Overview of the APIs of the cloud platform.


At aedifion, we firmly believe that any successful future building monitoring, analysis and control systems must be open. Such an open solution allows freely integrating, e.g., third party data sources, services, platforms, databases, output channels, and so forth. And, vice versa, it can also be integrated into third party services, platforms, databases, output channels and so forth.

The single most important feature of an open platform is a comprehensive, well-documented, free and open application programming interfaces (APIs). The platform provides such APIs to any customer.

This article provides a short overview of the APIs of the platform, their features and primary use cases.


All data and functionality offered by the platform can be accessed and manipulated through a RESTful HTTP API. This includes, e.g.,

  • importing, querying, and exporting time series data
  • creating and managing alerts on data and meta data
  • management of users, projects, datapoints, and access permissions
  • creating and managing of virtual datapoints
  • creating and managing all kinds of meta data such as tags, renamings, favorites, etc.
  • setpoint and schedule writing for active building control
  • ...

The HTTP API is actively used in different places, e.g.,

  • the frontend ( interacts with the backend through the HTTP APIs
  • the Excel plugin pulls data from the HTTP API into Excel worksheets
  • the interactive 3D visualization uses the HTTP API to write setpoints
  • voice commands to Alexa trigger calls to the HTTP API to retrieve thermal comfort and to write setpoints
  • ...

Most use cases of the platform center around collecting and acting upon time series data collected in buildings, plants, or whole districts. When such data should be streamed (in real time) in or out of the platform, the strict request/response pattern of HTTP APIs is often not the right choice. Thus, we complement the HTTP API by an MQTT API. MQTT follows a publish-subscribe model that provides convenient and efficient streaming access to live data. The features of the MQTT API include, e.g.,

  • subscribing to all measurement data collected from your buildings, plants, and districts at the level of whole projects or down to single datapoints
  • publishing data into the platform via MQTT
  • receiving notifications and alarms via MQTT
  • websockets support
  • ...

The MQTT API is actively used in different places, e.g.,

  • by aedifion's Edge Devices to send collected data and meta data to the platform
  • the interactive 3D visualization subscribes to live data via MQTT directly from within your browser using websockets
  • the platform publishes alarms created by the user on datapoints via MQTT
