Frequently Asked Questions – Smart Irrigation Controller
A smart irrigation controller uses local weather data, soil conditions, and flexible schedules to automatically adjust watering for each zone, instead of running fixed programs regardless of rain or temperature. This helps keep your lawn and garden healthier while reducing water waste over the long term.
Many smart irrigation controllers can still run previously saved schedules if your Wi‑Fi or internet connection is temporarily unavailable. Models like RainMachine emphasize local weather processing and offline scheduling, so watering does not stop when the cloud service is unreachable.
Count each separately controlled area (front yard, back yard, side beds, drip lines, etc.) as a zone, then choose a controller that supports at least that many zones with a bit of headroom for future expansion. For example, this guide features options ranging from 6 to 16 zones to cover everything from small suburban yards to larger properties.
Some smart irrigation controllers use free local weather sources, while others may offer premium or subscription-based forecasting services with more advanced features. In this guide, RainMachine is highlighted for working without a recurring subscription, while other brands lean more on cloud-based services tied to their apps.
