Return light to previous state?

Configuration
, , , ,
#1

Hi, when I activate my button
( input_boolean.tema_romantico ) I would like automation to start taking a snapshot of the following lights:
light.yeelight_colorc_0x1b0ffc9a
light.yeelight_colorc_0x18906fb6
light.yeelight_colorc_0x189042ff
light.faretti_camera_da_bed
light.suprema_smart_controller_rgbww_4
to then start a script already created that changes the brightness and color of the lights in question. When the input_boolean.tema_romantico is turned off I would like it to load the snapshot made previously.

I tried to search the internet for how to do it, but I only found this piece of code that could help me but I don’t know how to complete it:

  alias: Camera da letto snapshot
  description: ''
  trigger:
  - entity_id: input_boolean.tema_romantico
    from: 'off'
    platform: state
    to: 'on'
  condition: []
  action:
  - data:
      snapshot_entities: light.yeelight_colorc_0x1b0ffc9a light.yeelight_colorc_0x18906fb6
        light.yeelight_colorc_0x189042ff light.faretti_camera_da_letto light.suprema_smart_controller_rgbww_4
    service: scene.create
  - service: script.1643407098523
  - delay: 00:00:04

There’s an example in the Scene Documentation.

When the input_boolean is turned on, the automation creates a snapshot scene of the five lights, named scene.lights_before, and then executes your script.

When the input_boolean is turned off, the automation turns on scene.lights_before thereby restoring the previous state of the five lights.

  alias: Camera da letto snapshot
  description: ''
  trigger:
  - platform: state
    entity_id: input_boolean.tema_romantico
  condition: []
  action:
  - choose:
    - conditions: "{{ trigger.to_state.state == 'on' }}"
      sequence:
      - service: scene.create
        data:
          scene_id: lights_before
          snapshot_entities:
          - light.yeelight_colorc_0x1b0ffc9a
          - light.yeelight_colorc_0x18906fb6
          - light.yeelight_colorc_0x189042ff
          - light.faretti_camera_da_letto
          - light.suprema_smart_controller_rgbww_4
      - service: script.1643407098523
    default:
    - service: scene.turn_on
      target:
        entity_id: scene.lights_before

EDIT

Correction. Replace template’s outer single-quotes with double-quotes.

When I enter " ‘{{ trigger.to_state.state == ‘on’ }}’ " in automations.yaml show me an error, says:

That’s due a small but significant error I made in the original example. Replace the template’s outer single-quotes with double-quotes (I have already corrected the example posted above).

Change this:

'{{ trigger.to_state.state == 'on' }}'

to this:

"{{ trigger.to_state.state == 'on' }}"

The rule is that the template’s outer quotes must not be identical to its inner quotes.

For some strange reason it doesn’t work, I keep putting the input_boolean on but nothing …

What’s wrong?

  tema_romantico:

If you notice the automation is slightly different because when I opened it in the graphical interface it always appeared to me “Save”, clicking on it added this line of code:

- conditions:
      - condition: template
        value_template: '{{ trigger.to_state.state == ''on'' }}'

This is your line:

- conditions: "{{ trigger.to_state.state == 'on' }}"

obviously I tried them both but it doesn’t work anyway :frowning:

Your version is missing this line:

          scene_id: lights_before

in the service call to create the scene:

      - service: scene.create
        data:
          scene_id: lights_before
          snapshot_entities:
          - light.yeelight_colorc_0x1b0ffc9a
          - light.yeelight_colorc_0x18906fb6
          - light.yeelight_colorc_0x189042ff
          - light.faretti_camera_da_letto
          - light.suprema_smart_controller_rgbww_4
