I wish we had a small box like the HF-AUTO-R to control the amp features...
as there is no official support on this and the TRX manager software is rather difficult,
after the warranty period is over, I have the following idea to try.use a solenoid push type actuator to push a stylus pen which can toggle between standby and operate mode.
of course the solenoid push force has to be gentle enough not to damage the touch screen and some sort of mounting is needed to properly align it to the OPR/STBY portion of the screen.?
see this for the solenoid linear action...
