IoT gateways with Node-RED
There are various ways to implement an IoT gateway. The innovative low-code platform Node-RED was designed to realize IoT applications, data acquisition, local processing, and cloud integration without programming knowledge. With Node-RED, it is easy to create a connection between old and new industrial technologies in terms of IoT (Internet of Things). It provides a browser-based flow editor that easily connects flows using a variety of network nodes available in the palette. A node always has at least one input or output. Messages are then sent between the nodes, which can be processed or manipulated in a variety of ways.
