Sonoff BASICR4 10A ESP32 Smart Switch — Wi-Fi Relay Module for Home Automation

Smart switch Sonoff BASICR4 10A ESP32 — Wi‑Fi relay module for home automation

Smart 1-channel switch for electrical appliances, supporting remote control over 2.4 GHz Wi-Fi; suitable for a wide range of household equipment. The SONOFF smart home system lets you control electrical devices remotely through the eWeLink app or by voice with Amazon Alexa or Google Home. You can create various scenes, group devices to switch several on or off with one touch, set timers and schedules, monitor the status of your home and devices in real time, and share control. Linking the eWeLink app with the IFTTT automation platform expands scene possibilities even further. SONOFF devices can also operate on the local LAN without a cloud server. Features: the smart switch is easy to install and control remotely from a smart device using the eWeLink app (Android, iOS); the relay signal is transmitted over a 2.4 GHz Wi-Fi network (5G is not supported). The BasicR4 version uses an ESP32 chip with Bluetooth support. A new "Magic Switch" mode lets you control the device through the app even when the wall switch is off. Paired with the Sonoff S-MATE switch, the BasicR4 can be controlled locally via the eWeLink-Remote signal at up to 50 m and can trigger other smart-scene devices (S-MATE sold separately). It is convenient for creating groups to control several devices at once and suits larger smart-home systems requiring scenes, schedules and timers. A further feature of this 4th-generation switch is supplementary overheating protection: a built-in temperature sensor detects and predicts the product's maximum temperature in real time, preventing deformation, melting, fire or overheating. CE, FCC and ETL certifications confirm its high safety and reliability standards.
