(formerly known as asyncio-mqtt)
Write code like this:
Publish
async with Client("test.mosquitto.org") as client:
await client.publish("humidity/outside", payload=0.38)Subscribe
async with Client("test.mosquitto.org") as client:
await client.subscribe("humidity/#")
async for message in client.messages:
print(message.payload)aiomqtt combines the stability of the time-proven paho-mqtt library with an idiomatic async interface:
- No more callbacks! 👍
- No more return codes (welcome to the
MqttError) - Graceful disconnection (forget about
on_unsubscribe,on_disconnect, etc.) - Supports MQTT versions 5.0, 3.1.1 and 3.1
- Optionally: separate queues per subscription. No more overhead for dispatching.
- Fully type-hinted
- Did we mention no more callbacks?
- Works with asyncio and trio! No workarounds required!

Is aiomqtt not what you're looking for? There are a few other clients you can try:
- paho-mqtt: Synchronous client
- micropython-mqtt: Asynchronous client for microcontrollers in MicroPython
- gmqtt: Asynchronous client
- fastapi-mqtt: Asynchronous wrapper around gmqtt; Simplifies integration with FastAPI
- amqtt: Asynchronous client; Includes a broker
- trio-paho-mqtt: Asynchronous wrapper around paho-mqtt; Based on trio instead of asyncio
