For example:
type: entities
entities:
- type: custom:multiple-entity-row
entity: sun.sun
name: ''
entities: &ref_0
- entity: sensor.memory_free
name: free
- entity: sensor.memory_use
name: use
- entity: sensor.memory_total
name: total
- type: custom:multiple-entity-row
entity: sun.sun
name: ''
entities: *ref_0
card_mod:
style:
hui-generic-entity-row $: |
state-badge,
.info {
display: none;
}
.: |
hui-generic-entity-row {
justify-content: center;
}
- type: custom:multiple-entity-row
entity: sun.sun
name: ''
entities: *ref_0
card_mod:
style:
hui-generic-entity-row $: |
state-badge,
.info {
display: none;
}
.: |
hui-generic-entity-row {
justify-content: center;
}
.entities-row .entity {
margin-right: 12px !important;
margin-left: 12px !important;
