• Home Assistant >= 0.88 (last tested against 0.104.3)
• Thomas Lovén’s card-tools.js >= 2.0 (tested against 2.0, 49f34cd)

Card-tools is available as a plugin in the default community store

The standard Lovelace configuration for entities remains valid, with the exception of secondary_info.

secondary_info should be a string value, enclosed in double-quotes, which supports the parseTemplate syntax defined in card-tools.js. Per the documentation:

Two things are important:

- Template must start with [[<space> and end with <space>]]
- This is not in any way the same kind of template as used in the Home Assistant configuration

The templates are parsed by reading one step at a time from the `hass.states` object.
Thus, the first part must be an entity with domain and id, e.g. `light.bed_light`, `media_player.bedroom` etc.
Next is one of:

- entity_id
- state
- attributes.<attribute>
- last_changed
- last_updated

Also see details of the new conditional syntax at useful-markdown-card:

if

Syntax: [[ if(<condition>, <then>, <else>) ]] Simply put, if <condition> is satisfied, the template will be replaced with <then>, otherwise it will be replaced with <else>.

Both <then> and <else> can in turn be <template> expressions, and <else> can even be another if(!).

Conditions are in the form <left> <comparison> <right> where <left> and <right> are <template>, strings or numeric values.

<comparison> is one of ==, !=, <, >, <= or >=.
