The following section gives a general introduction to working with yunIO. The information described in the following section is a prerequisite for all subsequent sections.

Starting yunIO #

To access the yunIO Designer, enter the designer-URL in a web browser.
The URL pattern to access the yunIO Designer is http://[host]:[port]. Example: http://localhost:8077.

  • If the yunIO service runs on a local server, replace [host] with localhost.
  • If the yunIO service does not run on the same machine as the browser, replace [host] with the name or IP address of the host on which the service runs.
  • After the installation the yunIO Designer is accessible under the default port 8077.
    You can configure the port under Settings in the yunIO Designer.

Note: Make sure that the yunIO service is running and that the default port 8077 is not blocked by your firewall.
