NMEA data into Victron Venus using Node Red

First project with Node Red and learning, albeit slowly!

I have a Victron Cerbo connected to an NMEA network. The NMEA network has all battery data on it, and I would like to take this information and pass it into the Victron Cerbo, as a battery meter, using Node Red.

Any tips on how to go about this woudl be greatly appreciated.
