Blueprint: use area name as variable for entity name

Configuration Blueprints
1

Hi,

I’m trying to create my first blueprint.It should automate the behaviour, what to do if I open a windows in a specific room.

I did group my window sensors.

How do I do this right?

blueprint:
        name: Heizung-Fenster-Steuerung
        domain: automation
        input:
            area:
                name: Raum
                selector:
                    area:
    
        description: ""
    variables:
        area: !input 'area'
        trigger:
          - platform: state
            entity_id:
              - binary_sensor.raum_{{area}}
            for:
              hours: 0
              minutes: 0
              seconds: 10
        condition:
          - condition: not
            conditions:
              - condition: state
                entity_id: switch.schedule_heizperiode_aus
                state: "on"
                enabled: true
        action:
          - choose:
              - conditions:
                  - condition: state
                    entity_id: binary_sensor.raum_{{area}}
                    state: "on"
                sequence:
                  - service: scene.create
                    data:
                      snapshot_entities:
                        - switch.schedule_{{area}}
                        - climate.thermostat_{{area}}
                      scene_id: temp_{{area}}
                  - repeat:
                      sequence:
                        - service: climate.turn_off
                          data: {}
                          target:
                            entity_id: climate.thermostat_{{area}}
                      until:
                        - condition: state
                          entity_id: climate.thermostat_{{area}}
                          state: "off"
              - conditions:
                  - condition: state
                    entity_id: binary_sensor.raum_{{area}}
                    state: "off"
                sequence:
                  - repeat:
                      sequence:
                        - service: climate.turn_on
                          data: {}
                          target:
                            entity_id: climate.thermostat_{{area}}
                      until:
                        - condition: not
                          conditions:
                            - condition: state
                              entity_id: climate.thermostat_{{area}}
                              state: "off"
                  - delay:
                      hours: 0
                      minutes: 0
                      seconds: 10
                      milliseconds: 0
                  - service: scene.turn_on
                    target:
                      entity_id: scene.temp_{{area}}
                    metadata: {}

Variables are not rendered until after the trigger, so there is nothing in area until after the trigger, meaning no trigger…

You need to use trigger_variables , which are limited, when the data has to be there for the trigger.

I got a working solution:
