That shouldn’t be a problem. You would need:
1 – Node-Red to grab the data from the API of the local uRadmonitor (OR from the API of Radu himself)
2 – MQTT broker
Both components can be install (together with Domoticz) on a RasberryPi

And then:
– Add the MQTT Client Gateway with LAN interface in Domoticz (= virtual hardware)
– Add a few dummy devices in Domoticz
– Push the data grabbed wit (1) to the MQTT message broker

For more details and how-to’s go to the Domoticz and Node_red sites.

Good luck!!
