mqtty

mqtty is a flexible Python package that bridges MQTT communication with serial devices. It provides an agnostic approach to MQTT client libraries, supporting both paho-mqtt and aiomqtt through helper functions, while allowing developers to manage multiple serial devices seamlessly.

Key Features

• Serial Device Integration: Easily connect serial devices using serial_device_factory and register them under unique MQTT topics.
• Execution Mode Flexibility: Choose between synchronous (threaded) or asynchronous modes to suit your application's requirements.
• MQTT Client Agnostic: Use your preferred MQTT library, with helper functions like connect_paho_mqtt and connect_aio_mqtt.
• Multi-Device Management: Use the manager to register and manage multiple serial devices, routing messages between MQTT topics and serial ports effortlessly.

Installation

Install mqtty via pip:

pip install ki2-mqtty

Quick Start

Here are examples of how to use mqtty in synchronous and asynchronous modes.

Synchronous Example

import paho.mqtt.client as mqtt
from paho.mqtt.enums import CallbackAPIVersion

from mqtty import serial_device_factory, manager_setup, connect_paho_mqtt

def main():
    mqttclient = mqtt.Client(CallbackAPIVersion.VERSION2)

    device = serial_device_factory("/dev/ttyACM0")
    manager = manager_setup("threaded").register("device-topic", device)

    connect_paho_mqtt(mqttclient, manager=manager)

    manager.start()
    mqttclient.connect("localhost", 1883, 60)
    mqttclient.loop_forever()

if __name__ == "__main__":
    main()

Asynchronous Example

from datetime import datetime
import asyncio

from aiomqtt import Client as AioMqttClient

from ki2_python_utils import run_parallel
from mqtty import serial_device_factory, manager_setup, connect_aio_mqtt

async def main():
    mqttclient = AioMqttClient("localhost", 1883)

    device = serial_device_factory("/dev/ttyACM0")
    manager = manager_setup("async").register("device-topic", device)

    mqtt_loop = connect_aio_mqtt(mqttclient, manager=manager)

    await run_parallel(
        manager.loop,
        mqtt_loop,
    )

if __name__ == "__main__":
    asyncio.run(main())

How It Works

1. Device Registration: Use serial_device_factory to create a serial device and register it with the manager. Each device is associated with an MQTT topic for message routing.
2. Manager Setup: Initialize the manager in either "threaded" or "async" mode, depending on your application's requirements.
3. MQTT Integration: Use the provided helper functions to connect the manager to your MQTT client (paho-mqtt or aiomqtt).
4. Run Your Application: Start the manager and MQTT client loop to enable communication.
