what is the correct syntax for the following task?
My attempts return an error.

also tried to pack the parameters in one line. All without success.

    - service: light.turn_on
      data_template: >-
        {% if is_state('sun.sun', 'above_horizon') %}
          entity_id: light.hue_ambiance_spot_1
          transition: 3
          brightness: 160
          color_temp: 180
        {% else %}
          entity_id: light.hue_ambiance_spot_1
          brightness: 200
          color_temp: 100
        {% endif %}

You can only template the value of a key: value pair. You have both in your template. For three keys you need three templates.

Thank you for your response.
I thought it would somehow be possible to pack groups of parameters into one template rule.
