@brainwave9 released a SiriProxy Plugin that allows you to control XBMC with Siri.
Currently, only two commands are supported:
- “XBMC” can be used to test if everything is set up correctly. Siri will respond with ”The XBMC interface is up and running”.
- “Play [TV Show]” will play the first unwatched episode of this show.
You can download the plugin here.
