Introduction
You can seamlessly connect SONOFF smart devices to Amazon Alexa using cloud-to-cloud integration via eWeLink, enabling hands-free control through Echo speakers and the Alexa app.
With this setup, you can switch lights, plugs, sensors, and more via simple voice commands or smart routines—all without needing a separate hub or Matter support.
This article will guide you through the setup process, supported devices, and how to use Alexa to control your SONOFF smart devices.
