It is no more complicated to program 50 devices than it is one device. Caseta programming is so easy using the app that pretty much anyone can set up a very functional automation system that is more than adequate for the vast majority of people. I am sure lutron placed the 50 device limit and on record says that caseta is for room control and not whole home control to appease the integrators who up to now are the majority of this business. That is pure BS...the caseta system works very reliably in my 4000 sq foot home and it links with my alarm system...all programming done through my iPhone. Hopefully when homekit etc take off lutron will see that the DIY market for this stuff is much more important than the integrator market and remove the silly restrictions from caseta.
