What you need for Amazon Alexa

  • Alexa: Matter-compatible Echo devices handle Wi-Fi Matter devices (Amazon’s developer documentation, checked October 1, 2026); Amazon says they support “a subset of Matter 1.5 and lower device types”.
  • Amazon says Alexa supports “a subset of Matter 1.5 and lower device types”, and publishes no list of supported Matter device types that we have on file, so this page counts a model for Alexa only when its record lists Alexa (5 of 8 are also named by the maker).
  • Matter is not tied to one platform. The CSA says: “Multi-admin is one of the core features that allows users to connect their Matter devices to multiple platforms, apps, or other control points, so they can control them where and how they choose.” And platforms add support at different times: “All Matter-certified smart home platforms and apps update to support different Matter-enabled device types and categories at different times.”

How we count

A product is on this list when it has a CSA Matter certificate matched to the exact model, is sold in the US with a verified store link, and its catalog record lists Amazon Alexa. A platform a record lists is a catalog statement; the “Maker’s page names” column shows the stronger one, a quote from the maker’s own page. Two records that share one store listing count once, and models we have retired from our picks are left out. A list is indexed by search engines only with at least 5 such products. Editorial policy.

Frequently asked questions

Which Matter thermostats work with Amazon Alexa?

As of October 24, 2026, 8 CSA-certified Matter thermostats sold in the US list Amazon Alexa in their catalog records; 5 of them are named for Alexa on the maker’s own page, and the table marks them. Brands with the most models: Google (2), Boldr (1), Laticrete (1), Meross (1), Resideo (1) and 2 more brands. A certificate does not promise every feature on every platform, so check the maker’s page for the exact model.

Do I need a hub or a Thread border router for Matter thermostats on Amazon Alexa?

8 use Wi-Fi, so they need no Thread border router. Alexa: Matter-compatible Echo devices handle Wi-Fi Matter devices (Amazon’s developer documentation, checked October 1, 2026); Amazon says they support “a subset of Matter 1.5 and lower device types”.

Does Amazon Alexa support Matter thermostats?

Amazon says Alexa supports “a subset of Matter 1.5 and lower device types”, and publishes no list of supported Matter device types that we have on file, so this page counts a model for Alexa only when its record lists Alexa (5 of 8 are also named by the maker).

Why does this page list 8 and not every certified Matter thermostat?

A model is counted here only when its catalog record lists Amazon Alexa. MatterCatalog lists 14 CSA-certified thermostats sold in the US in all, so 6 do not list Amazon Alexa. They may still work as Matter devices: “All Matter-certified smart home platforms and apps update to support different Matter-enabled device types and categories at different times.” See the full list at All Matter thermostats.
