What Apple's own published documentation states about Matter transports, Thread-enabled home hubs, and sharing accessories with other ecosystems.
Matter and Thread compatibility by ecosystem
What Apple Home, Google Home, Alexa, SmartThings and Home Assistant each document about Matter, cell by cell. Every verdict links to the vendor page it came from.
How we know this: our findings are based on published manufacturer specifications, certification records, and other cited sources. We have not personally used or tested these products. How we research.
| Ecosystem | Matter over Wi-Fi | Matter over Thread | Built-in border router | Multi-admin sharing |
|---|---|---|---|---|
| Apple Home | Supported natively. Apple documents provisioning an accessory onto Wi-Fi or Thread, as appropriate, during setup. | Supported natively. The same Apple provisioning documentation names Thread alongside Wi-Fi. | Supported natively. Apple names Apple TV 4K, HomePod (2nd generation) and HomePod mini as Thread-enabled home hubs. Of the current Apple TV 4K, only the Wi-Fi + Ethernet model lists Thread; the Wi-Fi model does not. | Supported natively. Apple documents adding a Matter accessory already paired with another app to Apple Home, and adding an accessory paired in Apple Home to a third-party Matter app. |
| Google Home | Supported natively. Google states that Matter devices use a supported network layer technology like Wi-Fi or Thread. | Supported natively. The same Google overview names Thread alongside Wi-Fi as a supported network layer. | Supported natively. Google lists Nest Hub (2nd gen), Nest Hub Max, Google TV Streamer (4K) and Nest Wifi Pro as Thread border routers among its Matter hubs. | Supported natively. Google documents sharing a device from Google Home to other Matter apps (Linked Matter apps & services) and adding one set up in another app. Each app needs its own Matter hub. |
| Amazon Alexa | Supported natively. Amazon states that compatible Echo devices support smart home devices connected using Matter over Wi-Fi and Matter over Thread. | Supported natively. Named explicitly in the same sentence as Matter over Wi-Fi. | Supported natively. Amazon lists Echo (4th Gen) with a Thread 1.1 border router, and Echo Hub, Echo Studio, Echo Show 10 (3rd Gen) and further models with Thread 1.3. | Supported natively. Amazon documents the Matter Multi-Admin feature for connecting a device to multiple smart home platforms, including Alexa. |
| SmartThings | Supported natively. Samsung documents its SmartThings hubs as Matter controllers; the 2015 hub supports Matter devices over Wi-Fi/LAN, and setup selects the Wi-Fi or Thread network. | Supported natively. Thread devices need a Matter controller that includes a Thread border router: the SmartThings 2018 Hub or Aeotec Smart Home Hub, or a third-party border router with the 2015 hub. | Supported natively. Documented for the SmartThings 2018 Hub (IM6001-V3P01) and Aeotec Smart Home Hub. Not established for SmartThings Station or Samsung TVs with a built-in hub. | Supported natively. Samsung documents sharing a Matter device from SmartThings to other platforms and adding one set up elsewhere. Each device can connect to at most 5 services. |
| Home Assistant | Supported natively. The Matter integration documents control of Matter devices on a local Wi-Fi or Thread network. | Supported natively. Same page; it adds that a Thread device needs a Thread border router near it. | Partially supported — some features unavailable. Conditional. Requires a Thread-capable radio such as Home Assistant Yellow or Connect ZBT-1, plus the OpenThread Border Router add-on. Not present in a bare install. | Supported natively. The Matter integration documents joining the same device to multiple controllers, naming Google Home, Apple Home and Home Assistant simultaneously. |

What the columns mean
- Matter over Wi-Fi
- The platform can add a Matter device that joins your home Wi-Fi network. Many plugs, bulbs and appliances use Wi-Fi.
- Matter over Thread
- The platform can add a Matter device that talks over Thread, a low-power mesh network used by sensors, locks and battery devices. Thread devices also need a border router on the network.
- Built-in border router
- The platform documents its own Thread border router, the bridge between Thread devices and your IP network: usually a hub, speaker or streaming box, or for Home Assistant a Thread radio plus an add-on.
- Multi-admin sharing
- A Matter device already set up in this platform can also be added to a second platform, so two apps control the same device.
