Feature Auto Select

Auto-select a tab

Automatically switch to a tab when something happens — e.g. jump to the Cameras tab when the doorbell rings, or to Alarm when it's triggered.

Per-tab key: auto_select — an entity id, or { entity, state }

type: custom:tabdeck-card
tabs:
  - name: Home
    card: { ... }
  - name: Cameras
    icon: mdi:cctv
    auto_select: binary_sensor.doorbell      # switch here when it becomes active
    card: { ... }
  - name: Alarm
    icon: mdi:shield-alert
    auto_select:
      entity: alarm_control_panel.home
      state: triggered                        # switch here on this exact state
    card: { ... }

Behaviour

• Edge-triggered: the switch happens only when the entity enters the target state (a fresh transition). You can navigate away afterwards and it won't yank you back until the next transition.
• No jump on load: the first state read only seeds the baseline, so opening the dashboard never force-switches.
• String form (auto_select: <entity>) fires when the entity becomes active — anything except off/0/false/unavailable/… (same rule as dot badges).
• Object form ({ entity, state }) fires on an exact state match.
• If the target tab is currently hidden by visibility, the switch is skipped.

auto_select is configured in YAML (not the visual editor).
