The best smart dimmer switches of 2025

Looking for the easiest path to smart lighting? Screw a smart bulb into a socket. Done! If you’re looking for something with more elegance and sophistication, however, you should replace the switches in your walls. Besides, the most common drawback of relying on smart bulbs with conventional switches is that someone inevitably turns the switch off. Boom! Your expensive smart bulb is now a dumb bulb that can’t be controlled with voice commands or be included in any lighting automations you’ve set up.

If there’s a downside to converting to smart in-wall dimmers and switches, it’s installing them. Don’t worry, it’s an easy DIY project. Be aware, however, that most–but certainly not all–smart controls depend on the presence of a neutral wire in the box. The neutral wire will supply constant power to the device’s radio, even when the load it’s controlling is turned off. If you’re not comfortable dealing with high-voltage wiring, hire an electrician for the job.

Now, don’t think we’re besmirching smart bulbs. They have their place, too; if for no other reason than being able to change the color of the lighting in a room. I’ve lived with smart lighting in my home for more than 15 years, and I can’t imagine turning my lights on and off without the options of using a voice command, in response to motion, on schedules, or with a smartphone app. You won’t be disappointed in the results.

Best smart dimmer overall — Lutron Diva Smart Dimmer (and the Lutron Caséta ecosystem)

Pros

Part of the robust Lutron Caséta smart home ecosystem
Broadly compatible with other smart products and systems
Doesn’t depend on a neutral wire

Cons

You must have Lutron’s Caséta Smart Hub wired to your home network
Lutron’s uncertain stance on Matter

Why we like the Lutron Diva Smart Dimmer (and its Caséta ecosystem)

Lutron built its own smart home ecosystem based on its proprietary Clear Connect technology. By definition, proprietary standards far less open than standards like Matter, Wi-Fi, Zigbee, or Z-Wave; however, the Caséta Smart Hub you’ll need to connect Caseéta products to your home network supports Amazon Alexa, Apple HomeKit, Google Assistant, IFTTT, Samsung SmartThings, and Sonos speakers, and more. And all that is in addition to Lutron’s own lighting products, smart shades and smart blinds, ceiling-fan controllers, motion sensors, and other products. With that degree of compatibility, it’s difficult to imagine a complex smart home routine that couldn’t be accomplished.

Who should buy the Lutron Diva Smart Dimmer (and its Caséta ecosystem)

Anyone looking to incorporate lighting controls into a robust smart home network should consider the Lutron Diva Smart Dimmer and a Caséta Smart Hub. Lights can switch on when someone rings a doorbell or automatically turn off when you leave home. If you have a Sonos speaker, you can automatically play music when you return home. While Lutron’s technology is not Matter compatible today, Lutron is a member of the Connectivity Standards Alliance that is responsible for developing Matter, so it’s possible that Caséta could be Matter compatible one day. Given the broad compatibility the Caséta ecosystem already enjoys, that ultimately might not make a difference. Lutron’s original Caséta dimmer switch is an equally good product and costs slightly less, but it looks a bit busier.

Best budget-priced smart dimmer — Kasa Smart Wi-Fi Dimmer Switch, Motion-Activated (model ES20M)

Pros

Endlessly tweakable motion-sensing options
Wiring design makes for easy installation
Attractive design aesthetic

Cons

Requires a neutral wire
Kasa app needs to be modernized
Motion sensing range is a bit weak

Why we like the Kasa Smart Wi-Fi Dimmer Switch (model ES20M)

TP-Link’s Kasa Smart Wi-Fi dimmer switch is remarkably inexpensive, and its Wi-Fi support means that it doesn’t require a smart hub to work. Users have immense control over how its motion- and light-sensing features work, with full support for fade-in/out options, motion sensing, and ambient light detection.

Who should buy the Kasa Smart Wi-Fi Dimmer Switch (model ES20M)

The low price makes the Kasa Smart Wi-Fi Dimmer an attractive alternative, but buyers will need to have access to a neutral wire at the installation point. This dimmer will not work with Apple HomeKit or 3-way circuits, but if you don’t need either of those functions, the Kasa Smart Wi-Fi Dimmer is an absolute bargain. Don’t have a neutral wire in the box where you want to install a motion-activated dimmer? Consider the GE Cync Dimmer, below.
