Hue dimmer to actually dim a light

Configuration
21

This is what I use, repeated double clicks cycle through a range of dimnesses.

- id: dblclick Dining
  alias: dbl click dining
  trigger:
    platform: event
    event_type: deconz_event
    event_data:
      id: double_switch_1
      event: 2004 
  action:
  - entity_id: light.dining_room
    data_template:
      brightness: > 
        {%  if is_state('light.dining_room','off') -%} 
        30
        {%- else -%}
          {% if ( states.light.dining_room.attributes.brightness + 75) > 255 -%}
           0
          {%- else -%}
           {{ states.light.dining_room.attributes.brightness + 75 }}
          {%- endif %}  
        {%- endif %}
    service: light.turn_on
