Water Systems

Smart irrigation controllers replace manual sprinkler timers with Wi-Fi-connected systems that read local weather and adjust watering automatically. This category compares the controllers homeowners actually buy in 2026: the Rachio 3 for its weather intelligence and Alexa/Google/HomeKit support, Orbit B-hyve as the budget-friendly pick, Hunter Hydrawise for flow-sensor leak detection, and Rain Bird's ESP-TM2 and ARC-series for straightforward wire-for-wire upgrades. You'll find zone-count guidance, drought-restriction compliance notes (a real concern in cities like Denver and Tampa), and honest comparisons of DIY install time versus professional setup — all aimed at helping you water less and grow more.
