Could we use your shutdown controller with the Opus as a in-line shutdown on the 5v line? Say you don't use your car for a 24 hour period, could you then shut it off at the 5v to preven further drain? What other problems might that cause? The computer would have to just do a reboot once turned on, correct? I've read a bit about your controller but I don't remember the time limits...Could that be possible?
