no topic for incomming message #29

Open zero1974 opened 2 years ago

zero1974 commented 2 years ago

Hi all, first of all: amazing project!! Thanks for all the work done. I am new here and i deal with signalk and the node-red plugin since some weeks. I think i didn't understand how to create a topic witch is sent to signalk. I build a trigger and send temperature update via signalk-send-pathvalue. I made a screenshot also. I hope someone can help to fix the problem. Thanks a lot!!

I don't see a screenshot. Better yet, export your flow and post it here.

Many thanks for your quick response.

ok, i exported the flow and will paste it here. i modified it and the error "no topic for incomming message" is fixed. i forgot to declare the topic correctly...SORRY, i installed openplotter not so long ago... Now the flow works, but signalk cant xfer it to nmea2000 output. My goal is the following:

i would like to send data from my boat (nmea network and actisense NGT-1running on openplotter at raspberry 4 ) to my home-raspberry4 , running openplotter, too. So i have 2 signalk servers up. vpn things will be done in the future.

I want to test if it is possible to visualize the nmea2000 data from the boat at home, on my b&G Triton2 display, witch is connected to another NGT-1 by sending data from boat to my home signalk and trasform the data by using the plugin "signal-k to nmea2000" at home. The flow works now, but

  1. it connects to the local (boat) signalk server because of using the node-red predefined flows and
  2. in the data browser (boat pi) i can see : Path, Value, units, timestamp and source correctly, but behind the source value, witch is 1.1,(coming from node red) there is no pgn number in brackets available like other source entries have: e.g nmea2000.2 (127258). Further on, the source: "node-red" printed below have no keys like other sources have, for example the nmea2000 source with 4 keys.

i would be very! happy about some help or ideas or maby a link to get some more input.
I hope you can comprehend ..... Here is the exported code:

[ { "id": "ae7635f29dd78094", "type": "tab", "label": "Flow 1", "disabled": false, "info": "", "env": [] }, { "id": "604444910f84b34b", "type": "signalk-send-pathvalue", "z": "ae7635f29dd78094", "name": "SendToSigK", "source": "node-red", "meta": "", "x": 830, "y": 320, "wires": [] }, { "id": "7cee26dd8febc84f", "type": "inject", "z": "ae7635f29dd78094", "name": "manual trigger via timestamp", "props": [ { "p": "payload" } ], "repeat": "1", "crontab": "", "once": false, "onceDelay": 0.1, "topic": "", "payload": "", "payloadType": "date", "x": 210, "y": 240, "wires": [ [ "611b087fa2c6276c" ] ] }, { "id": "1d067e73554dacc5", "type": "debug", "z": "ae7635f29dd78094", "name": "", "active": true, "tosidebar": true, "console": true, "tostatus": true, "complete": "payload", "targetType": "msg", "statusVal": "payload", "statusType": "auto", "x": 840, "y": 160, "wires": [] }, { "id": "611b087fa2c6276c", "type": "function", "z": "ae7635f29dd78094", "name": "", "func": "msg.topic=\"environment.wind.angleApparent\";\nmsg.path=\"environment.wind.angleApparent\";\nmsg.source={\"label\":\"node-red\",\"type\":\"NMEA2000\",\"pgn\":130306,\"src\":\"35\"};\nmsg.$source=\"node-red\";\nmsg.payload=1.1;\nreturn msg;\n", "outputs": 1, "noerr": 0, "initialize": "", "finalize": "", "libs": [], "x": 580, "y": 240, "wires": [ [ "604444910f84b34b", "1d067e73554dacc5" ] ] } ]

Thank you very much!

The source will always be node-red in this case.

Why do you care what the source is?
