Feature Enter Leave Actions

Tab-change actions (enter_action / leave_action)

Run a Home Assistant action whenever a tab becomes active (enter_action) or stops being active (leave_action). For example, open the Cameras tab to wake the cameras and leave it to put them back to sleep, or turn on a light when a room's tab is opened.

Per-tab keys: enter_action, leave_action (standard HA action objects)

type: custom:tabdeck-card
tabs:
  - name: Home
    card: { ... }
  - name: Cameras
    icon: mdi:cctv
    enter_action:
      action: perform-action
      perform_action: script.turn_on
      target: { entity_id: script.cameras_wake }
    leave_action:
      action: perform-action
      perform_action: script.turn_on
      target: { entity_id: script.cameras_sleep }
    card: { ... }

When they fire

• On every change of the active tab, from any source: tap, keyboard, swipe, auto_select, auto_rotate, idle_return, live remember: entity sync, or scroll-spy tracking.
• The old tab's leave_action runs first, then the new tab's enter_action.
• Not on initial load, and not when the already-active tab is tapped again.
• Each open copy of the dashboard runs its own actions. If a wall panel and a phone both show the deck, both fire, so make the actions safe to repeat (turning something on is safer than toggling it).

Supported actions

perform-action (what the editor's action picker writes), the legacy call-service, navigate, url, more-info, toggle, fire-dom-event. action: none counts as no action.

perform-action also works for tap_action, hold_action and badge_action. Before this release those silently ignored perform-action.

Both are available in the visual editor as Action when this tab is opened / Action when leaving this tab.
