Try this:
type: heading
icon: mdi:fan
heading: xxx
badges:
- type: entity
entity: sun.sun
- type: entity
entity: zone.home
card_mod:
style: |
.badges hui-heading-badge:nth-child(1) hui-entity-heading-badge {
--card-mod-icon: mdi:human;
}
.badges hui-heading-badge:nth-child(2) hui-entity-heading-badge {
--card-mod-icon: mdi:account;
}
.title ha-icon {
--card-mod-icon: mdi:car;
}
Just add jinja templates to do it conditionally.
