I have an external Freeboard Dashboard that I need to talk to a remote Node-Red server. Using the built in Node-Red-Dashboard is not an option.

I cannot get Freeboard to recognize the Node-Red server as a JSON source. I have made sure my Freeboard installation works by using http://ip.jsontest.com.

I have checked the header and output of the Node-Red server but still no luck.

Node-Red Header: http://10.0.3.3:1880/hello http://ip.jsontest.com
HTTP/1.1 200 OK HTTP/1.1 200 OK
X-Powered-By: Express Access-Control-Allow-Origin: *

Connection: keep-alive Server: Google Frontend

Node-Red Page Source: {"Signal" : "3"}

ip.jsontest.com Page Source: {"ip": "99.140.82.10"}

Help.

  • Explain what you mean by "External Freeboard Dashboard"? Where is Freeboard running compared to where Node-RED is running? – hardillb May 17 '21 at 22:01
  • What I mean by external is a separate server from node-red. Node-red has its own dashboard but I don't want to use that. – Marc May 18 '21 at 23:49
