The Avatto Zigbee Switch Module-L is a compact smart relay designed to be installed behind your existing wall switches, allowing you to modernize your home lighting without replacing the physical hardware. Operating on the Zigbee 3.0 protocol, this 3-gang module requires a compatible gateway to enable remote management through the Tuya or Smart Life apps, as well as voice control via Amazon Alexa and Google Assistant. It is specifically engineered for installations where a neutral wire is unavailable, simplifying the upgrade process in older electrical systems. This 3-channel variant is capable of managing three separate loads of 10-100W each, providing versatile control for multiple lighting circuits. The device supports 2-way control and includes a power failure memory function, ensuring your lights return to their previous state after an outage. With its CE certification and support for schedules and timers, it provides a reliable way for you to automate your daily routines while keeping the familiar look of your current interior design.
