Direct answer
RadioRA 3 fits many professional retrofit and whole-home lighting and shade projects; HomeWorks is intended for larger, more customized residences with deeper wired/wireless architecture, extensive keypad and shade requirements, and greater scale. Lutron's current system comparison should be checked when the project is specified because limits and supported devices evolve.
Do not choose by house square footage alone. Count loads and devices, review existing wiring, decide whether centralized panels or local dimmers are appropriate, identify shade and Ketra requirements, define integration and keypad aesthetics, and allow for future expansion. RadioRA 3's Clear Connect lighting communication does not depend on Wi-Fi, although apps, remote access, and third-party integration still use local network or internet services.
