This invention provides for communicating wirelessly with irrigation control valves. This can greatly simplify and lower costs for installation of new irrigation systems. It can also provide existing installations with an option to quickly add new irrigation stations without digging ground to lay pipe. A programmed watering schedule on an irrigation controller determines when the irrigation control valves open and close. A wireless controller transceiver unit obtains signals from the irrigation controller and transmits these signals wirelessly to a valve transceiver. The irrigation control valves open or close according to the signals received by the valve transceiver.
