Azure Telemetry

This block sends telemetry data to Azure IoT Hub. Use it to transmit sensor readings, device status, and application data to the cloud for monitoring and analytics.

Azure Telemetry Block

Overview​

The Azure Telemetry block transmits data from your device to Azure IoT Hub, enabling cloud-based monitoring, analytics, and integration with Azure services.

Configuration​

  • Telemetry ID: The name of the telemetry data to send (e.g. "temperature")
  • Telemetry Value: The value of the telemetry data to send

Telemetry Frequency​

Consider transmission frequency:

  • Real-time for critical data
  • Batched for efficiency
  • Event-driven for state changes
  • Scheduled for regular updates

Data Sources​

Send telemetry from:

  • Variables with sensor readings
  • Calculated values from application logic
  • System status information
  • Aggregated data over time periods

Use Cases​

Common telemetry scenarios:

  • Environmental sensor monitoring
  • Equipment status reporting
  • Alarm and event notification
  • Energy consumption tracking
  • Performance metrics

Integration with Azure​

Telemetry data flows to Azure services:

  • IoT Hub: Initial data ingestion
  • Stream Analytics: Real-time processing
  • Time Series Insights: Time-series analysis
  • Event Grid: Event-driven workflows
  • Storage: Long-term data retention

Error Handling​

Handle transmission failures:

  • Automatic retry on connection errors
  • Queue messages during offline periods
  • Log failed transmissions
  • Alert on persistent failures

Performance​

Optimize telemetry performance:

  • Batch multiple data points
  • Use appropriate transmission frequency
  • Minimize message size
  • Consider network costs
