How to check the firmware version of an IoT device.

Question

Hello.

I want to use Azure to manage the firmware version of my IoT device.

I have confirmed that Device Update for IoT can be used to update the firmware of IoT devices.
I have also confirmed that I can see the deployment history of the firmware to the IoT devices.

Is there a screen that displays a list of devices and shows the firmware version of each device?
Do I need to create my own screen that extracts and displays the firmware information from Device Twin?

Thanks in advance.

Hello @HinataGrape-6694 ,
You can use Azure IoT explorer (see how to Install and use Azure IoT explorer).

The Azure IoT explorer is a graphical tool for interacting with devices connected to your IoT hub. You can use the tool to view the telemetry the devices are sending, work with device properties, and invoke commands. You can access the device twin information on the Device Twin tab.

You can also considering using IoT Hub query language to retrieve information regarding device twins. See IoT Hub query language for device and module twins, jobs, and message routing .

For example:

SELECT * FROM devices  
  WHERE properties.reported.firmwareVersion = 2.0
