I just installed on my Sonoff S20 socket, the PCB is labelled "S20_EU_V1.3 2017-2-16". It seems to have flashed ok from the Arduino IDE, but when I plug it in nothing happens. The LED does not light up at all, the button does nothing, and it does not connect to Wifi. I filled all the info int the h file correctly.
