Amazon’s Echo smart speaker was a game changer when it launched in 2015. Since then it has continued to lead the Internet of Things (IoT) hub market in spite of increased competition from Google. The entire family of Amazon Echo products can be found in homes, offices, businesses, and several internet-connected mobile devices that allow Alexa, its onboard digital assistant, to reach the web.

The Amazon Echo is designed for the smart home, but there’s no reason it can’t be used in a smart office as well. If you’ve been seeking a hub for an IoT-connected office, it’s well worth your time to investigate one of the many Amazon Echo products available to see if one is a good fit, and TechRepublic has all the information you need right here. This Amazon Echo cheat sheet will be updated periodically as new software is released and new hardware is developed.

What is Amazon Echo?

It’s hard to be on the internet nowadays and not have heard of the Amazon Echo. Amazon’s smart speaker and IoT hub has sold over 5 million units since its launch in 2015, making it the easy leader in the smart speaker market.

The Echo, Echo Plus, Echo Dot, Echo Dot with built-in clock, Echo Studio, Echo Glow, Echo Dot Kids’ Edition, Echo Flex, and Echo Show 10 are all internet-connected speakers that come with Amazon’s Alexa digital assistant. (The Echo Glow does not have a built-in microphone and requires an additional Echo unit to operate.)

Along with these home-based devices are three mobile Amazon Echo products that allow users to connect to Alexa while out of the house: The AirPod-competitor Echo Buds, Echo Frames smartglasses (they don’t have display features and are essentially just glasses with Alexa built in), and the Echo Loop ring.

Amazon has also announced the Alexa Smart Oven, a combination microwave, convection cooker, and an air fryer. The oven doesn’t have a smart speaker and requires an Echo device to operate its smart features.

Alexa can control IoT devices, purchase goods from Amazon, play music, and perform a variety of app-like tasks called Skills, which can be installed from inside the Alexa app or Amazon’s Alexa Skills page.

Newer Echo products can even turn a regular “dumb” speaker into an Alexa-powered device, bring Alexa to your car, or let you voice-control a microwave.

All of the various Echo devices can be woken with a voice command, which is set to “Alexa” by default. The devices feature limited control buttons for volume, mute, and wake, but the products truly shine when their far-field microphones and speech recognition are used to make requests from the next room.

Why does the Amazon Echo matter?

The smart speaker/IoT hub marketplace is currently caught in a dual platform war, as is often the case in technology. This time it’s Amazon vs. Google, and the latter has a lot of catching up to do.

If Amazon’s digital assistant supremacy–and by extension the Echo’s market lead–continues, it’s likely anyone getting into IoT will have to make a choice between two platforms: Amazon’s and Google’s.

Amazon’s two years of additional sales time has given it a huge edge on the number of available Skills and smart home partnerships: It greatly outpaces Google in both of those areas.

Who does the Amazon Echo affect?

If you’re curious about the Internet of Things, the Amazon Echo affects you. Smart homes and smart offices need a main device that operates the thermostat, turns on the lights, streams video to the TV, controls the washing machine… the possibilities are too numerous to name and keep growing all the time.

SEE: Special report: Harnessing IoT in the enterprise (free PDF) (TechRepublic)

The Amazon Echo isn’t just a smart home hub—it’s also a digital assistant designed to do a lot of the same things as Siri, Google Assistant, Cortana, and similar technology. It can set timers, add items to a shopping list, get movie reviews, book restaurant reservations, and do a lot of the stuff you used to have to find your smartphone for.

Whether you want an Amazon Echo to set the thermostat, lock the doors, shut the blinds, or just keep a shopping list, the device can do it both at home and on the go with its mobile offerings.

Amazon Echo units are hardware products, but they’re inseparable from Alexa, Amazon’s digital assistant. When you start using an Echo in the office or home, you’re getting Alexa along with it, and Amazon knows it. Amazon launched in 2017 Alexa for Business, which gives myriad tools to businesses that want to integrate Alexa, and Echo products, into the office.

In September 2020 Amazon announced Alexa for Residential, a new program that allows property owners to not only wire Echo-enabled smart home features right into rental properties, but also to build smart skills for rental houses and apartments that let tenants put service requests in with a simple voice command.

How has the Amazon Echo line changed since it launched?

The original Amazon Echo was released to the public in June 2015. The Dot joined it in March 2016, and the Tap came to market in September 2016.

New Skills and IoT partnerships are released fairly regularly, and large announcements can be expected at most major trade shows like CES, which Amazon Alexa dominated in 2017.

Amazon revamped the Echo line with a new version of the Echo in September 2017, along with these new products: The smart home-centered Echo Plus, the tiny Echo Spot (no longer available), and the Echo Connect, which allows you to connect Alexa to a telephone landline.” Echo Buttons were also released, which function like game show buzzers for playing Echo games.

In September 2018, Amazon made another round of changes to the Echo product line, introducing new versions of products including the Echo Dot and Echo Show, as well as releasing a number of new Alexa-powered items.

Along with updated versions of the Echo smart speakers covered in the tech specs section of this cheat sheet, Amazon released the following new Echo products.

  • Echo Input: The Echo Input is roughly the same diameter as an Echo Dot, but it lacks a speaker. Instead, it’s designed to be connected to any standard speaker to turn it into an Alexa-powered smart speaker.
  • Echo Sub: While not a standalone Echo unit, the Sub pairs with one or two Echoes to create a better sound system. It’s a six-inch down-firing subwoofer that sounds like it will pack a punch, and vastly improve listening quality if your Echo serves as a home stereo system.
  • Echo Link Amp: The Echo Link Amp is an amplifier. It has a coaxial, line, and optical in/out, support for a subwoofer, and other standard amp features.
  • Amazon Smart Plug: The Amazon Smart Plug is a tiny IoT-powered plug that sits between a wall outlet and an appliance. Echo units automatically detect them when they’re on the same Wi-Fi network, and lets you specify what the Smart Plug is powering. You can then turn that old-fashioned electronic into a smart product that responds to Alexa commands.
  • AmazonBasics Microwave: This Alexa-connected microwave will respond to voice commands when it’s on the same Wi-Fi network as an Echo. Toss popcorn in it, say “Alexa, microwave some popcorn,” and it will get it done without you having to push a single button.
  • Echo Wall Clock: The analog Echo Wall Clock connects to Echo units and really only does one thing, aside from telling the time: It uses a ring of LED lights to visually display timers you’ve set with Alexa. If your kitchen is across the house, or office, from your desk it can be a great way to be reminded of a timer you set, and it’s only $29 to boot.
  • Echo Auto: Ever wanted to ask Alexa something in the car only to realize it wasn’t there with you? The Echo Auto aims to eliminate that problem. The small dash-mounted device connects to a smartphone and piggybacks off its data connection to provide full Echo-like capabilities while on the road.

In 2019, Amazon again expanded the Echo line to add the following products:

  • Echo Studio: This new premium Echo model is designed to compete with high-end audio products like the Sonos One smart speaker.
  • Echo Flex: This small device plugs directly into an outlet to act as an Echo device, USB wall charger, and night light all in one.
  • Echo Frames: Amazon’s new smart glasses, these fashionable frames are less Google Glass and more a pair of glasses-mounted smart headphones.
  • Echo Buds: The Echo Buds are Amazon’s response to the success of Apple’s AirPods.
  • Echo Loop: This smart ring has a clickable button that can be used to call Alexa and make phone calls to one pre-programmed contact. It also has a tiny speaker built in that you can hear by putting the ring close to your ear.

In 2020, Amazon updated the Echo line by introducing a new design for the standard Echo, Echo Dot, and Echo Kids Edition, transforming it into a sphere instead of the cylindrical Echo or puck-like Dot. Amazon also launched a new version of the Echo Show, making it the company’s first motorized display that turns to face the user by using the AZ1 Neural Edge processor to look for human shapes.

Along with new Echo units, Amazon also released the following Echo-compatible products in September 2020:

  • Ring Car Cam with traffic stop mode
  • Ring Car Alarm
  • Ring Car Connect
  • Ring Always Home Cam, a flying autonomous drone camera that can fly on a pre-programmed route inside your home, or can respond to the scene of action on a motion detector.

Who are Amazon Echo’s competitors?

There are a number of third-party smart speakers that aren’t manufactured by Amazon but partner with them so that they can use Alexa. I’m not including them here since they aren’t direct competitors.

Amazon Echo’s main competitor is Google Home. The hardware specs for the Google Home are similar to the Echo, and functionality of the device is very similar as well. The newest version of the basic Echo is a bit cheaper, though: $99 vs. the Home’s $129.

The Dot can be purchased for $49.99, the same price as the Google Home Mini, and the Echo Plus is slightly more expensive than the Google Home at $149.

The biggest difference between the Echo and Google Home may be both product’s suitability for business use. Amazon might have an advantage when it comes to hardware integrations and market share, but Google’s ecosystem is much larger, offers a wider range of products suitable for business, and has more room to grow. It’s important to remember that Amazon is an online marketplace, and Echo will always serve that purpose.

Google, on the other hand, is in the information business, which may give it an edge as the battle for smart home and digital assistant supremacy continues.

It’s also worth mentioning the Apple HomePod, Apple’s Siri-powered entry into the smart speaker market. If your interest in smart speakers is primarily driven by their business applications, the HomePod may not be the best investment–while it does have some business uses, it is primarily designed for home use.

How can I start using Amazon Echo?

All of the Echo devices are available on Amazon and at major electronics retailers.

Once you purchase an Echo, it’s simple to get it going—just install the app, turn on the Echo, and follow the onscreen instructions. Connection errors are infrequent and, as long as you don’t move the Echo outside of Wi-Fi range, you shouldn’t need to deal with any problems.

The Echo Loop and Echo Frames are currently only available via invitation, and only to Amazon customers in the United States. Anyone can request an invite, but Amazon said only a limited number of devices are available and not all requests will be approved. Be sure to check the links to those products in this guide to see the latest availability status.
