  Control HomeKit smart home accessories via HomeClaw MCP tools.
  Also includes reference data for accessory categories, characteristics, and value formats.
  This skill should be used when the user wants to:
  - Turn lights on or off, set brightness, or change color temperature
  - Lock or unlock doors
  - Set thermostat temperature or HVAC mode
  - Run a HomeKit scene like "Good Morning" or "Movie Time"
  - Check which devices are on, off, or unreachable
  - List accessories in a room or search by name
  - Check HomeClaw status or configure default home
  - Look up characteristic names, value types, ranges, or enum mappings
  Example triggers: "turn on the kitchen lights", "lock all doors",
  "set the thermostat to 72", "run the goodnight scene", "what lights are on",
  "list devices in the living room", "is HomeClaw running",
  "what characteristics does a thermostat have", "what are the lock state values"

# HomeKit Smart Home Control

HomeClaw exposes Apple HomeKit accessories via MCP tools. Use the `homekit_*` tools as the interface for all HomeKit operations.

## MCP Tools

The plugin registers 8 MCP tools.

| Tool | Description |
|------|-------------|
| `homekit_status` | Check bridge connectivity, home count, accessory count |
| `homekit_accessories` | List, get details, search, or control accessories |
| `homekit_rooms` | List rooms and their accessories |
| `homekit_scenes` | List, get details of, trigger, import, or delete scenes |
| `homekit_device_map` | Get LLM-optimized device map with semantic types, aliases, and zone hierarchy |
| `homekit_events` | Query recent HomeKit events (characteristic changes, scene triggers, control actions) |
| `homekit_automations` | Manage automations: list, create (inline actions or scene), delete, enable/disable |
| `homekit_webhook` | Manage webhook configuration: setup, test, reset circuit breaker, status |
| `homekit_config` | View or update bridge configuration |

### homekit_device_map

Returns a complete LLM-optimized device map organized by home/zone/room hierarchy. Each device includes:

| Field | Description |
|-------|-------------|
| `semantic_type` | Functional type: `lighting`, `climate`, `security`, `door_lock`, `window_covering`, `sensor`, `power`, `media`, `network`, `other` |
| `display_name` | Room-prefixed name for disambiguation (only when duplicates exist) |
| `aliases` | Auto-generated search terms like "kitchen light", "overhead in kitchen" |
| `controllable` | List of writable characteristics (e.g., `["power", "brightness"]`) |
| `state_summary` | One-line state: "on 75%", "72°F heating", "locked", "off", "unreachable" |
| `manufacturer` | Device manufacturer |
| `description` | Natural-language summary: "Lutron lighting (power, brightness), on 75%" |

**Use this tool first** when you need to understand the device landscape before controlling devices. It resolves name collisions and identifies switches that actually control lights.

### Semantic Type Reference

| Semantic Type | Maps From | Key Distinction |
|--------------|-----------|-----------------|
| `lighting` | lightbulbs | Devices with brightness/color control |
| `climate` | thermostats, fans, air purifiers | |
| `security` | doors, garage doors, cameras, doorbells, security systems | |
| `door_lock` | locks | |
| `window_covering` | windows, blinds, shades | |
| `sensor` | motion, contact, temperature, humidity sensors | |
| `power` | outlets, switches, programmable switches | In-wall switches get light aliases for search |
| `media` | speakers, televisions | |

### homekit_accessories

The main workhorse tool. Supports 4 actions via the `action` parameter:

| Action | Required Params | Description |
|--------|----------------|-------------|
| `list` | — | List all accessories. Optional: `room`. Returns enriched results with `semantic_type`, `display_name`, `manufacturer`, `zone`. |
| `get` | `accessory_id` | Get full detail with all characteristics |
| `search` | `query` | Search by name, room, category, semantic type, manufacturer, or aliases (e.g., "kitchen light" matches switches with lightbulb services). Optional: `category` |
| `control` | `accessory_id`, `characteristic`, `value` | Set a characteristic value |

### homekit_scenes

| Action | Required Params | Description |
|--------|----------------|-------------|
| `list` | — | List all scenes with name, type, and action count |
| `get` | `scene_id` | Get full scene detail including all actions (accessory, room, characteristic, target value) |
| `trigger` | `scene_id` | Execute a scene by name or UUID |

### homekit_events

| Param | Required | Description |
|-------|----------|-------------|
| `since` | No | Duration shorthand (`1h`, `30m`, `2d`) or ISO 8601 timestamp |
| `type` | No | Filter: `characteristic_change`, `scene_triggered`, `accessory_controlled`, `homes_updated` |
| `limit` | No | Max events to return (default: 50) |

### homekit_automations

| Action | Required Params | Description |
|--------|----------------|-------------|
| `list` | — | List all automations with event summaries and linked scenes |
| `get` | `id` | Detail view with events, action sets, and button info |
| `create` | `name`, `accessory_id`, plus `actions` or `scene_id` | Create a button-press automation (see below) |
| `delete` | `id` | Delete an automation |
| `enable` | `id` | Enable a disabled automation |
| `disable` | `id` | Disable an automation without deleting |

**Create parameters:**

| Param | Required | Description |
|-------|----------|-------------|
| `name` | Yes | Human-readable automation name |
| `accessory_id` | Yes | Button accessory UUID or name |
| `actions` | One of | Inline actions array (default, no visible scene). Each entry: `{accessory, property, value}` |
| `scene_id` | One of | Existing scene UUID or name to trigger |
| `press_type` | No | 0=single (default), 1=double, 2=long press |
| `service_index` | No | Button index for multi-button accessories (1 or 2) |
| `dry_run` | No | Preview without creating |

**Inline actions vs scenes:** Use `actions` for simple button-to-device mappings (creates a scene named after the automation). Use `scene_id` to trigger an existing shared scene. Note: Apple's Home app uses a private API for hidden automation-only action sets; inline actions created via HomeClaw will appear as visible scenes.

### homekit_config

| Action | Required Params | Description |
|--------|----------------|-------------|
| `get` | — | Show current configuration |
| `set` | at least one setting | Set `default_home_id`, `accessory_filter_mode`, `allowed_accessory_ids`, or `temperature_unit` |

## Common Workflows

### Turn on a light

1. Search for the light: `homekit_accessories` with `action: "search"`, `query: "kitchen"`
2. Identify the accessory UUID from the results
3. Turn it on: `homekit_accessories` with `action: "control"`, `accessory_id: "<uuid>"`, `characteristic: "power"`, `value: "true"`

### Set brightness

1. Find the light UUID (via search or list)
2. Set brightness: `homekit_accessories` with `action: "control"`, `accessory_id: "<uuid>"`, `characteristic: "brightness"`, `value: "50"`

### Lock all doors

1. Find all locks: `homekit_accessories` with `action: "search"`, `category: "lock"`
2. For each lock: `homekit_accessories` with `action: "control"`, `accessory_id: "<uuid>"`, `characteristic: "lock_target_state"`, `value: "locked"`

### Check temperature

1. Find thermostats: `homekit_accessories` with `action: "search"`, `category: "thermostat"`
2. Get details: `homekit_accessories` with `action: "get"`, `accessory_id: "<uuid>"`
3. Read the `current_temperature` characteristic from the response

### Set thermostat

1. Find the thermostat UUID (via search)
2. Set temperature: `homekit_accessories` with `action: "control"`, `accessory_id: "<uuid>"`, `characteristic: "target_temperature"`, `value: "72"`
3. Set mode: `homekit_accessories` with `action: "control"`, `accessory_id: "<uuid>"`, `characteristic: "target_heating_cooling"`, `value: "auto"`

### Run a scene

1. List scenes: `homekit_scenes` with `action: "list"`
2. Trigger: `homekit_scenes` with `action: "trigger"`, `scene_id: "Movie Time"`

### Inspect what a scene does

1. Get scene detail: `homekit_scenes` with `action: "get"`, `scene_id: "Good night"`
2. Response includes all actions: accessory name, room, characteristic, and target value

### List accessories by room

1. Filter by room: `homekit_accessories` with `action: "list"`, `room: "Living Room"`

### Switch active home

1. Configure: `homekit_config` with `action: "set"`, `default_home_id: "My Home"`

### Program a button (inline actions)

Creates a scene named after the automation and links it to the button press. **Always use UUIDs for target accessories** to avoid name collisions (many accessories share names like "Overhead" or "Blinds" across rooms).

1. Find the button: `homekit_accessories` with `action: "search"`, `query: "Office Button"`
2. Find target devices and note their UUIDs: `homekit_accessories` with `action: "list"`, `room: "Sarah's Bedroom"`
3. Check button services: `homekit_accessories` with `action: "get"`, `accessory_id: "<button-uuid>"` to see how many buttons and press types (`input_event` max: 0=single only, 2=single+double+long)
4. Create automation: `homekit_automations` with `action: "create"`, `name: "Room Open"`, `accessory_id: "<button-uuid>"`, `actions: [{accessory: "<light-uuid>", property: "power", value: "true"}, {accessory: "<blind-uuid>", property: "target_position", value: "100"}]`, `press_type: 0`, `service_index: 1`

### Program a button (with a named scene)

Use when the automation should trigger an existing scene:

1. Find the button and identify the scene
2. Create automation: `homekit_automations` with `action: "create"`, `name: "Button → Movie Time"`, `accessory_id: "<button-uuid>"`, `scene_id: "Movie Time"`, `press_type: 0`

### Button modes and service_index

Programmable switches (Aqara, Hue, etc.) may operate in different modes:

- **Fast mode**: Multiple buttons (e.g., Button 1 and Button 2), each single-press only. Fires instantly with no delay. Identified by `input_event` metadata `max: 0` on each service.
- **Multi-event mode**: One button with single, double, and long press. Adds ~300ms delay to detect press type. Identified by `input_event` metadata `max: 2`.

Use `--service-index` (CLI) or `service_index` (MCP) to target a specific button in fast mode. The mode itself is configured in the manufacturer's app (e.g., Aqara Home), not via HomeKit.

## Error Handling

| Error | Cause | Resolution |
|-------|-------|------------|
| "HomeClaw is not running" | App not launched or socket missing | Launch HomeClaw.app |
| "Connection failed" | Socket exists but app not responding | Restart the app |
| 0 homes / `ready: false` | Missing entitlement or iCloud not signed in | Check codesign entitlements and iCloud |
| "Accessory not found" | Wrong UUID or name | Use `search` to find the correct identifier |
| "Characteristic not writable" | Trying to set a read-only characteristic | Check the writable column in the characteristics tables below |
| Values show `"nil"` | Accessory is unreachable or bridge hasn't synced | Check `reachable` field; unreachable devices return `nil` for all state values |

## Configuration

Config file: `~/.config/homeclaw/config.json`

| Setting | Values | Default |
|---------|--------|---------|
| `default_home_id` | Home name or UUID | Primary home |
| `accessory_filter_mode` | `all`, `allowlist` | `all` |
| `allowed_accessory_ids` | Array of UUIDs | `[]` |
| `temperature_unit` | `fahrenheit`, `celsius`, `auto` | `auto` (uses system locale) |

Use `homekit_config` to view and modify settings. When `temperature_unit` changes, the characteristic cache is automatically invalidated and refreshed.
