# Home Assistant

Control your smart home via Home Assistant's REST API and webhooks.

## Setup

### Option 1: Config File (Recommended)

Create `~/.config/home-assistant/config.json`:
```json
{
  "url": "https://your-ha-instance.duckdns.org",
  "token": "your-long-lived-access-token"
}
```

### Option 2: Environment Variables

```bash
export HA_URL="http://homeassistant.local:8123"
export HA_TOKEN="your-long-lived-access-token"
```

### Getting a Long-Lived Access Token

1. Open Home Assistant → Profile (bottom left)
2. Scroll to "Long-Lived Access Tokens"
3. Click "Create Token", name it (e.g., "Clawdbot")
4. Copy the token immediately (shown only once)

## Inbound Webhooks (HA → Clawdbot)

To receive events from Home Assistant automations:

### 1. Create HA Automation with Webhook Action

```yaml
# In HA automation
action:
  - service: rest_command.notify_clawdbot
    data:
      event: motion_detected
      area: living_room
```

### 2. Define REST Command in HA

```yaml
# configuration.yaml
rest_command:
  notify_clawdbot:
    url: "https://your-clawdbot-url/webhook/home-assistant"
    method: POST
    headers:
      Authorization: "Bearer {{ webhook_secret }}"
      Content-Type: "application/json"
    payload: '{"event": "{{ event }}", "area": "{{ area }}"}'
```

### 3. Handle in Clawdbot

Clawdbot receives the webhook and can notify you or take action based on the event.
