What this skill does

# Home Assistant Skill

Control smart home devices via the Home Assistant REST API.

## Setup

Set environment variables:
- `HA_URL` — Your Home Assistant URL (e.g., `http://10.0.0.10:8123`)
- `HA_TOKEN` — Long-lived access token (create in HA → Profile → Long-Lived Access Tokens)

## Safety Rules

**Always confirm with the user before performing these actions:**
- **Locks** — locking or unlocking any lock
- **Alarm panels** — arming or disarming
- **Garage doors** — opening or closing (`cover.*` with `device_class: garage`)
- **Security automations** — disabling automations related to security or safety
- **Covers** — opening or closing covers that control physical access (gates, barriers)

Never act on security-sensitive devices without explicit user confirmation.

## Entity Discovery

### List all entities

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

### List entities by domain

```bash
# Switches
curl -s "$HA_URL/api/states" -H "Authorization: Bearer $HA_TOKEN" \
  | jq -r '.[] | select(.entity_id | startswith("switch.")) | "\(.entity_id): \(.state)"'

# Lights
curl -s "$HA_URL/api/states" -H "Authorization: Bearer $HA_TOKEN" \
  | jq -r '.[] | select(.entity_id | startswith("light.")) | "\(.entity_id): \(.state)"'

# Sensors
curl -s "$HA_URL/api/states" -H "Authorization: Bearer $HA_TOKEN" \
  | jq -r '.[] | select(.entity_id | startswith("sensor.")) | "\(.entity_id): \(.state) \(.attributes.unit_of_measurement // "")"'
```

Replace the domain prefix (`switch.`, `light.`, `sensor.`, etc.) to discover entities
in any domain.

### Get single entity state

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

### Area & Floor Discovery

Use the template API to query areas, floors, and labels.

```bash
# List all areas
curl -s -X POST "$HA_URL/api/template" \
  -H "Authorization: Bearer $HA_TOKEN" \
  -H "Content-Type: application/json" \
  -d '{"template": "{{ areas() }}"}'

# Entities in a specific area
curl -s -X POST "$HA_URL/api/template" \
  -H "Authorization: Bearer $HA_TOKEN" \
  -H "Content-Type: application/json" \
  -d '{"template": "{{ area_entities(\"kitchen\") }}"}'

# Only lights in an area
curl -s -X POST "$HA_URL/api/template" \
  -H "Authorization: Bearer $HA_TOKEN" \
  -H "Content-Type: application/json" \
  -d '{"template": "{{ area_entities(\"kitchen\") | select(\"match\", \"light.\") | list }}"}'

# Find which area an entity belongs to
curl -s -X POST "$HA_URL/api/template" \
  -H "Authorization: Bearer $HA_TOKEN" \
  -H "Content-Type: application/json" \
  -d '{"template": "{{ area_name(\"light.kitchen\") }}"}'

# List all floors and their areas
curl -s -X POST "$HA_URL/api/template" \
  -H "Authorization: Bearer $HA_TOKEN" \
  -H "Content-Type: application/json" \
  -d '{"template": "{% for floor in floors() %}{{ floor }}: {{ floor_areas(floor) }}\n{% endfor %}"}'
