Just an update. I have successfully used a Niles IR repeater with the Lutron Spacer System. The reason I am doing this is because my Lutron Spacer dimmers and components are at a very large angle from the seating position and the projector is ceiling mounted. I have an IR sensor mounted on the wall directly in front of me near a corner so its not behind the screen. The IR sensor is connected to the Niles MSU250 repeater. Since I have four spacer dimmers mounted in a gang box I had to use a dual IR flasher and mount one on the right and the other in the left side of the box. I suppose I could have used a single blaster which is larger but the box is already pretty full.
