Eclipse Paho MQTT Python Client

The Eclipse Paho MQTT Python Client library provides classes for applications to connect to an MQTT broker, publish messages, and subscribe to topics to receive messages. It supports MQTT versions 5.0, 3.1.1, and 3.1, and is designed for lightweight publish/subscribe messaging, suitable for IoT and M2M communication where bandwidth or code footprint is a concern. The current stable version is 2.1.0, with regular updates and an active development cadence as part of the Eclipse Foundation projects.
