Rachio 3: Where It Has the Edge
Rachio 3’s Weather Intelligence Plus calculates evapotranspiration precisely — adjusting watering to replace exactly the water that plants lost rather than guessing based on calendar or simple weather skip. This produces measurably lower water usage than any competing approach. The flex scheduling also adjusts watering frequency and duration independently per zone based on actual soil moisture models.

Wyze Sprinkler Controller: Where It Has the Edge
Wyze Sprinkler Controller covers the basics at $49: Wi-Fi control, weather-based skip, scheduling, and Alexa/Google integration. The weather skip logic is simpler than Rachio’s ET calculation but prevents the most wasteful scenario (running during rain). For households where smartphone control and weather skip are the goals — not optimization — Wyze delivers at a price that’s difficult to argue against.
