Overview

On the Widy, or any device running OpenWrt, the device's configuration is set using UCI, the Unified Configuration Interface. This is similar in spirit to the way that most routers have web interfaces that allow you to modify their configuration options. You can interact with the UCI system using two different UCI interfaces: one is the web interface, LUCI, and the other is the command line interface uci.

In each case, changes to the UCI options are written to a group of files located in /etc/config. The list of files looks like this:

# ls -l /etc/config
-rw-r--r--    1 root     root           724 Mar 16 22:33 dhcp
-rw-r--r--    1 root     root            62 Oct  1  2014 dropbear

Each config file covers one major aspect of the Widy's operation.

Q: What happens when you change /etc/config/file? Does it stay persistent?

Q: When and how does UCI override changes with defaults?

Q: How can I link UCI with the 3 slider buttons?
