Hydro-Rain HRC 400 Wi-Fi Smart Irrigation Controller: Smart watering based on conditions
The Hydro-Rain HRC 400 is for homeowners who want a smarter, more efficient way to water their lawn. Instead of guessing when to water, you can rely on real-time weather data and site-specific conditions.
This smart controller uses live weather feeds and historical evapotranspiration to adjust watering automatically. You can also manually set a rain delay for 24 hours up to 32 days. The factory-installed power cord means no complicated wiring. The hinged panel door gives you quick access to valve connections. Control multiple devices from one app, making it easy to manage your entire property.
Set up watering schedules based on slope, soil type, and sun or shade. The personal experience: you get a notification after a storm and the controller automatically skips a cycle, saving water and preventing runoff.
