Good lighting is the foundation of a secure and stylish home, and smart switches offer a whole new level of convenience.
Smart light switches are a way of configuring a home’s lighting to respond to verbal commands, program light timers, or notify users via smartphone alerts of problems in the lighting system. An upside is that while many of these switches are compatible with smart-home systems, plenty operate via Wi-Fi or Bluetooth.
How We Chose the Best Smart Switches
Curating our list of top picks involved researching the dozens of competing smart switches available on the market while paying close attention to aspects we considered most important to shoppers. We also got in touch with industry experts who lent us their hands-on experience with the technology side of smart devices and offered their advice on best installation practices.
We looking carefully at features being offered. “Look for power measurement to help improve energy efficiency. Look for electrical safety features like over-wattage, overcurrent, overvoltage, and undervoltage protection.” With this in mind, we ensured that our list only included reputable brands that deliver on safety features and several options.
Other top considerations we weighed were network connectivity, with most using Z-Wave or Wi-Fi, and control options. While new Z-Wave devices enter the marketplace daily, most homes are already set up with Wi-Fi. Z-Wave can indeed offer a more reliable signal, but at this time, Wi-Fi is more affordable, accessible, and convenient for most buyers.
When shoppers are considering smart switches, we selected switches that easily integrate with the most popular voice assistants (Amazon Alexa, Google Assistant, and Apple HomeKit) while offering remote control access via easy-to-use mobile apps.
Our Top Picks
Whether you’re looking for a simple switch that will detect motion and turn on the lights when you have an armload of groceries, or you’re looking for a way to save money with a switch that automatically turns off lights that are not in use, we’ve got you covered. The following list features a selection of the top smart switches available for smart lighting, all arranged by category.
GHome Smart Wi-Fi Light Switch
Product Specs
- Max load: 1,800W
- Type: Single pole
- Controls: Voice, mobile app, timer, touch
Pros
- No smart-home hub is required for the app to control the switch
- Includes an automatic on/off timer function
- Easily works with voice control devices like Amazon Alexa or Google Home
- Users can control their lights even when they’re not at home
Cons
- Some users have reported issues with app connectivity
Looking for the best smart switch for Alexa? The GHome smart light switch comes with Alexa preinstalled. Buyers will receive a set of four smart switches designed for use on a 1-way wiring setup, which means the switch is not a 2-way or 3-way switch—it controls only a single light, and no other switch controls the light.
The switch requires a neutral wire for installation. Once installed, it can be configured to work with Amazon Alexa or Google Home for voice commands, and no hub is necessary.
The corresponding app allows the user to turn the lights on and off, set a shutoff timer, or schedule a time for the lights to turn on. The GHome smart switch connects to a 2.4 gigahertz (GHz) Wi-Fi network, and buyers will receive step-by-step installation instructions.
Kasa Smart Wi-Fi Dimmer Light Switch
Product Specs
- Max load: 150-watt LED, 300-watt incandescent
- Type: Single pole
- Controls: Voice, mobile app, timer, touch
Pros
- Installation is easy and straightforward and the switches replace existing standard switches
- Integrates with the Kasa mobile app for controlling lights via smartphone
- Can be programmed to turn on or go off at preset hours
Cons
- Bulbs used in the light fixtures must be dimmable; noncompliant bulbs will not work
Get a boost on smart-home integration with budget-friendly smart switches from Kasa Smart. These switches are designed to replace standard single-pole switches—they come with a green wire (ground) and white neutral wire, plus a copper wire nut that attaches to the load wire and a black nut that connects to the hot black wire (use a wire tester).
Users can control the lights in various ways—manually. Just push the large button to turn the lights on and off, and then use the smaller buttons at the top to increase or decrease the light intensity. Controlling the lights from the Kasa Smart app is even easier.
Once the light is installed, the app wirelessly detects it and asks for a name, such as “kitchen” or “primary bedroom.” The lights can be turned on and off from the app and dimmed or preprogrammed to go on or off at set times. Kasa Smart switches are also compatible with Alexa, Hey Google, and SmartThings, so users have a variety of ways to implement these affordable switches.
Requirements for using the Kasa Smart switch are minimal: The home network should have a 2.4 GHz Wi-Fi connection, and the existing switch boxes should be at least 2 inches deep and have an existing neutral wire. In addition, the light bulbs used in the lights must be dimmable. Many of today’s bulbs are dimmable, but if using ones that aren’t, the lights may flicker or go off rather than dim.
What our tester says: Glenda Taylor, Bob Vila writer and product tester, had this to say about this Kasa Smart switch: “Installing the Kasa Smart switch was straightforward and user-friendly, and the Kasa app is excellent. I love how simple it is to navigate. Now, I can dim the lights in any room in my home—from my smartphone.”
