Methods and systems for irrigation control

A system for controlling irrigation control systems at a plurality of agricultural or landscape sites, comprising:

• at least one wireless node at each of the plurality of sites;
• and
• a server computer system located remotely from the plurality of sites, said server computer system communicationally coupled to each of the at least one wireless node over a communications network for receiving data from and controlling operation of the at least one wireless node at each of the plurality of sites, said server computer system also selectively coupled to a plurality of devices each operated by one of a plurality of end-users over a communications network for transmitting the data to and receiving remote control commands or queries from the plurality of end-users;
• wherein the data transmitted to a given end-user corresponds to the site for which the given end-user has authorization;
• at least one gateway, at a location of each of the plurality of sites, for transferring the data between the at least one wireless node and the server computer system;
• wherein the server computer system transfers an irrigation schedule to the at least one wireless node of each of the plurality of sites for storage and execution at each of the plurality of sites;
• wherein the at least one wireless node at each of the plurality of sites is configured to compare received sensor measurements against at least one user-entered control condition, and control the irrigation accordingly, wherein the at least one user-entered control condition is defined at the server computer system by the end-user using a respective device and is transferred from the server computer system to the at least one wireless node and stored in an internal memory of the at least one wireless node;
• wherein the server computer system determines a new irrigation schedule or a schedule adjustment for a given site based at least on weather data and does not automatically implement the new irrigation schedule or schedule adjustment, rather the server computer system provides the new irrigation or the schedule adjustment as a recommended change;
• wherein the given end-user is provided an option do one or more of accept the recommended change, reject the recommended change, ignore the recommended change, and manually input a new irrigation schedule or manually input schedule adjustments.
