What’s missing is how to push the info to a Virtual Device.
I have a VETUS E-line electric motor. The motor itself is not NMEA 2000 compatible, but VETUS supplies a bridge device as part of their touchscreen offering, converting some messages from VE.Can to NMEA2000. The screen has an NMEA 2000 input.
Unfortunately, it does not work out of the box, perhaps some misalignment in PGNs, who knows? But there is another route; I also installed SignalK on my CerboGX, and I can see the motor data, such as revolutions, gear position, and temperature of the motor and controller.
So I first created the Virtual Device and set it to Motor, and marked RPM.
I then added a SignalK subscribe node and added the path to the Motor RPM, and then Publish. Unfortunately, in my case, Node-Red becomes unresponsive, but I was able to do some more research in Node Red safe mode.
I did find a Victron Input node, I can’t recall the exact name; I need to go back to the boat then. However, I was unable to find the Virtual Motor to push the Signalk data to. Curious to learn how others did it.
edit: I think not being able to find the virtual motor may have to do with this thread, I ran into the same issues and warnings with Node Red on 3.6. Will try again this week!
