Settings
OpenPlotter Signal K Installer app installs the server using port 3000 by default. To access the web administration panel of the Signal K server, you can use this URL from the browser included in OpenPlotter:
http://localhost:3000
Or this one from a browser running on any computer connected to the same network:
http://openplotter.local:3000
If you set the port 80 instead the default port 3000, the URLs would be:
