Sending variables

[terse mirage]

An example passing variables from a custom button- card. ```yaml
type: custom:stack-in-card
mode: horizontal
card_mod:
style: |
ha-card {
--ha-card-background: none;
}
cards:

• type: entities
  entities:
  • entity: input_select.navigation_test_variable
    name: Room
    tap_action:
    action: none
    card_mod:
    style: |
    ha-card {
    --ha-card-background: none;
    border: none;
    }
• type: custom:button-card
  entity: null
  show_icon: false
  show_name: true
  name: Test
  show_state: false
  styles:
  card:
  - height: 100px
  - width: 100px
  variables:
  var_entity: |-
  [[[
  var e = states["input_select.navigation_test_variable"].state;
  if (e == "living-room" ) return 'light.living_room_lights';
  else if (e == "kitchen" ) return 'light.kitchen_lights';
  else if (e == "bedroom" ) return 'light.bedroom_lights';
  else return;
  ]]]
  tap_action:
  action: more-info
  entity: '[[[ return variables.var_entity; ]]]'
  double_tap_action:
  action: toggle
  entity: '[[[ return variables.var_entity; ]]]'
  hold_action:
  action: none
  card_mod:
  style: |
  ha-card {
  --ha-card-background: none;
  border: none;
  }

@terse mirage Thanks for this, still not positive or understanding how I can pass something coming from response_variable automation and use it within the card. I have not tried it but am wondering if that variable is globally available or only exists within the automation/script that is using it.

I think your variable has to be in a state or attribute for the card to use/see it. The example above is using the helper input_select.navigation_test_variable and its different states living-room, kitchen and bedroom. You would use your automation action to set the different states in the helper. And the card then uses that for whatever you are trying to do

[terse mirage]

Yeah. I meant to add that part but I forgot. Cards can see stuff in memory and have to rely on an entity. The automation can set the entity and then the card can use that information.
