The Controller

Up to this point, we have mostly focused on creating things, either sensors or actuators that publish data in one form or another and allow other actors to perform control operations on them. In this chapter, we will focus on how to find such devices, consume their data, and how to issue control operations on them. The chapter covers:

  • Discovery of devices on the Internet of Things
  • An introduction to Thing Registry
  • How to register a device in a registry
  • How to discover devices in a registry
  • How to subscribe to sensor data events
  • How to issue control operations
