Using templates in Lovelace and custom auto-entities card in Home Assistant Container

Configuration Frontend
1

I am running HA Container 2025.10.1 and trying to use templates in Lovelace. In my raw editor I have a very simple card:

                cards:
                  - type: entities
                    entities:
                      - entity: sun.sun
                      - entity: sensor.sunrise_time
                      - entity: sensor.sunset_time

The card renders perfectly happily. This is a test card to just check if template rendering works.

If I change the code to:

                cards:
                  - type: entities
                    entities:
                      - entity: sun.sun
                        name: "{{ 'Test' }}"
                      - entity: sensor.sunrise_time
                      - entity: sensor.sunset_time

I was hoping the text displayed for the sun would turn to Test. Instead it renders as {{ ā€˜Testā€™ }}

Iā€™m pulling my hair out here trying to understand whatā€™s not working. Iā€™ve searched for hours and can find nothing. Or are Jinja2 templates not allowed in the Lovelace?

Only one stock card - Markdown - accepts jinja templates for ā€œcontentā€ option. There are custom cards which can work with templates.

Thanks. I didnā€™t realise it was card specific. The one I am trying to use it on the custom auto-entities from HACS (GitHub - thomasloven/lovelace-auto-entities: šŸ”¹Automatically populate the entities-list of lovelace cards) which looks like it should accept this according to the documentation. In that I have:

      - type: custom:auto-entities
        card:
          - type: entities
            title: Zigbee Devices (Last Seen)
        filter:
          include:
            - entity_id: '*last_seen'
              options:
                name: '{{ "Test" }}'
                icon: mdi:zigbee
          exclude:
            - state: unavailable
        sort:
          method: state
          reverse: true

This just renders {{ ā€œTestā€ }} as well.

Templates are only allowed for ā€œfilter::templateā€ option, not where you tried. You will need to build a list in that ā€œtemplateā€ option, check examples in the main a-e thread.

Thanks very much for clarifying. My first foray into Jinja2 in HAā€¦

The simplest example:

type: custom:auto-entities
card:
  type: entities
filter:
  template: >-
    {% for entity in states.zone|selectattr('entity_id','search','home') -%}
      {{
        {
          'entity': entity.entity_id,
          'secondary_info': 'last-changed',
          'name': states('sun.sun')
        }
      }},
    {%- endfor %}

which shows one line (define own any filtering criteria).
