Visual Integration Tools

On my IoT Gateway two components have a great importance:

• NodeJS
• Node-Red

Normally, an IoT Gateway has several task to do. Amongst the others:

• Register locally values received from Sensor Nodes;
• Transform message format

Node-Red is a great integration tool, based on NodeJS, but with a Visual Designer.

For example, with this simple flow, I take a msg from a MQTT Topic, I do some simple transformations and then I store the readings from sensors in a MySQL table.
