I'm trying to create new Azure Monitor Alert using PS script. I'm using MS documentation here: https://docs.microsoft.com/en-us/powershell/module/az.monitor/add-azmetricalertrulev2?view=azps-5.9.0

I am trying to enable certs at the IoT Edge device end I am using the demo certs but the iothub module is failing with below error

I get an ERROR: The request did not have a subscription or a valid tenant level resource provider. when trying to create a service principal via the azure cli under the scope of an Azure Iot Hub. I'm using the CLI (bash) but python would be sufficient, too.

As shown at end, i have correct credentials & rights to create sp's in this subscription, and i have owner rights to the iot hub in question.

In case i'm missing a better way to accomplish this, here is the context: We need to authenticate a job that automates the registration of new devices immediately after they are flashed, before they are shipped off to be plugged in. This does many things to customize the flashed filesystem (add unique device hostname & local passwords, for instance); and finally it needs to register the device with IotHub.

I am able to successfully connect with a python example to my created IoT Edge. However, the same configuration does not work for my actual downstream device (ESP8266).

I am using the following example for the ESP8266: https://github.com/Azure/azure-iot-arduino/tree/master/examples/esp8266/iothub_ll_telemetry_sample

Added the certificate and connection string in the code:

I want to regularly update the desired properties for IoT Device. The desired properties that I am sending is as follows:

On the Azure IoT Hub's "IoT devices" page I am getting an error:

Using IOTHub message routing feature, I am able to listen device twin change notifications whenever there is any change in device twin.
No matter whether it is a change in tags or reported properties or desired properties.
What I am looking for is a way to filter out events when reported properties are changed. I don't want (or I would like to ignore) any notification for changes in tags or desired properties.

For now, as of my research it can be only done by maintaining last reported properties version and comparing it with new event reported properties version.

Please enlighten me if any other way is there without having to maintain last version details somewhere.

I am using Python 3.8.2 on Linux and the azure iot python sdk version 2. I have setup device provisioning in the Azure Portal and can successfully provision my device using the following code.

I am looking for an endpoint in Azure IotHub to download the full configuration of an edge device.
