You export the flow as normal and then copy it into a Node.js folder that is downloaded to the ESP
This is the extract from the instructions which suggests that the debug can be used and the results display in the ESP debugger, but I don't understand this and have not tried it yet 
Debug
- Console output is displayed in the xsbug log pane
- Sidebar output is displayed in the xsbug message pane
- Display of selected property or complete message
- Output to node status (maybe meaningless on device)
From what I understand this was not a particular presentation, Peter and Nick met up for a chat and this was the great result
