Getting positional data to create a GPS device on the Cerbo Gx

Hi, I’ve got an AIS unit which can stream NMEA0183 data over IP. I have signalk receiving that, and I want it to show up as a device on the Cerbo GX. I have turned on the “signalk to nmea0183” plugin, and I’ve tried the “signalk to nmea2000” plugin. Both show data being succesfully processed in signalk. But no device shows up on the Cerbo GX. Is there any way I can confirm it’s receiving that data through the signalk-venus-plugin?

So I thought I’d try creating a virtual device in node red. But when I add the signalk subscription node, it just crashes node red. So then I tried using the version of node red embedded in the signalk system, but that doesn’t show any victron devices - I have tried enabling root access, allowing ip access to the dbus - still nothing showing. I don’t know where to look for errors on that.

I can’t win here. Would love some help to make any of these options work.
