Smart light switches beat smart bulbs for shared homes

Smart bulbs are a popular first step into the smart home, but Engadget argues that smart switches are a better place to start if you share your home with other people. The reason is simple. When someone flips the wall switch out of habit, a smart bulb goes dark and stops responding. A smart switch does not have that problem.

The problem with smart bulbs

A smart bulb needs constant power to stay connected to your Wi-Fi. Flip the wall switch off and it disconnects. Automations stop, voice commands fail, and the bulb stays unresponsive until someone turns the switch back on. After a power outage, many smart bulbs also come back at full brightness, which is not ideal during a nighttime storm.

Bulbs also lean on an app, a smart speaker or both. That works fine if you live alone. It gets awkward with kids, aging parents, roommates and guests who just want to press a switch.

Why switches work better

A smart switch replaces the wall switch itself and stays wired into your home's electrical system. Anyone can use it the way they always have, with no app and nothing new to learn. It simply controls power to the light or fixture.

• One switch can run every bulb on a circuit, such as a hallway chandelier.
• Automations tend to run more reliably, since no one can cut power at the switch.
• Many models are rated for ceiling fans and other wired loads, not just lights.

What it costs

Smart bulbs can cost from $5 to $50 each, depending on brand and whether they change color. A six-light chandelier with smart bulbs means buying, pairing and eventually replacing six devices. A single smart switch for the same fixture can cost as little as $11 each when bought in a bundle.

What to check before buying

Many smart switches need a neutral wire, so check that your wiring and system are compatible first. Also match the switch's load rating to what it will control. Smart dimmer switches should not be used with fixtures that have smart bulbs.

You can combine the two. If a smart switch cuts power to a smart bulb, the bulb loses app and voice on and off control until power returns. When it is on, you can still change color or brightness.

Where bulbs still make sense

Engadget does not say to drop smart bulbs. Renters who cannot change wiring can use them, and a plugged-in living room lamp suits one well. The suggested setup is smart switches in shared rooms like kitchens, hallways, bathrooms and living rooms, with bulbs saved for spots where color effects are worth it.
