Is there any azure iot telemetry device to cloud reader we can use? Azure IoT Explorer is not working.

Question

Azure IoT Explorer is no longer working as expected. Is there any other Azure IoT telemetry device to cloud reader we can use?

Hi Rikard Tidala

It seems you are facing issues on using Azure IOT explorer. I guess you might need to check whether the devices are connected state or not. You might need to disconnect and reconnect or change Connection strings /authentication.

Please make sure you have registered the needed RP (Azure from Subscriptoin.

Here are alternative options

Azure Data Explorer (ADX)

Azure Data Explorer is widely adopted across Microsoft for telemetry ingestion and analytics. It supports:

• Real-time telemetry analysis
• Time series, anomaly detection, and forecasting
• Integration with Azure Logic Apps for alerting
• Visualization via Web UI, Kusto.Explorer, or Jupyter notebooks

Azure IoT Hub SDKs

The SDKs allow secure device connectivity and telemetry ingestion. You can:

• Send telemetry using MQTT, AMQP, or HTTPS
• Use device twins for state reporting
• Upload large telemetry batches via Azure Blob Storage.

Log analytics workspace

You can enable diagnostic setting from IOT hub /monitor tab and route the telemetry data to log analytics or storage.

and create custom dashboard to monitor any desired metrics on specific devices.

Azure Stream Analytics

Ideal for complex rule processing at scale. It can process telemetry streams and trigger actions or alerts based on defined conditions

Azure IoT Central

Provides a dashboard-driven experience for managing devices and viewing telemetry. It supports:

• Edge device provisioning
• Visualization of telemetry via charts and KPIs
• Rule-based actions and extensibility via APIs

https://learn.microsoft.com/en-us/azure/iot-edge/how-to-collect-and-transport-metrics?tabs=iothub

Azure CLI and REST APIs

While there’s no direct REST API to consume device-to-cloud messages, you can use:

• Azure CLI for telemetry simulation and monitoring as mentioned above from Dominic.
• Event Grid integration for event-driven telemetry handling

Hope it helps.

Thank you

Hello @Rikard Tidala ,

welcome to this moderated Azure community forum.

The Azure IoT Explorer seems a bit sensitive.

An other alternative next to those mentioned here is making use of the VS Code IoT Hub extension.

Just connect to an IoT Hub via the connection string or via the wizard and you are good to go. Just follow along with the dialogs.

As an alternative, you could also forward messages to an Azure EventHub and use the new 'Data explorer' dialog to read the latest incoming messages:

This should help you testing for incoming messages.
