Does Home Assistant Support Matter and Thread?
Yes. Home Assistant supports both Matter and Thread, and it has since 2023. Home Assistant can act as a Matter controller—the brain that commissions and controls Matter devices—and it can either provide its own Thread border router or borrow one you already own. The two technologies do different jobs: Matter is the application standard that lets devices speak a common language, while Thread is one of the low-power networks Matter devices can run on (Wi-Fi is the other). Home Assistant handles both, but the setup details depend on which Home Assistant installation type you run and what hardware is in your home.
Matter support in Home Assistant
Matter is a first-class, officially supported integration in Home Assistant. Once it's set up, Home Assistant becomes a Matter controller on your network, meaning it can commission (add) Matter devices and control them directly—lights, plugs, sensors, locks, thermostats, and more—using the standard rather than a cloud account for each brand.
The mechanics depend on how you installed Home Assistant:
- Home Assistant OS or Supervised: Matter runs through the official Matter Server add-on, which Home Assistant can install for you. This is the smoothest path and what most users run on a dedicated device like a Raspberry Pi, Home Assistant Green, or Home Assistant Yellow.
- Container or Core installs: There's no add-on system, so you run the Matter Server as a separate container yourself and point the integration at it. It works, but it's a manual job.
Commissioning a Matter device usually needs Bluetooth to get the device onto your network for the first time. The Home Assistant companion app on your phone can use the phone's Bluetooth to do this, which sidesteps the need for your Home Assistant box to be physically near the device.
Thread support in Home Assistant
Thread is a low-power mesh radio network—conceptually similar to Zigbee—that many Matter devices use instead of Wi-Fi. Thread devices can't reach your network on their own; they need a Thread border router to bridge the Thread mesh to your regular IP network. Home Assistant handles Thread in two ways.
1. Home Assistant as the Thread border router
With the right radio hardware, Home Assistant can be the border router by running the OpenThread Border Router add-on. The most common hardware for this is the Home Assistant Connect ZBT-1 (formerly SkyConnect) USB stick flashed with Thread firmware, or a Home Assistant Yellow. One caveat: a single radio generally does either Zigbee or Thread at a time, so if you're already using that stick for Zigbee, you'll want a second radio for Thread.
2. Home Assistant using a border router you already own
You may not need new hardware at all. Several popular devices act as Thread border routers, and Home Assistant can use them to reach Thread devices. These include recent Apple TV and HomePod models, some Google Nest hubs and Wi-Fi units, and certain Amazon Echo speakers. Home Assistant's Thread integration can detect these on your network and, in many cases, share Thread network credentials so everything joins one mesh.
If you're not sure what you already have, our guide to the best Thread border routers you may already own walks through the usual suspects, and what a Thread border router actually is explains the role in plain terms.
What you need to get started
- 1Run Home Assistant OS or Supervised so the Matter Server add-on is available
- 2Install the Matter Server add-on, then add the Matter integration
- 3Make sure a Thread border router exists—either flash a Connect ZBT-1/Yellow or rely on an Apple, Google, or Amazon router
- 4Use the Home Assistant mobile app's Bluetooth to commission each Matter device with its pairing code
For Matter-over-Wi-Fi devices, you can skip the Thread parts entirely—those connect over your normal Wi-Fi and only need the Matter controller. For Matter-over-Thread devices, the border router is the piece that can't be skipped.
Matter-over-Thread vs. Matter-over-Wi-Fi in Home Assistant
- Needs a Thread border router on the network
- Very low power—great for battery sensors and locks
- Joins a mesh, so range extends through mains-powered Thread devices
- No border router needed; uses your existing Wi-Fi
- Higher power draw, better suited to plugged-in devices
- Shares airtime with everything else on 2.4GHz Wi-Fi
Both paths end up controlled the same way once added to Home Assistant. The practical difference is the radio underneath and what infrastructure each one requires. If your Wi-Fi is congested, pushing more devices onto it can cause lag—our notes on 2.4GHz vs. 5GHz for smart-home devices and a stable smart-home Wi-Fi setup can help you decide.
Known rough edges
Matter and Thread are still maturing, and Home Assistant inherits some of that friction:
- Cross-vendor Thread credential sharing isn't always seamless. Apple and Google have historically kept their Thread networks somewhat separate, so getting every border router onto one shared mesh can take manual steps in Home Assistant's Thread panel.
- Some device features lag behind. A device may expose its core functions over Matter while brand-specific extras stay locked to the manufacturer's own app or integration.
- Commissioning hiccups are common across all platforms—usually Bluetooth range or a device that's already paired elsewhere and needs a factory reset first.
If a Matter device keeps dropping, the cause is often network-level rather than Matter itself—see our guides on devices that keep going offline and stabilizing a hub that keeps disconnecting.
Frequently asked questions
Do I need a separate hub to use Matter with Home Assistant?
Not for Matter-over-Wi-Fi devices—Home Assistant itself is the controller. For Matter-over-Thread devices you need a Thread border router, but that can be a device you already own or a USB radio in your Home Assistant box rather than a dedicated hub. Our overview of whether you still need a smart-home hub covers the trade-offs.
Does Matter in Home Assistant work without the internet?
Yes. Matter is a local standard, so Home Assistant commissions and controls Matter devices on your own network. Control continues during an internet outage, though initial commissioning and some manufacturer features may still want a connection.
Can Home Assistant share Thread devices with Apple, Google, or Amazon?
Often, yes, because Matter supports multiple controllers at once. The Thread mesh can be shared across border routers, and a Matter device can be added to several ecosystems using additional pairing codes—though cross-vendor credential sharing can still need manual setup.
Which Home Assistant install type is best for Matter and Thread?
Home Assistant OS (or Supervised) is the easiest, because the Matter Server and OpenThread Border Router add-ons are available with a few clicks. Container and Core installs work but require running the Matter Server yourself.
