The Matter Smart Home Standard Is Finally Available: Here's What It Means for Your Home

The connectivity protocol from Amazon, Apple, Google, Samsung, and others promises to make all your smart home devices work together

By Daniel Wroclawski

The way you shop for, set up, and use connected devices in your home is about to change with the arrival of the Matter smart home standard, which officially launched Nov. 3 at an event in Amsterdam attended by more than 30 companies that back the new connectivity protocol.

Brands big and small—including Amazon, Aqara, Brilliant, Eve, Nanoleaf, Philips Hue, Schneider Electric, and Tuya Smart—used the event to announce new products as well as software updates for products already in consumers’ homes so that they, too, will work with the standard. The goal of the Matter standard will enable individual connected products to work with the smart home system of your choice, be it Amazon Alexa, Google Home, or something else entirely.

“If it succeeds, this new standard will be a huge improvement and will allow consumers to choose models based on features and price rather than compatibility with a specific system, free from the worry that they may stop working due to inevitable changes in the industry,” says Bernie Deitrick, who has tested a variety of connected devices at Consumer Reports.

It was these compatibility issues that enticed Amazon, Apple, Google, Samsung, and other companies to create the new connectivity standard through the Connectivity Standards Alliance (CSA), a standards-setting organization for the Internet of Things industry. The effort began almost three years ago as Project Connected Home over IP (Project CHIP), and its supporting companies have grown from a few dozen to about 280.

The goal of the standard is to make all smart home devices interoperable. That means if you buy a product emblazoned with the Matter logo, you can use it with Amazon Alexa, Apple Home, Google Home, Samsung SmartThings, or any other ecosystem that meets the standard.

The first version of Matter was delayed a few times. The CSA says it now has 190 compatible products in the process of receiving certification, or are already certified, to support Matter. And throughout this past year, many companies—including Arlo, Belkin/Wemo, Comcast, Eve, GE Lighting, Ikea, and Yale—have announced plans to support the standard.

While the end goal of the Matter standard is simplicity, the questions raised now are pretty complex. That’s why we created this FAQ for consumers. We cover everything you need to know, including the benefits of the standard, the types of devices that will work with it, and privacy and security concerns. We’ll continue to update this FAQ with more information as it becomes available and the standard continues to roll out.

Why Does Matter, Ahem, Matter?

When you shop for a connected device—say, a smart TV, thermostat, or door lock—you’ll see a number of different labels on the packaging or in the website description: Works With Alexa, Works With Apple Home (formerly Apple HomeKit), Works With Google Home (formerly Hey Google, and before that, Google Assistant), and Works With SmartThings.

Each represents a different smart home ecosystem (Amazon Alexa, Apple Home, Google Home, and Samsung SmartThings, respectively) that you can use to connect these devices so that you can control them from a single app or smart speaker.

But this seemingly simple approach quickly becomes cumbersome as you build out your smart home. Some devices, such as the Schlage Encode smart lock, work with some systems (Alexa and Google Home) but not others. Not all ecosystems offer the same types of devices. For example, large appliances like washers and ovens are supported by Alexa, Google Home, and SmartThings but not Apple Home. And each subsequent device you purchase makes it more expensive and prohibitive if you decide to change ecosystems in the future.

All these problems go away if Matter succeeds in making interoperability a given for smart home devices.

What Are the Benefits of Matter?

The main goal of Matter is interoperability. All Matter-compliant devices will work together no matter which brand makes them. Matter promises three big benefits for consumers, says Michelle Mindala-Freeman, the CSA’s head of marketing: greater choice in the products and ecosystems they can use, a simplified user experience (in terms of setup, security, and more), and lower costs (because of greater efficiencies in engineering, manufacturing, and more by not having to support multiple “works with” programs).

“Matter makes it easier for a consumer to experiment and enter the smart home market,” Mindala-Freeman says. “So choice, simplicity, and cost are great for both current users and for new users.”

But the benefits don’t end there. Here are a few other ways that Matter will improve the smart home experience:

Local Control

Another big benefit is that controlling your devices will happen locally on your home network rather than over the internet, which involves each device manufacturer’s servers. That means interactions with your smart home devices, such as turning lights on or off, should happen much faster and keep working in the midst of an internet outage. And thanks to the local nature of the standard, Matter devices will continue to work even if their manufacturers go out of business or suddenly decide to shut down their servers, a problem that has plagued consumers who owned devices made by iHome, Insteon, Petnet, Revolv, Wink, and others in the past.

Matter Multi-Admin Control

Matter also allows you to control devices via multiple smart home systems at the same time through its Multi-Admin feature. That means you can turn on your lights from the SmartThings app on a Samsung smartphone, dim them by asking Alexa on an Amazon Echo speaker, and then turn them off from the Apple Home app on an iPad. According to a CSA spokesperson, there isn’t a hard limit to the number of different systems you can have running at the same time. But you won’t have to use one of the big four ecosystems if you don’t want to.

More Competition and More Choice for Consumers

Despite being backed by the most powerful tech companies in the world, the Matter standard will create more competition for the big four smart home systems (Amazon, Apple, Google, and Samsung). Any company can create an app and system that will be able to control all the same Matter devices that the big four systems can control. Ikea, for example, has announced that it will be updating its new Dirigera smart home hub to control all Matter devices in addition to Ikea’s own smart home products. And the startup Brilliant, which makes touchscreen smart home control panels, announced plans to update its control panels to control Matter devices.

Which Types of Smart Home Devices Will Work With Matter?

Right now, Matter will support lighting products (plugs, lightbulbs, switches, etc.), door locks, thermostats and HVAC controllers, blinds and shades, home security sensors (such as door and window sensors, motion sensors, etc.), and televisions and streaming video players.

Future iterations of Matter are expected to add support for security cameras, smart speakers, home appliances, robotic vacuums, smoke and carbon monoxide detectors, garage door controllers, wireless access points, environmental sensors, ambient motion/presence sensors, and energy management products (such as solar panels, electric vehicle chargers, and home battery packs). Some of these device types, such as garage door controllers and wireless access points, were initially announced as part of Matter 1.0, but they seem to have been pushed back to a subsequent standard update. That said, the CSA says it is committing to bi-annual updates for the standard that will include these new device types, as well as new features and improvements.

Notably, many smart speakers will work with the standard (see the next section), but only as Matter controllers (see the following section on smart home hubs), not as speakers. That means you can use them to control Matter devices either by the speakers’ digital assistant or smartphone app, but they themselves can’t be controlled by other Matter devices. It’s a confusing but crucial distinction.

Will Your Existing Smart Home Devices Work With Matter?

It depends. In its current form, Matter supports devices that connect to the internet via WiFi, Ethernet, and a new low-power wireless network called Thread. (The standard also supports Bluetooth, but only for the initial setup of a device.)

If an existing device uses one of those connectivity methods and has enough memory and processing power to support Matter, it could support the standard via a software update. If that’s not the case, the manufacturer could create a bridge (or update an existing one) to support Matter.

For example, Signify (maker of Philips-branded lighting products) has announced that it’s updating the bridge for its Philips Hue smart lightbulbs to support Matter, while Ikea has released its new Dirigera smart home hub to eventually bridge its smart home devices into Matter. But Belkin (maker of Wemo smart home devices) announced that it would be releasing new versions of its smart plug, smart light switch, and smart dimmer switch to support Matter over Thread. Existing Wemo products won’t be upgraded to support Matter.

Existing Devices That Currently Support Matter

As of the last update to this story, the following devices currently support Matter: all Apple devices running iOS 16.1, iPad OS 16.1, HomePod OS 16.1, tvOS 16.1, and watchOS 9.1; and all Aeotec and Samsung SmartThings Hubs (V2 and newer). We’ll update this list as we learn more.

Existing Devices That Will Be Updated to Support Matter

As of the last update to this story, the following devices will be updated to support Matter at some point in the future: all Amazon Echo and Echo Show smart speakers and displays except the first-gen Echo, first-gen Echo Dot, and Echo Tap speakers; the Aqara Hub M2, which will bridge Aqara ZigBee devices into Matter; Brilliant smart home control panels; all Eero Beacon, Eero Pro, Eero Pro 6, and Eero 6 mesh WiFi routers; all Eve devices with Thread, starting with Eve’s smart plug, motion sensor, and door/window sensor; all Google Nest smart speakers and displays; Google Nest WiFi and WiFi Pro routers; Google Nest Thermostat; the new Ikea Dirigera smart home hub; Philips Hue smart lights; Schneider Electric Wiser gateways and smart plugs; and Yale Assure and Assure 2 smart locks (via a new plug-in module). We’ll update this list as we learn more.

Will You Need a Smart Home Hub?

Yes, but it doesn’t need to be a stand-alone hub like in the earlier days of the smart home. Matter hubs—or controllers, as they’re called—can be built into other devices, or even simply be a smartphone app (such as the LG ThinQ app). For example, Amazon Echo, Apple HomePod, and Google Nest smart speakers will be able to act as Matter controllers. But why stop there? Samsung is building its SmartThings hub software into select 2022 Samsung Smart TVs, Smart Monitors, and Family Hub refrigerators, allowing them to control Matter smart home devices as well. The main advantage of hardware-based Matter controllers over software-based controller apps is that they allow you to control your smart home when you’re away from home (after all, you can’t take your phone with you and leave the app at home!).

What the Heck Is Thread?

Thread doesn’t have the name recognition of WiFi or Bluetooth, but the relatively new wireless network is likely to play a big role in the future of the smart home. It’s a low-power wireless mesh network. That means it’s very energy-efficient (helping to preserve the battery life of devices) and creates a network where smart home devices can relay information back and forth to other devices on the network. This extends the reach of the network and keeps it working even if a device goes offline.

Thread devices connect to the rest of your home network (and subsequently, the internet) through what’s called a Thread Border Router, a device that acts as a bridge between the Thread network and your home WiFi network. Unlike other bridges and hubs, though, Thread Border Routers can be built into other devices. The following products will—or are likely to—act as Matter-compatible Thread Border Routers: Amazon Echo (fourth generation) smart speakers; Apple HomePod Mini smart speakers; Apple TV 4K (2021) and Apple TV 4K (2022) WiFi + Ethernet streaming devices; all Eero Beacon, Eero Pro, Eero Pro 6, and Eero 6 mesh WiFi routers; Google Nest Hub Max and Google Nest Hub (second generation) smart displays; Google Nest WiFi and WiFi Pro routers; and the new Ikea Dirigera smart home hub.

Which Companies Are Supporting Matter?

There are about 280 companies currently in the Matter Working Group of the Connectivity Standards Alliance. We won’t list them all here (for that, go to the Matter website), but we’ll highlight some of the more notable members. In addition to Amazon, Apple, Google, Samsung, and other companies we’ve mentioned, the group includes ADT, Assa Abloy (maker of August Home and Yale smart locks), Ecobee, Facebook, Haier (parent of GE Appliances), Hisense, Ikea, iRobot (maker of Roomba robotic vacuums), Kwikset, LG, Panasonic, Resideo (maker of Honeywell Home products), Roku, Schlage, SimpliSafe, Sonos, Spotify, Tesla, and Whirlpool.

How Will You Know Whether a Device Supports Matter?

For existing products that are updated to support Matter, you’ll probably receive a notice from the manufacturer via email or an in-app notification. New products you buy will feature the Matter logo on the packaging or in the online store listing.

When Can You Start Buying Matter Devices?

Technically, you can buy them now. As we mentioned above, Apple devices and Samsung SmartThings hubs are ready to connect to Matter devices, thanks to recent software updates. The standard was finalized on Oct. 4 and officially launched on Nov. 3, meaning manufacturers are actively working to certify their devices to the standard. Once that process is complete for a given product, the manufacturer can start selling it. For example, at the Nov. 3 launch event, Nanoleaf announced new Matter-compatible smart light bulbs and lightstrips, but they won’t start shipping until early 2023.

Will Matter Help Protect Your Digital Privacy and Security?

It will establish a good foundation for security, but how well it will protect your privacy is still a bit unclear. The Matter standard uses blockchain technology, the same tech behind cryptocurrencies such as bitcoin, to verify that devices are legitimate and not potential bad actors. The standard also requires that all data being transmitted between devices be encrypted.

“Unless it’s secure, it’s difficult to say that you can exert privacy controls either by the consumer or by the manufacturer in an appropriate method,” says Tobin Richardson, the CSA’s CEO and president. “So our focus mainly right now on the privacy side is to make sure that it is as secure as possible.”

For now, you should consider the privacy protections of the ecosystem(s) you choose to use to control your Matter devices. Amazon and Google, for example, have faced criticism for logging the state changes (turning a light on or off, setting the thermostat temperature, etc.) of every smart home device connected to the Amazon Alexa and Google Home systems, even when you don’t control them from Amazon and Google devices. But Apple Home is designed in such a way that device data can be accessed only from your personal Apple devices, even when stored on Apple iCloud servers.

“We strongly support the idea of interoperability, but in order for consumers to trust it, privacy values really need to be incorporated,” says Justin Brookman, director of technology policy at Consumer Reports. “It’s great if different devices can talk to each other, but if there aren’t limitations on what all those companies can do with your personal data, interoperability actually introduces a lot more privacy challenges.”

Brookman compares it to what happened with Facebook and Cambridge Analytica several years ago. “Facebook used to be a lot more open, letting third-party apps collect and use all sorts of data,” Brookman says. “But if there aren’t rules and enforcement in place, bad actors can get access to information they shouldn’t have.”

Why Was Matter Delayed?

The Matter standard was first announced as Project Connected Home over IP (Project CHIP) in December 2019, three months before the coronavirus pandemic began to sweep the globe. As a result, much of the standard had to be created remotely because the developers had to work from home (just like many of us). Its first true release date was planned for 2021, but in August 2021 it was delayed to the middle of 2022. Then in March 2022 it was delayed again to fall 2022, when it finally launched.

What was behind the delays? Aside from the pandemic, the first delay was prompted by continued work on the Matter software development kit, which companies will use to make their products work with the standard. The second delay was due to continued work to make the standard’s software code as stable as possible and to accommodate more development platforms, which are sets of software and hardware offered by various vendors that allow companies to build new smart home devices. In the end, this should allow more Matter-compatible devices to come to market faster.

What About Z-Wave and ZigBee?

Z-Wave and ZigBee are two somewhat older wireless networks used by certain smart home devices, such as smart locks, sensors, lighting products, and more. For example, the CR-tested Kwikset Obsidian 954OBNZW500 uses Z-Wave. Devices that use either network also require a Z-Wave or ZigBee hub to control them, such as the fourth-generation Amazon Echo, Ring Alarm system, or Samsung SmartThings hub.

Z-Wave and ZigBee devices can’t work with Matter directly, but they could be connected to a Matter system with a bridge. For example, the Philips Hue smart lights and Ikea smart home devices mentioned earlier use ZigBee, and both ZigBee hubs are being updated to bridge them into Matter. No Z-Wave bridges have been announced yet.

This map shows how WiFi and Thread devices will connect in a Matter network, as well as how Z-Wave devices could be bridged into the Matter network.
