:

states.sensor.whatever.state

but not this:

sensor.whatever
