Lutron Caseta is wireless, requires no neutral wire at switches, scales to ~75 devices, installs in any home including retrofit, and costs $500–$5,000 for a typical home. Lutron RadioRA 3 is hardwired, requires a neutral wire at every switch (planned during electrical rough-in), scales to 200 devices per system, includes premium engravable keypads throughout the home, and integrates with Control4, Savant, and HomeKit. For new construction where the rough-in can be planned, RadioRA 3 is the superior product — premium user experience, unlimited scenes, and whole-home coverage from every keypad. For retrofit or budget-conscious projects, Caseta provides excellent performance at a fraction of the cost. RainFire Builders includes neutral wires at all switch locations as a standard new construction practice, ensuring RadioRA 3 is always an option.
