What type of property in a device twin reflects current values of device settings?

The property that reflects the current values of device settings in a device twin is the reported properties. Device twins are Azure IoT Hub representations of your devices that store various information about them.

Reported properties are used by the device to report its current state or configuration back to the cloud. This means that whenever the device changes its internal state or settings, these values can be updated in the reported properties section of the device twin. This allows the cloud to be aware of the current status of each device, which is critical for monitoring and management.

In contrast, desired properties are used to define the configuration that the cloud wants the device to achieve. Identity properties contain information such as the device ID, and tag properties are used to group devices or categorize them, but they do not reflect the current settings.
