Java based irrigation controller that ties in weather station data to make intelligent decisions on whether or not to water your garden.

Features

Multiple controller support (at the same time)

Multiple weather station support (at the same time)

Custom scheduling times

Interactive shell to provide real-time control and information

Weather threshold suppression including:

• x # days to look ahead for chance of rain
• x # days to look back for previous rain
• wind speed
• max/min temperatures

Extreme temperature irrigation multiplier:

- Temperature to trigger at - X # of days to look ahead for trigger - Amount to multiply irrigation by if triggered

Currently supporting the following controllers:

EtherRain8 - http://www.quicksmart.com/qs_etherrain.html

Currently supporting the following weather stations:

WeatherUnderground Personal Weather Station (PWS) - http://www.wunderground.com/weather/api/
