101 Mini-Lessons

This category usually has mini lessons written by the guys and gals at Opto, but if you feel so inclined to put together a mini how-to or lesson on anything Opto 22 related, we would love to host/post it here.


Node-RED is an open-source software development environment that lets you wire together devices, databases, cloud applications, and APIs (application program interfaces) with simple logic flows. It’s a visual tool often used for Internet of Things (IoT) and Industrial Internet of Things (IIoT) applications. Node-RED software and the two SNAP PAC controller Node-RED nodes are built into the GROOV-AR1 groov Box, making it easier to build mobile operator interfaces for monitoring and controlling IoT and IIoT data.


Here is the place to post your questions about using Inductive Automation's Ignition Edge running on the groov Box.
