The Lutron RRK-SEL-REP2-BL RA2 Select Main Repeater Hub is the smart automation heart of a Lutron RA2 Select lighting and shading system. This compact wireless repeater hub enables centralised setup, control, and monitoring of up to 100 wireless devices, including dimmers, switches, Pico wireless remotes, sensors, and motorised shades — all from your smartphone or tablet using the intuitive Lutron App.

Designed for flexible installations in homes and light commercial spaces, this repeater hub ensures responsive local control even when your internet connection is unavailable. It also integrates seamlessly into a wider smart home ecosystem, supporting voice assistants like Amazon Alexa and Google Assistant, wearable controls such as Apple Watch, plus geofencing and scheduling for automated daily routines.

Whether you’re upgrading a traditional lighting setup or building a fully automated environment, the RRK-SEL-REP2-BL brings dependable connectivity and intelligent control to your lighting and shade automation projects.

How It Works Within the System

The RRK-SEL-REP2-BL acts as the central hub and repeater for the RA2 Select smart lighting ecosystem. It connects via an Ethernet cable to your home network, creating a reliable communications foundation for all linked wireless devices. Once installed, you use the Lutron App on iOS or Android to add, arrange, and customise devices, scenes, and automation schedules.

The repeater communicates over RF with paired devices (up to 100), linking dimmers, switches, Pico remotes, sensors, and blinds into a cohesive system. It also allows scene control, timeclock automation, geofencing triggers, and remote access worldwide. Even if internet connectivity drops, the hub continues to manage local functions — ensuring lights and shades respond to commands without interruption.

Your RA2 Select system can scale too — up to four additional wireless repeaters can be added to extend range in larger homes or complex layouts.

Our directions will be simplified, so make certain you watch each video in its entirety. Lutron RA2 Select System - System OverviewThe RA2 is a smart home system that can be wirelessly controlled by the free RA2 Select app. The system is managed via Pico controls - whether they be remote apps, pedestal mounted or wall fixtures. The Pico grants you control over features such as altering lights and blinds, in-line dimmer switches or audio systems. System integration allows for interaction with many other popular home systems including Nest, Google Home, and Alexa. We will explain each individual feature in more detail under the appropriate video.Buy the Lutron RA2 Select System Lutron RA2 Select Dimmer Install InstructionsWhen installing a Lutron RA2 Select dimmer, ensure the power is switched off for the area you are working in. Remove the light fitting in the setting to access the cabling. The live, neutral and earth wires will connect with their respective terminal in the dimmer. Next, repeat this process with the additional ‘load-out’ output cable to the dimmer. Install the strain relief, tighten the screws and finally screw in your end cap. Attach the output to the lamp you want to be dimmable - and as easily as that you have added a dimmable light to your Lutron RA2 system!
