Azure IoT Shadow and topics¶
In Azure, the IoT Hub Device Twins are used to send device data and configuration through the JSON shadow documents. A shadow document describes the different states of the device through a state property. Examples of device states are:
- Reported state
- Desired state
Reported state¶
The document is described in the JSON schema file for the reported state.
See JSON document containing a reported state for a sample device state.
Desired state¶
The document is described in the JSON schema file for the desired state.
See the JSON document containing a desired state for a sample device state.
