Introduction to queries

Dive into the versatility of our API with an array of queries, mutations, and subscriptions designed to empower your applications. Here's a glimpse into the possibilities:

• Live Data Access: Stream real-time HAN-reader data directly to your application or API:

  subscription { realTimeMeasurement (...)}

• Historical Data Retrieval: Dive deep into historical measurements with granular detail, down to two-second intervals:

  query { measurements(...)}

• Aggregated Reports: Generate detailed reports, aggregating data for insightful analysis:

  query { reports(...)}

• Consumption Alerts: Set up customized alerts for HAN-readers to keep track of energy consumption:

  mutation { addEstimatedHourlyActiveEnergyLimitWarningAlertSetting(...)}

Enhance your application with:

• Detailed permission and access management for HAN-readers.
• Simple updates and deletion of existing alerts.
