Paho provides client implementations of the MQTT protocol.
Mihini is an embedded Lua runtime providing HW abstraction and other services.
Koneki provides tools for embedded Lua developers.
Eclipse SCADA is a complete Java/OSGi-based SCADA system (communication, monitoring, GUI, …)

Is the MQTT API that simple?
Is the MQTT API that simple? MqttClient mqttClient = new MqttClient ( "tcp://iot.eclipse.org:1883", MqttClient.generateClientId() );
mqttClient.setCallback(…);mqttClient.connect();mqttClient.subscribe("myGreenhouse/#");// the rest of your app
Is the MQTT API that simple?
mqttClient.setCallback(new MqttCallback() {@Overridepublic void messageArrived(String topic, MqttMessage message) throws Exception { // process received message // e.g. display temperature value}// ...
});
Callback code:
Data viz. w/ MQTT over Websockets
• Rickshaw is a JavaScript toolkit for creating interactive time series graphs
• It’s built on top of d3.js
• MQTT over Websockets makes it very easy to feed data into Rickshaw datasets
– More at http://code.shutterstock.com/rickshaw – lots of examples to get started
In a nutshell
• MQTT is a very versatile protocol for building your IoT solution from the ground up. You should try it!
• Eclipse IoT has lots of projects, from basic building blocks to more complete solutions
• We have Java, and more! J
