 Unplug the 3V3 VCC cable to be able to watch the serial monitor when the Sonoff is powered on through main **else you will fry the esp**. You can also flash Sonoff's esp like this (**be careful to not touch main current through the Sonoff** when manipulating it). \\
 It also looks like when the program is of a given size, the USB/serial adapter (CH340G at least) is not able to give enough current for the esp to run properly (crashes in loop with stacktraces). An FTDI adapter looks more reliable.\\
 You can also use ''screen /dev/ttyUSB0 115200'' to watch the serial monitor, but Arduino IDE serial monitor is more practical to use as it is relaunched each time it detects when the USB/serial adapter is plugged to a running chip.
+Using a FTDI as below is more practical as it's able to properly power the Sonoff S20. **Don't forget to set the jumper to 3.3V or you will fry the ESP**.
