Rachio, Hydrawise, and Rain Bird LNK — what smart controllers actually do, what they save, and when they make sense.
If you still have an old clock-style sprinkler controller, you're almost certainly overwatering. Smart controllers pull local weather data and skip cycles automatically — and in the Charlotte area, that adds up to real money.
What they actually do
Smart controllers (Rachio 3, Hunter Hydrawise, Rain Bird LNK) connect to Wi-Fi, pull local weather forecasts, and adjust watering based on rain, temperature, and evapotranspiration. You also get phone control, leak alerts, and zone-by-zone scheduling.
Real savings in Charlotte
Most Charlotte homeowners we upgrade see a 20–40% drop in summer water bills. On a typical $150–$250 summer bill, that's $300–$600 saved per season — enough to pay for the controller in one year.
When it makes sense
Almost always. Smart controllers cost $250–$450 installed, and they pay for themselves quickly. The only time we don't recommend one is on a tiny one- or two-zone system where the savings are minimal.
