lojack-api 0.7.2

An async Python client library for the LoJack API, designed for Home Assistant integrations.

lojack_api

An async Python client library for the Spireon LoJack API, designed for Home Assistant integrations.

Features

• Async-first design - Built with asyncio and aiohttp for non-blocking I/O
• No httpx dependency - Uses aiohttp to avoid version conflicts with Home Assistant
• Spireon LoJack API - Full support for the Spireon identity and services APIs
• Session management - Automatic token refresh and session resumption support
• Type hints - Full typing support with py.typed marker
• Clean device abstractions - Device and Vehicle wrappers with convenient methods

Installation

# From the repository
pip install .

# With development dependencies
pip install .[dev]

Quick Start

Basic Usage

import asyncio
from lojack_api import LoJackClient

async def main():
    # Create and authenticate (uses default Spireon URLs)
    async with await LoJackClient.create(
        "your_username",
        "your_password"
    ) as client:
        # List all devices/vehicles
        devices = await client.list_devices()

        for device in devices:
            print(f"Device: {device.name} ({device.id})")

            # Get current location
            location = await device.get_location()
            if location:
                print(f"  Location: {location.latitude}, {location.longitude}")

asyncio.run(main())

Session Resumption (for Home Assistant)

For Home Assistant integrations, you can persist authentication across restarts:

from lojack_api import LoJackClient, AuthArtifacts

# First time - login and save auth
async def initial_login(username, password):
    client = await LoJackClient.create(username, password)
    auth_data = client.export_auth().to_dict()
    # Save auth_data to Home Assistant storage
    await client.close()
    return auth_data

# Later - resume without re-entering password
async def resume_session(auth_data, username=None, password=None):
    auth = AuthArtifacts.from_dict(auth_data)
    # Pass credentials for auto-refresh if token expires
    client = await LoJackClient.from_auth(auth, username=username, password=password)
    return client

Using External aiohttp Session

For Home Assistant integrations, pass the shared session:

from aiohttp import ClientSession
from lojack_api import LoJackClient

async def setup(hass_session: ClientSession, username, password):
    client = await LoJackClient.create(
        username,
        password,
        session=hass_session  # Won't be closed when client closes
    )
    return client

Working with Vehicles

Vehicles have additional properties:

from lojack_api import Vehicle

async def vehicle_example(client):
    devices = await client.list_devices()

    for device in devices:
        if isinstance(device, Vehicle):
            print(f"Vehicle: {device.name}")
            print(f"  VIN: {device.vin}")
            print(f"  Make: {device.make} {device.model} ({device.year})")

Requesting Fresh Location Data

The Spireon REST API may return stale location data (30-76+ minutes old) because devices report periodically, not continuously. Two methods are available to request on-demand location updates:

Method Comparison

Method	Returns	Use Case
request_location_update()	bool	Fire-and-forget; scripts, simple polling
request_fresh_location()	datetime | None	Non-blocking with baseline; Home Assistant

request_location_update() -> bool

Sends a "locate" command to the device. Returns True if the command was accepted by the API. This is a fire-and-forget method - you must poll separately to detect when fresh data arrives.

# Simple usage - send command and poll manually
success = await device.request_location_update()
if success:
    await asyncio.sleep(30)  # Wait for device to respond
    location = await device.get_location(force=True)

request_fresh_location() -> datetime | None

Sends a "locate" command and returns the current location timestamp as a baseline for comparison. This is the recommended method for Home Assistant integrations because it's non-blocking and provides a reference point to detect when fresh data arrives.

from datetime import datetime, timezone

# In a service call or button handler
baseline_ts = await device.request_fresh_location()

# Later, in your DataUpdateCoordinator's _async_update_data:
location = await device.get_location(force=True)
if location and location.timestamp:
    # Check if we received fresh data since the locate command
    if baseline_ts and location.timestamp > baseline_ts:
        print("Fresh location received!")
    age = (datetime.now(timezone.utc) - location.timestamp).total_seconds()

Returns:

• datetime - The location timestamp before the locate command was sent
• None - If no prior location was available

Location History

# Get location history
async for location in device.get_history(limit=100):
    print(f"{location.timestamp}: {location.latitude}, {location.longitude}")

Troubleshooting Script

For debugging location freshness issues:

# Show current location ages
python scripts/poll_locations.py

# Request fresh location and monitor for updates
python scripts/poll_locations.py --locate

# Poll continuously every 30 seconds
python scripts/poll_locations.py --poll 30

Geofences

Geofences define circular areas that can trigger alerts when a device enters or exits the boundary.

# List all geofences for a device
geofences = await device.list_geofences()
for geofence in geofences:
    print(f"{geofence.name}: {geofence.latitude}, {geofence.longitude} (r={geofence.radius}m)")

# Create a geofence
geofence = await device.create_geofence(
    name="Home",
    latitude=32.8427,
    longitude=-97.0715,
    radius=100.0,  # meters
    address="123 Main St"
)

# Update a geofence
await device.update_geofence(
    geofence.id,
    name="Home Base",
    radius=150.0
)

# Delete a geofence
await device.delete_geofence(geofence.id)

Updating Device Information

Update device/vehicle metadata:

# Update device name
await device.update(name="My Tracker")

# For vehicles, update additional fields
await vehicle.update(
    name="Family Car",
    odometer=51000.0,
    color="Blue"
)

Maintenance Schedules (Vehicles)

Get maintenance schedule information for vehicles with a VIN:

# Get maintenance schedule
schedule = await vehicle.get_maintenance_schedule()
if schedule:
    print(f"Maintenance items for VIN {schedule.vin}:")
    for item in schedule.items:
        print(f"  {item.name}: {item.severity}")
        if item.mileage_due:
            print(f"    Due at: {item.mileage_due} miles")
        if item.action:
            print(f"    Action: {item.action}")

Repair Orders (Vehicles)

Get repair order history for vehicles:

# Get repair orders
orders = await vehicle.get_repair_orders()
for order in orders:
    print(f"Order {order.id}: {order.status}")
    if order.description:
        print(f"  Description: {order.description}")
    if order.total_amount:
        print(f"  Total: ${order.total_amount:.2f}")
    if order.open_date:
        print(f"  Opened: {order.open_date.isoformat()}")

User Information

Get information about the authenticated user and accounts:

# Get user info
user_info = await client.get_user_info()
if user_info:
    print(f"User: {user_info.get('email')}")

# Get accounts
accounts = await client.get_accounts()
print(f"Found {len(accounts)} account(s)")

Spireon API Details

The library uses the Spireon LoJack API:

• Identity Service: https://identity.spireon.com - For authentication
• Services API: https://services.spireon.com/v0/rest - For device/asset management

Authentication uses HTTP Basic Auth with the following headers:

• X-Nspire-Apptoken - Application token
• X-Nspire-Correlationid - Unique request ID
• X-Nspire-Usertoken - User token (after authentication)
