Smart home gadgets let you do things such as turn your lights on using your smartphone, stream music to a speaker using Alexa, lock your doors remotely, clean your house, and much more. But smart home gadgets are about more than just convenience. These devices can also help you save on heating and energy costs, let you know if someone's trying to break in, or if there's some other emergency.
The number of smart home products—from Amazon to Xiaomi—is rapidly growing. We've tested dozens of smart home devices, from cameras to lightbulbs to thermostats to smart light switches—even robot vacuums —to find the best of each for building your new smart home. Here are some of our favorites.
Latest News & Updates (September 2019)
- Facebook announced three new smart home devices, growing it's Portal gadget family. They include a redesign of last year's Portal smart display model ($179), as well as a smaller version called the Portal Mini ($129). The traditional video-chat monitors are joined by a combined camera and microphone attachment for your television known as Portal TV ($149).
- The Google Nest Hub Max ($229) is now available. This Google Assistant-powered device has a 10-inch display, forward-facing tracking camera for video chats, and act as a smart home hub.
Now in its second generation, Amazon's flagship smart speaker delivers great sound in an attractive package for less than $100.
Size: 5.8 x 3.4 inches (dia) | Speakers: 2.5-inch woofer, 0.6-inch tweeter | Wireless: 802.11a/b/g/n Wi-Fi (2.4 & 5GHz), Bluetooth
The second-generation Echo is smaller and more attractive than the original. Plus, you can change its skins to match your decor. Inside, the new Echo does all the same things the original does: control smart home gadgets, connect to other smart home hubs, read you audiobooks, check the weather, and even let you purchase things online just by using your voice. And, as a speaker, it sounds pretty good, too.

Our favorite smart thermostat has Alexa built in, but its real power lies in its remote sensors.
Size: 4.3 x 4.3 x 1 inch | Wireless: 802.11 Wi-Fi (2.4 and 5GHz), Bluetooth | Works with: Alexa, Google Assistant, HomeKit, SmartThings, IFTTT
The Fifth-generation Ecobee smart thermostat has everything we liked about its predecessor, the Ecobee4, such as Alexa built in, a slick touchscreen interface and a remote sensor that helps ensure all the rooms of your house are getting heated or cooled properly. But the newest version has a better speaker so you can actually use it to play music, all of Alexa's features (including Drop-In and messaging), and Spotify integration. The remote sensor has a longer battery life and better range, too.

These lights work with just about every other smart home system out there.
Bulb type: A19 | Wireless: Zigbee | Works with: Alexa, Apple HomeKit, IFTTT, SmartThings, Google Home, Nest
Philips Hue White starter kit includes two bulbs and a hub to connect them to other smart home devices. While you can't change these bulbs' colors, you can adjust their brightness (up to 800 lumens), and add up to 50 to a single hub. Philips' bulbs also work with a wide range of smart home systems, including Alexa, Apple HomeKit, IFTTT, Google Home, and Nest.
Philips also has an app, Philips Hue Sync, which lets users synchronize their smart bulbs with multimedia content on their Mac or Windows PC. For example, you can set your lights to flash and change color in time with music, video and movies being played on your computer. Users can also modify the color schemes and themes to suit their tastes.

Excellent video quality and facial recognition make this our favorite video doorbell.
Video Resolution: 1600 x 1200 | Field of View: 160 degrees | Works with: Google Assistant | Size: 4.6 x 1.7 x 1 inch | Wired/Battery: wired | Starting Storage Fee: $50/year for 5 days video
Nest's device has the best video we've yet seen from a video doorbell cam; its microphone and speaker were excellent, too. Nest's camera can recognize faces, and even announce them when they come to your door. While it needs a hardwired connection, it continuously records video, so you'll never miss an event. You can also set up specific zones, so you'll only be notified when a person or object appears in that area of the frame. While you'll need to subscribe to the Nest Aware service (starting at $5/month) to get all of its features, they're worth it.

This smart plug is simple to use and works with all of the major smart assistants.
Size: 3.8 x 2.4 x 1.4 inches | Works With: Alexa, Google Assistant, HomeKit, IFTTT | Electrical rating: 120V~/15A/60Hz/1800W
Belkin's WeMo Mini smart plug is our favorite smart plug. It's wide, but thin enough so that you can fit two of them per outlet. While it doesn't have energy monitoring, the Mini does work with HomeKit, Alexa, Google Assistant. A simple on/off switch also lets you control any appliance connected to it, no smartphone needed. It even has a clever Away mode, which lends the appearance that you're home.

Not only does the Nest Protect detect smoke and carbon monoxide, but its sensors are designed to pick up both slow- and fast-burning fires.

Makes connecting and automating smart home devices very easy.
Size: 5.5 x 5.5 x 1.2 inches | Wireless: Zigbee, Z-Wave, Wi-Fi
If you have a wide variety of smart home gadgets, you'll need a central system to integrate and control them all. While it has its imperfections, we found the Samsung SmartThings hub to be the best of the lot. It works with a wide range of devices and now has Wi-Fi built in, so you don't need to plug it into your router; this makes it easier to place in your house for the best connection to all your smart home devices.

An easy interface makes this a low-stress garage door opener.
Works With: Nest, SmartThings, Xfinity Home, Apple HomeKit, Google Home, IFTTT | Wireless: 802.11 Wi-Fi
Searching or reaching for that elusive garage door opener remote while trying to navigate a dark suburban street, toppled garbage cans or your kids' toys – or your kids – often proves awkward and dangerous. Chamberlain's garage door opener lets you tap your device's screen to open or close your garage from anywhere. Soon, the company also plans to add geofencing capabilities so it can sense when you're near your driveway to automatically open and, when your car is safely ensconced inside, close your existing garage door. MyQ can control nearly every garage door opener from all the major brands manufactured after 1993.

Best Robot Vacuum
Cleaning Performance: 94% | Pet Hair Score (Out of 100): 88 | Avg. Cleaning Time (H:M:S): 1:01:57 | Loudness (Decibels): 59.2 | Bin Size: 625 ml | Smart Home Connectivity: Alexa, Google Assistant | Size: 12.8 x 12.5 x 3.4 inches | Weight: 5.1 pounds
It's not easy keeping a house clean, but the Shark Ion R85 can certainly help. In our tests, this vacuum proved excellent at picking up pet hair and other debris around our home with a minimum of fuss. We also like its notifications, smartphone control and easy-to-clean dustbin.

Amazon Alexa vs. Google Home vs. Apple HomeKit: What should you get?
If you're looking to control your smart home devices by voice command, you have three main choices: Amazon Alexa, Google Assistant/Home, and Apple HomeKit/Siri. (Yes, there's also Microsoft Cortana, but it lags so far behind the other three, we don't recommend it for your smart home at this time.) We compared Alexa, Google Assistant, and Siri, both on their own and in conjunction with the best-sounding smart speaker with each of the assistants.
In short, Alexa generally came out on top, as it works with the most smart home devices, and has the most third-party skills. However, Google Assistant can do some things that Alexa can't—such as control Chromecast TVs—and it's rapidly being built into a number of third-party devices.
While you can control far fewer things using HomeKit, Apple tends to have stricter privacy controls and security measures when it comes to third-party smart home devices.
