comma.ai Home Assistant Integration

This custom integration allows you to monitor your comma.ai devices (EON, comma three, etc.) in Home Assistant.

Features

• Device Tracking: Track the GPS location of your comma.ai device on the map
• Sensor Entities: Monitor various device statistics and usage data (see below for full list)

Installation

1. Open HACS store
   • If you don't have HACS installed, follow these instructions
2. In the top right, click the three dots, and click "Custom Repositories"
3. Add https://github.com/bscholer/home-assistant-comma-ai, then close the modal
4. Search for comma.ai in the HACS store. Open comma.ai, and click "Download"
5. Restart Home Assistant
6. Go to Settings → Devices & Services → Add Integration
7. Search for "comma.ai"
8. Enter your JWT token (get it from jwt.comma.ai)

Configuration

The integration is configured through the UI. You only need to provide your JWT token from comma.ai.

Initial Setup

1. Get your JWT token from jwt.comma.ai
2. Add the integration in Settings → Devices & Services
3. Enter your JWT token

Updating Your JWT Token

JWT tokens expire after 90 days. To update your token:

1. Go to Settings → Devices & Services
2. Find the comma.ai integration
3. Click the ⋮ menu → "Reconfigure"
4. Enter your new JWT token from jwt.comma.ai
5. Click Submit

The integration will reload with the new token while preserving all your data and configuration.

Usage

Once configured, the integration will:

• Create a device for each comma.ai device in your account
• Add sensor entities for various device statistics
• Add a device tracker entity for GPS location tracking
• Update data every 60 seconds

Entities Created

For each comma.ai device, the following entities will be created:

Sensors

Device Information

• sensor.<device_name>_device_type - The type of device (e.g., "neo", "three")
• sensor.<device_name>_openpilot_version - The installed openpilot version
• sensor.<device_name>_prime_status - Whether the device has comma prime ("Yes" or "No")

Device Status

• sensor.<device_name>_last_ping - Last time the device communicated with comma servers (timestamp)
• sensor.<device_name>_last_location_time - Last location update timestamp

All-Time Statistics

• sensor.<device_name>_total_distance - Total distance driven with openpilot (km, auto-converts to miles)
• sensor.<device_name>_total_minutes - Total minutes driven with openpilot
• sensor.<device_name>_total_routes - Total number of routes driven with openpilot

Weekly Statistics

• sensor.<device_name>_week_distance - Distance driven this week (km, auto-converts to miles)
• sensor.<device_name>_week_minutes - Minutes driven this week
• sensor.<device_name>_week_routes - Number of routes driven this week

Device Tracker

• device_tracker.<device_name>_location - GPS location for map tracking

API Information

This integration uses the comma.ai public API documented at api.comma.ai.

Troubleshooting

If you encounter issues:

1. Check that your JWT token is valid at jwt.comma.ai
2. Check the Home Assistant logs for error messages
3. Ensure your device is online and connected to comma servers
