The RainMachine sprinkler controller automatically adjusts your watering amount by lowering it on rainy or colder days and increasing it on hot summer days. The system not only saves water but it also protects your plants. The versatility of each program is unprecedented: select individual weekdays, Even/Odd day mode, Cycle and Soak, or Station Delay. Run the programs one-at-a-time, sequentially or even in parallel! The RainMachine Wi-Fi sprinkler timer is designed to handle possible conflicts, like simultaneous commands to the same valve or overlapping schedules.
