Not sure if control4 uses ECP or not I wanted to have an automated reboot too:
Secret menu method is disabled through ECP, here it is just for documentation:
Press Home five times, Up once, RW twice, FF twice
i was able to get it to work via ECP by simulating the key presses required to navigate the menu but method is very particular to Roku model and OS you have and could be disastrous if lands you on the reset to factory defaults page instead!
