Template condition to check state for multiple entities?

Configuration
#1

Hi,

I need a template or state condition (in a script) that will test if any of the lights in a list is off. The list is supplied as a variable lights which may contain one or more lights.

Say I supply something like

variables:
  lights: 
    - light.one
    - light.two

Then I would to condition the script to run only if all the lights are off. So I need something like

condition: "{{is_state(lights,'off'}}"

that will work with a list of one or more lights. I can use some kind for loop, but how do I combine the True/Falses I get as output?

I tried something like the below, but it doesn’t work, even though it doesn’t give a syntax error:

conditions:>
{% for l in light %}
 - {{is_state(l,'on')}}
{%-endfor %}

Thanks for any help!

If you create a group containing all of the lights then the Template Condition to check if all are off is simply this:

condition: "{{ is_state('group.my_lights', 'off') }}"

If you, for some reason, don’t want to use a group but prefer to define them as a list in a variable, the template is a bit longer.

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

That’s great. Thanks a lot Taras.

The list is dynamically generated by some other sensors so I didn’t want to have a fixed group. A lot of new things to unpack in the template.

I tried this solution with a blueprint and I am always getting false. I will continue to research, but I have no solution at this moment.

This blueprint is my motion sensing automation. If the motion is detected, it turns the lights on to a color temperature based on the time of day. If the motion has been off for a while, it will turn the lights to half brightness for a bit (to warn people in the room) and then turn them off.
I am using the template statement to check if the lights are already off before telling them to go to half brightness.

mode: restart
max_exceeded: silent

trigger:
  platform: state
  entity_id: !input motion_entity

variables:
  lights_template: !input light_target

action:
  - if:
    - condition: template
      value_template: "{{trigger.to_state.state == 'on'}}"
    then:
    - service: light.turn_on
      data:
        brightness: 255
        color_temp: "{{states('sensor.v_timeofday_mireds')}}"
      target: !input light_target
    else:
      - if: # Check to see if all the lights are off
        - condition: template
          value_template: "{{ expand(lights_template) | selectattr('state', 'eq', 'on') | list | count > 0 }}"
        then:
          - delay: !input no_motion_wait
          - service: light.turn_on
            data:
              brightness: 127
            target: !input light_target
          - delay: !input auto_off_time
          - service: light.turn_off
            target: !input light_target

I found a solution. There is a duplicate post here with a lot of detail:

Here the solution is made better:

I was able to get my blueprint to work.
