The Matter Smart Home Standard Explained: Will Your Devices Work Together?
For years, buying a smart plug or a smart bulb meant first deciding which ecosystem you belonged to. The Matter smart home standard was created to end that. It is a shared language that lets devices from different brands talk to the same apps and controllers, mostly over your home network rather than through a company's cloud. This guide explains what Matter does, what it does not do, and what to check before you buy.
What Matter is, in plain terms
The CSA, the industry body that also maintains Zigbee, describes Matter as "one protocol to connect compatible devices and systems with one another" (CSA, Build With Matter). Its official FAQ calls it an open smart home protocol built on existing, familiar technologies, and is clear that it does not replace your platform: most major smart home platforms support Matter, so you keep using Alexa, Google Home, Apple Home or SmartThings.
Think of it this way. Your platform is still the app and voice assistant you use. Matter is the agreed way the device and the platform speak to each other. Before Matter, a manufacturer had to build and certify separate integrations for each ecosystem. With Matter, a certified device should work with any platform that supports that type of device.
The CSA's launch announcement on 4 October 2022 listed Amazon, Apple, Comcast, Google, Samsung SmartThings and Signify among the member companies that contributed to the standard, and opened a certification programme with eight authorised test labs.
How Matter devices connect
Matter is an application layer. It sits on top of ordinary network technologies rather than inventing a new radio. According to the CSA, the first release ran over Ethernet, Wi-Fi and Thread, and used Bluetooth Low Energy for commissioning, which is the one-time setup step when you add a device (CSA, 2022).
| Network | Typically used for | What you need at home | Main trade-off |
|---|---|---|---|
| Wi-Fi | Plugs, bulbs, cameras, appliances: mains-powered devices that may move more data | Your existing Wi-Fi router | Higher power use, so less suited to small battery sensors; many devices add load to the router |
| Thread | Battery sensors, locks, buttons, blinds, some bulbs and plugs | At least one Thread border router | Needs a border router; range improves as you add mains-powered Thread devices |
| Ethernet | Hubs, bridges, TV boxes, some controllers | A spare port on your router or switch | Fixed location, needs a cable |
What a Thread border router does
Thread is a low-power mesh network: mains-powered Thread devices can relay messages for one another, which helps battery devices last longer. The Thread Group explains that a border router's only job is to pass traffic between that mesh and the rest of your network. Unlike a traditional hub, it does not translate between protocols, and the function can be built into smart speakers, displays, set-top boxes or even lighting products. If you have more than one border router, the network keeps working when one of them goes offline.
In practice, many people already own a border router without knowing it. Apple, for example, lists Apple TV 4K, HomePod (2nd generation), HomePod mini or a compatible third-party Thread border router as hubs for Thread accessories (Apple Support). Check your own platform's help pages for its current list.
Local control, and why you still need a controller
One of Matter's main design goals is local control. Commands travel across your home network instead of out to a company server and back. The CSA's FAQ notes the consequence: Matter is a local connectivity technology, so Matter-only devices need an internet-connected controller if you want to control them from outside the home. Some Matter devices may also have their own direct internet connection (CSA, Matter FAQs).
A controller is usually something you already have or will buy anyway: a smart speaker or display, a TV streaming box, a dedicated hub or, increasingly, a Wi-Fi router. Phones can act as controllers too. Apple says an iPhone on iOS 18 or later can add and control Matter accessories without a home hub, and iPhone 15 Pro and later models can control Thread accessories directly, though Apple still recommends a home hub for the best experience (Apple Support). A hub matters most for automations that must run when your phone is not at home.
Matter makes devices speak the same language. It does not make every app offer the same features, so the platform you choose still shapes what you can do.
Multi-admin: using more than one platform at once
Multi-admin is the feature that most directly answers the question in this article's title. The CSA describes it as letting you connect Matter devices to multiple platforms, apps or other control points, so you do not have to pick a single controller (CSA, All about choice). A household with both iPhones and Android phones can, for example, add the same smart plug to Apple Home and Google Home.
In practice you add the device to your first platform by scanning its setup code, then use that app's option to share or pair with another app, which generates a new code for the second platform. Apple's support page describes this for devices already paired with another app (Apple Support).
The standard has continued to smooth this out. Matter 1.4 added Enhanced Multi-Admin, which the CSA says is designed to let devices join multiple ecosystems with a single user consent, though device makers can choose whether to implement it (CSA, Matter 1.4). Matter 1.6 introduced Joint Fabric, which allows several user-authorised controllers to co-administer one shared Matter network (CSA, Matter 1.6). Support for these newer features depends on both your devices and your platforms being updated.
Which devices Matter covers
Matter has grown in steps. The table summarises the main releases, using the CSA's own announcements.
| Version | Announced | Notable additions |
|---|---|---|
| 1.0 | October 2022 | Lighting and electrical, HVAC controls, blinds and shades, safety and security sensors, door locks, media devices including TVs, controllers and bridges (source) |
| 1.2 | October 2023 | Nine new device types: refrigerators, room air conditioners, dishwashers, laundry washers, robotic vacuums, smoke and CO alarms, air quality sensors, air purifiers and fans (source) |
| 1.4 | November 2024 | Solar panels, batteries, heat pumps and water heaters; device energy management; in-wall switches; certifiable home routers and access points that include a Thread border router; longer battery life for sensors and buttons (source) |
| 1.5 | November 2025 | Cameras, closures (gates, garage doors, awnings and more), soil sensors, and energy tariff and carbon data (source) |
| 1.6 | June 2026 | No new device categories; NFC-based setup, Joint Fabric and thermostat suggestions (source) |
Two cautions follow from this table. First, a device type being in the specification does not mean every platform supports it yet; platforms add device types on their own schedules. Second, the specification and the products lag each other. Matter 1.5's camera support, for example, was made available to Alliance members in November 2025, and certified cameras have to be built and tested after that.
If you are planning an energy-focused home, the 1.4 and 1.5 additions are the most interesting: they give solar inverters, batteries, heat pumps and EV chargers a common way to share energy and tariff data. Our guide to designing an eco-friendly smart home ecosystem covers how to plan automations around that.
What about my existing Zigbee or Z-Wave devices?
Matter does not make older devices speak Matter by themselves. The CSA's FAQ says there is no native interoperability between Matter and Zigbee devices, but Matter supports bridges that expose devices using other protocols, such as Zigbee or Z-Wave, to Matter controllers (CSA, Matter FAQs). If your current hub is updated to act as a Matter bridge, your existing sensors and bulbs may appear in other Matter platforms without replacing them.
The FAQ also says many existing smart home products can be updated to support Matter through software, but whether a given product receives an update depends on its hardware and on the manufacturer. Do not buy a device on the promise of a future Matter update unless the manufacturer has published a date or a list of supported models.
Security and privacy
Matter builds security into setup. The CSA says data is encrypted and each device has a unique identity, which helps keep unauthorised devices off your network (CSA, Matter FAQs). Local control also means fewer commands need to leave your home.
That does not make every Matter device private by default. A device can still have its own app, cloud account and data collection on top of Matter. Read the manufacturer's privacy policy, especially for cameras and devices with microphones, and keep firmware up to date. The same principle applies to appliances with cameras, such as the robot vacuums discussed in our guide to choosing a robot vacuum.
A buying checklist
- Look for the Matter logo. The CSA says only certified devices may carry it (source). You can also check a product against the CSA's certified products listing.
- Check the device type on your platform. Confirm on your platform's help pages that it supports that kind of device over Matter, not just the brand.
- Check the network. If the box says Thread, make sure you have a Thread border router, or plan to buy one.
- Check what is Matter and what is app-only. Some advanced features, such as energy history or custom scenes, may still live only in the manufacturer's app.
- Keep the setup code. Photograph the QR code or numeric code on the device or manual before you install it somewhere hard to reach.
- Plan for power and efficiency. A smart plug can switch an inefficient appliance on and off, but it cannot make it efficient. For large appliances, our guide to BEE star ratings explains how to compare running costs.
The bottom line
Matter is a real improvement: certified devices can be set up with a code, controlled locally, and shared across Apple, Google, Amazon and Samsung platforms through multi-admin. It does not remove the need for a controller, it does not turn old Zigbee or Z-Wave gear into Matter devices without a bridge, and it does not guarantee that every platform supports every device type on day one. Look for the logo, check that your platform supports the specific device type, make sure you have a Thread border router if the device uses Thread, and treat promised future updates with caution.
Frequently asked questions
Do I need a hub for Matter devices?
You need a controller for remote access and reliable automations, but it is often a device you already own, such as a smart speaker, display, TV box or newer router. Thread devices also need a Thread border router, which many of these controllers include.
Will a Matter device work with both Alexa and Google Home?
It should, if both platforms support that device type. Matter's multi-admin feature lets you add the same device to more than one platform at the same time.
Does Matter work without the internet?
Matter is designed for local control, so devices can respond to commands on your home network. Remote control from outside the home needs an internet-connected controller, and some voice assistants rely on the internet to understand commands.
Is Thread the same as Matter?
No. Thread is a low-power mesh network, while Matter is the application standard that runs on top of Thread, Wi-Fi and Ethernet.
Which version of Matter should I look for?
The version matters less than whether your platform supports the device type. The CSA released Matter 1.6 in June 2026; newer versions add features, but older certified devices continue to work.
