Swapping to smart switches can make a lot of sense. For one thing, you can boost your entire home’s energy efficiency since lights can be operated remotely via an app on your smartphone. You can also cut down on security threats by enabling vacation mode, which turns lights on and off randomly to fool potential intruders.
Smart switches work by connecting to your home’s Wi-Fi network or secure Z-Wave or ZigBee hubs, which operate via radio signal. Some models are also Bluetooth enabled. Fortunately, the best smart switch for you may not require a hub or home assistant to function flawlessly.
Instead, just install and operate from your phone. Whatever features you choose, there is a smart switch out there for you. This guide has suggestions for any household—whether you’re a smart home pro or getting started with home automation.

Before You Buy a Smart Light Switch
You have a few different options for boosting your home’s IQ. Smart light switches are a good choice for folks who may not have a home automation system but want to get started.
Switches add the ease of voice control to your life and allow you to monitor your lighting when you’re away from home or in another room. You can use smart switches with a range of bulb types, from LED to incandescent. Switches also provide different brightness levels, including dimmable and motion-sensing options.
Smart bulbs, in contrast, are mostly a single style of bulb (A-shape with a standard screw-in base), offering a range of colors and voice-activated controls. Smart plugs are probably the most versatile of all smart home tech options, allowing you to plug in a range of devices, including lamps, and monitor power usage.
Whether you choose smart switches, bulbs, or plugs comes down to your needs, familiarity with the technology, and the installation requirements with which you’re comfortable. You will also have to decide whether to invest in a home automation hub or not.
What to Consider When Choosing the Best Smart Light Switch
While smart homes take a little research when you’re starting out, the end result is worth it. Fortunately, you don’t need to invest in an entire home system to get the benefits of smart switches. Just be sure to know what kind of network and wireless technology you’ll be using to operate them as well as their compatibility with the rest of your home’s lighting and electrical wiring.
Smart switches need some form of wireless technology to function. Each brand will state on the packaging whether their model uses Wi-Fi (typically 2.4G), Z-Wave, ZigBee, or Bluetooth to operate. Each has its strengths and drawbacks, depending on your needs and preferences.
Switches that connect to your home’s Wi-Fi network are the most straightforward to install, especially if you don’t have a smart hub device. With Wi-Fi, your switch can connect directly to your smartphone via an app that you can download for free. If you want the benefits of smart controls without investing in a smart hub or smart security system, go for WiFi-enabled switches.
Z-Wave and ZigBee are radio protocols that do require a hub to operate. They work especially well when you have an entire smart home setup already up and running. Both Z-Wave and ZigBee networks use less power than Wi-Fi and are also highly secure and encrypted. Either option is a good choice for integrating your lighting and security system into your smart home hub.
Bluetooth has the shortest range of wireless networks. On the plus side, it doesn’t require a smart hub to operate and has the lowest barriers to entry and installation, especially if you’re considering smart home technology for the first time.
Bluetooth connects each light switch to your phone through an app, allowing you to monitor and control your lights from anywhere around the house. However, you won’t be able to monitor or control your switches from the internet or longer distances.
Whatever smart tech is already part of your daily life should guide your choice of smart switches too. In general, if you have a smart home system you already use and trust, it’s best to buy other intelligent devices that are compatible with it. If, on the other hand, you are new to the smart home world, you’ll want to do some comparison shopping.
In addition to smart home compatibility, you will also want to make sure your smart switch is compatible with your lamps and light bulb types. The most common types of bulbs are LEDs, CFLs, halogen, fluorescent, and incandescent. Most smart switches will list what types of bulbs they are compatible with on the packaging. On the whole, they are highly versatile and can operate with many different bulbs.
Most smart switches can be easily installed too. In general, they are hardwired into your home’s electrical system, replacing your regular switches. The majority of smart switches require a neutral wire, which allows power to return to its original source. Neutral wires are almost always white in color.
If your home doesn’t have a neutral wire, you can have one installed, invest in smart bulbs instead, or find a brand of smart switch that doesn’t require a neutral wire for safe installation.
With smart switches, you get all the functionality you’d expect from a regular light switch and then some. Beyond single pole switches, which just turn lights on or off, you have the following features to choose from:
- Dimmable switches offer the greatest brightness options, including mood lighting. They can be programmed and controlled through your home hub or smartphone to change levels depending on the seasons, time of day, or your travel schedule.
- Three-way switches allow you to operate a light from two different locations, such as at both ends of a staircase or hallway. In this case, you will need to replace your regular switches with smart switches at both locations.
- Motion-sensing switches are helpful for security outside your home as well as in rooms you frequent at night. Some smart switches are both dimmable and motion sensing, giving you tremendous flexibility and functionality overall.
