Which Lutron RA2 Select and RadioRA 3 systems should I buy?

RA2 Select and RadioRA 3 are the Lutron systems above Caséta. Both use Clear Connect RF rather than Wi-Fi. RA2 Select is built around a main repeater. RadioRA 3 is a professionally installed system built around an all-in-one PoE processor, and it scales to 400 devices with paired processors.
