Simple scenes templating question

Configuration

Is it possible to template the snapshot_entities in scene.create?

I think not but I hope I am wrong.

e.g. (which don’t work hence the question)

service: scene.create
  data:
    scene_id: my_scene
      snapshot_entities: >
        {% for boolean in states.input_boolean if 'some_identifier' in boolean.object_id %}
          {{ boolean.entity_id }},
        {%- endfor %}

or

snapshot_entities: >
  {{ states | selectattr('domain', 'eq', 'input_boolean ')
            | selectattr('entity_id', 'search', 'some_identifier')
            | map(attribute = 'entity_id')
            | list }}

Yes, but your template needs to supply a list object (like your second option, added after I posted this), not build a text list.

I haven’t used scenes before, but just called:

service: scene.create
data:
  scene_id: test_scene_2
  snapshot_entities: >
    {{ states.sensor | selectattr('entity_id','contains','outside') |
    map(attribute='entity_id') |list }}

and that scene’s state summary looks like this:

<template TemplateState(<state scene.test_scene_2=unknown; entity_id=['sensor.outside_temperature', 'sensor.outside_illuminance', 'sensor.outside_temperature_2', 'sensor.outside_temperature_1'], friendly_name=test_scene_2 @ 2024-01-19T14:13:55.206038+00:00>)>

Thanks I’ll look at that but straightaway I learnt contains!
I didn’t know that was an option.
