Do Matter over Thread switches and dimmers need a hub?

Yes: a Thread border router, as well as your platform’s Matter controller.

Google says Thread devices need a hub that also works as a Thread border router. Matter-compatible Echo devices handle Wi-Fi devices; a Thread device needs an Echo that is also a Thread border router, which Amazon’s developer documentation names as the Echo (4th Gen), Echo Hub, Echo Show 10 (3rd Gen), Echo Show 15 (2nd Gen) and Echo Show 21 (checked October 1, 2026).
