MatterIndex

Specification-based · updated continuously

Will it actually work with what you already own?

CompatGrid is a maintained index of Matter and Thread interoperability — which devices pair with which hubs, which need a bridge, and which quietly do not work at all. Every entry is checked against published specifications and dated.

Four ways into the same index. The tools and the tables are built from one data set, so they never disagree with each other.

  • Tool

    Apple Home, Google Home, Alexa, SmartThings or Home Assistant — scored against your constraints, not ours.
  • Reference

    Matter, Thread, Zigbee, Z-Wave and Wi-Fi, compared field by field with the trade-offs stated plainly.

What the data looks like

The ecosystem support matrix, in full: 5 platforms against 4 capabilities, every cell carrying the vendor page it was read from and the date it was checked. Where no vendor sentence could be found, the cell says Unverified rather than guessing — 6 of 20 currently do.

Apple HomeSupported 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.Not yet verified against a published specification. UNVERIFIED. No Apple page consulted on this date states whether an accessory paired to Apple Home may also be added to another Matter ecosystem.
Google HomeSupported 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.Not yet verified against a published specification. UNVERIFIED. Google states Matter lets users set up a device with their favourite platforms, which describes the device rather than whether Google Home shares an accessory it has already commissioned.
Amazon AlexaSupported 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.
SmartThingsNot yet verified against a published specification. UNVERIFIED. Samsung states its built-in SmartThings Hub supports Matter, Thread and Zigbee technologies, which names no Matter transport.Not yet verified against a published specification. UNVERIFIED. Matter and Thread are listed side by side as hub technologies, which is not the same statement as Matter commissioning over Thread.Not yet verified against a published specification. UNVERIFIED. No Samsung or SmartThings page reachable on this date describes a SmartThings hub as a Thread border router.Not yet verified against a published specification. UNVERIFIED. No SmartThings document consulted addresses sharing a commissioned Matter device with a second ecosystem.
Home AssistantSupported 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.

Compiled from the platform documentation cited on each entry. Every cell checked on or after 2026-08-01. 6 of 20 cells are marked Unverified — no published vendor statement was found for them, so nothing is asserted either way. Support can change with a firmware release; check the dated entry before buying.
