  Monitoring Remotely with MQTT

  Content Type
  Exercise

  Duration
  25m

  Level
  Introductory

  Use the interoperability tools built into InterSystems IRIS® for Health to construct a basic user portal that monitors live health readings from a set of remote patients.

  MQTT is one of the most common messaging protocols used in the IoT world. Its lightweight structure and topic-based architecture enable fast and efficient message transmission, even over very low bandwidth. In this exercise, you will use a minimal amount of code to quickly take real-time data coming from an MQTT broker, then save and display it on a dashboard.

  Learning Objectives

  • Create a production that subscribes to an MQTT topic and passes messages into the interface.
  • Create a dashboard to view live patient data.

  What's Next?

  You have now successfully built a dashboard that monitors remote patient heart rates. In doing so, you have seen how you can use MQTT to share data between devices and applications with limited bandwidth, and limited implementation effort from developers.

  • Read more about using MQTT adapters in productions (documentation, 5m).
  • Use device data to track patient care with FHIR (exercise, 40m).
  • Learn about the built-in MQTT passthrough business service and business operation (documentation, 15m).
