Why Apple, Amazon and Google Are Uniting on Smart-Home Tech
The new standard, arriving this year, provides a common language so all your devices can communicate with each other.
The new standard, arriving this year, provides a common language so all your devices can communicate with each other.
If you think about smart-home gadgets at all, you probably think about energy-saving thermostats or lights you control with an app. Most people don’t worry about how they work, let alone how they might work together.
Some of tech’s biggest players—Apple Inc., Alphabet Inc.’s Google, Amazon.com Inc. and Samsung Electronics Co.—have established smart-home platforms, so your iPhone can turn off the lights or Alexa can change the thermostat without too much extra setup. But that still means shoppers must check if new products work with the tech they already have at home.
Compatibility issues and setup complexity have made people slow to go all-in with smart-home technology. A new standard, called Matter, aims to change that.
When it rolls out this year, Matter will act as a common language spoken by most new—and many older—smart-home products. You could buy any gadget you wanted and connect it to whichever app you prefer. You’ll be able to control it with the voice assistant of your choice, or even use multiple assistants and apps inside your home.
Even though Matter would work behind the scenes, it could mean more affordable devices that are easier to set up and even play nicely together.
What’s perhaps most surprising: All the biggest names in smart-home tech are on board, so going forward, you won’t be trapped in one walled garden. If you get tired of Alexa and want to switch to Apple’s HomePod Mini, you could do it without having to also buy new automated blinds. (It’s a little like the film industry going all-in on VHS back in the day.)
“We all really recognized that unless we solved some foundational problems that were hitting all of us across the industry, this industry just wasn’t going to grow,” said Michele Turner, senior director of Google smart-home ecosystem.
Along with the tech giants, over 220 other companies support Matter. Between now and the end of the decade, vendors will ship more than 5.5 billion Matter-compliant smart-home devices, according to ABI Research.
Matter is designed to be more secure and private than other smart-home systems, in part because it can perform some basic functions without sending messages to the cloud. And you probably won’t have to throw out all your old smart devices.
That’s not to say the companies supporting Matter won’t try to lock you in somehow. Matter defines basic functionality, but advanced features will still be linked to companies—like how AirPods work better with Apple devices.
Initially, Matter will run in door locks; sensors for motion, air quality and more; thermostats; lighting; garage-door openers; blinds and shades; smart plugs; and smart TVs. More complex smart-home products, such as security cameras, robot vacuums and appliances, won’t be supported at launch.
When a developer wants to add a feature to its smart-home product, it has to expend resources to update the software for every platform. With Matter, most changes would only need to be made once, so developers could lower their prices.
Once you get your Matter-compatible product home, setup will be easy—you would just scan a QR code to add it to your network. “The goal is for the vast majority of devices out there—lights, plugs, switches, sensors—to make that initial setup so dead simple that it just takes a couple of seconds,” said Ms. Turner.
You can give your housemates smart-home access, letting them turn on the lights with Alexa while you use Siri. And if you have a mishmash of gear in your home, you might even get it all to work together. Right now, most people buy smart-home devices to address a “singular need,” said Adam Wright, an analyst with technology research firm International Data Corp., but that could change as more are compatible with Matter.
Google and Amazon’s home devices regularly communicate with the cloud, while Apple’s HomeKit is designed to work without as much internet dependence. Smart-home commands stay inside your home, which can make responses faster and more private. Matter takes a similar approach to HomeKit. If there’s an internet outage, your Matter-enabled products could still work, much like how your Wi-Fi printer still operates when your broadband is down.
“All smart-home accessories will have the same level of security, privacy and ease of use that Apple customers enjoy today with HomeKit accessories,” Apple spokeswoman Jacqueline Roy said.
In the past, Eve Systems GmbH didn’t link its smart plugs and sensors with Google and Amazon because they depend on the cloud, said Tim Both, Eve’s senior brand and product manager. Eve didn’t want to be responsible for user data. With Matter, the system’s data can stay inside your home, even if you use Google or Amazon’s platforms.
Amazon and others will still use the cloud for some things. Older Alexa-enabled smart speakers can’t process commands without it, said Chris DeCenzo, a principal engineer at Amazon working on smart home and Alexa devices, adding that the cloud is “a critical component of infrastructure for many, many smart-home devices and services today.”
If you already bought into the smart-home life, you won’t have to start over. Not completely, anyway.
All Philips Hue lights will work with Matter when the Hue bridges that control them get updated software, said George Yianni, co-founder of the Philips Hue lighting business, who now runs its R&D for parent company Signify NV. “Even ones we sold 10 years ago will become Matter-compatible.”
Most newer products from the giants will work with the new standard. Google’s Nest Wifi and its recent Hub displays will become connection points for Matter, while all Nest displays and speakers will get updates to control Matter devices. The newest Nest Thermostat will be compatible as well.
Nearly all Amazon Echo devices will let you set up and control Matter, too. Apple’s HomePod Mini and second-generation Apple TV 4K will be able to act as Matter hubs, as will Samsung’s SmartThings Hub v3.
Products that can’t be updated will continue to work as before, just without the increased compatibility. Assa Abloy Group will upgrade some of its Yale locks, but it can’t update its August line. Matter wasn’t designed “in a way that we can reliably run it on a Wi-Fi lock that runs on batteries,” said Jason Williams, president of the company’s August and Yale smart-lock businesses. The batteries would drain quickly, creating a poor user experience.
Some Yale locks can be upgradable with a hardware module—so you don’t have to buy a new lock but you still might have to spend a bit extra. The company aims to make all future consumer locks work with Matter, Mr. Williams said.
Despite any initial shortcomings, Matter may be the key to smarter homes, even the homes of people without Ph.D.s in electrical engineering.
“We know we’re competing with a light switch,” said Samantha Fein, vice president of business development and marketing at Samsung’s SmartThings. “So if it’s not as easy as that, we’re not going to get anywhere.”
Consumers are going to gravitate toward applications powered by the buzzy new technology, analyst Michael Wolf predicts
Chris Dixon, a partner who led the charge, says he has a ‘very long-term horizon’
How far can an electric car really go on a full charge? What can you do to make it go farther? We answer these and other questions that EV buyers might ask.
Many people considering an electric vehicle are turned off by their prices or the paucity of public charging stations. But the biggest roadblock often is “range anxiety”—the fear of getting stuck on a desolate road with a dead battery.
All EVs carry window stickers stating how far they should go on a full charge. Yet these range estimates—overseen by the Environmental Protection Agency and touted in carmakers’ ads—can be wrong in either direction: either overstating or understating the distance that can be driven, sometimes by 25% or more.
How can that be? Below are questions and answers about how driving ranges are calculated, what factors affect the range, and things EV owners can do to go farther on a charge.
The distance, according to EPA testing, ranges from 516 miles for the 2023 Lucid Air Grand Touring with 19-inch wheels to 100 miles for the 2023 Mazda MX-30.
Most EVs are in the 200-to-300-mile range. While that is less than the distance that many gasoline-engine cars can go on a full tank, it makes them suitable for most people’s daily driving and medium-size trips. Yet it can complicate longer journeys, especially since public chargers can be far apart, occupied or out of service. Plus, it takes many times longer to charge an EV than to fill a tank with gas.
Testing by Car and Driver magazine found that few vehicles go as far as the EPA stickers say. On average, the distance was 12.5% shorter, according to the peer-reviewed study distributed by SAE International, formerly the Society of Automotive Engineers.
In some cases, the estimates were further off: The driving range of Teslas fell below their EPA estimate by 26% on average, the greatest shortfall of any EV brand the magazine tested. Separately, federal prosecutors have sought information about the driving range of Teslas, The Wall Street Journal reported. Tesla didn’t respond to a request for comment.
The study also said Ford’s F-150 Lightning pickup truck went 230 miles compared with the EPA’s 300-mile estimate, while the Chevrolet Bolt EV went 220 miles versus the EPA’s 259.
A GM spokesman said that “actual range may vary based on several factors, including things like temperature, terrain/road type, battery age, loading, use and maintenance.” Ford said in a statement that “the EPA [figure] is a standard. Real-world range is affected by many factors, including driving style, weather, temperature and if the battery has been preconditioned.”
Meanwhile, testing by the car-shopping site Edmunds found that most vehicles beat their EPA estimates. It said the Ford Lightning went 332 miles on a charge, while the Chevy Bolt went 265 miles.
Driving range depends largely on the mixture of highway and city roads used for testing. Unlike gasoline-powered cars, EVs are more efficient in stop-and-go driving because slowing down recharges their batteries through a process called regenerative braking. Conversely, traveling at a high speed can eat up a battery’s power faster, while many gas-engine cars meet or exceed their EPA highway miles-per-gallon figure.
Car and Driver uses only highway driving to see how far an EV will go at a steady 75 mph before running out of juice. Edmunds uses a mix of 60% city driving and 40% highway. The EPA test, performed on a treadmill, simulates a mixture of 55% highway driving and 45% city streets.
Edmunds believes the high proportion of city driving it uses is more representative of typical EV owners, says Jonathan Elfalan, Edmunds’s director of vehicle testing. “Most of the driving [in an EV] isn’t going to be road-tripping but driving around town,” he says.
Car and Driver, conversely, says its all-highway testing is deliberately more taxing than the EPA method. High-speed interstate driving “really isn’t covered by the EPA’s methodology,” says Dave VanderWerp, the magazine’s testing director. “Even for people driving modest highway commutes, we think they’d want to know that their car could get 20%-30% less range than stated on the window sticker.”
The agency declined to make a representative available to comment, but said in a statement: “Just like there are variations in EPA’s fuel-economy label [for gas-engine cars] and people’s actual experience on the road for a given make and model of cars/SUVs, BEV [battery electric vehicle] range can exceed or fall short of the label value.”
Pick the one based on the testing method that you think matches how you generally will drive, highway versus city. When shopping for a car, be sure to compare apples to apples—don’t, for instance, compare the EPA range estimate for one vehicle with the Edmunds one for another. And view all these figures with skepticism. The estimates are just that.
Batteries are heavy and are the most expensive component in an EV, making up some 30% of the overall vehicle cost. Adding more could cut into a vehicle’s profit margin while the added weight means yet more battery power would be used to move the car.
But battery costs have declined over the past 10 years and are expected to continue to fall, while new battery technologies likely will increase their storage capacity. Already, some of the newest EV models can store more power at similar sticker prices to older ones.
The easiest thing is to slow down. High speeds eat up battery life faster. Traveling at 80 miles an hour instead of 65 can cut the driving range by 17%, according to testing by Geotab, a Canadian transportation-data company. And though a primal appeal of EVs is their zippy takeoff, hard acceleration depletes a battery much quicker than gentle acceleration.
It does, and sometimes by a great amount. The batteries are used to heat the car’s interior—there is no engine creating heat as a byproduct as in a gasoline car. And many EVs also use electricity to heat the batteries themselves, since cold can deteriorate the chemical reaction that produces power.
Testing by Consumer Reports found that driving in 15- to-20-degrees Fahrenheit weather at 70 mph can reduce range by about 25% compared to similar-speed driving in 65 degrees.
A series of short cold-weather trips degraded the range even more. Consumer Reports drove two EVs 40 miles each in 20-degree air, then cooled them off before starting again on another 40-mile drive. The cold car interiors were warmed by the heater at the start of each of three such drives. The result: range dropped by about 50%.
Testing by Consumer Reports and others has found that using the AC has a much lower impact on battery range than cold weather, though that effect seems to increase in heat above 85 degrees.
“Precondition” your EV before driving off, says Alex Knizek, manager of automotive testing and insights at Consumer Reports. In other words, chill or heat it while it is still plugged in to a charger at home or work rather than using battery power on the road to do so. In the winter, turn on the seat heaters, which many EVs have, so you be comfortable even if you keep the cabin temperature lower. In the summer, try to park in the shade.
Going up hills takes more power, so yes, it drains the battery faster, though EVs have an advantage over gas vehicles in that braking on the downside of hills returns juice to the batteries with regenerative braking.
Tires play a role. Beefy all-terrain tires can eat up more electricity than standard ones, as can larger-diameter ones. And underinflated tires create more rolling resistance, and so help drain the batteries.
The meters are supposed to take into account your speed, outside temperature and other factors to keep you apprised in real time of how much farther you can travel. But EV owners and car-magazine testers complain that these “distance to empty” gauges can suddenly drop precipitously if you go from urban driving to a high-speed highway, or enter mountainous territory.
So be careful about overly relying on these gauges and take advantage of opportunities to top off your battery during a multihour trip. These stops could be as short as 10 or 15 minutes during a bathroom or coffee break, if you can find a high-powered DC charger.
Fully charge the car at home before departing. This sounds obvious but can be controversial, since many experts say that routinely charging past 80% of a battery’s capacity can shorten its life. But they also say that charging to 100% occasionally won’t do damage. Moreover, plan your charging stops in advance to ease the I-might-run-out panic.
Yes, an EV battery’s ability to fully charge will degrade with use and age, likely leading to shorter driving range. Living in a hot area also plays a role. The federal government requires an eight-year/100,000-mile warranty on EV batteries for serious failure, while some EV makers go further and cover degradation of charging capacity. Replacing a bad battery costs many thousands of dollars.
Your EV likely provides software on the navigation screen as well as a phone app that show charging stations. Google and Apple maps provide a similar service, as do apps and websites of charging-station networks.
But always have a backup stop in mind—you might arrive at a charging station and find that cars are lined up waiting or that some of the chargers are broken. Damaged or dysfunctional chargers have been a continuing issue for the industry.
Be sure to carry a portable charger with you—as a last resort you could plug it into any 120-volt outlet to get a dribble of juice.
