ABSTRACT:
An irrigation scheduler modifies output of a preprogrammed irrigation schedule of an installed irrigation controller to at least partially improve irrigation of the corresponding landscape. Preferred embodiments accomplish this task using a microprocessor programmed to: (a) derive a first set of information from the output of an irrigation controller used to control an operation of an irrigation valve; (b) receive a second set of information comprising at least one of an environmental factor and a meteorological factor; and (c) use the first set of information and the second set of information to interfere with reception of the output by the valve.
