Thanks for your reply.
Sorry I was using 'Serial.print' just to show what it was doing.
What I want is to have (4, 1) sent to mySwitch.switchOff.
I need to keep Ch and Sk as there original value and send then to - mySwitch.switchOff(Ch, Sk); ''mySwitch.switchOff(4, 1);''
I am using #include <RCSwitch.h> 'GitHub - sui77/rc-switch: Arduino lib to operate 433/315Mhz devices like power outlet sockets.'
