Description

Description

Capabilities

The Sonoff BASICR4 is the upgraded version of the classic smart WiFi switch, equipped with the advanced ESP32 processor. It offers faster response, improved connection stability, and increased processing power, while maintaining a low cost. It is designed to turn ordinary household devices and lighting into smart elements of your home, ensuring a reliable and modern automation experience.

Technology and Magic Switch Mode

The device introduces the Magic Switch Mode function, which allows you to control lighting fixtures through the app even when the traditional wall switch is turned off. In this way, remote access and automations remain always active. The use of the ESP32 chip ensures that the device operates with high performance, while also offering compatibility with the Matter ecosystem via a bridge for connection with Apple Home, Google Home, and Alexa.

Control and Advanced Security

The BASICR4 functions as an eWeLink-Remote gateway, allowing local two-way control using peripheral devices such as the S-Mate2 or R5, without necessarily requiring a WiFi connection for these commands. Special emphasis has been placed on safety, as it features a built-in temperature sensor that continuously monitors the device and automatically cuts off the power supply in case of overheating, preventing fire hazards or damage.

    Ok, they always do what they promise and for months now they have been working properly. Minus one star because many times the communication between the command you give through the nice app they have and the execution of the command is very slow. They have been installed on two desk lamps and often the command to turn the light on or off takes up to 30 seconds to be implemented. However, I am not entirely sure if the switch is to blame or if it has to do with the communication with the router.

    The evolution of the Basic R2, which I have been using without any problems for a long time. For those who also want control with a remote, so they are not dependent on the internet and the app, the R2 is the only way.

    Honest and of good quality but for use in specific cases due to its size. Behind a socket or in a ceiling light, for example, it doesn't fit at all. For a floor lamp, for instance, it is ideal.
    In the automated setting I personally have it in, it is reliable so far.
