# 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)

## Quick Reference

### List Entities

```bash
curl -s -H "Authorization: Bearer $HA_TOKEN" "$HA_URL/api/states" | jq '.[].entity_id'
```

### Get Entity State

```bash
curl -s -H "Authorization: Bearer $HA_TOKEN" "$HA_URL/api/states/light.living_room"
```

### Control Devices

```bash
# Turn on
curl -X POST -H "Authorization: Bearer $HA_TOKEN" -H "Content-Type: application/json" \
  "$HA_URL/api/services/light/turn_on" -d '{"entity_id": "light.living_room"}'

# Turn off
curl -X POST -H "Authorization: Bearer $HA_TOKEN" -H "Content-Type: application/json" \
  "$HA_URL/api/services/light/turn_off" -d '{"entity_id": "light.living_room"}'

# Set brightness (0-255)
curl -X POST -H "Authorization: Bearer $HA_TOKEN" -H "Content-Type: application/json" \
  "$HA_URL/api/services/light/turn_on" -d '{"entity_id": "light.living_room", "brightness": 128}'
```

### Run Scripts & Automations

```bash
# Trigger script
curl -X POST -H "Authorization: Bearer $HA_TOKEN" "$HA_URL/api/services/script/turn_on" \
  -H "Content-Type: application/json" -d '{"entity_id": "script.goodnight"}'

# Trigger automation
curl -X POST -H "Authorization: Bearer $HA_TOKEN" "$HA_URL/api/services/automation/trigger" \
  -H "Content-Type: application/json" -d '{"entity_id": "automation.motion_lights"}'
```

### Activate Scenes

```bash
curl -X POST -H "Authorization: Bearer $HA_TOKEN" "$HA_URL/api/services/scene/turn_on" \
  -H "Content-Type: application/json" -d '{"entity_id": "scene.movie_night"}'
```

## 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.

## CLI Wrapper

The `scripts/ha.sh` CLI provides easy access to all HA functions:

```bash
# Test connection
ha.sh info

# List entities
ha.sh list all          # all entities
ha.sh list lights       # just lights
ha.sh list switch       # just switches

# Search entities
ha.sh search kitchen    # find entities by name

# Get/set state
ha.sh state light.living_room
ha.sh states light.living_room   # full details with attributes
ha.sh on light.living_room
ha.sh on light.living_room 200   # with brightness (0-255)
ha.sh off light.living_room
ha.sh toggle switch.fan

# Scenes & scripts
ha.sh scene movie_night
ha.sh script goodnight

# Climate
ha.sh climate climate.thermostat 22

# Call any service
ha.sh call light turn_on '{"entity_id":"light.room","brightness":200}'
```

## Troubleshooting

- **401 Unauthorized**: Token expired or invalid. Generate a new one.
- **Connection refused**: Check HA_URL, ensure HA is running and accessible.
- **Entity not found**: List entities to find the correct entity_id.
