Abstract: An irrigation management system reduces high peak water use values by utilizing a microprocessor disposed in an irrigation controller to (a) receive peak water use information from a source other than a water supplier (b) receive water use information at a consumer site, and (c) automatically derive a new irrigation schedule that is at least partly based on the information received. The new irrigation schedule preferably includes at least one of a modification in a default irrigation frequency or start time, a reduction in a default irrigation application duration, the use of a rolling-average in the determination of the new irrigation application duration and other changes or modifications to the default irrigation schedule that will provide for the reduction in high peak water use values. Additionally, the microprocessor will display to the water user and/or third parties details on the new irrigation schedule and information received from the water supplier.

Abstract: An irrigation controller is programmed to automatically initiate communication with a data server to perform at least one of the following functions: (a) exchange irrigation data; (b) receive control data; and (c) receive synchronization data. The irrigation data can be station runtime history, evapotranspiration (ETo) data, rainfall, weather related information, irrigation faults and any other irrigation data. The control data can involve station runtime settings, cycle and soak settings, irrigation scheduling and any other irrigation control data. The synchronization data preferably includes a date and a time, originating from the data server, but can include other data that would be used to synchronize the communication between the irrigation controller and the data server. In a preferred embodiment of the present invention a microprocessor disposed in the irrigation controller is programmed to use the date and time to schedule a future contact with the data server.

Abstract: The present invention provides systems and methods in which a microprocessor (220) is programmed to calculate an accumulated watering need for an irrigation zone of station (400)and control irrigation to the zone or station (400) using an automatically varied cycle amount that falls between a user controllable maximum threshold and a user controllable minimum threshold. The cycle amount is preferably at least partly derived from ETo data. The minimum threshold may vary during a period of 12 consecutive months, may vary as a function of time of year, as a function of crop maturity or as a function of any other suitable factor where it would be advantageous to set a minimum threshold. The cycle amount may equal the accumulated ETo value(s) or may equal the maximum threshold value. Furthermore, the microprocessor (220) may be programmed to control the irrigation to the zone or station (400) using an automatically varied day schedule.

Abstract: An irrigation controller has run-times that are modified as a function of a calculated volumetric irrigation amount and a preferred irrigation amount. The preferred irrigation amount is at least partly based on an evapotranspiration (ETo) value and the area of the irrigated site. The calculated volumetric irrigation amount is based on flow meter data and inputted irrigation run-times. Preferably the flow meter is a water meter that measures water distributed to the irrigation system and to other water using devices at the irrigated site, and the flow data is based on signature data. In addition to flow data, water pressure may be measured that corresponds with the flow data. It is anticipated that the function will involve the dividing of the preferred irrigation amount by the calculated volumetric irrigation amount to arrive at a modifying factor.

Abstract: An irrigation controller modifies sophisticated irrigation protocols using an extremely simple user control. In one aspect of a particularly preferred class of embodiments, the user control includes a simple “more/less” (increase/decrease) adjustment. In another aspect of preferred embodiments, the controller automatically determines appropriate irrigation amounts, start times, durations, and frequencies. Such automatic determination may advantageously be based in part on the more/less adjustment.

Abstract: A method is provided for identifying a flow anomaly in a system having first and second water using devices, comprising: generating baseline data comprising water use signatures and corresponding water pressure information regarding the water using devices; comparing the baseline data with actual water usage signatures and corresponding actual water pressure information to identify a flow anomaly with the water using devices; and providing information on the flow anomaly to an individual. It is especially contemplated that baseline data are generated for multiple devices coupled to a common water supply system, with baseline data from two or more water using devices compared against future water use patterns of the same devices. Apparatus to accomplish these tasks is preferably housed in an irrigation controller, which may be advantageously coupled to a flow meter.

The irrigation schedule may be at least partly derived from ETo data and may be from current ETo data, estimated ETo data or historical ETo data. The condition may be plant establishment, plant maturity or plant health.

Abstract: The present invention provides systems and methods in which an irrigation controller uses a regression model to estimate an evapotranspiration rate (estimated ETo), and uses the estimated ETo to affect an irrigation schedule executed by the controller. The regression model is preferably based upon a comparison of historical ETo values against corresponding historical environmental values, with the data advantageously spanning a time period of at least one month, and more preferably at least two months. Data for multiple environmental factors may also be used. The environmental factor(s) utilized may advantageously comprise one or more of temperature, solar radiation, wind speed, humidity, barometric pressure, and soil moisture. Values relating the environmental factor(s) may enter the controller from a local sensor, a distal signal source, or both.
