I'm trying to integrate a particle development board but i'm having issues with IoT Hub.
I am having trouble seeing my IoT Hub from the azure CLI.
When i run
az iot hub monitor-events -n Gateway-Electronic-Components
it returns
Unable to find IoT Hub: Gateway-Electronic-Components in current subscription "blah blah".
I have verified the hub is created in the dashboard and the name is correct
Also
When i run the below it returns an empty table.
az iot hub list -o table

Hello @Joshua Bailey , Thanks for reaching out to us!.
I just verified my IoTHub events from Azure CLI, it is showing events sent by my device.
Did you verify the name of the IoT hub matching exactly?
Please let us know if you need further help ...
If your IoThub provision is a success then it must show up in the below command.
az iot hub monitor-events -n sabodiothub
Hello @Joshua Bailey , Thanks for reaching out to us!
I have created a new IoTHub with a similar name 'Gateway-Electronic-Components' and was able to monitor telemetry events.
I was also able to run the below command,
az iot hub list -o table
Please let us know if you need further help in this matter.

I am having the same problem but with the cloud shell.
Sometimes the IoT Hub cannot be found and I can't monitor the data sent by my IoT device. I don't know the reason. How should I debug it and fix the problem? I did some investigation with what is suggested here. But, I am still stuck.
Case A: When it is working, I get the data.
$ az iot hub monitor-events --hub-name MikeProjectHub --device-id MyIoTDevice
Starting event monitor, filtering on device: MyIoTDevice, use ctrl-c to stop...
{
"event": {
"origin": "MyIoTDevice",
"payload": "{"deviceId":"ESP32Device", "messageId":1, "Temperature":26.400000, "Humidity":65.000000}"
}
}
Case B: When it is not working, I get the error message saying that the hub is not found.
michael [ ~ ]$ az iot hub monitor-events --hub-name MikeProjectHub --device-id MyIoTDevice
Unable to find IoT Hub: MikeProjectHub in current subscription b35ecede...
Testing shows me that I must keep trying until the hub is available. So, the hub is not always available for me to monitor for data. Is this same problem for all other users? Is there a better way to monitor for data?

I never actually got the bottom of why the hub i created through the dashboard didn't show in the CLI. I ended up creating a hub using the CLI command and it worked first time.
Glad to see that you have resolved your issue.

I have having same issues. Some weeks ago, i was able to see IOT Hub , but now unable to see it in my subscription when i use CLI command.
However when i go through the Azure web interface, i am able to see that the IOThub is attached to the subscription and resource group

I have the same issue now. I can see the IoTHub in Azure portal but cannot find it by CLI.
This has happened last few days and I couldn't test my incoming messages ( may have to try something alternate - Azure IOT Explorer on Mac doesn't work |!! - On github mac says not supported) .
Anyways went ahead and deleted the hub and created a new one ( that hub was an old one without dependencies) . Still same issue. In CLI it isn't able to detect the hub at all (az iot hub throws nothing - yea i checked its the same subscription)
(However, az resource list - shows the iot hub names - weird !)
Seen some other people in other forums also reporting this.
I deleted the hub and created new one. still same issue
(az iot hub list - doesn't show anything)
(az resource list - shows the iot hub name !!! - weird)
@Cykus Systems
I have tried the "az iot hub list -o table" command today. It's fine now. I think maybe they fix the issue.
