Finished-home retrofits
Wireless controls and shades can reduce new control wiring, subject to neutral availability, load compatibility, Ethernet access and required electrical work.
Professional wireless lighting, shade and scene control
Lutron RadioRA 3 Whole-Home Lighting Control
Lutron RadioRA 3 brings professional lighting and shade control to existing homes without a centralized lighting panel. Sunnata RF controls communicate through Lutron Clear Connect, while the processor, Lutron app and supported integrations coordinate scenes, schedules and remote access. Davis Audio & Video designs the RF, electrical and network foundation for dependable room-by-room operation.
System type Professionally programmed wireless lighting and shade control
Published scale Up to 400 devices with paired processors under current Lutron system limits
Primary controls Sunnata RF, compatible Maestro and seeTouch devices, Pico controls and Lutron app
Best use Existing homes, phased renovations and wireless whole-home projects
Integrator guidance
Lutron RadioRA 3 in a complete system designed by Davis Audio & Video.
RadioRA 3 sits between Caseta and HomeWorks. It supports professional PC programming, higher device capacity, integrations, window treatments and varied controls. Its wireless architecture is useful when finished walls should remain intact or a project will grow in planned phases.
Wireless does not mean design-free. The processor requires Ethernet and standards-compliant Power over Ethernet, while Clear Connect Type X and Type A devices follow different distance and repeater rules. Existing neutral conductors, LED compatibility, multi-location wiring, fixture loads, wallbox depth and RF obstructions must be verified before hardware is assigned.
Davis Audio & Video translates those requirements into straightforward control. A homeowner can recall keypad scenes, schedule lights, coordinate compatible shades, use the Lutron app and include supported RadioRA 3 commands in a broader Control4 or voice routine.
Where RadioRA 3 fits best
RadioRA 3 is strongest where professional control and expansion are needed without a full centralized HomeWorks architecture.
Room-by-room expansion
A properly planned RF layout can begin with priority rooms and grow, provided processor capacity and Type X mesh rules remain part of the original design.
Sunnata control upgrades
Touch dimmers, switches, fan controls and keypads provide a coordinated paddle aesthetic in more than 20 available colors and finishes.
Lighting and automated shades
RadioRA 3 can coordinate compatible Lutron lighting and window treatments through scenes, schedules, keypads and the Lutron app.
Selected RadioRA 2 migrations
Many compatible Type A devices can be incorporated into an upgrade, but excluded models and the existing database must be reviewed before promising reuse.
What RadioRA 3 adds to an existing home
Dedicated Clear Connect communication
Lutron controls communicate through purpose-built RF rather than relying on the homeowner's Wi-Fi for every dimmer, keypad and shade command.
Consistent Sunnata design
Dimmers, switches, fan controls and scene keypads share a coordinated look, light-bar language and compatible wallplate format.
Scenes and schedules
Keypads and the app can recall multiple lighting and shade actions, including timeclock events tied to clock time or sunrise and sunset.
Professional integration
Current Lutron support includes established automation, voice, audio, climate and security platforms, subject to each integration's current capabilities.
Planned scalability
Multiple processors can support larger projects when system-wide device limits, RF coverage and network architecture are engineered correctly.
Professional design
Why RF and load planning determine reliability
RadioRA 3 uses both Clear Connect Type X and Type A, and the rules are not interchangeable. Type X devices form a mesh but must remain within 75 feet of their assigned processor and within 25 feet of two compatible Type X devices. Type A devices use processors and repeaters with separate 30-foot and 60-foot limits. A Type A repeater does not extend Type X coverage. Davis Audio & Video plots both networks before final device placement.
Every controlled circuit also needs an electrical match. Sunnata RF controls may require a neutral, and LED performance depends on the fixture, driver, lamp, load size and selected dimmer. Davis Audio & Video documents each load, checks current Lutron compatibility guidance, confirms multi-location wiring and tests low-end and high-end performance rather than assuming every existing switch can be replaced with the same model.

Planning notes
RadioRA 3 design considerations
- Record voltage, fixture or lamp type, wattage, driver, neutral availability, multi-location wiring and expected dimming range.
- Assign processors and repeaters from measured device locations instead of treating all Lutron RF products as one coverage map.
- Provide a compliant home-run cable, switch or injector power, central mounting location and access for future replacement or diagnostics.
- Use clear scene names and deliberate button layouts so daily control is simpler than operating each circuit individually.
- Preserve the existing RadioRA 2 database and identify every proposed reusable device before converting or removing an installed processor.

FAQs
Product questions
What is Lutron RadioRA 3?
RadioRA 3 is a professionally installed and programmed Lutron system for wireless lighting, compatible shades, scenes, schedules, app control and supported integrations. It uses Clear Connect RF for system devices and a wired Ethernet processor for programming, app and integration services.
How is RadioRA 3 different from Caseta?
RadioRA 3 offers professional PC programming, substantially greater system capacity, Sunnata RF keypads, broader device selection and more advanced professional integrations. Caseta is a smaller app-configured platform intended for simpler projects.
How is RadioRA 3 different from HomeWorks?
RadioRA 3 is optimized for professional wireless installations and retrofits. HomeWorks supports much larger systems, wired QS links, centralized panels, additional luxury keypads and Lutron's broadest native lighting and shade options.
Does RadioRA 3 use the home's Wi-Fi?
Dimmers, keypads and compatible shades communicate with Lutron Clear Connect RF rather than Wi-Fi. The RadioRA 3 processor still requires a wired Ethernet and PoE connection to the home network for setup, app services, updates and integrations.
Will RadioRA 3 work if the internet goes down?
Lutron states that local device operation continues during an internet outage. Cloud-dependent remote access, voice services and some integrations may be unavailable until service returns. The local network and PoE equipment must remain powered.
Can RadioRA 3 reuse RadioRA 2 devices?
Many current Type A devices are compatible and Lutron provides a database-conversion workflow, but exclusions apply. Davis Audio & Video audits installed models and preserves the original project before committing to reuse.
Do Sunnata RF controls require a neutral wire?
The current Sunnata RF PRO LED+ dimmer and several other Sunnata RF controls require a neutral. Compatible Maestro RF options may fit some no-neutral conditions. Each load and wallbox must be checked before model selection.
Can RadioRA 3 integrate with Control4 and Sonos?
Lutron currently lists Control4, Sonos and numerous other professional, voice, audio, climate and security integrations. Davis Audio & Video verifies current driver or account requirements and tests the specific commands included in the project.
