Manual Installation

1. Download html-template-card.js to /www/custom_lovelace/html_template_card directory:

   mkdir -p www/custom_lovelace/html_template_card
   cd www/custom_lovelace/html_template_card/
   wget https://github.com/PiotrMachowski/Home-Assistant-Lovelace-HTML-Jinja2-Template-card/raw/master/dist/html-template-card.js

2. Add card to resources in ui-lovelace.yaml or in raw editor if you are using frontend UI editor:

   resources:
     - url: /local/custom_lovelace/html_template_card/html-template-card.js
       type: js

Hints

• To use mdi icon follow example: <ha-icon icon="mdi:weather-sunny"></ha-icon>.
• If content does not contain any template use flag do_not_parse: true to increase performance.
• If content does not contain entity id (e.g. because of loop) you have to provide it manually in entities to enable refresh of the card when it will be updated.
• If you want to enable refreshing for every change in HA use flag always_update: true. WARNING: this may cause heavy load of browser/HA. Best to use with flag do_not_parse: true.
• To check if your content is correct without changing configuration use Developer tools.
• To use this card as an element of picture-elements card use picture_elements_mode parameter.
