[SOLVED] Plex and Chromecast

I have the Plex SmartApp installed and works fine for most of my devices. What I found is that it does not register my chromcast devices. Is this a limitation on Plex?

Basically I am trying to get the status of Plex when casting to my chromecast so I can create a piston to dim my lights when playing.

Ideas?

I got what I was looking for using the Google Cast Service Manager SmartApp.
