Not seeing NMEA2000 data in Signal K

[Kokomo]

I have an Ekrano GX with Large Image, running SignalK. Under the Signal K data browser, I see most of the NMEA 2000 data from devices on the network, but some is missing. I see GPS data but no other Garmin data.

I have a NMEA2000 data logger on the network and it captures all of the engine data (provided by Maretron J1939 to NMEA2000 device), but I don't see any of this in Signal K.

How do I configure Signal K to see other NMEA2000 device data, that can then be logged in Saillogger?

Hi, thank you for the note. I wonder if these are PGNs not recognized by Signal K. But it sounds like too many things are not recognized which doesn't sound normal. What kind of data can you see from NMEA 2000?

Related to that, can you search navigation.position and environment in Data Browser and send a screenshot of those as well the Summary screen of Signal K?
