Yes. If you truly don't have a neutral wire in the switch box, my first choice is Lutron Caséta. No-neutral switches are relatively limited, and Caséta is particularly well regarded for reliability and LED compatibility.
Lutron Caséta Diva Smart Dimmer — my top pick if you want a modern paddle-style switch. It works without a neutral and supports up to 150 W of LED lighting. It does require a Caséta Smart Hub.
Lutron Caséta original dimmer — excellent if you don't mind the button-style design. It also doesn't require a neutral and is especially good with LED bulbs.
GE Cync No-Neutral Switch/Dimmer — a less expensive alternative that can work without a neutral and doesn't require a hub.
Leviton DN15S — another genuine no-neutral option, but it requires Leviton's Wi-Fi Bridge.
Lutron Diva Smart Dimmer - $74.20 (BuyRite Electric)
Lutron Caséta Smart Switch - $64.95 (Best Buy)
GE Cync No-Neutral Dimmer - $59.99 (Best Buy)
Leviton Decora Smart No-Neutral Switch - $44.43 (The Home Depot)
One important distinction: don't assume every Caséta switch is no-neutral. Lutron specifically notes that Caséta devices with a white neutral wire require a neutral; you want a model explicitly designed for no-neutral installation.
If you tell me (1) dimmer or simple on/off, (2) Apple Home/Alexa/Google/Home Assistant, and (3) whether it's a single-pole or 3-way switch, I can narrow it down to the exact model I'd buy.
Yes. If your switch box truly has **no neutral wire**, there are good options. - **Aqara Smart Wall Switch — US No Neutral** - $44.99 (Aqara LLC) - **GE Cync Smart Dimmer — No Neutral** - $59.99 (Best Buy)
Yes. If your switch box truly has no neutral wire, there are good options.
The Lutron Caséta/Diva Smart Dimmer is the one I'd choose for most homes. It specifically works without a neutral, has excellent LED compatibility, and doesn't depend on Wi-Fi for the switch's communication. Lutron rates the Diva for up to 150 W of dimmable LED or 600 W incandescent/halogen.
The catch: Caséta requires a Lutron Smart Hub if you want app/voice-control features.
Aqara US No-Neutral switch — $44.99 in the current product results; a good choice if you're already using Aqara/Matter.
GE Cync no-neutral dimmer — Wi-Fi/Bluetooth and doesn't require a separate hub, making it attractive if you want a simpler setup.
Leviton DN15S — specifically designed for no-neutral installations, but it requires Leviton's Wi-Fi Bridge.
Important: Don't assume a white wire is neutral—older wiring can use white as a switched hot. Turn off the breaker and verify the wiring before installing; if you're not comfortable identifying line/load/ground, an electrician is the safest route.
If you tell me (1) whether it's a single-pole or 3-way switch, (2) whether you want dimming, and (3) Alexa, Google Home, Apple Home, or Home Assistant, I can narrow it down to the best specific model for you.

Lutron Caseta Wireless Dimmer Go to product viewer dialog for this item. is the gold-standard smart light switch that operates reliably without a neutral wire , making it ideal for older homes.
Requires no neutral wire, works with almost any bulb type (incandescent, LED), and is exceptionally stable. It does require the Lutron Smart Hub to connect with apps and voice assistants.
Uses Zigbee 3.0 protocol and connects through an Aqara Hub to offer broad compatibility with Apple HomeKit, Alexa, and Google Assistant.
A tiny micro-module that installs behind your existing traditional light switch, providing smart dimming capabilities without needing a neutral wire.[1]
If you tell me which voice assistant or smart home platform you use (like Apple HomeKit, Alexa, or Google Home) and whether you need a dimmer or a standard on/off switch , I can recommend the exact model for your setup.

If you live in an older home, finding out that your switch boxes only contain "live" and "load" wires (and no neutral) is a classic roadblock. Fortunately, several top-tier brands make switches and modules designed specifically to run without a neutral wire. [1][2][3]
The best options on the market depend on your preferred smart ecosystem and wiring style:
Widely considered the gold standard for reliability. Most Lutron Caséta standard smart dimmers do not require a neutral wire (though they do require a proprietary Lutron Smart Hub for app/voice integration). They are rock-solid, rarely drop offline, and handle LED load flickering very well.[1]
If you prefer a micro-module that tucks behind your existing physical wall switch rather than replacing the switch faceplate itself, this is a great budget-friendly pick. It operates on Zigbee 3.0 (great for Home Assistant or Alexa ecosystems via a hub) and requires no neutral wire, working with loads down to 3W.[1]
Aqara offers single and double-rocker physical wall switches that don't need a neutral wire. They integrate wonderfully with Apple Home, Alexa, and Google Assistant, though they do require an Aqara Zigbee Hub to connect. [1][2]
A clever battery-powered (no rewiring/no neutral) smart switch option that replaces your existing faceplate. It communicates via a Tapo Hub and lets you retain smart control without messing with line voltage directly inside the wall box.

To help narrow down the ideal switch for you, let me know:
Absolutely. If your switch box **doesn’t have a neutral wire**, there are good options. ### My top picks - **Lutron Diva Smart Dimmer** - $69.95 (The Home Depot)
Absolutely. If your switch box doesn’t have a neutral wire, there are good options.
1. Lutron Diva Smart Dimmer (Caséta) — my top pick
No neutral wire required
Excellent reliability
Works with Alexa, Google Home, Apple Home, and other smart-home systems through Caséta
Dims LED lights up to 150 W
Requires a Lutron Caséta hub for full smart-home/app functionality.
Around $70 for the switch.
Leviton Decora Smart No-Neutral Dimmer + Wi-Fi Bridge Kit - $59.98 (The Home Depot)
2. Leviton Decora Smart No-Neutral Dimmer
3. Leviton Decora Smart No-Neutral Switch
For most homes, I'd go with Lutron Caséta. It's particularly good for older wiring and no-neutral installations, and its reliability is excellent.
One important catch: not every no-neutral switch works with every type of light fixture/bulb. If you tell me (1) whether you want dimming or just on/off, (2) what kind of bulbs you have (LED/incandescent/etc.), and (3) whether this is a single-pole or 3-way switch, I can narrow it down to the exact switch you need.

Yes — there are several good **smart switches that work without a neutral wire**, which is especially useful in older homes. ### My top picks - **Lutron Diva Smart Dimmer** - $69.95 (Best Buy)

Lutron Diva Smart Dimmer - $69.95 (Best Buy)
Lutron Caseta Smart Dimmer - $64.95 (Best Buy)
Leviton Decora Smart No-Neutral Dimmer - $59.98 (The Home Depot)
GE Cync No-Neutral Dimmer - $59.99 (Target)
Best overall: Lutron Caséta / Diva Smart Dimmer — My first choice for a no-neutral installation. Lutron specifically states that the Diva Caséta dimmer doesn't require a neutral and supports up to 150 W of compatible dimmable LEDs. It also works well for 3-way setups using Pico remotes.
Best if you want a conventional paddle:
— same Caséta ecosystem, but with a more familiar Decora-style paddle.
— specifically designed for older homes without a neutral, but it requires Leviton's Wi-Fi Bridge.
— designed to work without a neutral and connects directly to Wi-Fi, although its LED compatibility can be more dependent on the particular bulbs/load.
One important distinction: if you want a simple on/off switch rather than a dimmer, the options are different. Also, some products advertised as "smart switches" require a neutral even though other models from the same brand don't.
If you tell me (1) whether you need dimming, (2) Alexa/Google/Apple Home/Matter, and (3) whether it's a single-pole or 3-way switch, I can narrow it down to the best exact model.

Top options for no-neutral smart switches span different ecosystems and setups:
Add to list A reliable, mainstream brand solution. It works via Wi-Fi, but requires a separate Leviton Wi-Fi Bridge for app and voice control (Alexa, Google, Siri). Great if you already like traditional rocker styling.[1]
Add to list A budget-friendly touch-glass panel option that supports wiring with or without a neutral wire and explicitly includes a free capacitor in the box. It connects directly via Smart Life/Tuya apps.[1][2]
Add to list If you prefer a smart module that hides behind your existing physical light switch rather than replacing the wall plate itself, this ultra-compact Zigbee 3.0 switch requires no neutral wire and integrates smoothly with platforms like Home Assistant.[1]
Add to list Offers direct-to-app control via Bluetooth and Wi-Fi without needing a separate hub, designed specifically for older wiring configurations.

Leviton Decora Smart No-Neutral Switch - $44.43 (The Home Depot)
Leviton No-Neutral Dimmer + Bridge Kit - $59.98 (The Home Depot)
Best overall: Lutron Caséta / Diva Smart Dimmer — works without a neutral and has an excellent reliability reputation. It does require a Caséta Smart Hub for smart-home connectivity.
Best if you want simple ON/OFF rather than dimming: Leviton DN15S — specifically designed for installations without a neutral, but it requires Leviton's MLWSB Wi-Fi Bridge. Leviton confirms this in its product documentation.
Best if you want dimming with Leviton: DN6HD — also designed for no-neutral installations and requires the same bridge.
Don't assume every switch from a brand works without a neutral. For example, many newer Leviton and TP-Link models require a neutral; you need the specific no-neutral model.
If you tell me (1) whether you want dimming or just on/off, (2) Alexa, Google Home, Apple Home, or Home Assistant, and (3) whether this is a single-pole or 3-way switch, I can narrow it down to the best exact model for you.
