write and read SignalK Path - Spidgrou - 2021-05-03
Hi guys,
probably it is only my problem, but i need help.
I use node-red to write a path in SignalK. NO PROBLEM
Then I triy to read.... nothing.
I can't understand where is my mistake.
Any help is appreciate.
Code:
[{"id":"3332bda9.e31492","type":"tab","label":"Flow 1","disabled":false,"info":""},{"id":"8fb41530.5ab9d8","type":"change","z":"3332bda9.e31492","name":"Test","rules":[{"t":"set","p":"payload","pt":"msg","to":"100","tot":"num"},{"t":"set","p":"topic","pt":"msg","to":"test","tot":"str"}],"action":"","property":"","from":"","to":"","reg":false,"x":350,"y":80,"wires":[["bed36ea1.85c9d"]]},{"id":"bed36ea1.85c9d","type":"signalk-send-pathvalue","z":"3332bda9.e31492","name":"","source":"","meta":"","x":650,"y":80,"wires":[]},{"id":"2821b233.65808e","type":"inject","z":"3332bda9.e31492","name":"","props":[{"p":"payload"},{"p":"topic","vt":"str"}],"repeat":"5","crontab":"","once":false,"onceDelay":"1","topic":"","payload":"","payloadType":"date","x":170,"y":80,"wires":[["8fb41530.5ab9d8"]]},{"id":"b7be7b4d.1f36a8","type":"signalk-subscribe","z":"3332bda9.e31492","name":"","mode":"sendAll","flatten":true,"context":"vessels.self","path":"test","source":"","period":1000,"x":160,"y":160,"wires":[["f362dc99.127a6"]]},{"id":"f362dc99.127a6","type":"debug","z":"3332bda9.e31492","name":"","active":true,"tosidebar":true,"console":false,"tostatus":false,"complete":"false","statusVal":"","statusType":"auto","x":440,"y":160,"wires":[]}]Thanks

Pretty sure this came up before, it does work, have a look in the data browser and you should see test. But istr the node-red node won't see signalk data which is created by node red.

Yeah, I confirm that I can see in browser... But why I can't see on node red again?
I see also very well in mqtt, but I would like to continue with signalk.

Not sure why it's programmed that way, maybe to stop loops. Why would you need to though? If you want to something to a delta in node red why not do it when you create it instead of sending in node red then reading again in another flow?

Try setting the source in both send and subscribe.
PS I find unformatted node-red flow JSON really hard to read. Consider pretty printing/formatting it when posting it.

Hi,
yeah IT WORKS.
Probably nodered needs a different source from his name.
If I don't insert any Source, Nodered put itself as source.

yeah IT WORKS.
Always fun to see what's going on deeper down, but still can't see why you would ever want to read a delta you just wrote in node-red..
Signalk on slack would be the place to ask why it's hard coded like that, guessing to prevent loops.
