Lutron Caseta Dimmer Switch Guide: Where Should a Beginner Start?

The Smart Hub. Caseta switches talk to a small box called the Lutron Smart Hub, which plugs into your internet router. The listings say the hub works without relying on Wi-Fi for the switch connection, which is why Caseta is known for fast, stable response. Without the hub, the smart features (app, voice, schedules) do not work, so every product here except the starter kit says “Smart Hub required”.

The Pico remote. A Pico is a small battery-powered wireless remote you can mount on a wall like a switch or keep on a nightstand. It lets you add a second switch location, for example at the top and bottom of the stairs, without running new wires. That setup is called “3-way” control.

No-neutral wiring. A neutral wire is an extra white wire many smart switches need. Older homes often do not have one in the switch box. Caseta dimmers marked “no neutral required” avoid that problem, while the Caseta on/off switch for fans does require one.

Lutron Caseta Smart Dimmer Switch

Best for: Adding a dimmer to an existing Caseta setup

Pros

• No neutral wire required
• Works with existing bulbs
• Pico remote compatible

Cons

• Smart Hub sold separately
• Wattage limits not in listing

The Lutron Caseta Smart Dimmer Switch is the original Caseta dimmer, the sleek push-button design that has been the core of the line. It requires no neutral wire and, according to the listing, installs in as little as 15 minutes. It works with your existing bulbs and can make several lights or fixtures on one circuit smart at once.

With the Smart Hub, it connects to Alexa, Apple HomeKit, Google Home, Ring, Sonos and more, and the Lutron app adds scenes, schedules, geofencing (lights react when your phone arrives home), Smart Away and timers. A Pico remote, not included, adds a wireless second switch, and the listing says you can create setups with up to 10 devices. The listing does not specify the maximum LED or incandescent wattage for this dimmer, so check the manual for your bulbs.

This suits someone who already owns a Caseta hub and wants to add another room. First-time buyers without a hub should look at the starter kit instead.

Lutron Caseta Diva Smart Dimmer Switch

Best for: Dark or modern decor schemes

Pros

• Black finish
• No neutral required
• Soft-glow light bar

Cons

• Wallplate sold separately
• Spec sheet looks inconsistent

Best for: A finished look in one box

Pros

• Claro wallplate included
• Paddle and slider with preset
• Smart Away lighting

Cons

• Hub sold separately
• Neutral needs not stated in title

Best for: Doing two rooms at once

Pros

• Two Diva dimmers in one box
• Paddle with slider and light bar
• No neutral required

Cons

• Hub and wallplates sold separately
• Not for low-voltage lighting

The Lutron Caseta Diva Smart Dimmer Switch two-pack gives you two Diva dimmers with wire label stickers. Diva is Lutron’s paddle-style dimmer: you press a large rocker to turn lights on and off and slide a small slider to set brightness, with a soft-glow light bar showing the level. A preset feature brings lights back to your favorite level.

It handles up to 150W of dimmable LED or 600W of incandescent or halogen bulbs, and it is not rated for low-voltage track or landscape lighting. It requires no neutral wire, according to the title. With the hub (model L-BDG2-WH, sold separately), you get app control, voice control, schedules and Smart Away, which randomly turns lights on and off while you are away. Wallplates are sold separately.

Pick this if you plan to upgrade two rooms, such as a living room and bedroom. For one room with a finished look, the version with a wallplate is simpler.

The Lutron Caseta Diva Smart Dimmer Switch with wallplate includes one Diva dimmer and one coordinating Claro wallplate, the cover plate that goes around the switch. That means one box gets you a complete, matching result.

It shares the Diva features of the two-pack: paddle and slider, soft-glow light bar, preset, up to 150W dimmable LED or 600W incandescent and halogen, and full smart control through the hub. It supports single-pole and 3-way setups with a Claro smart accessory switch. The title of this listing does not repeat the “no neutral” note found on the other Diva listings, so confirm the wiring needs before buying if your switch box lacks a neutral.

This is a neat gift for someone who wants one room upgraded properly. Anyone doing several rooms will get more from the two-pack.

The Lutron Caseta Diva Smart Dimmer Switch in black is the same Diva paddle dimmer in a dark finish, according to the description. It includes one dimmer, with the wallplate sold separately, and its title says no neutral is required.

The features match the other Diva models: slider with light bar, preset, 150W LED or 600W incandescent and halogen, and smart control with the hub. Some of its spec lines look inconsistent with the other Diva listings, for example a 50 milliamp current rating and “surface mount”, so rely on the feature list and product manual rather than those spec lines.

It suits a home with black fixtures or dark walls, where a white switch would stand out. If color is not important, the white two-pack covers more rooms.

The Lutron Caseta Smart Dimmer Starter Kit is where most beginners should start. It includes one original-style Caseta dimmer, a Pico remote, a mounting bracket for the Pico and the Caseta Smart Hub. Since the hub is the part every other Caseta device needs, this kit gets you going in one purchase.

The dimmer offers flicker-free dimming of up to 150W of dimmable LEDs down to low light levels. The hub adds the Lutron app with scenes, schedules, geofencing, Smart Away and timers, and connects with Alexa, Apple HomeKit, Google Home, Ring, Sonos and more. The description mentions automatic adjustment for spring and fall time changes. The Pico can control from up to 10 locations. The listing does not state the neutral wire requirement for this kit.

This is the best gift for someone new to smart homes. After it, adding single dimmers or Diva switches is easy. Our lutron caseta combo guide shows how kits and add-ons fit together.

The Lutron Caseta Smart Light Switch is not a dimmer. It is an on/off smart switch for lights and ceiling fans. That matters because you should never put a regular dimmer on a ceiling fan motor.

The feature list says it supports LED, CFL, incandescent and halogen bulbs up to 600W and ceiling fans up to 6A; the description mentions different figures (720W and 3.6A for general-purpose fans), so check the manual for your exact load. It requires a neutral wire. It offers Apple Home, Alexa and Google Assistant support, schedules based on sunrise and sunset, Smart Away and geofencing with the hub. A 3-way setup needs a Pico remote or a second Caseta switch.

Choose it for a ceiling fan, a porch light or bulbs that are not dimmable. For any light you want to dim, pick one of the dimmers above.
