Avatto WSM20DC Smart Switch Module

The Avatto WSM20DC smart switch module is a miniature potential-free relay designed to modernize traditional electrical installations by enabling smart home functionality within existing infrastructure. Its compact form factor allows installation inside standard flush-mounted boxes and switchboards, making it suitable for both new builds and retrofit applications without requiring structural changes.

The module utilizes Wi-Fi 6 technology to ensure fast, stable, and low-interference communication, even in environments with many connected smart devices. Through integration with the Tuya and Smart Life platforms, users can control connected systems remotely via smartphone. Compatibility with Amazon Alexa and Google Home further enables voice-based operation and seamless integration into broader smart home ecosystems.

Advanced automation capabilities allow precise scheduling and control of connected devices. Users can configure timers, recurring schedules, countdown functions, random activation modes, and cyclic switching patterns. These functions make it suitable for a wide range of applications, including lighting systems, garage doors, heating equipment, water valves, and boilers, all of which require potential-free switching.

The mobile application provides full visibility of device status and event history, enabling users to monitor usage patterns and respond to changes in real time. The Relay Status function allows customization of behavior after a power outage, with options to restore the previous state, remain off, or turn on automatically, improving both safety and predictability.

The module also supports multiple external switch types, ensuring compatibility with existing wiring configurations and improving installation flexibility. Combining compact design, stable wireless performance, and advanced automation features, the Avatto WSM20DC offers a practical solution for expanding smart control across a wide range of electrical systems.
