How to Install Lutron Diva Smart Dimmer

Overview

Lutron Lutron Diva Smart Dimmer setup takes under 15 minutes for most users — if you're stuck, the steps below target the specific points where installs stall.

This guide covers the installation of the Lutron Diva Smart Dimmer in-wall switch, including wiring to your existing light circuit, neutral wire configuration, and Lutron Smart Bridge pairing through the Lutron app. The Diva Smart Dimmer replaces your existing wall switch and works with dimmable LED and CFL bulbs without smart bulbs.

Why This Happens in Real Homes

Unlike the older Caseta dimmer, the Lutron Diva Smart Dimmer requires a neutral wire — so before installing, confirm your box has a neutral (bundled-together white wires). It's the modern paddle-style Caseta dimmer, still using Clear Connect RF and the Smart Bridge.

Cut power at the breaker, connect line, load, neutral, and ground per the diagram, and cap any 3-way companion (use a Pico as the wireless companion). Pair it in the Lutron app; if there's no neutral in the box, the Diva won't work — the neutral-free option is the original Caseta dimmer instead.

What's Included

• Which wires connect where
