Has anyone managed to hack a Lutron Maestro IR so that they operate in different frequencies? I'd like to be able to control my 2 IR lutron wallplates independently, using my Logitech Harmony universal remote. Currently, both operate in the same frequency, and therefore I am limited in what I can do to program custom 'scenes'...

I don't think that you can do this. I believe you have to use the Lutron Spacer system if you want to use more than one switch in the same room independently.

Well, Im sure it is not designed to work this way, but I figure it is hackable :) May require soldering of course!
