Direct answer
Sunnata RF is a family of wireless wall controls and keypads used with systems such as RadioRA 3, emphasizing a familiar control shape, illuminated touch-oriented dimming, configurable buttons, and retrofit flexibility. Palladiom is a premium architectural keypad and control family associated with HomeWorks, with different material, profile, finish, and design options. They are not simply two cosmetic faceplates for the same project architecture.
Choose the lighting system first, then select controls that match its supported devices, wiring, load strategy, engraving, finish, and interior-design requirements. A mixed estate may use more than one control family, but every keypad should remain understandable to guests. Sources: Lutron Sunnata and Lutron Palladiom for HomeWorks.
