Markdown card

The Markdown card is used to render Markdown.

The renderer uses Marked.js, which supports several specifications of Markdown, including CommonMark, GitHub Flavored Markdown (GFM) and markdown.pl.

To add the markdown card to your user interface:

  1. In the top right of the screen, select the edit button.
    • If this is your first time editing a dashboard, the Edit dashboard dialog appears.
      • By editing the dashboard, you are taking over control of this dashboard.
      • This means that it is no longer automatically updated when new dashboard elements become available.
      • Once you’ve taken control, you can’t get this specific dashboard back to update automatically. However, you can create a new default dashboard.
      • To continue, in the dialog, select the three dots menu, then select Take control.
  2. Add a card to your dashboard.

YAML configuration

The following YAML options are available when you use YAML mode or just prefer to use YAML in the code editor in the UI.

Configuration Variables

Looking for your configuration file?
type string Required
markdown
content string Required

Content to render as Markdown. May contain templates.

title string (Optional, default: none)

The card title.

card_size integer (Optional, default: none)

The algorithm for placing cards aesthetically may have problems with the Markdown card if it contains templates. You can use this value to help it estimate the height of the card in units of 50 pixels (approximately 3 lines of text in default size). (e.g., 4)

entity_id string | list (Optional, default: none)

A list of entity IDs so a template in content: only reacts to the state changes of these entities. This can be used if the automatic analysis fails to find all relevant entities.

theme string (Optional)

Override the used theme for this card with any loaded theme. For more information about themes, see the frontend documentation.

show_empty boolean (Optional, default: true)

By default, an empty card will still be shown (resulting in a small empty box). Setting this to false hides that empty card instead.

Example 

type: markdown
content: >
  ## Dashboards

  Starting with Home Assistant 0.72, we're experimenting with a new way of defining your interface.

Template variables

A special template variable - config is set up for the content of the card. It contains the configuration of the card.

For example:

type: entity-filter
entities:
  - light.bed_light
  - light.ceiling_lights
  - light.kitchen_lights
state_filter:
  - 'on'
card:
  type: markdown
  content: |
    The lights that are on are:
    {% for l in config.entities %}
      - {{ l.entity }}
    {%- endfor %}

    And the door is {% if is_state('binary_sensor.door', 'on') %} open {% else %} closed {% endif %}.

A special template variable - user is set up for the content of the card. It contains the currently logged in user.

For example:

type: markdown
content: |
  Hello, {{user}}

Icons

You can use Material Design Icons icons in the content of the card.

For example:

type: markdown
content: |
  <ha-icon icon="mdi:home-assistant"></ha-icon>

ha-alert

You can also use our `ha-alert` component in the Markdown card.

Example:

  <ha-alert alert-type="info">This is an info alert — check it out!</ha-alert>
  <ha-alert alert-type="success">This is a success alert — check it out!</ha-alert>
  <ha-alert title="Test alert">This is an alert with a title</ha-alert>

ha-qr-code

You can also create QR-Codes in the Markdown card.

  <ha-qr-code data='hallo' scale="6" margin="0"
