Issue with Signal K to NMEA2k

[superstar76]

I've used Ruuvi tags and Victron Cerbos on a number of installs, and then use Signal K to get the Ruuvi temp data onto NMEA.

However, on this particular install, for whatever reason I cannot get the data from Signal K to NMEA.

I have installed the Mapper Plugin, and have mapped the Ruuvi data to the correct points, and they show up in the data browser:

Turned the temperature PGN on in Signal K to NMEA Plugin:

Have tried it with Source blank and filled in, have tried Resend as both 0 and 1.

But they do not come on the NMEA network once this is done:

I do see this, and wonder what this error is and how to resolve:

Any ideas?

I found the issue with the error on the VE CAN socket. It seems with Cerbo 2's that the interface is "can0", but needs to be "vecan0". once amended error is gone. This did not resolve the issue however.

You have the wrong thing for "Source" in the plugin config. Leave that blank.

Yep. Solar is communicating NMEA data from Victron to the NMEA network and displayed on CZone:

I want to make sure n2k is working in Signal K. In the Signal K Data Browser so you see any data from other n2k devices?

[superstar76]

Ah, that appears to be the problem. No N2k data from other devices in SK. We're receiving data from the Cerbo to the N2k network, but there appears to be a breakdown between SK and the N2k network. What could cause this?

@sbender9, I went to another boat and tried today... No joy...
Mapped

N2K on

Not coming up in NMEA Reader

All data is communicated from N2K network on this boat to Signal K, not as we see the issue on the other boat. So now not sure that that is the issue. Again this boat has a Cerbo 2.

[sbender9]

If you are not seeing n2k data on your boat, then sending is definitely not going to work. But is it strange that sending is not working on the other boat.

I don't think I have actually tested this, but I'm pretty sure others are doing it.

I will test on my Cerbo MK1 tomorrow and confirm.

Are you on the Signal K Discord? Maybe we can find a time to do some realtime troubleshooting?
