HBMQTT
======

``HBMQTT`` is an open source `MQTT`_ client and broker implementation.

Built on top of :mod:`asyncio`, Python's standard asynchronous I/O framework, HBMQTT provides a straightforward API
based on coroutines, making it easy to write highly concurrent applications.

Features
--------

HBMQTT implements the full set of `MQTT 3.1.1`_ protocol specifications and provides the following features:

- Support QoS 0, QoS 1 and QoS 2 messages flow
- Client auto-reconnection on network lost
- Authentication through password file (more methods can be added through a plugin system)
- Basic ``$SYS`` topics
- TCP and websocket support
- SSL support over TCP and websocket
- Plugin system


Requirements
------------

HBMQTT is built on Python :mod:`asyncio` library which was introduced in Python 3.4. Tests have shown that HBMQTT run
best with Python 3.4.3. Python 3.5.0 is also fully supported and recommended. Make use you use one of these version
before installing HBMQTT.

Installation
------------

It is not recommended to install third-party library in Python system packages directory. The preferred way for
installing HBMQTT is to create a virtual environment and then install all the dependencies you need. Refer to
`PEP 405`_ to learn more.

Once you have a environment setup and ready, HBMQTT can be installed with the following command ::

  (venv) $ pip install hbmqtt

``pip`` will download and install HBMQTT and all its dependencies.


User guide
----------

If you need HBMQTT for running a MQTT client or deploying a MQTT broker, the :doc:`quickstart` describes how to use
console scripts provided by HBMQTT.

If you want to develop an application which needs to connect to a MQTT broker, the :doc:`client` reference documentation
 explains how to use HBMQTT API for connecting, publishing and subscribing with a MQTT broker.

If you want to run you own MQTT broker, th :doc:`broker` reference documentation explains how to embed a MQTT broker
