Any Harmony remote can be used to control the PS3 if:
(1) buy the
PS3 adapter
(2) buy the
Nyko gaming remote and just use the usb adapter.
(1) allows you to turn on/off using the harmony. (2) does not turn on PS3 but controls everything else.
btw, I thoroughly recommend getting any harmony remotes... i have 3 of them! (basement, living room, bedroom)
