I re-added a "meteobridge" device and have both of them working now. There is no distinction available (or needed) for the PRO. My main problem was that I did not save the ID/Key combination for the "MB PRO". When I re-registered, the device number ID and Key appeared in a pop-up window. This time I saved them to a text file before I put them into the "weather networks" tab for meteobridge.
