PyMosquitto

A lightweight Python MQTT client implemented as a thin wrapper around libmosquitto.

Dependencies

• python3.8+
• libmosquitto1

Installation

• pip install pymosquitto

TODO

• implement the remaining bindings

Usage

from pymosquitto.client import MQTTClient


def on_message(client, userdata, msg):
    print(msg)


client = MQTTClient()
client.on_connect = lambda *_: client.subscribe("#", 1)
client.on_message = on_message
client.connect_async("localhost", 1883)
client.loop_forever()

Async client example:

import asyncio

from pymosquitto.aio import AsyncMQTTClient


async def main():
    async with AsyncMQTTClient() as client:
        await client.connect("localhost", 1883)
        await client.subscribe("#", 1)
        async for msg in client.recv_messages():
            print(msg)


asyncio.run(main())
