Lutron Diva Smart Dimmer for Caseta Lighting - Works with Alexa

Our review of the Lutron Diva Smart Dimmer for Caseta lighting finds it best suited for homeowners who want precise, reliable dimming with broad smart home compatibility. The single biggest reason to buy is its mix of familiar paddle styling with a tactile slider and LED backlight, combined with the ability to connect to Alexa, Apple Home, Google Assistant and more via the Lutron Smart Hub. Installation is straightforward for standard single-pole or 3-way circuits without a neutral wire, making it a practical upgrade for many existing homes.

Key Features

• Broad compatibility: Works with Alexa, Apple Home, Google Assistant, Ring, Serena shades and Sonos when paired with the Lutron Smart Hub, providing the most connected Caseta option.
• No neutral required: Installs in older homes without a neutral wire, letting users upgrade to smart dimming without rewiring.
• Precise dimming: The soft-glow light bar and slider allow smooth, fine-grained adjustment and a preset to return lights to a preferred level.
• Wide bulb support: Controls up to 150W of dimmable LED or 600W incandescent/halogen, so one dimmer can manage multiple existing bulbs.
• Smart away and automation: Use the Lutron app with a Smart Hub to schedule lights, enable Smart Away to simulate occupancy, and include the switch in scenes and routines.
• Remote options: Pair with a Pico remote or use a Caseta 3-way setup to mount remote controls without new wiring, adding flexible control locations.

Who It's For

This dimmer is ideal for homeowners and renters who want a smart switch that looks like a traditional paddle but adds modern app and voice control. It is especially good for people with existing LED or incandescent fixtures who need a no-neutral solution and for those who value compatibility with multiple smart ecosystems via the Lutron Smart Hub.

It may not be the best pick for low-voltage track or landscape lighting since it is not rated for those applications, or for buyers who want built-in voice control without purchasing the separate Lutron Smart Hub.
