The Eclipse Paho MQTT Python client library implementing MQTT protocol versions 5.0, 3.1.1, and 3.1. It enables Python applications to connect to MQTT brokers to publish messages and subscribe to topics.

Use cases

• connect python app to mqtt broker
• publish messages to mqtt topics
• subscribe to mqtt topics with callbacks
• build iot device communication in python
• lightweight pub/sub messaging for embedded sensors
• one-off publish to mqtt server

When to choose

• you need MQTT v5, 3.1.1, or 3.1 support in Python
• you want a mature, Eclipse Foundation-backed MQTT client
• you need publish/subscribe messaging with low bandwidth overhead
• you want helper functions for simple one-off publishing

When to avoid

• you need persistent client sessions across program restarts (sessions are memory-only)
• you need a full message broker rather than a client
• you're on Python older than 3.9
• you need Kafka-style or AMQP messaging instead of MQTT
