Figure 1: Ultimate-iot-hub
Mike Karliner has used the inexpensive Raspberry Pi to make a really great central hub for small IoT networks as it comes in cheap price and consumes very little power as well as it has no fans or other mechanical parts that might cause failure. This project deals in how to get up and run with an MQTT broker, and node-red, a great visual programming tool, which works great with ThingStudio.
Mosquitto is a popular MQTT broker and it works well on small footprint devices. But, the current version that comes with Raspbian is out of date and therefore, at least 1.4 version is needed here and has to be installed from the source distribution. To deal with this project, one must be well versed with the bash command line and have basic skills in editing of text files with vi or nano.
In part 1 of this project, Mosquitto is built and installed. The step by step procedure is provided on the website of Mike Karliner. You can visit his site for codes and installation.
The part 2 for Node-red is really easy, just go to nodered.org and follow the instructions. And this is done and ready to create some great solutions with your Raspberry Pi and ThingStudio.
