Apple Home vs Google Home vs Alexa for Matter: which supports the most device types?

Across the 24 Matter device types MatterCheck tracks, Home Assistant and SmartThings pair all 24, Google Home pairs 21, Apple Home pairs 17, and Amazon Alexa pairs 16. The bigger split is automations: Home Assistant can start automations from all 24, SmartThings from 23, Google Home from 17, Apple Home from 14, and Alexa from only 6 confirmed types. These values are dated and sourced, checked 2026-10-16 to 2026-10-19; many of Home Assistant's and SmartThings' long-tail rows are Med confidence, so the raw numbers need reading alongside the evidence.

Matter platform scoreboard

This is the headline comparison of pairing, app control, automation starters and confidence, counted from the current MatterCheck matrix values.

Read it as Yes vs everything else: Partial and Unknown are not full Yes. Confidence is equally useful because High requires an official statement covering the feature plus a dated hands-on test on that platform, while many Med rows rest on listings, code, docs, or owner reports.

The short answer for each platform

Home Assistant

Home Assistant has the broadest coverage in the matrix: it pairs all 24 Matter device types and can use all 24 as automation triggers. It also has the most High-confidence rows at 18, including the only High energy-meter row in the matrix. The caveat is concentrated in the long tail of pumps, water valves, speakers, water heaters, and pressure sensors: those rows are Yes but all Med because they rest on Home Assistant's docs and code rather than dated hands-on tests, and few or no consumer products of those types ship. See the live matrix for the latest Home Assistant rows.

SmartThings

SmartThings also pairs all 24 device types (see its official Matter device list) and starts automations from 23; energy meters are the only Partial trigger, because only meters built into plugs have been shown starting routines. Its 15 High rows are strong on core lighting, sensors, locks, blinds, fans, vacuums, and light sensors. The long-tail rows such as water valves, water heaters, and speakers rest on official listings, not positive consumer tests, so treat them as supported-on-paper until proven in your own setup.

Google Home

Google Home pairs 21 types (see Google's supported device list) and starts automations from 17, with 11 High rows. The gaps are water valves and water heaters, plus Partial appliances. Air quality and light sensors can start automations only through Google's Script Editor, not the app's normal automation editor, which is why those triggers are Partial. Read the full Google Home breakdown in Does Google Home support Matter?.

Apple Home

Apple Home pairs 17 types (see Apple's Matter accessory page) and starts automations from 14, with 15 High rows. Its strongest High areas are lights, plugs, buttons, contact, motion, temperature/humidity, locks, blinds, air quality, and light sensors. The clearest gaps are pumps, water valves, speakers, water heaters, and pressure sensors, plus a robot vacuum state that cannot start an Apple Home automation. See Does Apple Home support Matter?.

Amazon Alexa

Alexa pairs and controls the common types (lights, plugs, most sensors, locks, thermostats, blinds, fans and robot vacuums), but only 6 automation-trigger types are Yes: buttons, contact sensors, motion/occupancy, temperature/humidity, smoke/CO alarms, and door locks. Another 10 trigger values are Unknown, including on/off lights, plugs, thermostats, blinds, fans, robot vacuums, and air quality sensors. Pairing is also missing for pumps, water valves, energy meters, speakers, water heaters, and pressure sensors. See Does Alexa support Matter?.

Every device type, side by side

Each entry gives four values in order: pairs directly over Matter / control in the app / can start an automation / can be controlled by an automation, then the confidence. Y = Yes, N = No, P = Partial, U = Unknown. Click a device type for its sources.

Where all five platforms agree

There is a large common core. These 16 types pair directly on all five platforms: all three light types, plugs/outlets, switches/buttons, contact sensors, motion/occupancy, temperature/humidity, smoke/CO alarms, door locks, thermostats, window coverings, fans/air purifiers, robot vacuums, air quality sensors, and light sensors. Most of that core appears on Apple's official Matter accessory list, Google's supported device list and SmartThings' official Matter device list; Apple's list leaves out smoke/CO alarms, which work on Apple Home in tests.

Only six of those can start automations on all five platforms: buttons, contact sensors, motion/occupancy, temperature/humidity, smoke/CO alarms, and door locks. Only contact sensors and motion sensors are High-confidence on all five. That means a basic Matter home of lights, plugs, contact, motion and temperature sensors, locks and a thermostat is workable on any of the five, but automation depth and evidence quality still vary.

Automations are where the platforms really differ

Pairing counts are close at the top, but automation-start counts are not: Home Assistant 24, SmartThings 23, Google Home 17, Apple Home 14, Alexa 6. Alexa's gap is mostly Unknown ratings rather than confirmed No values. Unknown means MatterCheck could not confirm either way, not that a feature definitely fails. For example, for on/off lights and plugs, owner reports from 2023-2024 conflict: one owner saw Tapo P125M Matter plugs offered as routine triggers, another saw Eve Energy and Tapo Matter outlets missing. Amazon's Matter categories page maps these types only for control, so the rating stays Unknown.

Apple Home has Unknown thermostat and fan/air purifier triggers, and a robot vacuum's state can't start an Apple Home automation at all. Google Home counts air quality and light sensors as Partial because those starters only exist in the Script Editor, not the standard app automation editor, as shown in Google's Script Editor example scripts. Home Assistant and SmartThings are much more permissive on triggers, which is where they pull ahead of Apple Home, Google Home and Alexa.

Locks, thermostats, robot vacuums and leak sensors

These four types show why a single support number never tells the whole story.

• Door locks: Apple Home, SmartThings, and Home Assistant are Yes on all four fields with High confidence. Google Home control and automation action are Partial: voice unlock is disabled and remote unlock needs a PIN. Alexa routine lock actions work, but unlock is restricted, so its action is Partial.
• Thermostats: Everything pairs and works as an automation action everywhere, but only Home Assistant is High. Apple Home and Alexa thermostat triggers are Unknown. SmartThings is rated Yes, but its only independent native test from 2025-06-26 on a Honeywell X2S saw setpoint changes and automations fail, so that Yes rests on Samsung's official Matter device list rather than a positive test.
• Robot vacuums: Google Home, SmartThings, and Home Assistant are High with Yes on all four fields. Apple Home can run a vacuum from automations and scenes, but the vacuum's state cannot start an Apple Home automation. Apple's iOS 18.4 release notes added Matter robot vacuum control, scenes and automations, and a 2026-03-18 The Verge test ran a Matic vacuum from Apple Home; the No for the trigger rests on developer statements, so it's Med.
• Leak sensors: SmartThings and Home Assistant are High. Apple Home is Med because Apple's official Matter accessory list doesn't name leak sensors, though a 2026-01-31 HomeKit News test of the IKEA KLIPPBOK shows it working. Google Home is Med because Google's developer device list omits water leak detectors and the trigger evidence is Google Home Help's Leak/No Leak starters (added 2026-02-02) plus owner reports. Alexa is Partial on pairing, has no control, and its trigger is Unknown; a 2026-03-16 PCMag test of a Shelly Flood Gen4 saw a water-detected routine work, but the maker's cloud account was also set up, so the native Matter path isn't isolated.

Newer and niche Matter device types

Appliances, energy meters, pumps, water valves, speakers, water heaters, and pressure sensors are where platform counts diverge most. SmartThings and Home Assistant pair all of them, but almost every one of those rows is Med because the evidence is official listings, code or docs rather than dated hands-on tests, and few products of these types ship. Home Assistant is an exception on energy meters: it is High because plugs with built-in meters provide dated hands-on evidence.

Google Home pairs pumps, speakers, pressure sensors, and energy meters, but no consumer Matter pump is sold, and the only products we found implementing the Matter Speaker type are Philips TVs, and the one report of a Matter speaker in use came through a Matter bridge. Google's Matter clusters documentation shows speaker support is volume and on/off only, not media playback. Energy meters and pressure sensors pair in Google Home, but neither can start an automation, and Google lists no controls for an energy meter. SmartThings added energy meters in Samsung's 2026-10-06 Matter 1.6 announcement; control is Partial because a meter is read-only, the trigger is Partial because only meters built into plugs have been shown starting routines, and the hub firmware is still rolling out (2026-10-15 to 10-20).

Which hub or controller each platform needs

Hub requirements are separate from device-type support, and Wi-Fi and Ethernet Matter devices don't need a Thread border router; Thread devices do.

• Apple Home: With iOS 18+, an iPhone can add and control Matter accessories without a home hub. iPhone 15 Pro and later can also control Thread accessories without one. Otherwise Thread accessories need a Thread-enabled home hub such as an Apple TV 4K, HomePod (2nd gen), or HomePod mini. Apple still recommends a home hub "for the best experience", as noted in Apple's Matter accessory list.
• Google Home: Google requires a Matter-enabled hub before you can add Matter devices. Wi-Fi-only options include Nest Audio, Nest Mini, and Nest Hub (1st gen). Thread border router hubs include Google Home Speaker (2026), Nest Hub (2nd gen), Nest Hub Max, Nest Wifi Pro (6E) and Google TV Streamer (4K). IPv6 must be enabled on the network. See Google Nest help for Matter hubs and Thread border routers.
• Amazon Alexa: Matter devices connect through a Matter-supported Echo or eero, with no separate vendor hub. Only some Echo and eero models are Thread border routers, including Echo (4th Gen), Echo Hub and several eero routers on Amazon's Matter support list.
• SmartThings: You need a SmartThings Matter controller hub. Samsung lists the SmartThings 2018 Hub (v3) and Aeotec Smart Home Hub as controllers with Thread. The 2015 Hub (v2) is Wi-Fi/LAN only and needs a third-party border router plus its Thread network key. Samsung announced Matter 1.6 support on 2026-10-06, with hub firmware 0.62.14 rolling out 2026-10-15 to 10-20, according to Samsung Newsroom. See SmartThings x Matter support for hub details; our SmartThings Matter guide goes row by row.
• Home Assistant: Home Assistant runs its own Matter controller through the Matter Server app, and Home Assistant OS is the only supported install. Thread devices need a border router near them, including Home Assistant with a Connect ZBT-1/ZBT-2/SkyConnect and the OpenThread Border Router app. The Home Assistant Matter integration docs cover the controller and Thread setup; our Home Assistant Matter guide goes row by row.

See Which hub or controller each Matter platform needs for the full hub list and general Thread notes.

You don't have to pick just one

Matter lets one device join Apple Home, Google Home, Alexa, SmartThings, and Home Assistant at the same time, as long as you have a hub or controller for each platform, as Google Home's multi-admin help explains. Changes sync: turn a light off in Google Home and the other apps show it as off. Home Assistant's Matter integration docs say the standard requires each device to support at least 5 fabrics, and SmartThings' support article says each device can connect to 5 services.

This is the practical fix for gaps like Alexa's Unknown triggers: pair the device to Alexa for voice and app control, then share it into Home Assistant or SmartThings and use their automation engine for the trigger. Do not reuse the printed QR/setup code for a second platform, as Amazon's sharing help warns. Make a new temporary pairing code in the app the device is already in, then add it elsewhere. Sharing gives every platform the same device, but not every platform supports every device type or feature. See Matter multi-admin and sharing a device across platforms.

How to choose

• If you want the widest device-type coverage and the most automation triggers: Home Assistant or SmartThings are the broadest in the matrix, but check the specific product before you buy because many rows are Med.
• If you are already on Apple devices and prioritize well-evidenced core types: Apple Home is strong on lights, plugs, buttons, contact/motion/temperature/air quality/light sensors, locks and blinds, with 15 High rows, but it lacks pumps, water valves, speakers, water heaters and pressure sensors, none of which appear in Apple's Works with Apple Home categories.
• If you use Google Home and want broad pairing plus native routines: Google Home covers most common types with 21 pairs and 17 starters, but some sensor triggers require the Script Editor, and water valves and water heaters are absent.
• If you just want common Matter devices working on Echo: Alexa pairs and controls lights, plugs, sensors, locks, thermostats, blinds, fans, and vacuums, but only a short list are confirmed routine starters, so do not rely on it for complex state triggers.
• If you need the long-tail types: Use Home Assistant or SmartThings first, because water valves and water heaters pair only on SmartThings and Home Assistant (both are on SmartThings' official Matter device list), and those two are the only platforms that pair all seven niche types, but every one of those niche rows on both is Med except Home Assistant energy meters. Leave room to return hardware if a specific device does not actually work.

How we checked

Values and confidence come straight from MatterCheck matrix v1.14, 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 that platform; a pairing-only test does not count. Unknown means we could not confirm either way, not that the feature does not work. See the methodology and device type pages for the current values and evidence behind each rating.
