I'm thinking of purchasing the Harmony plug-in, but have one question.

Is there feedback for the IR commands from a Harmony remote or hub? Will HS3 know which command(s) was sent by the remote/ hub to a device. For example, if I have an activity on my remote to watch DVD. It'll turn my TV, Stereo, and DVD player on and set the correct input channels as well. Will HS3 know when I press the Play button or Pause button the remote? I'd like to control my lights in the room based on if the movie is playing or not. If I press Play the lights dim or if I press Pause the light brighten
