Overview

The AIIDA system primarily runs on an in-house device (e.g., a Raspberry Pi) and the eligible party's infrastructure. To access near real-time data, it relies on a Data Source, which sends energy-related data to the AIIDA application. The Data Source can be either an adapter to a metering device (such as a smart meter) or an IoT device that measures energy data itself. Depending on the Data Source type and model, it may use different communication protocols both for connecting to the AIIDA application (e.g., MQTT over Wi-Fi), and for connecting to the metering device (e.g., DSMR over RJ12). The AIIDA application stores near real-time data in the Timescale DB and also sends this data to the AIIDA Region Connector via MQTT, which then makes the data available to the EDDIE Framework.

Node	Description
In-house Device	The in-house device is a Raspberry Pi computer, which is operated by the customer. It is connected to the customer's local area network.
Measuring Device	The measuring device, e.g., the smart meter of the customer, collects energy data at the customer's site.
Data Source	The Data Source is a device that sends energy-related data to the AIIDA application. Multiple Data Sources are supported, each one providing different connectivity options. The supported Data Sources and their connectivity are mentioned in the Data Source section.
Eligible Party Infrastructure	This is the computing infrastructure that hosts the EDDIE Framework. The AIIDA Region Connector is a plugin of the EDDIE Framework and communicates with the EDDIE Core.
