Can you think of any reason why simply measuring consumed current and making sure it matches an expected pattern (I.E. toggling between all-on and "blink") with the correct frequency and during the right time of day wouldn't work with any of the systems you've put in?
Of course with a contact or two input as an additional input to catch the failures the controller knows about?
