The CIM Data Source allows connecting to any device which supports communication over MQTT. The CIM Data Source Adapter is a general purpose adapter that can be used if no specific adapter is available for a device. It uses the TimeSeries object of the Real Time Data Market Document to parse incoming data.

Connection to AIIDA

Devices can send data to the MQTT broker of the EDDIE instance on the dedicated topic for the CIM Data Source.
