Lutron Caseta Smart Claro Accessory Switch for 3-Way - Expand Existing

In this review the Claro accessory switch is judged as a focused, practical addition for homes that already use a Lutron Diva smart dimmer or Claro smart switch. The single biggest reason to buy is simple: it lets you build reliable 3-way or multi-location lighting setups without a neutral wire and without replacing your existing primary dimmer. Installed in minutes and matching the Diva/Claro aesthetic, it is designed purely as an accessory so buyers should plan to pair it with the compatible base switch and, if they want voice or remote control, a Lutron smart hub.

Key Features

• Accessory-only design: Enables wired 3-way and multi-location control when paired with a Diva smart dimmer or Claro smart switch, avoiding the need to replace the primary device.
• No neutral required: Works with older and newer homes by not requiring a neutral wire, simplifying installation in many existing switch boxes.
• Multi-location expandability: Supports up to 10 accessory switches in a multi-location application so you can add control points across a room or hallway.
• Gesture control with Diva: When paired with a Diva dimmer, single tap restores a preset level, double tap reaches full brightness, and press-and-hold fades off slowly for flexible control.
• Smart hub compatibility: Add a Lutron Caseta smart hub to enable voice assistants, app control, schedules, and scenes while the accessory itself does not count toward hub device limits.
• Coordinated look: Matches the style and feel of Diva and Claro primary switches so additional locations keep a consistent finish and user experience.

Who It's For

The Claro accessory switch is best for homeowners who already own a Diva smart dimmer or Claro smart switch and want to add extra control locations without rewiring or replacing their primary device. Installers and DIYers who value a quick install and clear wiring instructions will appreciate that it requires no neutral and can be installed in under 15 minutes in many cases.

It is not for someone looking for a standalone switch or a primary dimmer replacement; this unit will not operate by itself and does not work with the original Caseta dimmer/switch models. If you need a single, independent smart switch or a dimmer that is compatible with the original Caseta devices, look at primary switches instead.

Pros & Cons

Cons
