The Lutron Hub Ra2 Select Main Repeater is a compact communication hub from Lutron for Ra2 Select systems, designed to centralise control of lighting and motorised shades. The unit’s minimalist, low-profile form and high-gloss black finish make it discreet enough for home or project installations while remaining recognisably Lutron in intent.
Form follows function: the repeater is a small rectangular cuboid with rounded vertical corners and a flat base, finished in a reflective black plastic. A horizontal seam marks the join of two moulded sections and the underside has small rubber feet for stable placement. The clean, monochrome aesthetic is intended for discreet positioning on a shelf, equipment rack or in a services cupboard.
Built from durable plastics and acrylic-like materials, the housing contains clearly identified connection ports. The rear panel includes a standard Ethernet (RJ45) port for a hardwired link to the local network, a micro‑USB interface and a circular DC/input-marked port. Silver-toned icons beneath each port aid rapid identification during installation.
Functionally the repeater acts as the central communication point for an Ra2 Select installation, connecting wireless dimmers, switches, Pico controls and wireless shades to a home network. It supports up to 100 wireless devices and is programmed and controlled via the Lutron app for iOS and Android. Once connected to your router by Ethernet the repeater enables scene control, scheduling and remote monitoring, and it integrates with Amazon Alexa, Google Assistant and the Apple Watch for broader smart‑home workflows.
Installation requires a wired Ethernet connection and local power via the micro‑USB or DC input. The repeater is supplied complete to operate within Ra2 Select systems; confirm included accessories and exact mounting constraints at purchase. Lutron supplies a two‑year limited residential warranty for Ra2 Select products.
