RadioRA 3 can integrate with existing RadioRA 2 and RA2 Select lighting systems, with some device limitations, while also supporting compatible wireless shades through a central processor. Installers can configure and monitor the system from the Lutron app, and local switches and dimmers continue to operate if the internet connection is lost.

Place the wireless processor in a central location, using Power over Ethernet and a suitable mounting option to support RF coverage throughout the home. Keep each RF dimmer within 75 feet of the processor, with at least two other non-battery-powered RF devices within 25 feet of each dimmer, and consider pairing two processors for larger systems.

RadioRA 3 PRO LED dimmers and primary neutral switches require a neutral wire, while companion dimmers and switches use screw terminals and do not require a neutral wire. The processor receives power over Ethernet (PoE) through a compatible switch or included injector, and an internet connection supports initial setup and periodic firmware updates.

RadioRA 3 supports multi-location dimming by pairing a primary RF dimmer with up to four companion dimmers, allowing one light to be controlled from as many as five locations. For future expansion, the processor supports upgrades from compatible legacy systems, and two processors can be paired to increase capacity and coverage for additional RF devices, legacy devices, and wireless shades.
