Which device types can Alexa control over Matter in 2026?
Alexa supports 24 Matter device types across seven categories, according to Amazon's developer documentation last updated 8 April 2026: dishwasher and room air conditioner; door lock and window covering; air purifier, fan and thermostat; seven lighting and plug types; robotic vacuum cleaner; eight sensor types including smoke-CO alarm and water leak detector; and generic switch. Matter-compatible Echo devices implement a subset of Matter 1.5.

The full list, as Amazon publishes it
Amazon groups its supported Matter device types into seven categories. This is the list verbatim from the developer documentation, last updated 8 April 2026.
| Category | Device types |
|---|---|
| Appliances | Dishwasher · Room air conditioner |
| Closure | Door lock · Window Covering (exterior and interior blinds) |
| Heating, Ventilation, and Air Conditioning | Air purifier · Fan · Thermostat |
| Lighting, Smart Plugs, and Outlets | On/Off light or plug · Dimmable plug · Dimmable light · Lamp · Light bulb with enhanced color control · Light strip · Power strip |
| Robotics | Robotic vacuum cleaner |
| Sensors | Air quality sensor · Contact sensor · Humidity sensor · Light sensor · Motion detector · Smoke CO alarm · Temperature sensor · Water leak detector |
| Switches and Controls | Generic switch (button) |
Twenty-four device types in total. A Matter device whose type is not on this list will either not be added by Alexa at all or will be added with reduced function, regardless of whether it is Matter certified.
What is on the standard but not on Alexa's list
Matter defines considerably more than Alexa exposes. Three gaps are worth knowing before buying:
- Cameras. Matter 1.5, announced 20 November 2025, added camera device types with WebRTC video and audio. Cameras do not appear in Amazon's category list.
- Laundry washers. Not listed by Amazon. Google Home does list Laundry Washer among its supported device types, so this is a per-platform gap rather than a gap in the standard.
- EV charging and energy tariff devices. Matter 1.5 added an electrical energy tariff device type and EV charging enhancements. Neither appears in Amazon's list.
The documented restriction on locks
Amazon's page carries one explicit prohibition rather than a capability statement: "Amazon prohibits the use of SceneController and Alexa.RangeController with semantics in home security devices, such as door locks." A door lock is supported, but it cannot be driven through those two interfaces.
Why the category list is not the whole answer
Device-type support answers whether Alexa will add the device. It does not answer which of the device's features survive. Amazon's page pairs each category with the specific Matter clusters required and the Alexa capabilities they map to — a device can be a supported type while still exposing fewer attributes through Alexa than through its own app. See whether the manufacturer's app is still needed for how that plays out across platforms.
Related questions
Can Alexa show a Matter camera?
No. Cameras are absent from Amazon's supported Matter device categories list as of 2026-04-08, even though camera device types were added to the standard in Matter 1.5 on 2025-11-20.
Which Matter specification version does Alexa implement?
Amazon's documentation references the Matter Device Library Specification version 1.5 and Matter Application Clusters version 1.5, and states that Matter-compatible Echo devices support the Matter 1.5 SDK, enabling a subset of Matter 1.5 and lower device types.
