Installation

Using uv (recommended)

uv add trinity-connect-client

Using pip

pip install trinity-connect-client

From source

uv add git+https://github.com/trinity-telecomms/connect-py-client@v0.2.0

Quick Start

from trinity_connect_client import ConnectClient
from trinity_connect_client.exceptions import ResourceNotFoundError, UnauthorisedError

# Initialize the client
client = ConnectClient(
  api_version="v4",
  base_url="https://capi.trintel.co.za",
  token="your-service-account-token"
)

# Get a device by ID (returns dict)
try:
    device = client.devices.get(device_id=123)
    print(f"Device name: {device['name']}")
except ResourceNotFoundError:
    print("Device not found")
except UnauthorisedError:
    print("Access denied")

Using Response Models

The library provides type-safe dataclass models for API responses:

from trinity_connect_client import ConnectClient, Device, Company, Folder

client = ConnectClient(
    api_version="v4",
    base_url="https://capi.trintel.co.za",
    token="your-service-account-token"
)

# Get device as dict, then convert to model for type safety
device_dict = client.devices.get(device_id=123)
device = Device.from_dict(device_dict)

# Now you have full type hints and IDE autocomplete
print(f"Device: {device.name}")
print(f"UID: {device.uid}")
print(f"Status: {device.status}")

# Works with all response types
company_dict = client.orgs.get(company_id=1)
company = Company.from_dict(company_dict)

folders_list = client.orgs.get_folders(company_id=1)
folders = [Folder.from_dict(f) for f in folders_list]

Available Models:

• Device - Device information
• Company - Company/organization information
• Folder - Folder information
• DeviceData - Device telemetry data
• DeviceEvent - Device events
• DeviceCommand - Device commands

Configuration

Environment Variables

You can set your service account token via environment variables:

export CONNECT_API_TOKEN="your-service-account-token"
export CONNECT_API_BASE_URL="https://capi.trintel.co.za"

import os
from trinity_connect_client import ConnectClient

client = ConnectClient(
    api_version="v4",
    base_url=os.getenv("CONNECT_API_BASE_URL"),
    token=os.getenv("CONNECT_API_TOKEN")
)

Migration from v0.1.x to v0.2.0

Version 0.2.0 introduces breaking changes to authentication:

What Changed

• Credentials-based authentication (email/password) has been removed
• Service account token authentication is now required
• Token caching logic has been removed (tokens are long-lived)
• The auth module and login endpoint are no longer available

Upgrading

Before (v0.1.x):

client = ConnectClient(
    base_url="https://capi.trintel.co.za",
    credentials={
        "email": "[e-mail]",
        "password": "password"
    },
    cache=cache_instance  # Optional
)

After (v0.2.0):

client = ConnectClient(
    base_url="https://capi.trintel.co.za",
    token="your-service-account-token"
)

How to get a service account token: Contact your Trinity IoT administrator to generate a service account token for your application.

Error Handling

The library raises specific exceptions for different error conditions:

from trinity_connect_client.exceptions import (
    ResourceNotFoundError,
    UnauthorisedError,
    ConnectAPIError
)

try:
    device = client.devices.get(device_id=123)
except ResourceNotFoundError:
    print("Device not found (404)")
except UnauthorisedError:
    print("Authentication failed (401)")
except PermissionError:
    print("Access forbidden (403)")
except ConnectAPIError as e:
    print(f"API error: {e}")
except ValueError as e:
    print(f"Invalid input: {e}")

Development

Setting up Development Environment

# Clone the repository
git clone https://github.com/trinity-telecomms/connect-py-client.git
cd connect-py-client

# Install dependencies with uv
uv sync

# Run tests
uv run pytest

# Run linting
uv run ruff check .

Running Tests

# Run all tests
uv run pytest

# Run with coverage
uv run pytest --cov=connect_client

# Run specific test file
uv run pytest tests/modules/devices/test_devices_api.py

Building the Package

This project uses the uv_build backend for building distributions:

# Build both wheel and source distribution
uv build

# Build only wheel
uv build --wheel

# Build only source distribution
uv build --sdist

# Build to a specific directory
uv build --out-dir dist/

The built distributions will be available in the dist/ directory.
