Now to your issue: The command to change inputs is xxFN
FNxx is the feedback event from the receiver... It is a bit confusing indeed.
So just try 02FN
LM is for "listening mode"
And yes, I will do further development!
I don't know if there is possibility to directly select an internet radio preset..
But if you can call these presets via your remote you can also call them via network.. Maybe not direcly, but since you're using eventghost you can make macros for that.
