MOES Smart Dual Dimmer Switch for LED Lights, WiFi, Single Pole, White

MOES Smart Dual Dimmer Switch for LED Lights, WiFi, Single Pole, White

3.5 86 reviews · $34.99

Two dimmers in one gang sounds handy, but the listing caps LED loads at 75 W, about half what a normal smart dimmer handles.

Why we'd skip it

  • The listing's own note gives a maximum of 75 W of LED/CFL, so a few fixtures can overload it.
  • It can't run 3-way circuits, smart bulbs, or fans, per the listing.
  • 3.5 stars from 86 reviews.
  • Raw HTML tags (<p>) show up in the product bullets, which doesn't inspire confidence in the listing's care.
See the listing on Amazon (so you recognize it)

Buyer's guide

Will a smart dimmer work with my LED bulbs?

Only with bulbs marked dimmable, and even then some combinations flicker or buzz at low levels. Dimmers with an adjustable minimum brightness (sometimes called low-end trim) let you raise the bottom of the range until the flicker stops.

What's the wattage rating about?

Smart dimmers list a maximum load, often around 150 W of LED and 600 W of incandescent. Add up the bulbs on the circuit. If you're close to the limit, pick a higher-rated model or split the load.

Can I use a smart dimmer on a ceiling fan?

No. Dimmers are for lights. Fans need a fan speed control or an on/off switch rated for motors.

Do I need a neutral wire?

Most smart switches need one because the electronics stay powered when the light is off. Open the box and look for a bundle of white wires tied together at the back. If it's there, you have a neutral. Older homes, especially those built before the mid-1980s, often don't. If yours doesn't, pick a switch listed as no-neutral.

Will a smart switch work on a 3-way circuit?

Only if it says so. A 3-way circuit controls one light from two switches. Some smart switches handle that on their own and keep the existing switch at the other end. Others need a matching add-on or companion switch, and some only work on single-pole circuits.

Can I install it myself?

If you're comfortable replacing an ordinary switch, the job is similar: power off at the breaker, confirm it's dead with a tester, and match the wires. Check local code, and hire an electrician if the box is crowded, the wiring is aluminum, or you're not sure which wire is which.
