Node-RED enables use cases in the Internet of Things to be implemented using a simple modular principle. Specifically, this means connecting hardware, interfaces, and services via graphical programming in the flow editor. This involves connecting so-called nodes to form a flow, or program sequence. A large selection of predefined building blocks, as well as nodes and flows from other users in the Node-RED library, cover most of the common services and technologies.

Note: After installing Node-RED, you still need to download the latest Offline Bundle via Marketplace > Blocks > NodeRed.
