Sonoff ESP32 WiFi Smart Switch

Already flashed with the latest Tasmota firmware, either with the standard template or a specially adapted one for Magic Switch Mode. (For more information see "Magic Switch Mode")

The Sonoff Smart Switch BASICR4 Wi-Fi Smart Switch is a modern device that helps you control your smart home. Equipped with an advanced ESP32 chip, the BASICR4 combines advanced functionality and increased performance at a reasonable price. It is the perfect solution for anyone who wants to feel more comfortable in their own home, be it by controlling lighting, an electric kettle, a humidifier, garage doors or heaters.

Advanced ESP32 chip technology - The ESP32 chip in the BASICR4 is the heart of this smart switch. Thanks to the latest technology, the device offers expanded basic functions and increased efficiency, which also makes it economical. Its advanced architecture ensures smooth and reliable operation, which is crucial for any smart home device.

Magic Switch Mode - Limitless control The Magic Switch Mode in BASICR4 allows you to control the light switch via the app, even after the traditional wall switch has been turned off. This feature provides flexibility and convenience by allowing you to control lighting from anywhere, regardless of physical switch Settings.

Remote control with “eWeLink-Remote”* - The BASICR4 has “eWeLink-Remote” gateway functionality, which enables remote control and the creation of smart scenes via the app. This feature offers two-way control and local management, giving you full control over your home devices. *cannot be used with Tasmota firmware

Security and Reliability - Security is of utmost importance with any smart device. The BASICR4 is equipped with a built-in temperature sensor that detects the maximum temperature of the product in real time, preventing deformation, melting, fires or high temperature exposure.

Magic Switch Mode

Description:

The Sonoff BASICR4 contains a zero-cross detection circuit connected to GPIO5. During normal operation, a pulse of approximately 650 µs length with a frequency of 100 Hz (every 10 ms) is generated on GPIO5 at every zero crossing approximately every 10 ms. Although this could be used to trigger power switching at zero crossings to extend the life of the relay, it is presented by Sonoff as a MagicSwitch to toggle the relay during power "glitches" that utilize this special wiring

The Sonoff BASIC4 can therefore be easily integrated into existing 2-way cabling without having to lay new cables.

The Smart Switch can be installed directly on the light source and remains controllable even when the wall switch is turned off.

To activate the MagicSwitch function as advertised by Sonoff, you can order this variant directly with the appropriate template or customize the template yourself by Setting GPIO5 as MagicSwitch with index 1. Use the following template for this:

{"NAME":"Sonoff Basic Magic Switch","GPIO":[0,0,0,0,224,10560,544,0,0.32,0,0,0,0,0,0,0,0,0,0,0,0],"FLAG":0,"BASE":1}

This function depends on the switch used being able to produce a sufficiently large (but not too large) voltage dip during switching. Remember that this is triggered by voltage drops in the power grid. If your power grid has "natural" voltage dips, false tripping could occur. By Setting MagicSwitchPulse to the highest value that will still work with your switch, the smallest power surges could be filtered. But if your power grid ever experiences voltage dips in the same range as the switching time of your switch, this function may be useless.

Debug and adjustments:

By Setting the log level to 3 (weblog 3), a log message will indicate the length of the measured pulse and confirm the length of the mask window (in 50 ms units):

Example: 17:11:43.993 MSW: length:18464, window:5

You can adjust the minimum length for triggering the MagicSwitch using the MagicSwitchPulse command, with a value between 1000 µs and 500000 µs. It is not advisable to Set values ​​below 1000 µs as this may result in self-tripping by the zero crossing detection pulse. Values ​​above 500,000 µs make no sense, as the BasicR4 will probably restart in the event of such disruptions.

The value is NOT saved permanently. You can enable it permanently by using a boot rule such as:

Rule1 ON power1#boot DO MagicSwitchPulse 5000 ENDON
