RadioRA 2 to RadioRA 3: can I keep my keypads and dimmers?

The short answer. Yes, most of it. Lutron publishes a compatibility list for moving from RadioRA 2 to RadioRA 3, and it keeps the Maestro dimmers and switches, the Seetouch keypads, the Pico remotes, the occupancy sensors and the Sivoia QS shades. The main repeater and the connect bridge are replaced by a RadioRA 3 processor, and a short list of older parts has to be swapped. IntegrateIT, a Lutron Certified Dealer in Overland Park, reads your system against that list before anyone quotes a change.

If you have a RadioRA 2 house, the useful way to think about RadioRA 3 is as a new brain for the devices you already own, not a new house. This article walks through what Lutron lists as staying, what it lists as going, the way a conversion is done, and the questions to ask before you agree to anything. Every compatibility statement here comes from Lutron’s own support pages, and we read the current version of those pages before we advise on a house.

What stays on the wall

Lutron’s compatibility article lists these RadioRA 2 devices as working with a RadioRA 3 processor:

• Maestro dimmers, switches and fan controls, all models.
• Seetouch wall keypads, hybrid and non-hybrid, all models, and the Seetouch tabletop keypads.
• Pico wireless controls, all of them.
• Radio Power Savr wireless sensors, ceiling and wall mount.
• Plug-in lamp dimmers and plug-in dimming and switching modules.
• Sivoia QS and QS Triathlon shades, LMJ RF modules and the Lutron Wireless Thermostat.
• The Auxiliary Repeater, the Wireless Repeater and the Visor Control Receiver.

That is most of what a family touches. The keypad by the bed, the dimmer in the dining room and the shades on the west wall are all on the list. (A note on the wallbox power modules: Lutron lists them as compatible only with Lutron Designer 23.7 or higher, so that one is a check, not an assumption.)

What gets replaced

RadioRA 2 part	What Lutron says	Lutron’s named replacement
Main Repeater and Connect Bridge	Not compatible	The RadioRA 3 processor
Grafik T dimmers and switches	Not compatible, all models	Sunnata or Maestro
Grafik T CL hybrid keypad	Not compatible, all models	Sunnata or a Seetouch hybrid keypad
Single zone HVAC controller, TouchPro thermostat, Seetemp	Not compatible	The Lutron Wireless Thermostat

Lutron’s upgrade notes add one more thing worth knowing: a direct replacement for Grafik Eye modules is not available within the RadioRA 3 family, and multi-zone controls such as the Grafik Eye QS may need several RadioRA 3 devices. The conversion software lists the devices it cannot convert in your own file, and that is the list that matters.

The radio question

Owners often ask whether the two systems talk the same way. Lutron’s upgrade notes say that a device which cannot be converted is replaced with a Clear Connect Type A device or a Sunnata RF device, which Lutron labels Clear Connect Type X. What matters for you is practical: Lutron states which of your devices the new processor accepts. You read the compatibility list and replace what is on the not-compatible side of it.

How the move is done

Lutron describes the upgrade as a conversion, and the order matters:

1. Read the file. The RadioRA 2 project file is opened in Lutron’s RadioRA 3 software, which converts it and lists every device that cannot be converted.
2. Swap the brain. The processor replaces the main repeater and the connect bridge. Lutron’s guidance is to take the old main repeater off the network while the processor is set up, not to run both.
3. Keep the devices. Lutron says RadioRA 2 devices do not need to be factory defaulted, and that their activation information is saved when the project is converted.
4. Replace the short list. The parts on the not-compatible side get their replacements, and newly added devices are activated in the new project in Lutron Designer.
5. Check the Picos and sensors. Lutron notes that a Pico or sensor still paired with the RadioRA 2 system has to be removed from that system or factory defaulted.
6. Test every keypad. Press each button and run each scene before the job is closed.

Lutron’s upgrade pages do not address wiring or wall boxes, so we do not promise anything about them here; we check them at the wall. This is also a different question from the one in our other Lutron piece. (Choosing between RadioRA 3 and HomeWorks is a buyer’s decision made before the walls are built.) Yours is a house that already exists.

Why move at all

The honest answer is that some houses should not. If your RadioRA 2 system works, the keypads are labelled correctly and nobody in the family complains, a conversion is a choice, not a repair. We say so on the walk. Reasons an owner might move include not wanting to depend on the main repeater, wanting Sunnata devices in a room being remodeled, or adding something and wanting the current processor under it. If the integrator who programmed the house is gone, the project file is the first thing to find, because Lutron’s conversion starts from it. (The order we fix an inherited system in.)

Is RadioRA 2 going away?

You will see this asked everywhere, and we will answer it the plain way: we have not found a Lutron notice we can cite, so we do not give you a date. What Lutron has published is a conversion path and a compatibility list, which is the evidence that matters for a decision today. If a distributor or an old integrator gives you a date, ask for the Lutron document it came from.

What to ask before you agree to a quote

• Was my RadioRA 2 project file read, and can I see the list of devices it could not convert?
• Which compatible devices are staying, and which replacements are being added in their place?
• Will the old main repeater be removed from the network, and who owns the new project file afterwards?
• Are my shades, Picos and sensors included in the test, or only the lights?
• Was the scope set after someone visited the house, or from a phone call?

If the system also feeds a Control4 or Crestron controller, ask what that controller sees after the change. (Lutron service, for systems that already exist.)
