SignalK - NMEA 2000 data sharing, Battery, Engine and Fuel flow data - Hits and Tips - Boat Projects 

Glad it was a helpful video, I’m guessing the Garmin will be similar. Let us know how you get on. It would be interesting to know if the are any differences between brands in terms of setup.

Many thanks for your comments

Many thanks for your comments. Can you give me a bit more info about what you want to do with the data after? You can store anything in SignalK into a database and then use that.

@@BoatingwiththeBaileys I am mainly looking to do data visualization, but I want to do as much of the work as possible myself to learn about the protocol, the data, and so on. I have been looking for information on nmea 2000 but it is a bit hard to find since it is a closed standard. I would appreciate any recommendations for stuff to read.

I’ve not read into the NMEA2000 protocol that much myself, my focus has been getting systems talking to each. Are you running OpenPlotter or similar as that comes with Grafana which is great for data visualisation. InfluxDB is also bundled with it so you can record everything here and then export

@@BoatingwiththeBaileys I have not got that far yet but I have been looking at signalK, OpenPlotter, and some other stuff. I just wanted to know if there might be some other resources that could be educational 🙂

@@BoatingwiththeBaileys I was mainly thinking about books or articles though.

Hi, Not really as it comes as part of the OpenPlotter software and is ready to go. What system are you running and what data do you want to get into SK and i can try and help you. I've got other videos showing settings up various parts. I think i can help you get going.

@@BoatingwiththeBaileys hello, I am also looking for a shunt connectable to the nmea2000 or to the GPIO of my raspberry PI5 to display with Signa K the battery data (Volt, current, etc.) could you direct me to a product. I really appreciate your tutorials even though they are not in French. THANKS 👍

@Fred-Carpe_diem Hi, thanks for your comments. I would go with Victron kit, it's not directly connectable to NMEA without additional kit but if you have a Pi onboard then you can Bluetooth to it with a SignalK plugin and then send that data on as I do

@@BoatingwiththeBaileys Merci

Hi, do you mean the SignalK to NMEA2000 script? If so, yes thats an app avilable from the app store to change SK Keys back into NMEA 2000 data that the Axiom can understand. No multiplexer in the NMEA 2000 network, its not required. Fuel and engine data is from a device i made, thats also covered on the channel.

Hi, I believe its reached the final phase of testing, however i've not been provided with a date.

Thank you and Merry Xmas

Hi, Is this on your SignalK setup or on the Garmin? If its SignalK, can you let me know the path name and I should be able to help you. For example mine is something like 'electrical.batteries.House.voltage', so all I needed to type into the NMEA 2000 plugin was 'House' and it is case sensitive. For engine, I had called my 'main' in some paths and in others engine, so I changed them all to be engine and then just added that to the plugin. If I've not understood your question correctly, let me know.

@@BoatingwiththeBaileys Good morning, you understood it correctly. Just more details of my network. Im running to raspberry pi's. One as SIC (ship information center) including AVNav, openplotter, sensors, etc. the other one is our PIC (Power information center) running venus os with monitors all Victron equipment. Basically I'm having a NMEA 2000 (micro c) Garmin network including all the Garmin staff like plotter, auto pilot, AIS, radar ....The engine is a Volvo Penta connected to NMEA 2000 by YachtDevice. As far as I understand the network, some Garmin's are still using the NEMA 0183 to connect. Venus OS delivers it's data via the Venus Plugin in SignalK. I "believe" that the plugin is such delivers data using the signalk protocol ... right? So the NMEA 2000 plugin would be perfect to distribute all victron data to the network. In SignalK, data browser the ID for the main battery is "electrical.batteries.289.voltage". Putting this ID "289" in the NMEA 2000 plugin doesn't bring any data to the network. On the Garmin Plotter checking the NMEA 2000 network / devices I can see all the Garmin stuff and YachtDevice. An additional component with converts NMEA 2000 to IP. Sorry for being so comprehensive, but I hope that you get a clearer picture of my setup. Br, Otto

Really sorry - i missed the reply to this message. Did you get this resolved? I think you are correct on the incoming data being in the SK format, thats the case for my SmartShunt. I think the approach you have taken with the ID sounds correct, thats how the code should be picking things up and sharing it. Do you see any data in the SignalK log against the PGN's as i did?
