N2k data and Nemo Gateway as Data Source

[dmyachts]

100% of the data sources I want to use via Signal K is connected via NMEA 2000 (N2k). I have an Actisense gateway connected to my computer and I have a Nemo Gateway (see https://www.rosepoint.com/nemo-gateway/) from RosePoint Navigation that is connected to my network as well as to N2K. I can see all PNGs from all sources here so I know the information is on N2K and working.

I have pointed my Signal K server (OpenCPN instance) to the Nemo viat TCP/UDP and it receives all navigation information, but it is not displaying any information from my engine or my Victron Cerbo GX, I can see both of these data streams in the Nemo Gateway.

How do I get Signal K to recognize the PNGs from my engine and Cerbo GX?

Forgot to mention that my Signal K server is on a Raspberry Pi 4 which is connected to the network as well.

It's looks to me like that Nemo only outputs 0183 over tcp. You'll only get limited data that way.

You need a device that can output n2k data. https://github.com/SignalK/signalk-server/wiki/FAQ:-Frequently-Asked-Questions#how-do-i-integrate-with-nmea2000-can-bus

Also note that you can use signalk-venus-plugin to get data from your Cerbo. You'll get much more data and control that way.

Ok. I will connect to my cerbo. I have an Actisense NGT1 connected to my main computer on board. How could I point Signal K on my RP4 to that com port to pick up the info? I am using the Actisense to populate the navigation information I use in TimeZero as well as to output routes to my autopilot.

Maybe just get another one to connect to my RP4?

You can plug NGT-1 to your RPi, have SK convert the navigation information to 0183 and connect TZ to tcp 10110 on the RPi.

If TZ supports n2k over tcp in one of the well known formats we could do the same with n2k, except I don’t think we have yet support for that. Adding it should not be too much work, just not there yet I think.

Great idea. I will try this next time night am on board. Sent from Outlook for Android<https://aka.ms/AAb9ysg>

I am going to my boat in a week and will configure the RPi per above. My ultimate goal is to connect the Signal K data to Influx db using your plugin and then create dashboards in influx or grafana to ultimately be included in my web site. Point is for people to watch realtime data as i make my circumnavigation over a 5 year period. I will be cruising the Med this summer to prep this system. Thoughts?

I bought another NGT for the RPi and got the signal k server to recognize all the data. Tried to configure the Influxdb plugin, but Signal K responds that the config is not saved. Tried reinstalling SK Server, tried creating another instance on a separate micro disk, all the same. Not sure what I am doing wrong. Have watched many videos and read install but cannot get the plugin updated with server, token, bucket, organization.
