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.
