AutoPi Integration for Home Assistant

This custom integration allows you to monitor your AutoPi vehicle tracking devices through Home Assistant. AutoPi combines OBD-II diagnostic data with GPS tracking to provide comprehensive vehicle monitoring and analytics.

Features

• 🚗 Vehicle Diagnostic Data

  • Engine parameters (RPM, coolant temperature, intake air temperature)
  • Fuel system status and consumption
  • Vehicle speed and odometer readings
  • Engine load and throttle position
  • Battery voltage and electrical system health
  • Diagnostic trouble codes (DTCs)
  • Emissions data (O2 sensor readings, catalyst efficiency)

• 📍 GPS Tracking & Location

  • Real-time vehicle location
  • Trip tracking and history
  • Geofencing capabilities
  • Speed monitoring and alerts
  • Route optimization data

• 🔄 Automatic Device Discovery - Automatically discovers all AutoPi devices in your account

• ⚙️ Flexible Configuration

  • Select specific vehicles to monitor or monitor all
  • Configurable update interval (default: 5 minutes for real-time vehicle data)
  • Auto-discovery can be enabled/disabled
  • Configurable discovery interval for new devices

• 📊 Real-time Updates - Fetches latest vehicle data at your configured interval

• 🏢 Multi-Vehicle Support - Monitors multiple vehicles across your AutoPi account

• 📱 Device-Centric Design - Each AutoPi device is registered as a device with its metrics as entities

Device and Entity Structure

This integration follows Home Assistant best practices:

• Devices: Each physical AutoPi device/vehicle is registered as a device in Home Assistant
• Entities: Each metric from a vehicle (speed, RPM, location, etc.) is a separate entity
• This allows you to:
  • Assign vehicles to different areas/zones
  • View all metrics from a vehicle in one place
  • Create automations based on specific vehicle conditions
  • Disable individual metrics you don't need

Prerequisites

• Home Assistant 2025.8.0 or newer
• AutoPi account with API access
• At least one AutoPi device installed in a vehicle

Installation

HACS Installation (Recommended)

1. Open HACS in your Home Assistant instance

3. Search for AutoPi in the default HACS integrations list
4. Install the integration
5. Restart Home Assistant

Manual Installation

1. Download the latest release from the releases page
2. Extract the custom_components/autopi folder to your Home Assistant's custom_components directory
3. Restart Home Assistant

Configuration

Getting your AutoPi API Key

1. Log in to your AutoPi Cloud
2. Navigate to your account settings
3. Go to "API Access" or "Developer Settings"
4. Generate a new API key or use an existing one

Adding the Integration

1. Go to Settings → Devices & Services in Home Assistant
2. Click "Add Integration"
3. Search for "AutoPi"
4. Enter your API key when prompted
5. Select your vehicles from the dropdown or leave empty to monitor all
6. Configure update interval and auto-discovery settings

Configuration Options

After setup, you can modify options by clicking "Configure" on the integration:

• Update Interval: How often to fetch vehicle data (minimum 60 seconds, default 300 seconds/5 minutes)
• Enable Auto-Discovery: Automatically discover and add new AutoPi devices
• Device Discovery Interval: How often to scan for new devices when auto-discovery is enabled

Entity Naming

Entities are created with the following naming pattern:

• sensor.{vehicle_name}_{data_type}
• binary_sensor.{vehicle_name}_{status_type}
• device_tracker.{vehicle_name}

For example:

• sensor.my_car_rpm
• sensor.my_car_coolant_temperature
• sensor.my_car_fuel_level
• device_tracker.my_car
• binary_sensor.my_car_engine_running

Attributes

Each sensor entity includes the following attributes:

• device_id: AutoPi device ID
• vehicle_id: Vehicle identifier
• last_updated: Timestamp of last data reading
• unit_system: Imperial or metric units

Examples

Automation Example

automation:
  - alias: "Low Fuel Alert"
    trigger:
      - platform: numeric_state
        entity_id: sensor.my_car_fuel_level
        below: 10
    action:
      - service: notify.mobile_app
        data:
          title: "Low Fuel Warning!"
          message: "Your car fuel level is below 10%"

  - alias: "Vehicle Started"
    trigger:
      - platform: state
        entity_id: binary_sensor.my_car_engine_running
        to: "on"
    action:
      - service: notify.mobile_app
        data:
          title: "Vehicle Started"
          message: "Your car engine has been started"

Dashboard Card Example

Debugging and Troubleshooting

Enable Debug Logging

To enable debug logging for this integration, add the following to your configuration.yaml:

logger:
  default: warning
  logs:
    custom_components.autopi: debug

This will show detailed information about:

• Device discovery
• API calls and responses
• Entity creation
• Update intervals
• Any errors or warnings

Common Issues

No devices found

• Verify your API key has access to your AutoPi account
• Check that you have AutoPi devices registered to your account
• Ensure the devices are online and reporting data
• Check debug logs for specific error messages

Authentication errors

• Regenerate your API key in the AutoPi Cloud
• Remove and re-add the integration with the new key

Missing vehicle data

• Some vehicles don't support all OBD-II parameters
• Check the vehicle compatibility in AutoPi Cloud
• Verify the device has been reporting data recently
• Enable debug logging to see what metrics are being received

Slow updates

• AutoPi devices may have varying update frequencies based on configuration
• Check your configured update interval in the integration options
• Note that more frequent polling won't get newer data if the devices haven't updated
