Manual Installation

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

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

    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.
