Sonoff Basic R4

This switch connects directly to 2.4GHz Wi-Fi, allowing users to turn devices on/off remotely, set schedules, and create smart scenes. It supports multi-control setups, including rocker switches, push buttons, and detached switch mode, making it adaptable to various wiring configurations. The R4 introduces Magic Switch Mode, which allows control of lights even when a traditional wall switch is turned off—ideal for retrofitting older homes. It also includes auxiliary overheating protection and TVS surge protection, ensuring safe operation in harsh electrical environments. The device is Matter-ready, meaning future firmware updates may allow integration with Apple Home, Google Home, and other Matter-compatible platforms.
