A properly programmed smart controller requires initial site specific set-up and will make irrigation schedule adjustments, including run times and required cycles, throughout the irrigation season without human intervention.
Controllers using weather-data from on-site sensors (qualifying models)
If the weather-based smart controller uses on-site weather data instead of a remote weather service, the on-site sensor must have the following (at a minimum):
- Solar radiation and/or temperature sensors
- Rain shut-off device (rain sensor or tipping bucket)

Controllers using weather-data from a remote weather source (qualifying models)
Weather-based smart controllers use weather data from remote weather stations via radio, pager or Internet signals. A rain shut-off device (rain sensor or tipping bucket) should be used in conjunction with the remote weather source.

Complete Replacement: An ET controller that replaces the existing controller, including the base unit, with a weather-based smart controller and corresponding components.
ET: Abbreviation for evapotranspiration, the measure of evaporation from the soil and transpiration from plants.
On-site: Refers to weather information gathered by sensors placed on the property and connected to the controller. The data may be conveyed through wires or radio frequency.
Rain shut off device: Device that prevents the controller from activating the valves when a preset amount of rain falls. Types of rain shut-off devices include rain sensors and tipping buckets.
Remote: Refers to weather information gathered by sensors at another location such as a regional weather station. The data may be conveyed to the controller through satellite, radio frequency, Internet or phone lines.
Retrofit/Add-on: Software or components which are attached to a compatible, existing irrigation controller. The software/components convert a standard controller into a weather-based ET controller.
Sensors: Any of several products that quantify weather conditions used by weather-based ET controllers. Sensors include: solar radiation, precipitation, wind and barometric pressure.
