Telemetry

Telemetry is a special type of property. It doesn't store any data and acts like a C# event. More information can be found in Chapter 3, Digital Twin Definition Model.

It is not possible to update the telemetry field of a Digital Twin. It is part of the schema and matches the actual IoT sensor. An additional property is used to store the value in the Digital Twin. This field is normally updated with the latest measured value and is part of the ingress process. Ingress is a way of binding the output of a sensor to the Azure Digital Twin. This process will be explained more thoroughly later in this book.

Since we aren't focusing on the ingress process just yet, we will be using a method that generates temperature data and pushes it to the Digital Twin:
