SK / Node Red / Digital Switching Maretron DCR-100
I am traying to get digital switching working via SignalK and Node Red.
I have installed the following plugins:
- @signalk/signalk-node-red (operational)
- signalk-n2k-switching (configured - all on)
- signalk-maretron-proprietary (configured - all on)
I try to set electrical.switches.bank.11.3.state on a Maretron DCR 100
My node red dashboard:
[{"id":"89afe19b71f08c67","type":"tab","label":"Flow 2","disabled":false,"info":"","env":[]},{"id":"fc56aacc.889408","type":"signalk-subscribe","z":"89afe19b71f08c67","name":"","mode":"sendAll","flatten":true,"context":"vessels.self","path":"electrical.switches.bank.11.3.state","source":"","period":1000,"x":280,"y":120,"wires":[["4e791c49bf5180ba","a8c1e2500c85d9a1"]]},{"id":"64686842.76ea18","type":"signalk-send-put","z":"89afe19b71f08c67","name":"","path":"electrical.switches.bank.11.3.state","source":"","x":900,"y":120,"wires":[]},{"id":"4e791c49bf5180ba","type":"debug","z":"89afe19b71f08c67","name":"debug 4","active":true,"tosidebar":true,"console":false,"tostatus":false,"complete":"payload","targetType":"msg","statusVal":"","statusType":"auto","x":580,"y":220,"wires":[]},{"id":"a8c1e2500c85d9a1","type":"change","z":"89afe19b71f08c67","name":"","rules":[{"t":"set","p":"payload","pt":"msg","to":"1","tot":"num"}],"action":"","property":"","from":"","to":"","reg":false,"x":570,"y":120,"wires":[["64686842.76ea18","ba1d0728653a5e38"]]},{"id":"ba1d0728653a5e38","type":"debug","z":"89afe19b71f08c67","name":"debug 5","active":true,"tosidebar":true,"console":false,"tostatus":false,"complete":"false","statusVal":"","statusType":"auto","x":880,"y":220,"wires":[]}]
The error message I get is:
put error 400 there are multiple sources for the given path, but no source was specified in the request
If I change $source in signalk-sent-put to "node-red" than I get:
put error 405 PUT not supported for electrical.switches.bank.11.3.state
Any hint would be helpful.
Thanks a lot!

Can you show what the switches look like in the Data Browser?
Hello Scortt, thanks for your quick reply.
Here the requested information
Try making $source NGT1.73
Thank you for your feedback. I did this for the signalk-sent-put node.
Looking at the flow I see "pending" for the signak-sent-put followed by this error in the debug log:
put error 502 Did not receive change confirmation
Console out is:
[error] [signalk-send-put:64686842.76ea18] put error 502 Did not receive change confirmation
And the switch doesn’t actually “switch”?
Have you confirmed that you’re able to send n2k messages at all?
What’s you n2k Data Connection look like?
Yes, this is correct, it does not switch.
I am using a RPI 4B with kernel 6.6.31+rpt-rpi-v8.
node v18.20.4, SignalK 2.8.3, canboatjs /dev/ttyUSB0, 115200 baud USB-NGT1 N2k Interface from Actisense with latest FW
I used the same NGT1 for TimeZero Professional on a Windows 10 machine and it was able to sent XTR to my Furuno autopilot.
Is there a way I can test that N2k data is transmitted under RPi/SK?
I have a 2nd workstation on the bus with a own NGT1 where I can read N2k using Actisense NEMAReader and I also have a Maretron IPG-100 where I use the N2KAnalyzer.
Thank you so much,
Dirk
I think you need to enable send for pgn 127502 using the Actisense windows software.
Ok, will try and give feedback
I enabled pgn 127501 and 127502 for TX. I verified this with another PC an "update from hardware" showed the setting enabled. Nevertheless the error is still the same.

Hmm
Let’s try turning on debug for the n2 switching plugin.
Also turn off the Maretron plugin for now
After disabling the Maretron Plugin I see a lot of this messages in the Log:

I wonder if you need to enable send for 126208
sorry I didn't think f this before... enable debug for
signalk:actisense-outThe 126208 TX was enabled by default. I also enabled 126208 RX now.
Is Jeremy out there?!

It does not switch - the additional actisense log above
