Quick summary
Matter is a smart home interoperability standard — it lets devices from different brands work together across Apple Home, Google Home, Amazon Alexa, and Samsung SmartThings. Thread is a separate, low-power mesh radio protocol that many Matter devices use as their transport layer. Understanding the difference between them is the starting point for building a smart home that actually holds together.
If you're already in the Apple or Google ecosystem and own a recent hub, you likely have everything you need to start buying Matter devices today. If your setup is older or mixes brands, this guide will help you identify the one or two gaps that are preventing it from working reliably.
The core concept: what Matter actually is
Matter is an application-layer standard, not a radio protocol. It defines how smart home devices describe themselves, receive commands, and report state — the language, not the wire. A Matter-certified light bulb and a Matter-certified thermostat can talk to a Matter controller regardless of which company made them.
The Connectivity Standards Alliance (CSA) — the same organization that built Zigbee — published Matter 1.0 on October 4, 2022. Amazon, Apple, Google, and Samsung SmartThings were founding members. Today, over 794 companies are CSA members.
The key design decision: Matter runs on top of standard IP networking. That means it can travel over your existing Wi-Fi, over a wired Ethernet connection, or over a low-power mesh radio called Thread. The device chooses the transport that fits its needs; the Matter layer above stays the same.

Matter 1.5 is the current specification as of February 2026.
Matter is an application standard. Thread is a radio protocol. They are different layers. A device can use Matter over Wi-Fi, Matter over Thread, or Matter over Ethernet — all three are valid.
What is Thread, and how does it relate to Matter?
Thread is a low-power mesh networking protocol designed for battery-powered and low-energy devices. It runs on the IEEE 802.15.4 radio standard at 2.4 GHz — the same underlying radio technology as Zigbee — but with a key difference: Thread is IP-addressable via IPv6.
Because Thread is IP-addressable, Matter can run directly on top of it — no proprietary gateway or protocol translation needed. A Thread sensor is a native citizen of your IP network, and the Matter layer sits above it the same way it does on Wi-Fi.
Thread vs Wi-Fi for Matter devices:
| Factor | Matter over Thread | Matter over Wi-Fi |
|---|---|---|
| Power draw | Very low — ideal for batteries | Higher — needs constant radio |
| Range | Mesh extends range automatically | Single-hop to router |
| Latency | Low (~100 ms typical) | Low-to-medium |
| Best for | Sensors, locks, buttons, bulbs | Plugged-in devices, displays |
| Requires | Thread border router | Wi-Fi router |
For a door lock that needs two years of battery life, Thread is the right transport. For a smart plug that's always powered, Wi-Fi works fine.
Thread creates a self-healing mesh. When one node goes offline, traffic routes around it automatically. Add more Thread devices and the mesh gets stronger — each mains-powered Thread device also acts as a relay node.
How does Matter compare to Zigbee and Z-Wave?
Matter replaces the need for separate Zigbee and Z-Wave hubs, but it does not mean Zigbee and Z-Wave devices stop working.
Key differences:
| Matter | Zigbee | Z-Wave | |
|---|---|---|---|
| Protocol type | Application standard (IP-based) | Proprietary mesh | Proprietary mesh |
| Hub required | Matter controller (often built into speakers/routers) | Dedicated Zigbee hub | Dedicated Z-Wave hub |
| Ecosystem lock-in | None — works across all platforms | Partial (hub-dependent) | Partial (hub-dependent) |
| Battery life (sensors) | ~2 years (Thread, current gen) | ~3 years (mature standard) | ~2–3 years |
| Range | Medium (Thread mesh) | Medium | Long (~100 m open air) |
| Interference | Shares 2.4 GHz with Wi-Fi (Thread) | Shares 2.4 GHz with Wi-Fi | 800–900 MHz, avoids Wi-Fi |
Zigbee has a battery life edge over current-generation Thread hardware. Matter 1.4 introduced sleeping-device improvements, and newer chips (such as Nordic Semiconductor's nRF54 series) are closing that gap. For sensors shipping in 2025 and later, the difference is shrinking.
Z-Wave's 900 MHz band is a genuine advantage in dense Wi-Fi environments, but its ecosystem remains proprietary. If you have Z-Wave hardware you're happy with, a Matter bridge can bring it into your Matter network — you don't have to replace it.
If you're starting from scratch or adding new devices, Matter is the better long-term bet. If you have an existing Zigbee or Z-Wave investment, a bridge is almost always cheaper than replacement.
What devices support Matter in 2026?
Eight device categories were in Matter 1.0; Matter 1.5 (November 2025) expanded that to over 20, including cameras and motorized closures. Here's what's certified today:
Lighting and electrical: Smart bulbs, dimmable switches, plugs, outlets, relays — the most mature category, broadest device selection.
Locks and access: Door locks (keypad and keypad-free), garage door controllers, window sensors, door/contact sensors.
Climate: Thermostats, fans, room air conditioners, heat pumps (via 1.4).
Appliances: Dishwashers, laundry washers/dryers, robot vacuums, ovens, cooktops, extractor hoods, refrigerators.
Energy: EV chargers, solar inverters, battery storage systems, water heaters, smart meters.
Safety: Smoke and CO alarms, air quality sensors, water leak detectors.
Cameras (new in 1.5): Standard cameras, video doorbells, floodlight cameras, intercom units — with live streaming, two-way audio, and PTZ controls via WebRTC.
Closures (enhanced in 1.5): Motorized shades, curtains, awnings, garage doors, gates — now using a modular model that supports sliding, swinging, and tilting panel types.
Not yet supported natively: most video streaming platforms, traditional HVAC systems requiring proprietary integration, older intercom systems.
Before buying any device marketed as Matter-compatible, verify it at the CSA's Distributed Compliance Ledger (DCL) at csa-iot.org. Marketing claims and actual certification are not always the same thing.
Thread border routers: the piece most guides miss
A Thread border router is a device that bridges your Thread mesh to your IP network (Wi-Fi or Ethernet). Without one, Thread devices can form a mesh among themselves but cannot reach the internet or your Matter controllers. It's the most common reason a Matter over Thread setup fails — and the one piece most buying guides don't mention.
Border routers built into popular devices (as of early 2026):
| Device | Ecosystem | Thread version | Price |
|---|---|---|---|
| Apple HomePod mini | Apple Home | 1.3 (1.4 via tvOS 26, later 2026) | ~$99 |
| Apple HomePod (2nd gen) | Apple Home | 1.3 (1.4 via tvOS 26) | ~$299 |
| Apple TV 4K (3rd gen) | Apple Home | 1.3 (1.4 via tvOS 26) | ~$129 |
| Google Nest Hub (2nd gen) | Google Home | 1.3 | ~$100 |
| Google Nest Hub Max | Google Home | 1.3 | ~$230 |
| Google TV Streamer | Google Home | 1.3 | ~$100 |
| Amazon Echo (4th gen) | Alexa | 1.1–1.3 | ~$100 |
| Amazon Echo Hub | Alexa | 1.3 | ~$180 |
| Amazon eero 6+ | Alexa | 1.3 | ~$139 |
| Amazon eero Max 7 | Alexa | 1.3 | ~$600 |
| Amazon eero 7 | Alexa | 1.4 | ~$170 |
| Samsung SmartThings Station | SmartThings | 1.3 | ~$99 |
| IKEA Dirigera | IKEA | 1.4 | ~$65 |
The Thread 1.4 fragmentation problem — and its fix:
Prior to Thread 1.4, each brand's border routers created their own separate Thread mesh. An Amazon Echo and an Apple HomePod mini in the same home would each run a different Thread network. Devices had to choose one or the other. This caused connection failures, latency spikes, and general confusion.
Thread 1.4 (released September 2024) standardizes credential sharing. When a Thread 1.4 border router joins your home, it joins the existing Thread network instead of creating a new one. The result: one unified mesh across brands.
As of January 1, 2026, Thread 1.3 certifications for new border routers are no longer accepted. New hardware shipping now must be Thread 1.4 certified. The eero 7 and IKEA Dirigera are among the first widely available devices with Thread 1.4. Apple's rollout is expected with tvOS 26 later in 2026.
Practical implication: If you have a mixed-brand setup with older border routers, your Thread network is likely fragmented into separate islands. Replacing one or two key devices with Thread 1.4 hardware will consolidate them.
How does Matter multi-admin work?
Multi-admin is Matter's answer to ecosystem lock-in. It lets a single device be added to multiple platforms simultaneously — so your Matter lock can be controlled by Apple Home, Google Home, and Alexa at the same time without any of them conflicting.
Each ecosystem gets its own cryptographic binding called a "fabric." Most Matter devices support up to five fabrics, meaning up to five ecosystems can control the same device concurrently.
The pairing process works like this:
- Commission the device into your first ecosystem (scan the QR code in the Apple Home app, for example).
- In that same app, generate a "share" or "add to another platform" code — a one-time pairing code.
- Use that code in your second ecosystem's app (Google Home, Alexa, etc.).
- Repeat for additional ecosystems.
The device reports its state to all bound ecosystems in real time. Automations in any one ecosystem can trigger it.
You don't have to pair a device to multiple ecosystems. If you're fully in Apple Home, commission to Apple Home only. Multi-admin is for mixed households or anyone who wants redundancy.
Which platforms actually support Matter well?
The specification is one thing; implementation is another. In 2026, Matter support varies significantly across ecosystems.
Apple Home: Strong Matter controller. Supports Matter over Thread and Wi-Fi. Multi-admin implementation works reliably. Thread 1.4 rollout is expected with tvOS 26 (late 2026 for shipping devices). Missing: native support for some newer 1.4 device categories (heat pumps, solar systems).
Google Home: Matter controller since 2022. Thread border routers in Nest Hub (2nd gen) and above. Known limitation: some device categories in Matter 1.2 and above are not yet fully surfaced in the Google Home app. Generic switches (buttons), for example, are not available to Google Home users despite being in the 1.0 spec. Google has been slower than SmartThings on spec updates.
Amazon Alexa: Thread border routers in Echo (4th gen), Echo Hub, and eero devices. Amazon claims Matter 1.4 SDK support but implements a subset of features — some device types that are in the spec do not appear in Alexa. Alexa's automation engine is deeper and more flexible than Google's for complex routines.
Samsung SmartThings: Fastest to implement new Matter spec versions. SmartThings announced Matter 1.5 support within weeks of the specification release. The SmartThings Station includes a Thread border router. Best choice for users who want the latest device types earliest.
Home Assistant: Open-source platform with full Matter and Thread integration. Requires a dedicated Thread radio (sold separately as the Home Assistant SkyConnect/ZBT-1 dongle). Best for privacy-first, local-control users willing to invest in setup time.
The honest summary: no single platform implements the full Matter specification completely in early 2026. SmartThings is closest. Apple is the most polished consumer experience. Google lags on certain device types. Amazon works well but with gaps.
Common mistakes when setting up a Matter network
Assuming any hub is a Thread border router. Google Home mini, older Echo devices, and many Wi-Fi routers are not Thread border routers. Check the specific model before purchasing.
Buying Thread devices without a border router. Thread devices will not commission without one. If your ecosystem hub lacks a built-in border router, you need a dedicated one.
Mixing Thread 1.1/1.3 and Thread 1.4 border routers without understanding the result. Until all border routers in your home support Thread 1.4 credential sharing, you may have separate Thread meshes running. The fix is to replace older border routers or add at least one Thread 1.4 device to begin consolidation.
Expecting every feature to work across every ecosystem. A device's Matter certification confirms it meets the base standard. Platform-level features (like specific automation triggers or energy monitoring dashboards) depend on what each ecosystem app implements. Test the specific workflow you care about before committing to a full deployment.
Forgetting firmware updates. Matter devices depend on firmware to stay compatible with newer platform implementations. Devices that ship on Matter 1.0 firmware may not support features added in 1.2 or 1.3 without a manufacturer update — and not all manufacturers provide them. Check the manufacturer's update track record before buying.
Overloading a single Thread mesh. Matter 1.4.2 requires border routers to support at least 150 devices. Older border routers may max out earlier. In large homes or dense installs, plan for multiple border routers and check device limits.
Practical takeaways: who should upgrade now
If you're buying new devices and already own a hub from 2021 or later, start today. If your Zigbee or Z-Wave setup works and covers your device types, wait.
Upgrade now if:
- You're buying new smart devices and want them to work across platforms without proprietary hubs.
- You already have an Apple, Google, or Amazon ecosystem with a recent hub (2021+).
- You want local control — Matter devices work without internet by default.
- You're setting up a new home or doing a significant renovation and want future-proof wiring.
Wait if:
- Your existing Zigbee or Z-Wave setup works well and the devices you need aren't yet certified in Matter.
- You rely heavily on a device type Matter doesn't cover yet (some HVAC integrations, legacy intercom systems).
- You're in Google Home and specifically need button/generic switch support — wait for Google to catch up.
What to buy first: A Thread border router hub is the foundation. If you're already in the Apple ecosystem, a HomePod mini covers it. For Alexa, the Echo Hub adds a touchscreen and Thread support for $180. For a combined Wi-Fi router and Thread border router, the eero 7 handles both for $170.
Start with one or two Matter-over-Thread sensors or a smart lock to verify your setup works before committing a full deployment budget.
We've deployed Matter in residential installs ranging from single-room pilot tests to whole-home integrations. The most reliable results come from choosing one primary platform and adding multi-admin as a secondary convenience — not as the primary control path.

FAQs
Do I need Thread to use Matter?
No. Matter devices can connect over Wi-Fi, Thread, or Ethernet. Thread is optional — it's the best choice for battery-powered devices like sensors and locks because of its low power draw. Plugged-in devices like smart plugs and displays typically use Matter over Wi-Fi.
Is my existing smart home hub compatible with Matter?
It depends on the model and whether the manufacturer has released a Matter update. Most hubs released after 2020 — including Amazon Echo (4th gen), Apple HomePod mini, Google Nest Hub (2nd gen), and Samsung SmartThings Station — have received Matter support via firmware. Hubs from 2019 or earlier typically do not support Matter. Check the manufacturer's support page for your specific model.
Can one Matter device work with both Apple Home and Google Home at the same time?
Yes. This is called multi-admin. A single Matter device can be added to multiple ecosystems by generating a pairing code in one app and entering it in another. Each ecosystem gets independent control. Most Matter devices support up to five simultaneous ecosystems (fabrics).
What is a Thread border router and do I need one?
A Thread border router connects your Thread mesh network to your IP network (Wi-Fi or Ethernet). You need one if you plan to use any Matter-over-Thread devices. Many ecosystem hubs include one: Apple HomePod mini, Google Nest Hub (2nd gen), Amazon Echo (4th gen), Echo Hub, and eero devices all include built-in Thread border routers. If your hub doesn't have one, you need to add a device that does.
How many Matter devices can a single Thread network support?
Matter 1.4.2 requires Thread border routers to support addressing at least 150 devices. In practice, mesh capacity depends on the number of mains-powered nodes (which act as relays) versus battery-powered end devices. A well-designed mesh with 4–6 powered nodes can comfortably support 50–100+ end devices. For large installs, plan for multiple border routers and ensure a clear mesh topology.
