Recording and processing utility commodity usage

This describes a smart device, like an irrigation controller, that sits at a user's property. It gathers information such as water flow, pressure, and weather data, stores it, and then calculates how much water should be used for irrigation. This usage information is then sent over a network to the user or other parties to help them manage their watering systems.

Why it matters: Filed before ubiquitous internet and low-cost IoT hardware. The claims describe a networked irrigation controller, which is now feasible with off-the-shelf sensors, embedded processors, and cloud services.
