    - entity_id: sensor.purple_air_quality_aqi
      platform: state
    condition: []
    action:
    - service: zwave.set_config_parameter
      data_template:
        node_id: '20'
        parameter: '13'
        size: '4'
        value: '{{ state_attr(''sensor.purple_air_quality_aqi'', ''colorv'') }}'
