Automatic Irrigation Controllers

Match the controller's number of stations (zones) to the number of valve-controlled areas in your irrigation system, and pick a model that supports future expansion if you plan to add zones; residential controllers commonly handle 4–16 zones

Prioritize station/zone count, programmability (multiple start times and independent runtimes), weather or soil-moisture sensors compatibility, remote/cloud access if you want app control, and compatibility with your local water pressure and valve types

Smart controllers that use weather data or soil-moisture inputs can reduce overwatering by automatically adjusting schedules; common connectivity options include Wi‑Fi for cloud/app control and sometimes local Bluetooth, while some models accept wired sensor inputs

Most controllers are wall-mounted and replace existing timer units; ensure electrical requirements match (typically 24VAC transformer) and that the controller supports the valve type and sensor inputs you use; simple systems can be DIY, but complex or multi-voltage systems may need a professional

Prices vary by features and brand: basic non‑smart controllers are available in lower budget tiers (often under $50), mid‑range and smart Wi‑Fi controllers commonly fall around the $100–$300 range, and advanced commercial-grade systems cost more

Check and replace backup batteries annually if present, keep the enclosure closed and weatherproof, update firmware for smart models when available, and test each zone seasonally to confirm wiring and valve operation

Yes — outdoor-rated controllers have weatherproof enclosures and are designed to be mounted outside near valves, while indoor controllers require installation in a protected location such as a garage; choose the type that matches your installation site
