How big of a room can RadioRA-SR cover?
Lutron modeled a “worst case” room, including construction techniques such as cement, metal studs, stone walls and foil wrap. It was determined that in this worst case world, a conservative range for RadioRA-SR devices is 30 feet. Therefore, RadioRA-SR should be installed in rooms where the maximum distance between any two RadioRA-SR devices (dimmers, switches, keypads, shades and interfaces) is 30 feet or less.
