OpenPlotter data to Python

Thanks for that link.  While it mainly refers to serial communications I notice that TCP can also be bi-directional. I'll keep experimenting.

Yes didn't notice that it only referred to serial. 
Why not use the default tcp connection? Connect to port 10110 on localhost, all nmea goes out of that, it's what feeds opencpn. No problem connecting in addition to opencpn, I just tried it in node red >
