Basic 1 ... how to check if a sensed value is greater than ...

This simple flow checks whether the Input1 value is greater then 10. If yes it prints out the value alto, otherwise the value basso. 

Notice that since msg.payload is a string it must be parsed into an Integer to check if the condition holds.

if (parseInt(msg.payload)>10){
    msg.payload="alto";
}
else{
    msg.payload="basso";
}
return msg;
