changing dia web interface

This can be done by editing the dia.yml file.  Inside of it there will be a presentation section.  You can edit the 'page' value.  

In the example below we are specifying the path of 'idigi_dia'.  So the end request will look like this (IP address will vary of course)
http://10.10.20.122/idigi_dia

presentations: 
  - name: web0
    driver: presentations.web.web:Web
    settings: 
        page: "idigi_dia"


after making the change you will need to upload the new dia.yml configuration to the Digi.
