Feature Conditional Default

Conditional default tab

Pick which tab opens first based on the current state — e.g. open the Guest tab when guest mode is on, otherwise the normal home tab.

Per-tab key: default_if — a list of conditions (same format as visibility)

type: custom:tabdeck-card
default_tab: Home          # fallback when nothing matches
tabs:
  - name: Home
    card: { ... }
  - name: Guest
    default_if:
      - condition: state
        entity: input_boolean.guest_mode
        state: "on"
    card: { ... }

Behaviour

• On load, the first tab (in order) whose default_if conditions all pass becomes the starting tab.
• If none match, the normal default_tab is used.
• A remembered selection (remember) still wins over default_if.
• default_if is evaluated at first paint, so use synchronous conditions: state, numeric_state, screen, time, user, and and/or/not groups. Template conditions may not have resolved yet on the very first render and aren't reliable here.
• Configured in YAML.

In the visual editor, use the tab's Default when condition builder. See The Visual Editor.
