How to pass templated entity_id to script field

Configuration

Hi all,

I’m having problems constructing a templated entity_id from the friendly name of a sprinkler switch to pass as a field variable to a script that turns on a quick irrigation run.

Here’s the script. As you can see there are two fields, zone and duration, which are required for the service call to the sprinkler switch.


alias: Start Quick Run
description: ""
fields:
  zone:
    name: Zone
    description: Zone to run
    required: true
    example: switch.back_east_fence
  duration:
    name: Duration
    description: Minutes to run
    required: true
    example: 10
sequence:
  - if:
      - condition: state
        entity_id: input_boolean.rachio_pause
        state: "on"
    then:
      - service: rachio.resume_watering
        data: {}
    else:
      - service: rachio.start_watering
        data:
          duration: "{{duration}}"
        target:
          entity_id: "{{zone}}"

Here’s the tap action section of the Mushroom Template card.

tap_action:
  action: call-service
  service: script.quick_run
  data:
    zone: '{{''switch.'' + states(''input_select.irrigation_zone'') | slugify}}'
    duration: '{{ states(''input_number.quick_run_minutes'') | int  }}'

Here’s the template in developer tools showing the expected output:

However, when called from the Mushroom Template card, I get the following error message: “Failed to call service script/quick_run. Template rendered invalid entity IDs: {{‘switch.’ + states(‘input_select.irrigation_zone’) | slugify}}”.

I’ve also tried this in the Mushroom card without luck. The editor sets the quotes or lack of.

zone: switch.{{states(‘input_select.irrigation_zone’) | slugify}}

I don’t want to use a selector in the script because it is used across several watering functions that aren’t all garden irrigation.

Any help appreciated.

Pretty likely templates aren’t allowed here. If you do not want to modify the original script, why not create a second script to pass the parameters, and call that from the mushroom card?

Yeah, see the end of the Actions documentation. You can’t use templates in them.

Thanks for the quick responses. It’s a pity on this limitation, but good to be aware. I’ll just reconfigure the scripts.
