How many custom programs do you need? One for everything? How about a different program for each day or each zone? With OpenSprinkler you can create a wide array of independent programs with custom start times to fit your need. You can visualize programs using the preview feature, and check station runs through graphical plots of the logging data.Use a master zone or pump; run zones in sequence or parallel; easily expand the number of zones; give each zone and each program a custom name -- these are all supported by OpenSprinkler. Attach a rain sensor, or manually set rain delay time. Take it one step further and use our automatic weather-driven algorithms: your sprinkler water times are constantly adjusted based on your local weather and rainfall conditions. No proprietary weather data -- we use data that's publicly available around the world.
