Does Home Assistant support Matter? Which Matter devices work with Home Assistant

Yes. Home Assistant has a built-in Matter integration and runs its own Matter controller. MatterCheck rates Home Assistant as pairing all 24 Matter device types we track, and every one can start a Home Assistant automation — the only platform we track where that's true. Of the 24 rows, 18 are High confidence, the most of any platform; the six Med rows are mostly device types with no Matter product, or no consumer product, anyone has tested yet, plus appliances where controls depend on the device.

What you need for Matter in Home Assistant

Home Assistant runs its own Matter controller through the Matter Server app, and Home Assistant OS is the only supported install. For pairing, new Matter devices are added with the Home Assistant Companion app on a phone; the phone app acts as the commissioner and passes Wi-Fi or Thread credentials to the new device over Bluetooth LE during setup.

Wi-Fi and Ethernet Matter devices need no Thread border router. Thread devices need at least one Thread border router near them: an Apple or Google border router works, and it can't read the encrypted Matter traffic, or Home Assistant itself can be the border router with a Connect ZBT-1, ZBT-2 or SkyConnect plus the OpenThread Border Router app. Home Assistant also warns that IPv6 multicast and mDNS must flow freely — VLANs, multicast filtering or broken IGMP snooping can break adding and control.

Two setup cautions are worth planning around. Home Assistant's Matter OTA firmware updates don't work for Thread devices behind Apple border routers; the update fails with "Target node did not process the update file." A Thread logo isn't the same thing as Matter support, since some Thread devices are HomeKit-only. Bridges such as Hue Bridge, Aqara Hub M2, SwitchBot Hub 2 or IKEA Dirigera can expose non-Matter devices over Matter, but often with fewer features than native integrations — for example, Hue over Matter gives only basic light control in Home Assistant.

See the Matter hubs page for how Home Assistant's controller and Thread approach compare with the other platforms.

Home Assistant Matter support at a glance

Yes means Home Assistant does that, No means it doesn't, and Partial means only some devices or features work. High confidence means an official statement covers the feature plus a dated hands-on test of that device type on Home Assistant; Med usually means the type is supported in docs or code but no product, or no consumer product, has been tested. The No values in the automation-action column are sensors, meters and buttons — they have nothing to control.

Lights, plugs and buttons

Lights are a strong area for Home Assistant. On/off lights, dimmable/colour lights and colour-temperature lights are all High confidence. A 2026-08-12 chrissmart.de test of an IKEA KAJPLATS bulb added it by Matter QR code, then controlled on/off, dimming and colour temperature and used two button automations to switch it. A 2026-01-05 owner report found Govee Matter downlights could be controlled one light at a time from the colour wheel, though scenes that set colour and brightness together could be hit-or-miss unless brightness and colour were sent separately. Some Linkind Matter RGBTW bulbs expose only brightness in Home Assistant (HA), while others show full colour controls.

Matter plugs also rate High. In a 2026-08-11 chrissmart.de GRILLPLATS test and a 2026-05-18 AnalisisGadgets GRILLPLATS test, HA exposed switch control and energy, power, voltage and current entities; energy entities may first appear under Diagnostics. Buttons pair directly and appear as event entities. Control is Partial because a button has nothing to operate, but the button entity's event type can start automations. In a 2026-02-18 Courtney Rosenthal test, an IKEA BILRESA directly paired over Matter/Thread triggered a lamp from pressed once, twice, hold and release events. Use the button entity's event type rather than device triggers; ongoing scroll progress isn't exposed in stock Home Assistant.

For more depth, see Matter light bulb support and Matter smart plug support.

Matter sensors in Home Assistant

Contact sensors, motion/occupancy sensors, temperature/humidity sensors, leak sensors, smoke/CO alarms, air quality sensors and light sensors all rate High. They all start Home Assistant automations, and none can be an automation action because they're read-only sensor entities.

The evidence includes dated hands-on tests in Home Assistant: IKEA MYGGBETT contact sensors reported open/closed quickly in a 2026-01-28 Techtest hands-on; an Aqara W200 presence sensor worked as a YAML automation trigger in a 2026-04-18 ChrisHansenTech test; an IKEA KLIPPBOK leak sensor shared from Apple Home into Home Assistant drove leak-alert and dry-reset automations in a 2026-03-01 Kiwi Smart Tech test; and Sensereo Matter smoke/CO alarms triggered critical phone-alert automations in a 2026-09-20 raspberry.tips test.

Other dated tests cover the rest: an IKEA TIMMERFLOTTE temperature/humidity sensor added by Matter QR in a 2026-07-19 Teknik i Hemmet test, IKEA ALPSTUGA air quality monitors showing CO2, PM2.5, temperature and humidity in 2026-02-20 TechteamGB and 2026-07-15 The Smart Home Blog tests, and an Aqara FP300 giving an illuminance sensor in a 2026-01-30 SmartHomeScene test. Heiman Matter smoke alarms in a 2026-06-11 SmartHomeScene test exposed smoke, fault, battery, mute and self-test entities with immediate alerts.

The trigger types cover what you'd expect: binary sensor Door, Motion detected/cleared and Occupancy detected/cleared triggers; numeric-state triggers for temperature, humidity, illuminance and air quality; dedicated Smoke detected and Carbon monoxide detected triggers; and air quality threshold triggers for CO2, PM2.5, VOC and similar levels. Watch for devices that update rarely — some humidity and lux readings update too infrequently for tight automations, and some IKEA Thread sensors had subscription timeouts or missed events.

Locks, thermostats, blinds, fans and robot vacuums

Locks, thermostats, window coverings, fans/air purifiers and robot vacuums all rate High with full pairing, control, trigger and action support in Home Assistant. For locks, a 2026-09-16 Nuki Smart Lock Ultra test showed lock/unlock and door sensor entities plus an unlock-triggered light automation, and a 2024-07-13 Aqara U200 test repeatedly locked and unlocked from HA. Nuki doesn't expose Matter PIN commands over Matter.

Thermostats map to Home Assistant's Climate domain. A 2025-08-11 Eve Thermo test shared from Apple Home showed the current temperature and set the target temperature from the thermostat card, and the Aqara W200 test exposed current/target temperature, HVAC mode and humidity. In our matrix, Home Assistant is the only platform where Matter thermostats are High confidence; on Apple Home and Alexa, whether a thermostat can start an automation is still Unknown. The started heating/cooling trigger requires the thermostat to report running state; owner reports say Nest over Matter doesn't expose it. Vendor schedules and presets aren't included.

Blinds use the Cover domain, with open, close, position, stop, toggle and tilt actions. A Mighty Gadget SmartWings shade test used shade state as an automation condition and found the automations reliable. The trigger finding rests on Home Assistant's Cover docs and code, because no hands-on test of a shade's state starting an HA automation was found.

For fans and purifiers, SwitchBot joined Works with Home Assistant on 2025-06-26 with certified standalone Matter air purifiers, and owner reports show a Govee H1310 ceiling fan working over Matter with fan presets and dimming. Some SwitchBot purifiers failed Matter pairing in Home Assistant between 2025-10 and 2025-11. Robot vacuums got start, pause, stop, dock, clean mode, operating state and errors in a 2025-12-24 MESH Roborock test, and HA 2026.3 added room cleaning for Matter vacuums from automations. A SwitchBot K20+ Pro is Works with Home Assistant certified as a standalone Matter vacuum (2025-06-26), but the MESH test didn't include an automation, so the trigger rests on entity exposure and official release coverage.

See smart locks, thermostats, blinds and shades and robot vacuums.

Where Home Assistant is only Med: appliances and the long tail

Six rows are Med confidence. The most common reason is that Home Assistant's docs or code support the Matter device type, but no product — or no consumer product — exists for someone to test.

Appliances are Partial for control and action because what you can operate depends on the device. A Bosch dishwasher connected through a Matter bridge in a 2025-04-30 Smart Home Centre test exposed operational state, mode select, start/pause/resume/stop and a power switch, and a Matter Alpha report says HA 2025.8 added Matter temperature control for fridges, ovens, washers and cooktops. But a Midea Matter window AC exposed only cool/off modes, remote start is gated by the appliance, and oven/cooktop support rests on code rather than real-product tests.

Pumps and water heaters are the clearest documentation-only rows. Home Assistant's Matter integration page lists Pump and Water heater, and Home Assistant's code gives pumps a power switch and its docs list a matter.water_heater_boost action, but no Matter pump is sold, and the Matter Survey Water Heater listing (checked 2026-10-18) shows zero devices implementing it.

Water valves are supported in Home Assistant docs and code, and a developer test valve dated the close-command fix released in HA 2025.8, but no consumer Matter valve has been tested in HA. Speakers expose only mute, from HA 2025.11, and volume, from HA 2026.1 — not media playback — and no certified Matter speaker has been independently tested. A Home Assistant code reviewer said on 2025-10-06 they knew of no officially certified Matter speaker, and a 2026-08-23 Matter Survey listing shows 4 devices implementing the Speaker type, all Philips Smart TVs. Pressure sensors are supported in HA code, but there's no dated test of a standard Matter pressure sensor; Eve Weather's pressure arrives through Eve's own data field, not the standard Matter pressure type.

Energy meters are High, with one caveat: the evidence is plugs with built-in meters — Eve Energy Works with Home Assistant certification plus IKEA GRILLPLATS plug hands-ons — not a standalone Matter energy meter tested in Home Assistant. It's still the strongest energy meter row we track: Home Assistant is the only platform where a Matter energy meter can start an automation (SmartThings is Partial; Apple Home, Google Home and Alexa are No), and readings feed the Home Assistant Energy dashboard. A 2026-08-11 chrissmart.de energy-surplus automation switched a GRILLPLATS plug.

Which Matter devices can start a Home Assistant automation?

All 24 device types MatterCheck tracks can start a Home Assistant automation. That's Home Assistant's biggest edge: any Matter entity's state is an ordinary HA entity, so Home Assistant's trigger system can use it. Buttons work a little differently — you trigger on the button event entity's event type, not a device trigger — as Home Assistant's event entity docs describe.

As actions, 13 device types are supported: on/off lights, dimmable/colour lights, colour-temperature lights, plugs/outlets, door locks, thermostats, window coverings, fans/air purifiers, robot vacuums, pumps, water valves, speakers and water heaters. Appliances are Partial. The other ten are read-only: buttons, contact sensors, motion/occupancy sensors, temp/humidity sensors, leak sensors, smoke/CO alarms, air quality sensors, light sensors, energy meters and pressure sensors.

The practical use is automation placement. If you share a Matter device into Home Assistant and another platform, Home Assistant is where to build automations other platforms can't start — for example from a robot vacuum's state (No as a starter on Apple Home, Unknown on Alexa) or a thermostat's (Unknown as a starter on Apple Home and Alexa). See the multi-admin guide for the full walkthrough.

If Matter devices won't pair or go unavailable

Most reported fixes come down to networking. Matter uses IPv6 multicast and mDNS, so VLANs, multicast filtering or broken IGMP snooping can block adding or control. If a Thread device won't commission, retry — a 2026-01-28 Techtest MYGGBETT test succeeded after commissioning retries. A 2026-05-18 AnalisisGadgets GRILLPLATS test failed to pair until a router reboot. Owner reports for some IKEA Thread sensors describe subscription timeouts or missed events, with suggested fixes around Thread network or firewall settings. These are reported fixes, not guarantees.

Home Assistant's own docs also call out the OTA limitation: Matter firmware updates for Thread devices behind Apple border routers fail with "Target node did not process the update file."

How Home Assistant compares with other Matter platforms

Across the 24 tracked device types, Home Assistant pairs all 24, all 24 can start an automation, and 18 rows are High confidence. SmartThings also pairs all 24 and has 23 automation-trigger rows, with 15 High. Apple Home pairs 17, starts 14 and has 15 High. Google Home pairs 21, starts 17 and has 11 High. Amazon Alexa pairs 16, starts 6 and has 4 High.

So Home Assistant has the most High-confidence rows and is the only platform where every tracked type can start an automation. It's fair to note that SmartThings matches its pairing breadth, and Apple Home ties SmartThings on High rows, but Home Assistant still leads on both trigger coverage and High-confidence evidence. See the live platform matrix or the full five-platform comparison; also see Apple Home, Google Home and Amazon Alexa. Home Assistant's Matter integration page lists the broad entity categories behind these numbers. Home Assistant's Climate docs list thermostat triggers such as mode changed and target temperature changed; together with dated tests, that's why its thermostat row is High while every other platform's thermostat row is Med.

Use Home Assistant alongside Apple Home, Google Home or Alexa

Matter lets one device join Home Assistant and Apple Home, Google Home, Alexa or SmartThings at the same time, but each platform needs its own Matter controller. Home Assistant says the standard requires each device to support at least 5 fabrics at once.

To share a device already in Home Assistant: Settings → Connectivity → Matter → Devices → device → Share device. To add a device already in another app to Home Assistant: Add device → "Yes. It's already in use." and enter that app's sharing code. Don't reuse the printed QR/setup code for a second platform; make a new temporary pairing code in the app the device is already in. To remove a controller from Home Assistant's side, open the device, choose Manage fabrics and remove the controller; for Apple Home, also remove the Keychain entry. Sharing gives every platform the same Matter device, but not every platform supports every Matter device type or feature.

Two dated tests shared devices from Apple Home into Home Assistant this way: the 2026-03-01 IKEA KLIPPBOK leak sensor and the 2025-08-11 Eve Thermo. See the multi-admin guide for the full walkthrough, including Home Assistant's sharing steps and Amazon's pairing-code guidance.

How we checked

These values come from the MatterCheck matrix v1.14, with Home Assistant values last checked between 2026-10-16 and 2026-10-19. High confidence requires an official statement covering the feature plus a dated hands-on test of that device type on Home Assistant; a pairing-only test doesn't count. Works with Home Assistant certification and code support count as official evidence, but not as a hands-on test. See the methodology and device type pages for details.
