Create many custom devices from a unique template?

Configuration Frontend
1

Hi,

Since I installed a Zigbee switch and a Hue bulb in many rooms, I had to create custom lights with the help of the template functionality.

These custom lights use the Zigbee switch to turn on/off and the Hue bulb to change brightness, color, etc.

I add this in configuration.yaml:

light: !include_dir_merge_list configs/light/

And I create a file in configs/light/ for each room.

Here is 2 of them as an example:

cp_light_bedroom.yaml:

platform: template
lights:
  composite_light_bedroom:
    friendly_name: "Bedroom light"
    level_template: "{{ state_attr('light.bedroom', 'brightness') | int }}"
    value_template: "{{ is_state('switch.bedroom', 'on') }}"
    temperature_template: "{{ state_attr('light.bedroom', 'color_temp') }}"
    color_template: "{{ state_attr('light.bedroom', 'hs_color')}}"
    turn_on:
      service: switch.turn_on
      data_template:
        entity_id: switch.bedroom
    turn_off:
      service: switch.turn_off
      data_template:
        entity_id: switch.bedroom
    set_level:
      service: light.turn_on
      data_template:
        entity_id: light.bedroom
        brightness: "{{ brightness }}"
    set_temperature:
      service: light.turn_on
      data_template:
        entity_id: light.bedroom
        color_temp: "{{ color_temp }}"
    set_color:
      service: light.turn_on
      data_template:
        hs_color:
          - "{{ h }}"
          - "{{ s }}"
        entity_id: light.bedroom

cp_light_kitchen.yaml:

platform: template
lights:
  composite_light_kitchen:
    friendly_name: "kitchen light"
    level_template: "{{ state_attr('light.kitchen', 'brightness') | int }}"
    value_template: "{{ is_state('switch.kitchen', 'on') }}"
    temperature_template: "{{ state_attr('light.kitchen', 'color_temp') }}"
    color_template: "{{ state_attr('light.kitchen', 'hs_color')}}"
    turn_on:
      service: switch.turn_on
      data_template:
        entity_id: switch.kitchen
    turn_off:
      service: switch.turn_off
      data_template:
        entity_id: switch.kitchen
    set_level:
      service: light.turn_on
      data_template:
        entity_id: light.kitchen
        brightness: "{{ brightness }}"
    set_temperature:
      service: light.turn_on
      data_template:
        entity_id: light.kitchen
        color_temp: "{{ color_temp }}"
    set_color:
      service: light.turn_on
      data_template:
        hs_color:
          - "{{ h }}"
          - "{{ s }}"
        entity_id: light.kitchen

As we can see, these two custom lights are exactly the same (except the room name of course) and this is the same for almost all my house lights.

I would like to know if I can create a single “custom light template” and then just add as many custom lights I want, all based on this “custom light template”.

Nobody knows if this is possible?

Hi there, I don’t know if this is possible, but I would just like to say thank you for showing me how to do this! :smile:
