Linking third party IoT Hub

Question

I've been running a DPS service with connected IoT hubs in my account.

How would I link a 3rd party IoT Hub to one of my enrollments so I can register to them?

I tried having the third add me to their IoT Hub resource, but it seems like I wind up having a separate directory that I can't access between them.

Is there a good way to give access to our DPS from their IoT Hub so that we can link to it? And what permissions would that need?

Hello @Jerry , Thanks for reaching out to us!.

Using the Azure portal:

Link the IoT hub and your Device Provisioning Service

Using Azure CLI : az iot dps linked-hub create

Choosing different subscriptions during linking the IoTHub to DPS.

When creating the Azure IoT Hub DPS resource, you can pass the list of IoT Hubs to link to as part of the properties.

Example:

{  
  "location": "East US",   
  "type": "Microsoft.Devices/ProvisioningServices",  
  "properties": {  
     "iotHubs": [  
        {  
          "applyAllocationPolicy": true,  
          "allocationWeight": "1",  
          "connectionString": "HostName=iothub-001.azure-devices.net;SharedAccessKeyName=iothubowner;SharedAccessKey=xxxxxxxx",  
          "location": "East US"  
        },  
        {  
          "applyAllocationPolicy": true,  
          "allocationWeight": "1",  
          "connectionString": "HostName=iothub-002.azure-devices.net;SharedAccessKeyName=iothubowner;SharedAccessKey=xxxxxxxx",  
          "location": "East US"  
        }  
      ]  
  }  
}
