Neutral or No-Neutral

Most smart switches need a neutral wire (usually white) in the box. If yours has only line, load and ground, choose a no-neutral model like the SONOFF ZBMINIL2 or MINI Duo-L, or go wireless.

Replace, Hide or Stick On

In-wall switches replace the switch you see. Relay modules hide behind your existing switch, so the faceplate stays. Wireless switches stick to the wall and control smart bulbs with no wiring.

Dimming

On/off relays won’t dim. For dumb dimmable bulbs, use an in-wall dimmer like the Enbrighten. For smart bulbs, a wireless dimmer (Hue, Lutron Aurora) dims the bulbs directly.

3-Way & Multi-Gang

Hallways and stairs controlled from two places need 3-way support. Check whether a switch needs companion add-on switches, and look for double or triple gangs when one box controls several circuits.

Hub Ecosystem

Enbrighten pairs directly with Echo Zigbee hubs; SONOFF works with most Zigbee hubs and Home Assistant; Aqara needs an Aqara hub; Hue and Lutron Aurora are built for the Hue Bridge.

The ZBMINIL2 is the answer for older homes with no neutral wire. This tiny relay hides behind your existing switch, so you keep your faceplate and physical switch, while your hub gains on/off control and automations. SONOFF says it fits easily into standard wall boxes and works with Zigbee hubs even without internet. With more than 800 ratings at around 4.4 stars, it’s a proven choice. As with most no-neutral devices, very low-wattage LED loads can flicker, and it switches on and off rather than dimming.

If your box does have a neutral, the ZBMINIR2 is the more robust relay. It needs a neutral wire, which keeps it always powered so it works as a reliable Zigbee router and avoids the flicker issues of no-neutral designs. Wire your existing switch to its input and you keep normal wall control, including two-way staircase setups per SONOFF. It has nearly 1,500 ratings at around 4.6 stars.

The MINI Duo-L puts two relay channels in one no-neutral module, so a single box with a double switch (say, kitchen lights and cabinet lights) can be automated with one device. SONOFF rates it at 16 A total and says no neutral is required, ideal for older homes. It has more than 210 ratings averaging about 4.3 stars.

Aqara’s H1 Smart Wall Switch is a clean US-format rocker switch that replaces your existing switch and needs a neutral wire. It uses Zigbee 3.0 and, per its listing, requires an Aqara hub, where it joins Aqara scenes and bridges to Apple Home, Alexa and Google Home; it is also community-supported in Home Assistant. Ratings are strong (around 4.4 stars from about 80 reviews), but Amazon showed only a few units left when we checked.

The double-rocker H1 controls two circuits from one switch position, handy for a bathroom light and fan or a ceiling light and porch light. Like the single version it needs a neutral and an Aqara hub. It averages around 4.6 stars from about 70 ratings, but stock was nearly gone when we checked, so verify availability.

The Hue Tap Dial combines four scene buttons with a smooth rotary dial for dimming, all in a battery-powered switch you can stick to the wall or lift off and carry. Each button can recall a scene or control a different room, making it a powerful scene controller for Hue lights. It averages around 4.7 stars from more than 950 ratings and also works with Home Assistant via Zigbee, where every button and dial movement can drive any automation.

The Hue Smart Dimmer Switch is the classic wireless light switch: four buttons for on, brighter, dimmer and off (or scenes), on a magnetic wall plate that lets it double as a remote. It needs no wiring and, with more than 4,000 ratings averaging around 4.7 stars, it’s one of the most trusted Zigbee controls on Amazon. It’s cheaper than the Tap Dial but lacks the rotary dial.

The Hue Smart Button is the minimalist option: a single button that turns lights on and off with a tap and dims or brightens when you press and hold. Hue also lets it cycle through natural-light scenes throughout the day. It mounts anywhere with no wiring and has around 185 ratings averaging about 4.6 stars. It’s perfect for bedside tables, hallways and kids’ rooms.

SONOFF’s Fusion SNZB-01M packs four buttons that each support single, double, triple and long presses, giving you 16 scene triggers from one small wireless switch. SONOFF lists support for SmartThings (via the Aeotec hub) and Home Assistant ZHA, making it a cheap way to build “movie,” “dinner” and “all off” buttons for any brand of light. It has nearly 400 ratings averaging about 4 stars.

If you want a modern glass touch panel controlling three circuits, MOES’s Full Touch Zigbee switch lists Zigbee2MQTT support and needs a neutral wire. It’s a striking look for kitchens and living rooms. It’s a very new listing with only a couple of reviews, and touch switches feel different from rockers, so confirm it fits your box format and suits your household before committing.

Replacing a US wall switch with a neutral?

The Enbrighten Zigbee Dimmer, or Aqara H1 if you use an Aqara hub.

No neutral in the box?

SONOFF ZBMINIL2 for one circuit, MINI Duo-L for two.

Want to keep your existing switch?

Hide a ZBMINIR2 (neutral) or ZBMINIL2 (no neutral) behind it.

Using Hue smart bulbs?

Lutron Aurora over a toggle, or a Hue Tap Dial, Dimmer Switch or Smart Button.

Scenes in Home Assistant?

The SONOFF SNZB-01M gives 16 triggers; the Hue Tap Dial adds a dial.

Want a modern touch panel?

The MOES Full Touch 3-gang switch, for Zigbee2MQTT setups with a neutral.

How do I know if my switch box has a neutral wire?

With the breaker off, remove the switch plate and look inside the box. In most US homes, a neutral is a bundle of white wires joined with a wire nut at the back of the box, not connected to the switch itself. If you only see the wires on the switch plus a bare or green ground, you probably don’t have a neutral; choose a no-neutral relay or a wireless switch. When in doubt, ask an electrician.

Should I use a smart switch or smart bulbs?

Use a smart switch when a room has many ordinary bulbs on one circuit or when you want normal wall control for everyone. Use smart bulbs when you want color or tunable white, and pair them with a wireless switch like the Hue Tap Dial or Lutron Aurora so nobody cuts their power. Avoid putting smart bulbs on a smart relay that switches them off. See our best Zigbee smart bulbs guide.

Do Zigbee switches work with Alexa?

Yes. The Enbrighten dimmer pairs directly with Echo models that have a built-in Zigbee hub, and most SONOFF relays work the same way. Hue and Lutron Aurora connect through the Hue Bridge, which links to Alexa. Aqara switches connect through an Aqara hub. In every case, you can then use Alexa voice control and routines.

Why do my LED bulbs flicker with a no-neutral switch?

No-neutral devices power themselves by passing a tiny current through the bulb even when off. With low-wattage LEDs, that trickle can make them glow or flicker. Fixes include using higher-wattage or more bulbs on the circuit, choosing LEDs rated for no-neutral dimmers, or adding a bypass capacitor if the manufacturer offers one.

Zigbee or Z-Wave light switches?

There are more US-style in-wall switches on Z-Wave, from brands like Zooz, Jasco and Inovelli, while Zigbee leads on relays, wireless switches and Hue integration. If you need lots of paddle switches and dimmers, see our Z-Wave light switch guides; if you already run a Zigbee hub, the picks above keep everything on one network.
