Node-RED has an ample library with already predefined nodes which are
ready for immediate use.

Node-RED categorizes nodes. The following categories of nodes exist,
e.g.:

input

output

function

social

storage

analysis

advanced

cloud

modbus

dashboard

Nodes offer functions, e.g.:

Web-based communication

TCP/UDP send/receive

MQTT publish/subscribe

Serial send/receive

Time emitter
