Lutron RadioRA 3: what it is, what it costs, and who it's for
RadioRA 3 is Lutron’s wireless whole-home lighting control system — dimmers, Sunnata keypads, and motorized shades on one processor, installed without opening walls. It supports up to 200 devices, making it the standard choice for Phoenix-area homes. Ideal Automation designs and installs RadioRA 3 as a Lutron Diamond Dealer.

How does RadioRA 3 work?
A RadioRA 3 system is built from four pieces: a processor (the brain), in-wall dimmers and switches that replace your existing ones, Sunnata keypads that replace banks of switches with labeled scene buttons, and optional motorized shades. They talk over Clear Connect — Lutron’s dedicated radio protocol that doesn’t share airspace with your Wi-Fi, which is a big part of why Lutron systems don’t drop devices the way Wi-Fi bulbs do.
Because everything is wireless, RadioRA 3 is the retrofit king: we convert finished Phoenix and Scottsdale homes to whole-house lighting control in days, with no drywall work. Scenes (“Entertain,” “Movie,” “Goodnight”) live on keypads, the Lutron app, schedules, or your whole-home automation system.
RadioRA 3 vs. RadioRA 2 vs. Caséta
The three names get tangled in search results, so here is the honest breakdown:
| RadioRA 3 | RadioRA 2 | Caséta | |
|---|---|---|---|
| Status | Current generation (2022–) | Previous generation | Current, entry-level |
| Device limit | 200 | 200 | ~75 |
| Keypads | Sunnata (touch, engravable) | seeTouch | Pico remotes |
| Best for | Whole homes today | Existing installs | A few rooms |
| Upgrade path | — | Processor upgrade to RA3 | Grows into RA3 |
| Installation | Dealer-installed | Dealer-installed | DIY or pro |
If you own RadioRA 2 today, the practical takeaway: your investment isn’t stranded. The RA3 processor speaks to legacy Clear Connect devices, so we can modernize the brain and keypads while keeping dimmers that still serve well.

What does RadioRA 3 cost installed?
RadioRA 3 prices scale with device count, which makes budgeting refreshingly linear — the quote is the sum of the rooms you choose. Three typical scopes:
- Starter scope — a processor plus the great room, kitchen, and exterior lighting: from about $8,000 installed.
- Whole home — dimmers throughout, keypads at main entries and bedsides: commonly $15,000–$40,000 for Phoenix-metro homes.
- With shading — motorized shades priced per window, roughly $1,000–$3,000 each depending on size and fabric.
Every quote is fixed and itemized per device, so you can trim or grow scope room by room and see exactly what each room adds. Systems also expand gracefully later — a common path is starting with the main living areas and adding bedrooms the following year.
Serving Phoenix, Scottsdale & Paradise Valley
Most of our RadioRA 3 work is retrofit: 1990s Arcadia and Moon Valley homes getting whole-house control without construction, and North Scottsdale houses pairing RA3 dimming with automated shades on big west-facing glass. Design, installation, and programming all come from our Phoenix team.
We regularly work in Arcadia, the Biltmore corridor, North Scottsdale, Desert Ridge, DC Ranch, Silverleaf, McCormick Ranch, and the communities around them. Not sure if you’re in our area? See our full service area or call us — we’ll tell you straight.

RadioRA 3 questions, answered
What is Lutron RadioRA 3?
RadioRA 3 is Lutron’s current-generation wireless lighting control system for whole homes, introduced in 2022. One processor coordinates up to 200 dimmers, switches, Sunnata keypads, sensors, and shades over Lutron’s Clear Connect radio — reliable, wall-friendly, and installable in finished homes.
How much does RadioRA 3 cost?
RadioRA 3 is priced per device, so cost scales with the rooms you include. A main-rooms starter package typically begins around $8,000 installed; whole-home systems commonly run $15,000–$40,000, with motorized shades adding roughly $1,000+ per window. As a Diamond Dealer we quote a fixed, per-device-itemized price after a walkthrough.
RadioRA 3 vs Caséta — what’s the difference?
Caséta is Lutron’s entry system, capped around 75 devices with basic keypads — great for a few rooms. RadioRA 3 scales to 200 devices, adds Sunnata keypads with custom engraving, wider shade support, and richer scene control. For whole homes, RadioRA 3 is the appropriate tier.
Can RadioRA 2 be upgraded to RadioRA 3?
Yes. The RadioRA 3 processor supports Lutron’s legacy Clear Connect devices, so many existing RadioRA 2 dimmers can remain in service while the processor, keypads, and problem areas are modernized — a phased upgrade rather than rip-and-replace. We evaluate your device list and quote both paths.
Does RadioRA 3 work with Crestron, Control4, and voice assistants?
Yes. RadioRA 3 integrates natively with Crestron and Control4, plus Alexa, Google Assistant, Apple HomeKit, Sonos, and Ketra. In our projects it usually runs the lighting layer inside a larger automation system while staying fully usable from its own Lutron app.
Do I need a dealer to install RadioRA 3?
RadioRA 3 is a professionally installed system: design, programming, and setup run through Lutron-trained dealers. That matters for load engineering, flicker-free LED dimming, and keypad programming. Ideal Automation is a Diamond-tier dealer based in Phoenix — Lutron’s top program level.
