Matter — the IOT connectivity standard with ambitions to fix the smart home and make all of our gadgets talk to each other — has hit version 1.2, adding support for nine new types of connected devices. Robot vacuums, refrigerators, washing machines, and dishwashers are coming to Matter, as are smoke and CO alarms, air quality sensors, air purifiers, room air conditioners, and fans. It’s a crucial moment for the success of the industry-backed coalition that counts 675 companies among its members. This is where it moves from the relatively small categories of door locks and light bulbs to the real moneymakers: large appliances.
The Connectivity Standards Alliance (CSA), the organization behind Matter, released the Matter 1.2 specification this week, a year after launching Matter 1.0, following through on its promise to release two updates a year. Now, appliance manufacturers can add support for Matter to their devices, and ecosystems such as Apple Home, Amazon Alexa, Google Home, and Samsung SmartThings can start supporting the new device types.
Yes, this means you should finally be able to control a robot vacuum in the Apple Home app — not to mention your wine fridge, dishwasher, and washing machine.

The initial feature set for the new device types includes basic function controls (start / stop, change mode) and notifications — such as the temperature of your fridge, the status of your laundry, or whether smoke is detected (see sidebar for more).
Robot vacuum support is robust — remote start and progress notifications, cleaning modes (dry vacuum, wet mopping), and alerts for brush status, error reporting, and charging status. But there’s no mapping, so you’ll still need to use your vacuum app if you want to tell the robot where to go.
Air purifiers and air quality sensors are also interesting additions. Currently, support across platforms for air purifiers is spotty, and products are expensive. Matter supports a wide range of air quality sensors (see sidebar) plus location for sensors, so individual sensors placed around a home can feed data to a device like an air purifier, HVAC system, or a connected oven hood.

Here are all the new device types and supported functions the CSA has announced as part of the Matter 1.2 spec. This is in addition to the currently supported device types: light bulbs and light switches, plugs and outlets, locks, thermostats, blinds and shades, safety and security sensors, media devices, and bridges.
Smart home platforms such as Apple Home, Google Home, and Amazon Alexa can add these Matter device types to their platforms so you can control any compatible devices directly.
Refrigerators: Functions include temperature control and monitoring, and the device type covers any refrigerator device, including deep freezers and wine and kimchi fridges.
Room air conditioners: Standalone room air conditioners with temperature and fan mode control.
Dishwashers: Functions include remote start and progress notifications, plus notifications for water supply and drain, temperature, and door lock errors.
Laundry washers: Progress notifications, such as cycle completion. The CSA says dryers will be supported in a future Matter release.
Robotic vacuums: Functions like remote start and progress notifications, support for features like cleaning modes (dry vacuum and wet mopping), and status details such as brush and charging status and error reporting.
Smoke and carbon monoxide alarms: Support for notifications, audio and visual alarm signaling, alerts about battery status, end-of-life notifications, and self-testing. Carbon monoxide alarms support concentration sensing.
Air quality sensors: Supported sensors can capture and report on PM1, PM 2.5, PM 10, CO2, NO2, VOC, CO, ozone, radon, and formaldehyde. Matter devices can also provide AQI information based on location.
Air purifiers: Can pair with an air quality sensor for sensing data and uses functionality from other device types like fans and thermostats. Monitoring of things like filters (HEPA and activated carbon filters) is also supported.
Fans: Movement controls like rock / oscillation and modes like “natural wind” and “sleep wind” will be supported, plus changing the airflow direction (forward and reverse) and step commands for airflow speed.
Most smart appliances already provide most functions Matter supports, but they’re siloed in each manufacturer’s app. With Matter, you should be able to connect them to your smart home platform of choice, unlocking intriguing automation options.
While it’s possible today to get your lights to flash when your laundry is done, turn a light red when your fridge’s temperature rises, or shut off the HVAC system if the smoke alarm goes off, it can be complicated to set up and often wholly unreliable. You need to download multiple apps, maybe buy a sensor or two, deal with laggy cloud integrations, and worry about whether your washer is even compatible with your smart home app in the first place. With Matter support, this type of simple command and control should be much easier to implement in any ecosystem.
The future potential is also interesting, bringing into play the ambient smart home many companies are pursuing, where devices can talk to each other to take action on our behalf without us really having to get involved.
Tobin Richardson, president and CEO of the CSA, gave this example: “With more aggregate data and more information, we can see more interaction between devices,” he says. “With an edge AI engine to take care of it, if an air quality sensor senses something, then your favorite voice assistant platform can kick off the robot vac, boost the air purifier, and maybe hold off on the laundry and the dishwasher to save energy while the other devices are working.”
With manufacturers like Whirlpool, Panasonic, LG, Haier (which owns GE Appliances), and more all part of Matter, the potential is there for a broad implementation across home appliances. In particular, backward compatibility. I, for one, am not planning on buying all new appliances.
David Bean of Whirlpool tells me it plans to implement Matter across all its connected products in its brands, which includes Whirlpool, KitchenAid, and Maytag. While, initially, the ability to get notifications from your appliance across your smart home will be useful, “for us, it’s all about the possible abilities that are going to exist once we get Matter out there,” he says. “How we work with automations and scenes and how we build upon those and take digital experiences in the home to the next level.”
However, he didn’t share a timeline for when Whirlpool will implement Matter in any of its products. And while it’s just fridges, dishwashers, and washers today, “we see Matter going across the whole kitchen and laundry space,” he says.

A benefit of Matter for manufacturers is being able to focus efforts on products and features and not having to build support for multiple protocols or ecosystems or even necessarily make an app. (If you’ve spent much time with the app for your dishwasher or coffee maker, you’ll know what a blessing that will be.) An appliance can work with one or multiple Matter ecosystems with just Matter connectivity built in.
It’s not a requirement of Matter to support every device type
Assuming, that is, that the smart home ecosystems support the new device types. It’s not a requirement of Matter to support every device type, and while most currently support most devices, not all support all functions.
We don’t know yet if or when Google Home, Amazon Alexa, Apple Home, and Samsung SmartThings will add support for everything Matter has announced with 1.2, but judging by the responses I got when I asked them, it’s not going to be anytime soon.
Amazon’s Chris DeCenzo tells me the company plans to add support “over time.” “We’re working with partners to support the new device types included in the Matter 1.2 spec while maintaining our high bar for the customer experience with Alexa,” he says. Taylor Lehman at Google Home says, “We’re working hard to add more support for Matter devices to our ecosystem … this will take time.” I also reached out to Samsung SmartThings and Apple but neither provided an answer.

Matter is a new smart home interoperability standard that provides a common language for connected devices to communicate locally in your home without relying on a cloud connection. It is designed to be secure and private, easy to set up, and widely compatible.
Developed by Apple, Amazon, Google, and Samsung, Matter is an open-sourced, IP-based connectivity software layer for smart home devices. It works over Wi-Fi, ethernet, and the low-power mesh networking protocol Thread and currently supports over 20 device types. These include lighting, plugs and switches, thermostats, locks, security and environment sensors, refrigerators, dishwashers, smoke alarms, air quality monitors, and more.
All of this means that if a smart home gadget you buy has the Matter logo, you can set it up and use it with any Matter-compatible ecosystem via a Matter controller. Additionally, you can control it with multiple controllers simultaneously, a feature called multi-admin. Once connected to an ecosystem, a device can work with any others in that ecosystem, regardless of whether it’s a Matter device.
Amazon Alexa, Google Home, Samsung SmartThings, and Apple Home are some of the major platforms that support Matter, and they have all updated their compatible smart speakers, hubs, and other devices to be Matter controllers.
However, Paulus Schoutsen of Home Assistant tells me he expects support to be added to his platform soon. “We’ve already started testing with the new 1.2 version and working with the community and Matter device manufacturers,” he says. He also added that each new device type Matter supports “can be the reason for a manufacturer to adopt Matter, resulting in another private option for our users.” While manufacturers and ecosystems can leverage the cloud for additional features and remote control, it’s not a requirement.
The launch of Matter 1.2 isn’t coming with a slew of device announcements. I reached out to several companies that are members of the CSA and make products in these categories to see if they were announcing any new integrations. iRobot (makers of Roomba robot vacuums) and Resideo (owners of First Alert smoke alarms) said they had nothing to share, and Dyson (vacuums and fans), Google Nest (Nest Protect smoke alarm), and Samsung didn’t respond before publication.
Even the ever-eager Eve, which has been at the forefront of Matter adoption, told me it had nothing to announce. All this means we’ll probably not get new devices until 2024. While it’s possible that over-the-air updates to existing gadgets could be implemented sooner, it’s not likely. Many of those updates promised with 1.0 took a long time to arrive, and some never did.
Robot vacuum maker Roborock did say it’s working to support Matter as a top priority. “Though the partnership is still ongoing and a timeline is not solidified, we foresee that Matter support will be integrated into our models as soon as the first half of 2024,” Marcus Lai of Roborock tells me.
He says the integration will roll out in phases, with certain models getting support sooner, either built in when you buy it or via a firmware update. The other big robovac manufacturer, Ecovacs, tells me it’s planning to add Matter to its new products. Spokesperson Daniel Turk says the company is “working hand-in-hand with the CSA to integrate Matter into upcoming Deebots.”
While more device types are a good thing to help push the standard forward, there are still several big holes to fill. Matter now supports over 20 categories, including door locks, thermostats, smart lighting, security sensors, and smart shades. But cameras are still missing, as are security systems, two large components of the smart home today. Plus, there are more home appliances that need to be added, including a big one: ovens.

Another important omission from the new release: new features for existing devices. We’re still waiting on support for dynamic lighting effects (including adaptive lighting) and energy management, both of which the CSA has said are on the roadmap. These are features that will really help make Matter, well, matter to smart home users.
The only notable new consumer-facing feature in Matter 1.2 is one that adds support for smart door locks that use a latch system, a common type in Europe. There are also several new building blocks that should make it easier for developers and platforms to work with Matter devices and add more device types in the future.
These include allowing devices to describe their appearance in Matter ecosystems (i.e., “I’m a bronze door lock” or “I’m a brown light switch”), the addition of semantic tags (which could help with things like energy management and support for smart buttons), and support for generic operational states (to make it easier to add certain new device types in the future). The full spec can be viewed here.
Along with the new spec, the CSA also announced an effort called Ecosystem to Ecosystem that will address the “initial challenges” of multi-admin, the biggest being that it doesn’t work half the time.
Chris LaPré, head of technology at the CSA, explained to me that the effort is designed to fix the problem of ecosystems not directly communicating, i.e., an Apple HomePod won’t talk to a Google Nest Hub. “Currently, the solution is multi admin, where, say, I’m a smart switch, I’m going to talk to both separately,” says LaPré. “With Ecosystem to Ecosystem, if I pair my smart switch to both sides and then I change it to ‘kitchen light’ on this side, it should make it ‘kitchen light’ on the other side.” The groundwork is in place to allow this better interoperability, says LaPré, but they are still working on its implementation.
New device types should bring much-needed momentum to Matter and address the complaints of some existing smart home users that it has yet to add much to the experience other than headaches. But this hinges on manufacturers adding it to their products.
