Powerful, yet compact smart speaker from Sonos, with Amazon Alexa built-in.
High quality, dynamic sound, or pair two systems together for stereo sound.What We Don't Like
Bluetooth audio streaming not available.
The Sonos One (Gen 2) is a powerful home smart speaker, with both Amazon Alexa and Google Assistant built-in. Setup is quick and easy, and the Sonos One fills your home with high-quality sound without taking up valuable shelf space. It's available in both black and white color palettes.
Alexa works perfectly with the Sonos, allowing you to play music, ask questions, or check the weather. If you happen to have two Sonos One devices, you can pair them together to create a home stereo system. Although we'd like to see Bluetooth audio streaming, this is overall one of the best third-party smart speakers for Amazon.The 6 Best Home Theater Systems of 2021
Best for Cars:Roav Viva USB Car ChargerBuy on AmazonWhat We Like
Effortlessly stream from your phone through your car's radio system via Bluetooth with this easy to use tool.
Make hands-free calls and charge your devices quickly while on the road.What We Don't Like
Only one USB port.
If your vehicle is older and not equipped with Bluetooth, a connection tool is a must for making hands-free calls and listening to music. One of the best we found is the Roar Viva USB Car Charger. Although the connection to your phone's music via the FM radio can often mean annoying background static, the Roar Viva does a fantastic job providing clear, uninterrupted music, although in busy metro areas, there is a chance of some interference.
The device also contains a USB charger and it works well for making hands-free calls for driving. It's a really useful device and one of the more affordable car chargers on the market and is the best way to enjoy your own tunes on a long road trip or to avoid the annoyances of radio ads.The 9 Best Car GPS Trackers of 2021
Best for Smart Homes:Philips Hue Smart Bulb Starter KitBuy on AmazonBuy on Best BuyBuy on WalmartWhat We Like
Easy-to-install, voice-activated smart home lights.
Use the Phillips Hue app to create custom lighting sequences and routines for your home.What We Don't Like
If you're looking to upgrade the lighting for your smart home, the Philips Hue Bulb Starter Kit is one of the best options for an all-round, easy to install, and intuitive home lighting system. Although the initial investment is high, the Philips Hue bulbs are lasting, offering light in a range of colors.
The system can be easily controlled by Alexa, or even Google Assistant or Apple Home Kit, and custom lighting routines can be designed to ensure your home lighting is exactly how you prefer at all times of the day and night. You can set timers, adjust settings and lights when you're out of town, and create timers to sync with other activities in the home, like TV viewing. Up to 50 light points can be controlled per hub, which should be more than enough to cover most homes.The 8 Best Smart Hubs of 2021
Best Camera:Wyze CamBuy on AmazonBuy on WalmartBuy on Home DepotWhat We Like
Home monitoring and security camera, a high quality product at a fantastic value price point.
Automatic recording and cloud storage for up to 14 days.
Night-vision capabilities.What We Don't Like
Recorded videos are limited to 12 seconds.
Home security can be an expensive endeavor, which makes the Wyze Cam that much more appealing. It's an effective and high-quality home security camera, offered at a fraction of the price of their competitors. This voice-controlled camera works well with Alexa and can be used to live stream on your mobile from wherever you are, in 1080p.
The Wyze can be mounted inside or outdoors. We are impressed by its features, including night vision for distances up to 30 feet, 8x digital zoom, and clear, high definition footage from a compact camera. While you can't tilt it, multiple cameras can be used together to create a fuller picture. Video clips can also be stored and saved to the cloud, although clips are limited to 12 seconds, and they're only saved for 14 days. Still, this is the best home camera available in this price bracket.

This smart home thermostat programs itself and adjusts accordingly, once it learns your preferences and routine.
Use Wi-Fi or Alexa to control the temperature, no matter where you are.What We Don't Like
Homes should have a "C wire” installed to ensure consistent battery charging of the system.
Google's Nest Learning Thermostat is an intuitive smart home thermostat that can learn your routine and automatically adjust temperatures accordingly. The sleek, futuristic design is available in a range of colors to suit any home decor, and its compatibility with any Amazon Echo device makes it a top choice for Alexa users.
After about a week of use, the system starts to recognize your patterns and can adjust the air and heating to match. It also works well to save energy whenever possible, indicated by a leaf system to show you've chosen an energy-efficient temperature. Once you get through the set-up and learning time, the result is a beautifully designed thermostat that works almost on autopilot, ensuring your home is heated just how you like.How to Set up Your New Google Nest Smart Thermostat

A simple but effective smart plug that works with the Alexa app to add smart home voice control to any home outlet.
Set up is simple and the Smart Plug can be used with any device with a mechanical on/off switch.What We Don't Like
The design falls a bit flat.
The Amazon Smart Plug is an easy way to extend the reach of Alexa throughout your home. This small, square plug fits into any outlet in your home and works with Alexa to control your smart home with your voice—turn off the lights and create an evening or morning routine. Even if you don't have a smart home hub, this can be done via the Alexa app.
There's an outlet in the plug that can be used to control any device with a mechanical on/off switch, such as a fan, lamp, or a kettle, allowing that device to be easily controlled by Alexa. Set up is quick and easy and we love the convenience it provides for simple tasks like remembering to turn off the lights or turn on a fan from across the room.The 10 Best Smart Plugs of 2021

The August Smart Lock allows you to lock or unlock your home remotely and works alongside your current lock, so the keys will still function.

Installation is simple, and the Smart Lock provides security and peace of mind for any property. Control the lock via Alexa or the August app to open the door for a few minutes to a few hours, and locking can be set to happen instantly or after a set duration.

In addition to streaming, the Fire TV Stick 4K has 8GB of storage for additional games or apps.
As an Amazon product, integration with Alexa works well for playing movies or exploring the channels, but note the voice control doesn't work for every app on the system.

Best Smart Doorbell:Ring Video Doorbell 3Buy on AmazonBuy on Best BuyBuy on Home Depot
The Ring Video Doorbell 3 is an excellent 1080p video doorbell that lets you easily and securely control access to your home from a distance. It's an upgrade to the Video Doorbell 2, adding improved motion detection, privacy zones, audio privacy, and dual-band Wi-Fi connectivity. Installation is simple since you have the option of using a rechargeable battery pack to connect the doorbell wireless or you can get an electrician to wire it up for you if it's your own home. Tools are included to mount the doorbell and it's easy to set up and program through the Ring app.
Among its features, the Doorbell 3 integrates with Alexa, letting you hear announcements on your various devices when the doorbell is pressed.

The best Amazon Alexa accessory will depend on your needs, but our top choice for music is the Sonos One (Gen 2) (view at Amazon) for its high-quality audio, compact design, and ability to create a stereo system by pairing multiple devices. For cars, we like the Anker Roav Viva USB Car Charger (view at Amazon). It allows for easy streaming from your phone to your car's radio system, and allows you to make hands-free calls and charge devices on the road.
What to Look for in Amazon Echo Accessories
Battery bases: Most Echo devices aren't mobile, but you can make both the Dot and the standard Echo mobile with a battery base. This is a great accessory if you want to take your Echo into the backyard and don't want to mess around with extension cords.
Stands and mounts: Echo devices are designed to work right out of the box, but the right stand or mount can make them even easier and more convenient to use. Look for a mount to attach your Echo Dot to a wall and get it up off the counter or an adjustable stand for your Echo Spot to make the screen easier to see.
Smart hubs: Unless you have an Echo Plus, you need a smart hub if you want to use your Echo to control smart devices like lights, switches, and thermostats. Look for a hub that's certified to work with Echo and Alexa, and you'll be well on your way to turning your house into a smart home.
