Remote socket (int Help)

As we can't see the definition of mySwitch.switchOff(), it's impossible to tell whether that is right or not.

This

Serial.println(Ch, Sk);

is saying print Ch, using the number base Sk. If you wanted to end up with, say, '4, 1', then you would do

Serial.print(Ch);
Serial.print(", ");
Serial.println(Sk);
