Configuration of the Sprinklers Pi module is done in the Settings screen. Settings can be accessed from the home page through the gear icon in the upper right corner.

NOTE: If this is your first execution, the system will startup bound to port 8080. To browse to the home page, simply type the following as the URL into any browser on the local network (assumes the raspberrypi machine name is 'raspberrypi1'):
raspberrypi1:8080

Before configuring a new system, you should check the Raspberry Pi's Time Zone

A screenshot of the settings screen is below: Settings Screen

The first five settings on this screen have to do with setting up Weather Underground as your weather provider. Doing so will allow you to automatically and optionally adjust duration settings on a schedule based on the temperature, humidity, and rain. (e.g. a hot dry day will result in a longer duration, a cool damp or rainy day will result in a shorter duration).

For more details on the Weather Underground Settings go to Weather Adjustments

Web Port configures the port that the web page is available on. Set to 80 to make the Sprinklers Pi bind to the normal web page port. The default is port 8080.

Seasonal Adjust will adjust the durations of all schedules based on the percentage selected. The default is obviously 100%. Setting this to 50% will make all schedules run at 1/2 their configured values. Setting this to 200% will make all schedules run twice as long as their configured values (not to exceed 254 minutes). This adjustment is in addition to any weather based adjustment.

Output selects the type of physical output that the sprinklers pi will use to turn on and off zones. The default is 'NONE' which runs in a simulation mode.

  • 'Direct Positive' assumes there are relays or triacs associated with physical GPIO bits on the Raspberry Pi. The actual GPIO lines associated with each zone are 0 (pump), 1 (Zone 1), 2 (Zone 2) .... 15 (Zone 15). A chart detailing which GPIO line is associated with which pin on the Raspberry Pi headers is here: http://wiringpi.com/pins/
  • 'Direct negative' uses the same pins as GPIO, but assumes a logical low turns on the outputs. In other words, all zones that are "off" will be turned on, while any on zone will be turned off.
  • 'Sprinklers Pi' assumes the system is configured with the fantastic OpenSprinkler Pi module from rayshobby.net. Up to 1 expansion board can be added.
