The change node will help you to delete certain parts of a payload, move data from one subsection of the object to another or change parts of the payload to a new value. Use-cases like chatbots or sorting readings of combined sensors are discussed briefly. Node-RED is a graphic interface based software you can run on your computer, server or Raspberry Pi. Beside directing and processing data streams, you can use it to build simple chat bots, collect sensor date unsigned a Raspberry Pi, build logic arrays, smart home applications, feeding data in a (SQL) database, possibilities are endless!
