RadioRA 3 can be an attractive next step for a home with RA2 Select or RadioRA 2, especially when new rooms, keypads or shading are planned. It is not safe to price it as a processor-only replacement without identifying the existing equipment.
First, identify which “RA2” you have
RA2 Select and RadioRA 2 are related but different systems. Note the main repeater or processor model, in-line dimmers and switches, keypad or Pico models, shades, and any integration equipment. Keep the original project information, app access and installer details where available. Do not factory-reset a working system to find out.
Check compatibility by exact UK part number
Lutron provides RadioRA 3 backwards-compatibility resources. Some earlier products can be used in an upgraded design, but others need replacement. Regional versions, frequency, wiring and software support matter. A generic claim that “all RA2 devices work with RA3” is not a reliable basis for a quote.
RadioRA 2 projects may have an extractable programming file; RA2 Select uses a different setup route. The access and documentation available on this specific property determine the practical conversion plan.
Make the upgrade plan room by room
- List the rooms and what must keep working throughout the change.
- Record each control, load type and shade; mark what is confirmed compatible, uncertain or due for replacement.
- Agree the new scenes, keypad functions, app access and any home-system integrations.
- Check radio coverage, network and processor power, plus the electrical work needed at each load.
- Price equipment, installation, programming, commissioning and handover separately.
If the existing system is unreliable, diagnose the underlying fault first. Replacing a processor will not fix an incompatible lamp driver or a wiring fault. If essential lighting is affected, use our safe fault checklist.
What does the upgrade cost?
The reusable-device count is the largest unknown. The Lutron cost guide shows current RadioRA 3 component examples, but it cannot turn them into an installed upgrade price without the inventory and site scope. A quote should state what remains, what is replaced and what happens if an assumed compatible device fails testing.
Request a RadioRA 3 upgrade assessment and send photographs of labels that are safely visible, your room list and any original files. Do not open live electrical panels.
