Kassi is a remote for the popular media center application Kodi/XBMC. It's a tool that lets you control the said media player from your web browser or any other application on your device. It gives you the capability to control XBMC from anywhere. This app supports both the official remote and the unofficial Frodo remote.

How does Kassi work?

First of all, you have to make sure that the "Allow program on other system to control XBMC" option is enabled. If you have multiple XBMC installations, then you have to make sure that the settings for the right one are correct.
