Jason - AWESOME customer support. I've installed your latest and was able to set everything up with the XBMC Harmony profile (I'm using Plex actually though). I was also able to program the wake button (where I got an error before). I enabled sleep detection and everything is working perfectly.
Right now I have Plex suspend the PC after 15 min if no one has touched it. This works well enough, but has anyone found a way to have Harmony/Flirc issue a suspend command when I hit the Activities off button? Something similar to what I have now where when I start my Plex activity, I have it send the new Wake key.
