Start with the Hub

Every device here is listed as Smart Hub required for app and voice control. A starter kit bundles the hub with dimmers and is usually the simplest first purchase.

Neutral Wire or Not

Older homes often lack a neutral in switch boxes. The Caseta Smart Dimmer, Diva and 3-way kit are listed as no neutral required; the on/off switches and ELV dimmer need one.

Match the Load Type

Use a dimmer for dimmable LED bulbs, the on/off switch for non-dimmable loads and fans, the fan control for ceiling fans and the ELV dimmer for ELV or MLV transformers.

Plan Pico Remotes for 3-Way

Caseta replaces a 3-way companion switch with a Pico on a wall bracket, so there is no new wiring. The Smart Dimmer listing says one Pico setup can control up to 10 devices.

Home Assistant and Range

Home Assistant’s Lutron Caseta integration uses the Smart Hub locally. Devices should sit within about 30 to 60 ft of the hub or a repeater, per the listings.

If you buy individual devices instead of a kit, start here. The Smart Hub connects to your router, runs the Lutron app setup and bridges Clear Connect devices to Alexa, Apple Home, Google Home and more. The listing stresses that Clear Connect does not interfere or compete with Wi-Fi devices. For makers, this is the box Home Assistant’s Lutron Caseta integration pairs with over your local network, so Pico presses and dimmer changes reach automations without the cloud.

The Diva brings Lutron’s familiar paddle-and-slider look to Caseta, so it blends in with existing Diva dimmers. Like the original, the listing says it does not require a neutral wire, needs the Smart Hub for smart features, and supports an easy 3-way setup with a Pico. Several colour and wallplate variants are sold under the same listing family, so pick the finish you want before checking out.

For loads that should not be dimmed, such as exhaust fans, non-dimmable LEDs or a ceiling fan on a single circuit, use the Smart Light Switch. Per the listing it requires a neutral, handles incandescent and halogen bulbs up to 600W and ceiling fans up to 6A, and works in single-pole or multi-location setups with Picos. It has 3,095 ratings at 4.7 stars.

The Claro Smart Switch uses Lutron’s popular Claro rocker design so a smart switch looks like an ordinary decorator switch. The listing highlights it for exterior lights in 3-way setups, notes that a neutral wire is required and that the coordinating wallplate is sold separately. It is the best-rated device in this guide at 4.8 stars, though from a smaller pool of 206 ratings.

Three-way circuits (one light, two switches) are where many smart switches get awkward. This kit pairs a Caseta LED dimmer with a Pico remote and a wall-mounting bracket, so the Pico sits over the old companion switch box. The listing says no neutral is required and that it works with your existing bulbs, no smart bulbs needed. Add the Smart Hub for app and Home Assistant control.

No wiring at all: the Plug-In Lamp Dimmer sits between a wall outlet and a table or floor lamp and adds Caseta dimming. The listing rates it for up to 100W and LED bulbs, and it needs the Smart Hub. Pair it with a Pico on a tabletop pedestal for a bedside control that never needs a phone. A good option for renters who cannot change switches.

For string lights, landscape lighting or a fountain pump, the Smart Outdoor Plug is listed as weatherproof and works with up to 15A LED fixtures or 1/2 horsepower motors. The listing advises mounting it within 30 feet of the Caseta Smart Hub or another Caseta device, which matters outdoors because walls and siding cut range. Use a Home Assistant sunset trigger and your patio lights look after themselves.

The Smart Fan Control replaces pull chains with wall and app control and lets you choose from 4 fan speeds, per the listing. It pairs with the dedicated Fan Pico remote (sold separately) for wireless control, connects with Alexa, Apple Home and other platforms through the hub, and supports schedules that set a speed or run a scene. In Home Assistant it appears as a fan entity with speed steps, ideal for temperature-based automations.

The Pico is the secret weapon of Caseta. The listing says it controls Caseta dimmers and plug-in lamp dimmers, turning lights on and off and brightening or dimming them from anywhere in the room; the tabletop pedestal and wall plate are sold separately. Makers love it because, through the Smart Hub, every Pico button shows up in Home Assistant as a trigger, so a coin-cell remote can run any automation you like. It has 2,849 ratings at 4.8 stars.

This battery-powered occupancy sensor turns Caseta lights on when you enter and off when the room empties. The listing gives a 180° field of view, a built-in light sensor and long battery life, and notes it works with Caseta devices and Serena smart shades within 60 ft. Lutron also sells a manual-on vacancy version if you prefer lights that only turn off automatically. It averages 4.5 stars from 961 ratings.

Unlike Zigbee or Z-Wave, Caseta devices do not mesh with each other, so the hub’s reach is the system’s reach. The Smart Hub Repeater fixes that: per the listing it extends Caseta range up to 60 ft and plugs into an outlet within 60 ft of the hub using the included power adapter. Add one for a detached garage, a far bedroom or a basement.

Track lights, under-cabinet strips and older low-voltage fixtures often use transformers that a standard dimmer handles poorly. The ELV Smart Dimmer is built for them: the listing gives up to 500W of incandescent, halogen or ELV or 400W of MLV, a 10W minimum load, and states that a neutral wire is required. It also supports the Pico bracket method for 3-way locations. Check the pack option on the listing, as it is sold in more than one configuration.

First Two Rooms

Buy the Deluxe Smart Dimmer Starter Kit: hub plus two dimmers gets a living room and kitchen done in an afternoon.

Old House, No Neutrals

Use the Caseta Smart Dimmer, Diva dimmer or 3-way kit, all listed as no neutral required.

Home Assistant Scene Buttons

Add Pico remotes: every button becomes a local trigger through the Smart Hub, perfect for movie scenes or goodnight routines.

Renting or Lamps Only

Plug-in Lamp Dimmers plus Picos on pedestals give smart dimming with zero wiring changes.

Patio and Garden

The Smart Outdoor Plug runs string lights or a pump; add a Hub Repeater if the patio is far from the hub.

Closets, Laundry and Garage

Pair a Smart Light Switch or dimmer with the Occupancy Sensor for lights that switch themselves on and off.

Do I need the Lutron Smart Hub for Caseta?

For app control, schedules, voice assistants and Home Assistant, yes: every in-wall device here is listed as Smart Hub required. A Pico remote can be paired directly to a dimmer for simple local control, but you lose all the smart features until a hub is added. The starter kit is the cheapest way to get the hub.

Does Lutron Caseta work with Home Assistant?

Yes. Home Assistant includes a Lutron Caseta integration that pairs with the Smart Hub on your local network. Dimmers appear as lights, the fan control as a fan, the outdoor plug as a switch, and Pico buttons as device triggers you can use in any automation.

Can I install Caseta without a neutral wire?

The Caseta Smart Dimmer, Diva Smart Dimmer and the 3-way dimmer kit are listed as no neutral required, so they suit most older switch boxes. The Smart Light Switch, Claro switch and ELV dimmer are listed as neutral required. Always switch off the breaker before opening a box, and use an electrician if you are not confident with mains wiring.

Can an RTL-SDR or 433MHz bridge read Caseta signals?

Clear Connect sits in the same general sub-GHz region as hobby 433MHz devices, but it is a proprietary, two-way protocol and generic RF bridges cannot control Caseta. Use the Smart Hub for control. If you want to experiment with 433MHz sensors instead, see our RTL-SDR dongles guide and 433MHz RF bridges guide.

Caseta or a Matter or Wi-Fi dimmer?

Choose Caseta for the most reliable dimming, no-neutral options and the Pico remote ecosystem, at the cost of a proprietary hub. Choose Wi-Fi or Matter dimmers if you want no extra hub or a multi-brand network. Our Matter dimmable smart plugs guide and Shelly devices guide cover those alternatives.
