BUYING GUIDE
How Many Zones Do You Need?
Count the number of valve wires at your existing controller (exclude common and power wires). Each wire is one zone. Buy a controller with at least that many zones. An 8-zone controller works for most residential systems. Larger properties may need 12 or 16 zones.

Weather Intelligence Features Explained
Smart controllers use local weather data to skip or reduce watering. Basic systems skip on rain days only. Advanced systems like Rachio use evapotranspiration (ET) calculations that factor in temperature, humidity, wind, and sun to determine exactly how much water your soil lost since the last watering.
