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., "ThinkFleetBot")
4. Copy the token immediately (shown only once)

Inbound Webhooks (HA → ThinkFleetBot)

To receive events from Home Assistant automations:

1. Create HA Automation with Webhook Action

# In HA automation
action:
  - service: rest_command.notify_thinkfleetbot
    data:
      event: motion_detected
      area: living_room

2. Define REST Command in HA

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

3. Handle in ThinkFleetBot

ThinkFleetBot 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:

# 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.
