Yamaha R-N301 control and PA System automation

[gtsamis]

Nice example, one small improvement: you can use captures inside of regexps like this:

Code:

power=string.sub(string.match(response_body,"<Power>%a+</Power>"), 8, -9)

power=string.match(response_body,"<Power>(%a+)</Power>")

Both lines do exactly the same thing, but you don't have to count characters when using captures

  You are right, didn't cross my mind to use string.match because the reply is pretty much static but will be helpfull on futher control.

Thank you
