Sonoff WiFi Smart Switch Basic R4 10A

Upgrade your smart home ecosystem with the Sonoff WiFi Smart Switch Basic R4 10A. Powered by an upgraded ESP32 chip, the BASICR4 elevates the performance and reliability of traditional relay switches while retaining an accessible, compact form factor. Designed for effortless DIY installation behind appliances or lighting circuits, it transforms standard electronics into fully automated smart devices.

Innovative Control with Magic Switch Mode

Unlike conventional smart relays, the Sonoff Basic R4 features the revolutionary Magic Switch Mode. This capability ensures your light remains reachable and controllable via the mobile app even after someone toggles a traditional double-pole wall switch off. Say goodbye to offline smart lights caused by manual switching.

eWeLink-Remote Gateway & Two-Way Control

The BASICR4 doubles as an eWeLink-Remote gateway. Pair it wirelessly with auxiliary remotes like the Sonoff S-Mate2 or R5 scene controllers to achieve convenient two-way multi-location switching and robust local control without complex rewiring.

Enhanced Safety & Overheating Protection

Safety is paramount in electrical installations. The BASICR4 includes a built-in real-time temperature sensor that detects overheating conditions and proactively shuts down the device to prevent deformation, casing damage, or electrical hazards. It is certified by CE, FCC, and authoritative ETL standards for total peace of mind.
