rti has a power toggle graphic that either shows if the system is on or off.
you can drop a power toggle command on top of it so when the client presses the power toggle it will send the command and the graphic will show the current status of the system.





so the sonance amp i am using has power toggle and discreet for each zone.
i can just drop a power toggle on these and the client knows if its on or off.

not so simple with onkyo receivers (2 of them) because 
they dont have a power toggle command in the system
so im going to have to make an if then macro on them.
