The best smart home devices you can buy: Expert tested

The 3rd generation Amazon Echo Show is a great smart display and speaker combination for most smart home users, whether experienced or just getting started. Amazon's newest Echo Show 8 boasts a sleeker design with edge-to-edge glass, a centrally placed camera for video calls, and spatial audio from the smaller speaker enclosure.

I've been using the Echo Show 8 daily for almost a year, and this generation's improved processor delivers faster performance than older models. It's become my kitchen companion for running smart home routines, interacting with Alexa, and streaming music and video content on the 8-inch HD screen while cooking.

Review: Amazon Echo Show 8 (3rd gen)

This is the first Echo Show 8 to feature the camera in a central location rather than off to one side, which aids in better visual experiences during video calls. The camera also works for Visual ID personalization and Adaptive Content. Visual ID lets the Echo Show 8 recognize the household member approaching it to personalize content, while Adaptive Content adjusts the screen's content based on a person's proximity.

It's a highly rated smart speaker, with one buyer saying, "I purchased this a few months ago, and it has exceeded my expectations in every way. The Spatial Audio feature provides a rich and immersive sound experience, perfect for listening to music, podcasts, and even video calls. The smart home hub integration is seamless, allowing me to easily control all my smart devices. Alexa's responsiveness and sharp display make this device a pleasure to use daily. "

This starter kit has everything you need to make your lights smarter with Philips Hue. With two white and color smart bulbs and one Hue Bridge, you can begin switching out old light bulbs for new ones and later expand, as the Bridge can handle up to 50 Philips Hue lights. 

These Philips Hue smart lights are compatible with Alexa, HomeKit, and Google for voice control and integration. They're easy to set up using the Bridge, allowing users to control the lights wherever they use the app, set routines and automation, and expand their Philips Hue ecosystem with more products. 

Without a Hue Bridge, customers can only connect their lights to their mobile app via Bluetooth, so they can't change settings remotely.

Though not cheap, Philips Hue lights are some of the best in the market. One buyer said, "Love these smart bulbs and the ease to set up. Love that we can change the colors of the room from an app on the phone. Like how I can turn on lights when I need to when I'm away. Although I got the Hue bridge and two bulbs at a good price the cost of the color bulbs are expensive. "

The Nest Learning Thermostat has proven to be one of Google's best smart home products ever. With reliable performance and smart home integrations through Matter, this device has remained relevant for years, and the newest generation is no exception.

Switching from a dumb to a smart thermostat greatly impacted our home's climate control and energy efficiency. You can control your home's temperature from your phone, no matter where you are, and program it to enter Eco Mode when you leave the house. 

The new Nest Learning Thermostat looks gorgeous and looks like home decor. It can display the temperature, the outside weather, or a clock.  It also learns your patterns and trends and suggests new settings to help keep your home comfortable while saving you on utility bills.

"I'm upgrading from the learning thermostats that had the frosted glass look and had no trouble with installation, software setup just worked the first time," One buyer remarked. "The matter support worked without a hitch on HomeKit and Home Assistant. And it seems that it's doing a better job than my old one at keeping the rooms I care about comfortable. The master bedroom is always perfect now after a being in use for a week or so."

Don't you wish you could unlock your front door with your iPhone as easily as you can check out with Apple Pay?

The Aqara U100 is a smart lock that offers users the option to unlock by entering a predetermined passcode on the keypad, using their fingerprint, a physical key, a mobile app, NFC tags, or through Apple Home Key by simply holding their iPhone or Apple Watch up to their lock.

If you want to beef up your home security with a smart option, I can't recommend the EufyCam 3 and HomeBase 3 bundle enough. The three cameras are easy to install inside or outdoors, with a solar panel along the top that recharges the battery to use forever power. 

I've had the two camera systems set up outside my home for almost two years and have only had to recharge one of them, installed facing north, a handful of times -- that's how effective their solar panels are at keeping the batteries charged. 

Aside from the Eufy Security system being a great ecosystem for home security, expandable with many different camera types, it also offers users with more than one camera in their homes the ability to see the same event captured in a single clip by stitching different camera feeds together. 

"I wanted to be sure I had coverage on each side of my house (older neighborhood / long driveways). The setup was relatively easy, probably 30 minutes or less," one buyer commented. "I have them on 4k all the time and no issues with battery life, even on a string of cloudy or rainy days. The 4k is very clear -- even at night."

The cameras are wireless, so they can be installed almost anywhere. The HomeBase 3 is the local storage hub inside your home, where all the clips are saved.

EufyCam 3 and HomeBase 3 Features: Price: $530 | Power source: Solar-powered cameras, plug-in HomeBase | Resolution: 4K |  Compatibility: Google Assistant and Amazon Alexa
