Blueprint: Help with variables usage via "input:" and "action choose"

Hello,

I am trying to build more functionalitites in a blueprint, but I am struggling with two approaches.

  1. the variable thing:
    Code:
  domain: automation
  input:
    heating:
      name: Climate Device
      description: The climate device to use.
      selector:
        entity:
          domain: climate
    temp_sensor:
      name: Temperature Sensor
      description: Temperature Sensor to check.
      selector:
        entity:
          domain: sensor
          device_class: temperature
    window_sensor_1:
      name: Door or Window Sensor
      description: Check if window or door is open
      selector:
        entity:
          domain: binary_sensor
          device_class: opening
...
action:
- choose:
...
    - service: climate.set_temperature
      data:
        entity_id: !input 'heating'
        hvac_mode: >-
            {% if states('WHAT TO PUT IN HERE TO USE window_sensor_1') == 'on' %} off
            {% else %} heat
            {% endif %}
        temperature: '{{ set_temp }}'
  1. Option with action choose.
    Code:
blueprint:
  name: Heating Control and Window Sensor
  description: Control your heating with options for group home, if temp is below
    a specific value, set temp, and heating between specific times.
  domain: automation
  input:
    heating:
      name: Climate Device
      description: The climate device to use.
      selector:
        entity:
          domain: climate
    temp_sensor:
      name: Temperature Sensor
      description: Temperature Sensor to check.
      selector:
        entity:
          domain: sensor
          device_class: temperature
    window_sensor_1:
      name: Door or Window Sensor
      description: Check if window or door is open
      selector:
        entity:
          domain: binary_sensor
          device_class: opening
    groupname:
      name: Person Group
      description: The group of people that have to be home.
      default: []
      selector:
        entity:
          domain: group
    group_presence:
      name: Group Presence
      description: Heat only if Person of Group was present in a given amount of time
      default: 07:30:00
      selector:
        time: {}
    min_temp:
      name: Minimum Temp
      description: If temperature is below this value and someone is home, It turns
        heating on.
      default: 15
      selector:
        number:
          min: 11.0
          max: 25.0
          step: 0.1
          mode: slider
    set_temp:
      name: Temperature Target
      description: If the heating turns on, It heats to this target temperature.
      default: 20
      selector:
        number:
          min: 14.0
          max: 25.0
          step: 0.1
          mode: slider
    energy_temp:
      name: Energy Saving Temperature
      description: When away, keep the Energy Saving Temperature 
      default: 17
      selector:
        number:
          min: 14.0
          max: 25.0
          step: 0.1
          mode: slider
    time_after:
      name: Time After
      description: After this time the heating turns on, so it's warm in the morning
      default: 07:30:00
      selector:
        time: {}
    time_before:
      name: Time Before
      description: After this time the heating turns off, This to prevent the heating
        is on in the middle of the night
      default: '21:30:00'
      selector:
        time: {}
  source_url: https://gist.github.com/f45tb00t/eab416909ff6d125d7f3c6170ab017a9
variables:
  set_temp: !input 'set_temp'
  energy_temp: !input 'energy_temp'

trigger:
- platform: homeassistant
  event: start
- platform: event
  event_type: automation_reloaded
- platform: time_pattern
  minutes: /1
action:
- choose:
  - conditions:
    - condition: state
      entity_id: !input 'window_sensor_1'
      state: on
    sequence:
    - service: climate.set_temperature
      data:
        entity_id: !input 'heating'
        hvac_mode: off

  - conditions:
    - condition: numeric_state
      entity_id: !input 'temp_sensor'

    - condition: not
      conditions:

        entity_id: !input 'groupname'
        for: !input 'group_presence'
        state: not_home
    sequence:
    - service: climate.set_preset_mode
      data:
        entity_id: !input 'heating'
        preset_mode: none
    - service: climate.set_temperature
      data:
        entity_id: !input 'heating'
        hvac_mode: heat
        temperature: '{{ set_temp }}'

  default:
  - service: climate.set_preset_mode
    data:
      entity_id: !input 'heating'
      preset_mode: Energy heat
  - service: climate.set_temperature
    data:
      entity_id: !input 'heating'
      temperature: '{{ energy_temp }}'
mode: single

Weird is, that I can add an automation, but the automation is not visible within the automation menue, but can be found in automation.yaml
The error I get is:

2021-09-01 11:31:21 ERROR (MainThread) [homeassistant.components.automation] Blueprint Heating Control and Window Sensor generated invalid automation with inputs OrderedDict([(‘heating’, ‘climate.heizung_wohnzimmer’), (‘temp_sensor’, ‘sensor.lumi_lumi_weather_temperature_wohnzimmer’), (‘window_sensor_1’, ‘binary_sensor.lumi_lumi_sensor_magnet_aq2_acd2e401_on_off_wohnzimmer_velux’), (‘groupname’, ‘group.awesome_people’)]): expected str for dictionary value @ data[‘action’][0][‘choose’][0][‘conditions’][0][‘state’]. Got None

It would be great if anyone has an idea how to fix option 1 or 2.

Cheers

To answer my own question:

variables:
  window_sensor_1: !input 'window_sensor_1'
...
    - service: climate.set_temperature
      data:
        entity_id: !input 'heating'
        hvac_mode: >-
            {% if states(window_sensor_1) == 'on' %} off
            {% else %} heat
            {% endif %}
  1. no idea…
