#Huddle Rooms

##Huddle Room state detection in real-time, Powered by MQTT, Node, & Socket.io

###Broker Setup Install Mosca Mcollina/mosca (a Node.js MQTT Broker): npm install mosca

and get it up and running with: mosca -v | bunyan

Now you have a MQTT Broker running that you can publish or subscribe to various topics by using simple url style endpoints i.e. publish to the topic teamone/huddlerooms/huddle1/moving/ with the message via a MQTT Client. or a web browser can subscribe to a topic using websocket to communicate.

In our setup we'll be using Socket.io to make this easier. Our node.js server is running localhost socket for web clients to connect to. In our /panel/index.html we connect to our socket.io connection here: var socket = io.connect('http://localhost:3000'); socket.on('connect', function () {};

and here's our MQTT topic subscription: socket.emit('subscribe', {topic : 'home/#'});

###Front End web app Next we'll install the Node.js based web browser client to subscribe and display the state of the Huddlerooms. https://github.com/fabaff/mqtt-panel
