Signal K MQTT Node Red

[jim321]

you cant publish from the actions tab..

   
i don't see any action to publish mqtt.
in fact i don't think op can publish mqtt at all you need to do it in node-red


 you can only have one "ws"web socket so delete any others and change user pass in the ...mqtt ..NODE...select the pencil choose localhost 1883 and in security your user and pass  to be same as openplotters mqtt
