This OptoTutorial shows how to:

  • Use Node-RED to subscribe and publish to an MQTT message stream
  • Parse message strings
  • Display data from a message in groov View
  • Push data from groov View and from a SNAP PAC controller to a message stream
Note: The tutorial uses a groov Box (part number GROOV-AR1-BASE) as an example. The groov Box is a legacy product not recommended for new applications, but it is still available and supported.
