Lutron is pretty conservative when it comes to range. They do however have 2 products which can be used to extend the range another 30 feet. They have a dedicated extender for Caseta ( PD-REP-WH) and then the plug-in dimmer (PD-3PCL) which can do double duty as a dimmer and extender. According to the faq’s on casetawireless.com these two can be placed in series to extend the range to 90 feet, don't know of anyone doing this though, was under the impression that you could only add one extender, but this shows otherwise - https://www.casetawireless.com/faqs
