TL;DR: Matter is a free, open smart home standard from the Connectivity Standards Alliance (CSA) that lets lights, plugs, locks, thermostats, sensors and more work with Apple Home, Google Home, Amazon Alexa and Samsung SmartThings, often at the same time. Matter devices talk over Wi-Fi, Thread or Ethernet, are set up with a QR code, and can be controlled locally without a trip to the cloud. The newest version listed by the CSA is Matter 1.6.1; the latest release it formally announced is Matter 1.6 (June 2026).
If you’ve seen a little Matter logo on a smart bulb box and wondered what Matter smart home support actually means, here is the short version: it’s an attempt to end the “does this work with my assistant?” problem. Instead of buying a device that only works with Alexa or only with Apple Home, a Matter-certified device is meant to work with any Matter-compatible platform. This guide explains how Matter works, what Thread has to do with it, which devices are covered and whether it’s worth paying attention to when you shop.
What is Matter in simple terms?
Matter is a shared language for smart home devices. It’s developed by the Connectivity Standards Alliance, the industry group formerly known as the Zigbee Alliance, with companies including Apple, Google, Amazon and Samsung among its members. The first version, Matter 1.0, arrived in late 2022.
Before Matter, each ecosystem had its own rules. A device maker had to build separate support for HomeKit, Alexa and Google Assistant, and many skipped one or two. Matter replaces that patchwork with a single, certified standard: a device that passes Matter certification should work with every platform that supports Matter, without separate apps or “skills” for each one.
The three big ideas behind Matter
- Interoperability: one device, many platforms. A Matter plug can be added to Apple Home and Google Home at once.
- Local control: Matter runs over your home network using standard internet protocols (IP), so commands can travel directly from your phone or hub to the device instead of bouncing through a company’s servers.
- Security by design: every certified device carries a verifiable identity, and setup uses encrypted pairing. Matter 1.6 added partitioned certificate revocation lists so the system can scale as the number of devices grows, according to the Matter Handbook.
How does Matter work?
Matter is an application layer, the “language” devices speak. It doesn’t define its own radio. Instead it runs on top of network technologies you already know:
| Technology | Role in Matter | Typical devices |
|---|---|---|
| Wi-Fi | Carries Matter traffic for devices that need more bandwidth and have mains power | Smart plugs, cameras, appliances |
| Thread | Low-power mesh network for small devices; needs a Thread border router | Sensors, battery locks, bulbs, blinds |
| Ethernet | Wired connection for hubs and bridges | Bridges, hubs, routers |
| Bluetooth LE | Used during setup (commissioning), not for everyday control | Most new Matter devices |
| NFC | Optional setup method added in Matter 1.6, even before a device is fully powered | Bulbs, in-wall switches |
Because Matter is IP-based, it sits comfortably alongside your existing router. If you’re fuzzy on how your home network is put together, our guide to modem vs router is a good primer, and what Wi-Fi 7 is explains the newest Wi-Fi generation.
What is Thread, and do I need it?
Thread is a low-power wireless mesh protocol designed for small, often battery-powered devices. Each mains-powered Thread device can relay signals for others, so the network gets stronger as you add devices. To reach your phone and the internet, a Thread network needs a Thread border router, a role built into many recent smart speakers, streaming boxes and hubs from the big ecosystems. You only need one if you buy Thread-based Matter devices; Wi-Fi Matter devices connect straight to your router.
Setting up a Matter device
- Open your smart home app (Apple Home, Google Home, Alexa or SmartThings, for example).
- Choose to add a device and scan the Matter QR code on the device or its box, or enter the numeric setup code.
- Your phone hands the device your network details, usually over Bluetooth LE.
- Name the device and assign it to a room.
- To add it to a second platform, use the “share” or “pairing mode” option in the first app to generate a new code (more on that below).
Keep the setup code somewhere safe. Taking a photo of the QR code before you install a switch behind a wall plate saves a lot of hassle later. Recent versions also made setup easier: Matter 1.4.1 added a single QR code for multipacks, and Matter 1.4.2 added setup over Wi-Fi alone, per the Matter Handbook.
Multi-Admin: using one device with several ecosystems
Multi-Admin is one of Matter’s most useful features. It lets a single device be controlled by more than one “controller” at the same time. A household with an iPhone user and an Android user can both control the same Matter lamp from their own app and voice assistant.
The CSA has kept building on this. Matter 1.4 introduced Enhanced Multi-Admin, and Matter 1.6 added Joint Fabric, which the Matter Handbook describes as letting multiple user-authorized controllers co-administer one shared Matter network through a central datastore, so devices don’t need separate setup in each ecosystem.
What devices does Matter support?
Matter launched with the basics and has added new device types with almost every release. Here is how support has grown, based on the Matter Handbook and the CSA’s announcements:
| Version | Released | Key additions |
|---|---|---|
| 1.0 | 2022 | Lights, plugs, switches, locks, thermostats, blinds, sensors, TVs and media, bridges |
| 1.1 | May 2023 | Better support for battery devices that sleep |
| 1.2 | Oct 2023 | Robot vacuums, fridges, washers, dishwashers, smoke and CO alarms, air purifiers, fans |
| 1.3 | May 2024 | Energy reporting, EV chargers, water valves and leak sensors, ovens, cooktops, dryers |
| 1.4 | Nov 2024 | Solar, home batteries, heat pumps, water heaters, routers, Enhanced Multi-Admin |
| 1.5 | Nov 2025 | Cameras, closures such as gates and garage doors, soil sensors, energy tariffs |
| 1.5.1 | Mar 2026 | Camera, doorbell, chime and intercom improvements |
| 1.6 | Jun 2026 | NFC setup, Joint Fabric, thermostat suggestions |
The CSA’s specifications page also lists a Matter 1.6.1, which Matter Alpha reports finalizes Groupcast (to cut the “popcorn” delay when several lights switch on one after another) and adds volume and mute controls for doorbell chimes. Keep in mind that a platform has to update its software before new device types show up in your app.
Matter pros and cons
Pros
- Freedom to switch or mix ecosystems without replacing devices
- Faster, more reliable local control for many tasks
- Standardized, QR-code setup across brands
- Strong security requirements through certification
Cons
- Not every feature crosses over; advanced settings may still need the maker’s own app
- Thread devices need a border router
- Platforms adopt new Matter versions at different speeds
- Older non-Matter devices only join through a bridge, if at all
Is Matter worth it when buying smart home gear?
For most people, yes: if two similar devices cost about the same, the Matter-certified one is the safer bet because it won’t lock you into a single ecosystem. It matters most if your household mixes iPhones and Android phones, if you might switch voice assistants, or if you want devices that keep working locally when your internet is down.
Look for the Matter logo on the box and check whether the device uses Wi-Fi or Thread. If it’s Thread, make sure you have a compatible border router. Security also extends beyond the gadget itself; for your accounts, see what a passkey is, and for tap-to-pair tech on your phone, how NFC works.
The bottom line
Matter is the smart home industry’s common language. It lets devices from different brands work with Apple, Google, Amazon and Samsung platforms, keeps more control on your local network and makes setup as simple as scanning a QR code. It isn’t perfect yet, but with steady releases from Matter 1.0 to 1.6.1 it has become the label worth checking first when you buy smart home gear.
