This card is for Lovelace on Home Assistant.

We all use multiple times the same block of configuration across our lovelace configuration and we don't want to change the same things in a hundred places across our configuration each time we want to modify something.

declutterring-card to the rescue!! This card allows you to reuse multiple times the same configuration in your lovelace configuration to avoid repetition and supports variables and default values.

Configuration

Defining your templates

First, you need to define your templates.

The templates are defined in an object at the root of your lovelace configuration. This object needs to be named decluttering_templates.

This object needs to contains your templates declaration, each template has a name and can contain variables. A variable needs to be enclosed in double square brackets [[variable_name]]. It will later be replaced by a real value when you instanciate a card which uses this template. If a variable is alone on it's line, enclose it in single quotes: '[[variable_name]]'.

You can also define default values for your variables in the default object.

decluttering_templates:
  <template_name>
    default:  # This is optional
      - <variable_name>: <variable_value>
      - <variable_name>: <variable_value>
      [...]
    card:  # This is where you put your card config (it can be a card embedding other cards)
      type: custom:my-super-card
      [...]

Example in your lovelace-ui.yaml:

resources:
  - url: /local/decluttering-card.js
    type: module

decluttering_templates:
  my_first_template:     # This is the name of a template
    default:
      - icon: fire
    card:
      type: custom:button-card
      name: '[[name]]'
      icon: 'mdi:[[icon]]'

  my_second_template:    # This is the name of another template
    card:
      type: custom:vertical-stack-in-card
      cards:
        - type: horizontal-stack
          cards:
            - type: custom:button-card
              entity: '[[entity_1]]'
            - type: custom:button-card
              entity: '[[entity_2]]'
