Curious to know how to access your industrial data over MQTT?

If so, check out Subscribe and Publish with MQTT Nodes, groov & SNAP PAC, our newest step-by-step OptoTutorial.

In it, you’ll learn how to:

  • Use Node-RED to subscribe and publish to an MQTT message stream
  • Parse message strings
  • Use groov to display data from a message
  • Push data from groov and from a SNAP PAC controller to a message stream

For most of the activities, all you need are a groov Box running groov R3.3 or higher, and a few minutes to work through the examples.
