The best Alexa-compatible devices can give your home some serious smarts. Amazon's smart assistant lets you use your voice or phone to control certain models of smart lights, locks, speakers, TVs, and more connected to the Alexa smart home platform.

The best smart displays and Alexa smartphone app makes it easy to command compatible devices with or without your voice. Touchscreens allow you to tap on individual device controls or create 'routines' to automate your gadgets. For example, you can have a motion sensor act as a trigger that turns on lights when you enter a specific room. Spending the time to cook up efficient automations such as these makes your home more intuitive to your needs and streamlines your day while also helping you reduce energy usage.

Once you know how to use Alexa to create routines, you can have the assistant automatically change the temperature on your thermostat when you leave or return home. Or maybe you just want to wind down before bed; you can use an Alexa-compatible device to turn off your lights and lock your doors as part of a nighttime routine. 

There are hundreds of smart home devices that work with Alexa, and advertise as such on Amazon. And while all claim to be the best, most don't hold water when put through their paces. We've done the testing for you to come up with this list of the best Alexa-compatible devices below.

Weight: 16.4 oz
Ports: HDMI out, HDMI input, USB input, Ethernet, power, IR extender

Reasons to buy

Reasons to avoid

No HDMI cable included

Amazon's Fire TV Cube is the best Alexa compatible device for streaming. In fact, its powerful new octa-core processor makes it one of the best streaming devices on the market. In our testing, that improved speed is as snappy as the Roku Ultra (2020) and Apple TV 4K (2021). But this streaming device is more about its voice commands, as it's also an Alexa speaker. Not only does it let you control a cable box (or a live TV service if you cut the cord), but it's also able to control your TV volume and inputs.

This model also offers an HDMI-in port for those of us juggling all the devices, and puts a USB-A port and Ethernet inside as well, so no adapters are necessary for webcam connections or more stable streaming. That said, don't expect Amazon's new Super Resolution Upscaling feature to remaster your content, as it's more about proving smaller upgrades to non-4K content.

Requires hub

There are a lot of smart lights that work with Alexa, but we think the best Alexa compatible devices in this category are the Philips Hue smart lights. That's because Philips has the widest range of bulb types, and the Hue app lets you do far more with those lights than ones from other companies.

Philips sells several different types of smart lights, but the company's basic Hue White Starter kit includes two bulbs as well as a small hub that links the lights to your Wi-Fi. From there, you can command Alexa to dim the lights, and the bulbs will respond. The bulbs in this kit don't change color, though; for that, you'll want the Philips Hue White and Color Ambiance A19 bulb starter kit. In fact, Philips makes a wide range of smart LEDs and light fixtures; check out our guide to Philips Hue lights to see what each does.

Not compatible with 5Ghz Wi-Fi

The Wemo WiFi Smart Plug is one of the best Alexa compatible devices under $30 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 ask Alexa 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.

Keypad sold separately

Ever lie awake at night trying to remember if you locked the front door? As one of the best Alexa compatible device, the August Wi-Fi Smart Lock can bring ease to your anxiety. Just ask Alexa if your door is locked, and it'll tell you — and you can lock or unlock it using your voice. 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.

Ecobee's 5th-generation smart thermostat makes our list of the best Alexa compatible devices because among other things, it has Alexa built in. So, if you want to interact with Amazon's assistant, but don't want to install a separate smart speaker, you can simply use this thermostat.

With the Ecobee 5th generation smart thermostat, you get all of Alexa's features, including calling, messaging, and Drop-In. The new Ecobee also has a much better speaker and Spotify support, so it's now ok—but not great—for playing tunes if you're looking for a device to provide some background music. Most importantly, the new Ecobee has redesigned remote sensors that have much better range and battery life.

Best smart air quality monitor

6. Amazon Smart Air Quality Monitor

The best Alexa compatible air quality monitor

Reasons to buy

+
Responsive sensor quickly picks up on pollutants
+
Easy to set up and monitor on phone and Echo Show smart displays
+
Triggers connected Alexa devices

While the smart thermostat above controls your climate, this smart air quality monitor helps you learn about it. The device's front-facing air intake continuously checks your air and scores your environment on a simple 100-point scale. The five areas it looks at are temperature, humidity, particulate matter (PM), Volatile organic compounds (VOCs), and Carbon monoxide.

This little cube does a lot with the information it gathers. For one it displays trends neatly on visual graphs and notifies you about air quality drops. However, its most useful ability is the way it talks to your existing Alexa devices. For example, it can turn on your air purifier if your score goes below a certain threshold. Or it can activate a smart plug for your existing fan or air conditioner when it gets too hot.

Screen Size: 65 Inches
Resolution: 3,840 x 2,160
HDR: Dolby Vision, HDR10, HLG
Refresh Rate: 120 Hz
Ports: 4 HDMI 2.1, 3 USB
Smart TV Software: webOS 22

Reasons to buy

+
Impeccable OLED display
+

Google Assistant and Amazon Alexa built in

The LG C3 OLED TV is the best Alexa compatible TV. Not only is it one of the best OLED TVs thanks to an impressive display panel, but a premium design, maximum versatility and great smart TV platform hit all the high marks, too.

What’s more, this C series lineup is LG’s largest in terms of size options — the configurations span from 42- to 83-inches, all of which sport full arrays of HDMI 2.1 ports. Most also feature LG’s evo OLED panel. Plus, with LG's Web OS smart platform, that gives you flexibility if you want this TV to be the center of your Alexa-enabled smart home.

We can’t say our test results for this LG C3 OLED TV review showed significant improvement, but to be fair, there wasn’t much room to improve. Instead, what makes this one of the best TVs of the year is that it offers fantastic picture quality for the price — exactly what you’d expect from LG’s best-selling OLED TV series.

An upgrade to one of the best soundbars with Alexa built-in available, the second-gen Sonos Beam brings a new CPU, tweaked profiles, more audio formats, and HDMI eArc support into the mix. The drivers have been re-tuned, resulting in a crisper central channel that emphasizes vocal clarity and dialog. Dolby Atmos and other home-theater sound formats grant you numerous ways to experience wide 3D sound in your living room. 

Other unique features like NFC for seamless setup, as well as TruePlay to curate sound to your space and optimal couch position, bring more value to this small speaker system. It also pairs perfectly with 55-inch (or smaller) HDTVs.

You should know that Sonos products don’t come cheap and the price tag on this beauty might be a bit steep for the average consumer. Those who can afford it will find this to be a welcome addition to their ecosystem of Sonos products.

SimpliSafe is one of the best DIY home security systems because it's a cinch to set up, has a ton of options when it comes to sensors and accessories—it even has its own smart lock—and offers optional professional monitoring for a reasonable price. But it's also one of the best Alexa compatible devices because you can use Amazon's assistant to arm your Simplisafe system as you walk out the door. 

Simplisafe Essentials costs around $200, and comes with a base station, a keypad, three door/window sensors, and a motion detector; you can purchase additional sensors if you so choose. Simplisafe's professional monitoring fees start at $15/month, but if you want features such as smart home connectivity with Alexa, August, and Google Assistant, the fee increases to $25 per month.

How to pick the best Alexa compatible devices for you

While nearly every smart home product works with Alexa, knowing which are the best can be tricky. Things you'll want to consider include the following:
Design: Is this a well-made product? In the case of a smart plug, for instance, is it slim enough so that it doesn't block your other outlet?
Functionality: What features does the smart home device have? If it's a smart light, does it have a Home/Away feature, and can you schedule it to turn on at sunset?
Price: Often, the cheapest smart home device is not the best. You may be tempted buy a cheaper gadget, but make sure it meets your needs before buying it.

How we test the best Alexa compatible smart home devices

When reviewing any smart home device, we look at a few things before assigning it a rating:

  • Ease of setup: How simple is the device to install? 
  • Features: What features does the device have relative to others in its price range? 
  • Performance: Does it actually work as advertised? Is its app easy to use, with a sensible layout?
  • Price: How expensive is it when compared to similar devices? While this isn't the most critical criteria, it is a factor in its final rating.

If you're loyal to a single smart assistant platform, here are the best Google Home compatible devices, best HomeKit devices, and best smart displays
