Hi @edoardoo I actually stumbled on your post a couple of weeks ago! Great writeup! We certainly need contributors. We need help with everything from the visualisation of sensordata in the frontend (considering using d3.js) to mqtt/node.js backend for receiving and processing sensor data. Please contact me or Johan for further discussions.
