How do I receive messages from Iothub?
To monitor the messages that are sent from your device to your IoT hub, follow these steps:
- Right-click your device and select Start Monitoring Integrated Event Endpoint.
- Monitored messages will be displayed in the OUTPUT > Azure IoT Hub view.

Which of the following is the default endpoint for sending device-to-cloud messages to the IoT hub from a device?
An IoT hub has a default built-in endpoint (messages/events) that is supported by Event Hubs. You can create custom endpoints to route messages by linking other services in your IoT Hub subscription.
Routing also provides a query capability to filter data before it is routed to endpoints. In addition to device telemetry, you can also send non-telemetry events that can be used to trigger actions.
How do I use Device Explorer twin?
You can access device twin information on the Device Twin tab. If a device is connected and actively sending data, you can view telemetry on the Telemetry tab. You can call a direct method on the device in the Direct Method tab. You can send a message from the cloud to the device in the Cloud messages to device tab.
How do I use Device Explorer?
To work with the file system of a device, proceed as follows:
- Click View > Tool Windows > Device File Browser or click the Device File Browser button on the tool window bar to open Device File Browser.
- Select a device from the dropdown list.
- Interact with the content of the device in the file browser window.
How does Event Grid work with IoT Hub?
When you subscribe to telemetry events through Event Grid, IoT Hub creates a default message route to send device messages of type data source to Event Grid. For more information about message routing, see IoT Hub message routing. This route will be visible in the portal under IoT Hub > Message routing.
How to subscribe to eventgrid as event source?
To continue with Event Grid events, go back to the Event tab in your IoT Hub. Add an event subscription and name it “DeviceRelated”. The default selected event types to send are device creation, device removal, device connected, device disconnected. And we see the event schemas:
How can eventgrid manage telemetry payloads?
EventGrid can handle bulk telemetry uploads. Event Grid has guaranteed delivery, it tries to deliver messages for 24 hours. IoT Hub tries to send its events for one hour to the EventGrid. You can control how messages are sent and received. Let’s start consuming events coming from the IoT Hub.
When does a device register with an IoT Hub?
The DeviceTelemetry event is raised when a telemetry event is sent to an IoT Hub. Below is a sample schema for this event. The schema for the DeviceCreated and DeviceDeleted events have the same structure. This sample event shows the schema of an event generated when a device checks in to an IoT hub: Unique identifier for the event.
