Passing variables into conditional script execution

Configuration
1

I’ve gone through many posts and tried a few times to fix my code, but to no avail.

I am really hoping that someone can point out where the following is failing when trying to pass variables between scripts. Fairly certain it’s in my IF ELSE statements:

fan_set_speed:
  alias: Fan (speed)
  sequence:
    - service: input_select.select_option
      target:
        entity_id: input_select.{{ room }}_fan_speed #Variable here
      data_template:
        option: "{{ percentage }}"
    - service: script.fan_on
      data_template:
        room: "{{ room }}"
fan_off:
  alias: Fan Off
  sequence:
    - service: remote.send_command
      data:
        entity_id: remote.rmpro_remote
        #Variables Below
        command: >
          {% if "{{ room }}" == "b1"  %}
          {{ 'b64:' }}
          {%-elif "{{ room }}" == "b2" %}
          {{ 'b64:' }}
          {%-elif "{{ room }}" == "b3" %}
          {{ 'b64: ' }}
          {% endif %}
    - service: input_boolean.turn_off
      target:
        entity_id: input_boolean.{{ room }}_fan_state
fan_on:
  alias: Fan On
  sequence:
    - service: input_boolean.turn_on
      target:
        entity_id: input_boolean.{{ room }}_fan_state #Variable here
    #    - delay:

    - service: >
        {% if is_state('input_select.{{ room }}_fan_speed', '33') %}
          script.fan_33
        {% elif is_state('input_select.{{ room }}_fan_speed', '66') %}
          script.fan_66
        {% elif is_state('input_select.{{ room }}_fan_speed', '100') %}
          script.fan_100
        {% endif %}
      data_template:
        room: "{{ room }}"
fan_33:
  alias: Fan (min)
  sequence:
    - service: input_text.set_value
      target:
        entity_id: input_select.{{ room }}_fan_speed #Variable here
      data:
        value: "33"
    - service: remote.send_command

          {%-elif "{{ room }}" == "b2" %}
          {{ 'b64:' }}
          {%-elif "{{ room }}" == "b3" %}
          {{ 'b64: ' }}
          {% endif %}

fan_66:
  alias: Fan (med)
  sequence:
    - service: input_text.set_value
      target:
        entity_id: input_select.{{ room }}_fan_speed #Variable here

          {%-elif "{{ room }}" == "b3" %}
          {{ 'b64: ' }}
          {% endif %}
fan_100:
  alias: Fan (max)
  sequence:
    - service: input_text.set_value
      target:
        entity_id: input_select.{{ room }}_fan_speed #Variable here
      data:
        value: "100"
    - service: remote.send_command
      data:
        entity_id: remote.rmpro_remote
        #Variables Below
        command: >

          {{ "b64:" }}
          {%-elif "{{ room }}" == "b2" %}
          {{ "b64:" }}
          {%-elif "{{ room }}" == "b3" %}
          {{ "b64:" }}
          {% endif %}

Any help is greatly appreciated!

You can’t nest templates. Fairly common mistake. Try this:

    - service: >
        {% if is_state('input_select.' ~ room ~ '_fan_speed', '33') %}
          script.fan_33
        {% elif is_state('input_select.' ~ room ~ '_fan_speed', '66') %}
          script.fan_66
        {% elif is_state('input_select.' ~ room ~ '_fan_speed', '100') %}
          script.fan_100
        {% endif %}
      data_template:
        room: "{{ room }}"

Thanks! One step closer (I hope) as I figured I was passing those variables incorrectly.

Still getting the following errors though:

Well, I don’t use remotes, so I’m not exactly sure what you need, but maybe at least:

    - service: remote.send_command
      data_template:
        entity_id: remote.rmpro_remote
        command: >
          {% if room == "b1"  %}
          b64:
          {% elif room == "b2" %}
          b64:
          {% elif room == "b3" %}
          b64:
          {% endif %}

Thank you SO much! Working perfectly now. Learning a lot about the formatting types of templating, even with the documentation provided by HA.

REALLY appreciate your help!

Are there only three options for each room’s input_select (33, 66, and 100) or are there more?

If there are only 33, 66, and 100 then the template can be reduced to:

  - service: "script.fan_{{ states('input_select.' ~ room ~ '_fan_speed') }}"

If there are other options then your existing template overlooks to take them into account and will produce no result when it encounters them (which will cause the service call to fail).

Really great suggestion :slight_smile: thanks will implement this also!

Why are you using three separate scripts, one for each of the three speeds, when just one script can do the job? In fact, it doesn’t need to be a separate script; the actions can be part of the fan_on script.
