The Sonoff Basic R4 is part of the well-known Basic series of Wi-Fi switches from Sonoff, designed to control electrical devices such as lights, fans, and other appliances. This smart switch integrates app control, voice control, timers, and Magic Switch mode, making it a versatile addition to any smart home.

Magic Switch Mode

With its "Magic Switch Mode," the Sonoff Basic R4 can still be controlled via the app, even when a traditional wall switch is turned off. This is particularly useful in homes with conventional double-pole toggle switches and is a brand new feature for the Sonoff Basic family.

Control

The Sonoff Basic R4 can be remotely controlled via the eWeLink app, which is available for both Android and iOS. This makes it easy to control your lights and other devices, no matter where you are.

This smart switch can be integrated with other smart home systems such as Amazon Alexa and Google Home, providing even more options for voice control and automation.

The Sonoff Basic R4 acts as an intelligent switch with the gateway function "eWeLink-Remote". This allows you to add secondary devices and create two-way control and local control.

Connection and Automation

The Sonoff Basic R4 supports the creation of smart scenes. For example, it can automatically turn on a fan when the room temperature exceeds a certain level, or turn on the light when motion is detected.

This smart switch is compatible with Home Assistant, eWelink Web Control, and IFTTT (only with an eWelink subscription), offering more options for customization and automation.

New Chip

With an upgraded ESP32 chip, the basic function and performance are improved, while keeping the price reasonable.

Safe and Reliable

With a built-in temperature sensor, the Sonoff Basic R4 can monitor and control the product's maximum temperature in real-time, preventing overheating and potential safety risks.

The Sonoff Basic R4 has achieved certifications such as CE, FCC, ETL, etc., underscoring the product's safety and reliability.
