An ESP32-based controller for a kegerator
The controller adverstise itself with mDNS as kegtor-XXXXXX.local. where XXXXXX are the last 6 hexdecimal digits of its MAC address (to avoid conflicts with multiple controllers). You can browse to http://kegtor-XXXXXX.local./ to get an minimal HTML UI.
I also have a bitbar plugin for macOS users.
In theory any software that works with Flite controllers (display or headless) should also work with this controller as long as it is possible to configure the URL to access the REST API.
