Watch recorded conference sessions for FREE and learn how to connect your systems with Node-RED.

Included in groov EPIC and groov RIO is Node-RED, an open-source software program that allows you to wire together devices, databases, cloud applications, and APIs (application programming interfaces) using simple logic flows.

Node-RED is being used in a wide range of mission-critical applications, from city utilities and semiconductor fabs to manufacturing lines and smart buildings.

Anywhere an engineer needs two systems to talk, Node-RED often shows up. It’s a visual way to move data, trigger actions, and link systems. Due to Node-RED's growing popularity, it's no surprise that last week's Node-RED conference provided some excellent resources and idea exchanges.

Discover the key takeaways from the conference and gain access to the session recordings.
