Dimmer script to only dimm lights that are on in a specific group not working

Configuration
1

I’m trying to use a script to only dimm lights that are on in a specific light group.
I use ControllerX to dim up and down with a Philips Hue dimmer.
script is called with:

up_short_release: 
      - service: script.light_dimmer_up
        data:
          lightgroup: group.dimmer_test

script:

light_dimmer_up:
  description: increase light level when dim up button is pressed
  sequence:
    - service: light.turn_on
      data_template:
        entity_id: >
          {{ expand( "{{ lightgroup }}" )| selectattr('state','eq','on') |
          map(attribute='entity_id') | list | join(', ') }}
      brightness_step_pct: 5

entity_id stays empty which results in the error:  not a valid value for dictionary value @ data['entity_id']
probably my syntax for the nested "lightgroup" variable isn't correct.

I can’t get it right :frowning:

Try changing the expand part to this:

{{ expand(lightgroup) | ....

And I think you can also leave out the join at the end as entity_id should accept a list.

Thank you!! That was it. Sometimes it’s dead simple, but couldn’t get it right.
Working like a charm now.

You can’t nest templates. It’s as simple as that.

Even if nesting was permitted, there’s still no need for it here because lightgroup is a variable and will be evaluated as a variable by the outer set of braces.
