The best smart home devices you can buy today
The name says it all: This is an Echo Dot with a clever LED clock built in its face. However, this seemingly simple addition adds a ton of functionality to the Echo Dot, making an even better smart home companion. In fact, we wish more smart home companies took Amazon's cue and make minor —yet effective — enhancements to already excellent devices.
More than just the time, though, the Echo Dot with Clock's display can also show you the current temperature, song titles and answers to math equations. It functions as a timer, too. It has an ambient sensor that automatically adjusts the brightness of the display based on the lightning of its surrounding environment, as well as a built-in temperature sensor that can trigger Alexa routines. The Echo Dot with Clock costs $10 more than the Echo Dot, but based on our experience, we think it's a worthwhile upgrade for those who want to know the time without having to ask Alexa. Truly the only downgrade is that it doesn't have the 3.5mm audio out port found on the previous Amazon Echo Dot with Clock (4th Gen).

The well-designed Nest Cam (battery) has a simple shape and is one of the easiest home security cameras to install, thanks to its magnetic base. Its 1080p camera captures sharp images day and night, and its microphone and speaker made conversations a breeze. That's the main reason we consider it the top choice among all the best security cameras we've tested.
The Nest Cam (battery) also offers three hours of rolling video storage for free, as well as person, vehicle, and animal detection. If you sign up for a Nest Aware subscription (starting at $6/month), you also get familiar face detection as well as the ability to store up to a month's worth of video.

The fifth-generation Ecobee SmartThermostat 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 most up-to-date 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.
Its audio can’t compete with the Echo Dot or other Alexa speakers in terms of quality, but the Ecobee is clever means of equipping a room with Alexa without plugging in another smart speaker. Not only is the Ecobee one of the best smart home devices you can buy, it’s our leading choice of all the best smart thermostats, too.

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. In fact, there's all sorts of things you can do with Philips Hue bulbs, check out these 9 things you never knew you could do with smart lights.
Philips Hue lights also have 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. For $30 more, you can upgrade your starter kit to include 4 bulbs instead of 2.

There wasn't much to improve on in our August Smart Lock Pro review, but the company went ahead and tweaked its original to make it smaller and easier to use. As our new top pick among the best smart locks, the the August Wi-Fi Smart Lock is 45 percent more compact than its predecessor, so it looks less obvious on your door. It also has Wi-Fi built in, so you can skip the August Connect bridge for linking your lock to your home network.
Everything we enjoyed about the August Pro is still here: An easy installation process, features such as DoorSense (which lets you know if your door has been left open), and compatibility all the leading smart home systems, from Alexa to Google Assistant to Xfinity. And, the August Wi-Fi lets you keep the keys from your existing deadbolt.

The Nest Doorbell (battery) gets almost everything right, and that's why it's not just one of the best smart home devices but the best video doorbell we've reviewed. The video doorbell's 3:4 vertical aspect ratio means you can see more of your front door; it can work either wired or on battery power alone, and it has a lot of great features, such as the ability to recognize familiar faces, packages, animals, and vehicles.
Even better is that the camera also offers some of those features for free, as well as three hours of rolling video storage — things that used to require a subscription. If you want longer storage, you can still sign up for Nest Aware, which starts at $6/month. As such, it pairs nice with the Nest Cam.

The $25 Wemo WiFi Smart Plug is one of the best smart home devices and our top choice among the best smart plugs. It's more compact than competing options out there, even its predecessor the Wemo Mini. And while it doesn't have energy monitoring like some other smart plugs, the Wemo WiFi Smart Plug does work with all the major smart assistants.
This smart plug has a physical switch, so if you don’t want to use your voice or an app to turn your appliance on or off, you can click the switch on the Wemo. It also has a clever Away mode. which can make it seem like you’re home even when you’re not by turning a lamp on intermittently.

The Nest Protect is the top choice among the best smart smoke detectors. When it picks up on something in the air, it sounds an alarm and lets you know what room in your home triggered the alert. Plus an LED ring on the bottom of the alarm changes color in case of an emergency, giving you and the people you live with a visual cue.
What we like most about the Nest Protect is how well it integrates with some of the best smart home devices. When you use smart home routines, your smart smoke alarm can automatically turn on your lights, making it easier for you to get out of your house. However, these routines only work for those who have converted their Nest account to a Google Assistant account. It also does not natively work with Alexa.

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.
Because the SmartThings hub has both Zigbee and Z-Wave antennas, you can pair it with several of the best smart home devices. Using the companion app, you can arrange dozens of scenes and automations. It also has a comprehensive home monitoring component, which can send you an alarm, record video, turn on lights, play sounds, and unlock your doors in the event of an emergency.

If you're looking for the best smart garage door opener, look no further than the Chamberlain MyQ. It includes a sensor for your garage door as well as a hub that connects to your Wi-Fi network. When you send a command using your smartphone, it is relayed to the hub, which then goes to the sensor that activates your garage door. The MyQ app, available for Android and iOS devices, lets you check to see if your door is open, and then close — or open — it remotely.
MyQ will work with most brands of garage door openers made after 1993 that have standard safety sensors, according to Chamberlain. Currently, MyQ works with Nest, SmartThings and Xfinity Home smart home systems. The one thing it doesn't do, though, is work with Alexa.

The Roborock S4 Max is the best robot vacuum overall for its affordable price, good feature set, and ability to keep your floors clean. It picked up an average of 94 percent of kitty litter on carpet and hardwood floors, and did even better with Cheerios and dog hair. It was in a virtual tie with the Roomba S9+, which costs more than twice the S4 Max.
The S4 Max was fast to map our home, and it was a fairly simple matter to create rooms in the app and then direct the robot vacuum to clean individual areas. You can even set specific times to clean rooms. As an Amazon exclusive, the Roborock S4 Max can run out of stock periodically, but it's worth picking up when it's available.

How to choose the best smart home devices for you
Choosing the best smart home devices is different for every shopper. Most of the decision comes down which smart home platform you prefer - you’ll want to buy devices that are compatible with your voice assistant so you can create routines or control your gadgets hands-free.
You have three main choices: Amazon Alexa, Google Assistant/Home, and Apple HomeKit/Siri. To help you get started, we have guides on how to use Alexa and how to use Google Assistant, as well as an Alexa vs Google Assistant vs Siri face off.
Alexa generally comes 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 in conjunction with its Works With Nest program. HomeKit’s availability is also growing, and could be the right platform for you if you use Siri often on your iPhone or iPad.
How we test the best smart home devices
All of the best smart home devices above are top picks within respective categories. We compare and contrast each gadget to similar options, taking variables like price, ease-of-setup, voice assistant compatibility and appearance into account. For example, the third-generation Amazon Echo is our favorite smart speaker overall because it has the best sound for the value, and represents its category on this list. The same goes for the Nest Cam and fifth-generation Ecobee.
That said, there are a number of excellent options within each category that are not featured on this list. If you’re looking for more buying choices, we have individual pages that detail all the best smart lights, smart doorbells, smart security cameras and more we’d consider reliable purchases for your growing smart home.
Check each of them out for more in-depth testing information for every category of smart home devices you should consider for boosting your home’s IQ.
