mqttools 0.4.0

MQTT tools.

MQTT Tools

Requires Python 3.7 or later!

NOTE: This project is far from complete. Lots of MQTT features are not implemented yet, and those implemented are probably buggy.

Features:

• asyncio MQTT 5.0 client (under development).

MQTT 5.0 specification: https://docs.oasis-open.org/mqtt/mqtt/v5.0/os/mqtt-v5.0-os.html

Examples

Command line

Subscribe

An example connecting to an MQTT broker, subscribing to the topic /test/#, and printing all published messaged.

$ mqttools subscribe /test/#
Topic:   b'/test'
Message: b'11'

Topic:   b'/test/mqttools/foo'
Message: b'bar'

Publish

An example connecting to an MQTT broker and publishing the message bar to the topic /test/mqttools/foo.

$ mqttools publish /test/mqttools/foo bar
Topic:   b'/test/mqttools/foo'
Message: b'bar'
QoS:     0

Scripting

Subscribe

An example connecting to an MQTT broker, subscribing to the topic /test/#, and printing all published messaged.

import asyncio
import mqttools

async def subscriber():
    client = mqttools.Client('test.mosquitto.org', 1883, b'mqttools-subscribe')

    await client.start()
    await client.subscribe(b'/test/#', 0)

    while True:
        topic, message = await client.messages.get()

        print(f'Topic:   {topic}')
        print(f'Message: {message}')
        print()

asyncio.run(subscriber())

Publish

An example connecting to an MQTT broker and publishing the message bar to the topic /test/mqttools/foo.

import asyncio
import mqttools

async def publisher():
    client = mqttools.Client('test.mosquitto.org', 1883, b'mqttools-publish')

    await client.start()
    await client.publish(b'/test/mqttools/foo', b'bar', 0)
    await client.stop()

asyncio.run(publisher())
