IoT Plug and Play, modeling IoT Central devices

If you have built an IoT Device yourself and are finally able to send telemetry to the cloud, you should be familiar with the scenario where you have to repeat the hard work of describing the messages all again on ingestion.

IoT Devices expose D2C telemetry and it can also support C2D communication. This interface is most of the time unique for that device. To be able to get insights from a device you have to be able to react to its interface.

Wouldn’t it be nice if a device was able to provide metadata about its interface once it connects to the cloud? This way, the incoming D2C telemetry could automatically result in e.g. a full user interface. And all C2D output could be represented by pre-configured input controls.

With IoT Plug and Play this is all possible:

IoT Plug and Play enables solution builders to integrate smart devices with their solutions without any manual configuration. At the core of IoT Plug and Play, is a device model that a device uses to advertise its capabilities to an IoT Plug and Play-enabled application

Microsoft provides a way to describe the interface of a device and annotate every feature.

To experience how this works, we will look at the best example: Azure IoT Central.

This SaaS IoT Dashboard makes perfect use of the ability how devices can expose their meta-model.

Let’s see how.
