The task that led to this report, T3.2, aimed at integrating the LPC in selected devices in project pilots. The report details how and why particular devices (e.g., large scale grid batteries and electrical heat pumps) were selected to showcase the integration in German, Spanish, and Austrian pilots. This report demonstrates a variety of transformations from/to devices, including Modbus-to-NATS and MQTT-to-NATS conversions, as well as mapping from nonstandard message formats to DERStatus and MirrorMeteringList data models of IEEE 2030.5. Readers are advised to read this report jointly with D3.3 Report on the Software Tool Integration with Selected Platforms, as devices and EMSs constitute the overall nexus for monitoring and control of hybrid energy storage systems and thus, represent the end points of communications enabled by the LPC. While specific applications may require different efforts in integration (e.g., different data models and communication workflows), the combination of these two documents provides comprehensive coverage and valuable insights, derived from project pilot activities, that can guide future implementations.
