Vaadin MQTT Dashboard sample for Bluemix

There are several displays for MQTT based Bluemix IoT dashboards:

round gauge with text value
vertical bar display
sparkline for history data
polar display for directional data
list display for text messages

By default the application shows drone altitude, message log and slider to set the drone altitude.

Get the source and compile

To compile the the application locally, use:

 git clone https://github.com/samie/bluemix-mqtt-dashboard.git
 cd bluemix-mqtt-dashboard
 mvn install

NOTE: the application does not work out-of-the-box and you need to configure the IoT foundation first.

Setting up IoT foundation for messaging

First you need to setup the The IBM Internet of Things service in your Bluemix dashboard and configure the application.

You can find the application configuration in the iot-foundation.properties. Copy the required configuration data from the dashboard "Devices" and "API keys" tabs.

Note that, if you add more displays in your code, a different client id is needed for every connecting client.

 mvn jetty:run
 open http://localhost:8080/drone

 cf push <your-app-name> -p target/bluemix-mqtt-dashboard-1.0-SNAPSHOT.war
