This is the MQTT.org Wiki

It might be a bit rough around the edges still, but we're working on it.

• Basic Concepts
• Example Uses

• Really Small Message Broker
• Mosquitto Message Broker

• WMQTT IA92 Java utility

Documentation of the available APIs for building MQTT clients, examples of using these APIs can be found in Scripting Strategies and API Usage Examples:

• PHP
• Perl WebSphere::MQTT::Client
• IBM IA93 MQTT C Client
• Arduino Pub/Sub Client
• Delphi
• .net
• Java
• libmosquitto (C client library)
• libmosquittopp (C++ client library)
• libmosquitto-python (Python client module)
• Ruby

One particular area of mqtt that can be hard to understand is the strategies required to process data to achieve the desired output. Below are common approaches to common tasks and examples using the APIs above:

• Integrating Current Cost Meters
• Using Pachube with MQTT
• Using MQTT with Twitter and Identi.ca
• Logging MQTT Messages in Databases
