How to check the current on/off state? From an Areas Lights, in A Blueprint; using Selector>Target>Entity>Domain: Lights

So I am a bit of a newbie with home assistant, & in turn A virgin with templates, variable & Blueprints.

This is my first attempt at creating a Blueprint & so I started with A script that I have tried to convert to a Blueprint. But for the sake of simplicity, I can’t work out how to get the On/Off state of the lights in A room(area) to register? (from a Target Selector for lights) So with the great words from Pablo Picasso, i have obtained idea’s, concepts & code from other sources, but I just can’t get it to work.

I think it should be done with a variable & template like:

  input:
    target_lights:
      name: Targeted Lights
      description: The Lights this Script is Targeted at.
      selector:
        target:
          entity:
            domain: light

variables:
  lights: !input "target_lights"

- condition: 
  - "{{ expand(lights) | selectattr('state', '==', 'on') | list | count > 0 }}"

I’m assuming it is how I am referencing the variable or implementing the template,
but I have been banging my head for the last 24hrs on this & i’m stuck…

So Rumpelstiltskin, I offer you my first born blueprint to HAss:

blueprint:
  name: Another Light Blueprint-Script
  description: "My Default Light Blueprint-Script with my take on Profiles;\n\
  \ - Bright.     - (For Day time & Events, I need to be Awake; Bright eyed & bushy tailed).\n\
  \ - Dimmed      - (For after sunset & before sunrise when i'm (still) thinking about bed,\
  \ but I will want to be able to read the Funny pages).\n\
  \ - Night-Light - (For bed/sleep time, & you don't want to wake
  \ everyone else up, but you still want to see in an emergency; how to get to the Fridge)\n\
  \ - Colour-Loop -  (Was to be Aurora-Australis, but color-loop is easier to remember).\n\
  \ - Circadian   -  (For the rest of the house at night, & to get everyone in sync @ night with you).\n\
  \ - Adaptive    -  (This works really well with a bed/sleep input_boolean).\n\
  \ - Random      -  (A Sorely missed replacement to the light effect).\n\
  \ - Custom      -  (Utilise this when using scenes & applying custom colour effects).\n\
  \ - Flash       -  (works great in conjunction with Alarm Panel Automations).\n\n\
  \    - A PREREQUISITE of an input_select { Dropdown } with the desired above Profile/s (words) added is required. \n\
  \    - A PREREQUISITE of an input_boolean { Toggle } is reqired for Adaptive Profile Night-Light to work.\n\
  \    Go to Settings > Devices & Services > Helpers > Create Helper > { Dropdown } or { Toggle }.\n
  \   & I'm assuming you already have some Lights that you wanted to add.\n\n\
  \ Designed to be used with A Automation-Script, & that decides IF & WHEN too turn the Light/s On\
  \ (by calling this script) & Off (by any means you see fit)."

I hope someone out there can help me with this PLEASE???

Isn’t this working? Which error do you have?
Anything in the log?

I’m not solving the problem, but you can include the count test as a variable, then just test for that variable in the conditions, so you have a single point for editing this.

Like this:

variables:
  lights: !input "target_lights"
  lights_on: >-
    {{ expand(lights) 
    | selectattr('state', 'eq', 'on') 
    | list 
    | count > 0 }}

sequence:
  - choose:
      - conditions:
          - condition: state
            entity_id: !input profile_input_select
            state: Bright
        sequence:
          - if:
              - condition: 
                - "{{ lights_on }}"
            then:
              - servicee
...

You can also create variables for transition_change and transition_on and then reduce this whole block to:

          - service: light.turn_on
            data:
              color_temp: !input profile_bright_color_temp
              brightness: !input profile_bright_brightness
              transition: "{{ iif(lights_on, transition_change, transition on) }}"
            target:
              !input target_lights

Also:

This will allow users to select devices, which will probably break the expand you have later (I’m not sure if expand works for devices).

Maybe you could do like this to force selecting entities (which in other hands don’t have the same nice user experience):

    target_lights:
      name: Targeted Lights
      description: The Lights this Script is Targeted at.
      selector:
        entity:
          multiple: true
          domain: light

Sweet, thanks for that. That has heaps of useful stuff in it that helps heaps.
So once again thanks heaps for that EdwardTFNEdward Firmo But that doesn’t really answer my original Question.

For anyone else who finds this post. The problem with the above example is that the target selector; result (which can be found in the [Edit in yaml] of the saved script parameters). E.g.

  input:
    target_lights:
      area_id: office

But the template calculation is expecting A [entity_id] not A [area_id]. So the answer to the problem is in either how we handle the input data with the [Variables] or by using another {Selector}.

So if we format the variable input data according to if the user selected {Area, Device or Entity} in the blueprint parameter {target_lights>selector>target>entity>domain: lights}.

  input:
    target_lights:
      name: Targeted Lights
      description: The Lights this Script is Targeted at.
      selector:
        target:
          entity:
            domain: light

variables:
  lights: !input "target_lights"
  lights.area_id: "{{ expand (  area_entities ( lights.area_id ) ) | selectattr ( 'domain' , 'eq' , 'light' ) | selectattr ( 'state' , 'eq' , 'on' ) | list | count > 0 }}"
# for entities:
  lights.entity_id: "{{ is_state ( lights.entity_id , 'on' ) }}"
# for device:
  lights.device_id: "{{ is_state ( device_entities ( lights.device_id ) | first , 'on' ) }}"
# combining them all together so that it can handle missing data:
  lights_on: "{% if lights.device_id is defined %} {{ is_state ( device_entities ( lights.device_id ) | first , 'on' ) }} {% elif lights.entity_id is defined %} {{ is_state ( lights.entity_id , 'on' ) }} {% else %} {{ expand (  area_entities ( lights.area_id ) ) | selectattr ( 'domain' , 'eq' , 'light' ) | selectattr ( 'state' , 'eq' , 'on' ) | list | count > 0 }} {% endif %}"

- condition: 
  - "{{ lights_on }}"

Otherwise we choose another [Selector>Target] like [area] rather than [entity] & rewrite half of the script.
Please feel free to correct me if I’m wrong or if you have a better way of doing this?
Edit: :sob: There is a much better way of doing this: WTH! triumph How do you reference A Device’s state (On/Off/unavailable) for A Target Selector?
