Hydrawise Irrigation Controllers: Smart Watering for Sonoma, Napa & Marin County Homes

Written By Scott Anderson


Water is one of Northern California’s most valuable resources — and also one of the most commonly wasted. For homeowners in Sonoma County, Napa Valley, and Marin County, efficient irrigation is no longer a luxury; it’s a necessity. Changing weather patterns, ongoing water regulations, and rising utility costs all demand a smarter approach to landscape irrigation.

At Scott Anderson Landscaping, we install and manage Hunter Hydrawise® irrigation controllers because they represent the most advanced, reliable, and water-conscious irrigation technology available today. This blog will explain what Hydrawise irrigation timers are, how they work, why they save water and money, and why they are ideal for homes and estates throughout Sonoma, Napa, and Marin County.

What Is a Hydrawise Irrigation Controller?

A Hydrawise irrigation controller is a smart, Wi‑Fi–enabled irrigation timer developed by Hunter Industries, one of the most trusted manufacturers in the irrigation industry. Unlike traditional irrigation clocks that water on a fixed schedule, Hydrawise controllers use real-time weather data, predictive technology, and system monitoring to automatically adjust watering based on actual conditions.

In simple terms: your landscape gets the water it needs — no more, no less.

Hydrawise controllers are commonly referred to as:

  • Smart irrigation controllers

  • Wi‑Fi irrigation timers

  • Weather-based irrigation systems

  • EPA WaterSense–approved irrigation controllers

All Hydrawise controllers connect to the Hydrawise Irrigation Management Platform, allowing both homeowners and professionals like Scott Anderson Landscaping to monitor, adjust, and protect irrigation systems remotely.

Why Traditional Irrigation Timers Waste Water

Many homes throughout Sonoma, Napa, and Marin County still rely on outdated irrigation timers. These systems:

  • Water on fixed schedules regardless of weather

  • Continue running during rain or cold weather

  • Don’t detect leaks, broken valves, or stuck zones

  • Often overwater lawns, shrubs, and trees

Overwatering doesn’t just waste water — it can:

  • Damage plants and root systems

  • Cause fungal growth and disease

  • Increase runoff and erosion

  • Inflate monthly water bills

Hydrawise solves these problems by automating smarter decisions that a traditional controller simply cannot make.

Predictive Watering®: How Hydrawise Saves Water

One of the most powerful features of Hydrawise is Predictive Watering® Technology.

Hydrawise uses:

  • Past weather data

  • Current weather conditions

  • Forecasted weather data

  • Local weather stations

  • Daily evapotranspiration (ET) rates

Using this information, the system automatically adjusts irrigation schedules every single day. If rain is coming, watering is reduced or paused. During heat waves, watering increases just enough to keep plants healthy.

For homeowners in Sonoma, Napa, and Marin County, where microclimates can vary dramatically from neighborhood to neighborhood, this technology is critical. Your irrigation schedule adapts to your exact location, not a generic seasonal setting.

Result: healthier landscapes and significant water savings.

EPA WaterSense® Approved Irrigation

Hydrawise controllers are EPA WaterSense® approved, meaning they meet strict federal standards for water efficiency and performance.

For homeowners, this means:

  • Proven water-saving technology

  • Responsible irrigation practices

  • Compliance with California water-efficiency expectations

In many cases, installing a WaterSense-approved irrigation controller may also help support rebate eligibility through local water districts.

System Monitoring: Protecting Your Landscape Investment

Your landscape is an investment — and irrigation failures can destroy it quickly.

Hydrawise controllers offer advanced system monitoring, including:

  • Flow monitoring (with optional flow meter)

  • Valve and wiring fault detection

  • Leak alerts

  • Automatic notifications

If a pipe breaks, a valve sticks open, or abnormal water usage is detected, alerts are sent immediately. This allows our irrigation team at Scott Anderson Landscaping to respond quickly — often before serious damage occurs.

This is especially valuable for:

  • Large residential properties

  • Vacation homes

  • Vineyards and estates

  • Commercial and HOA landscapes

Remote Access for Homeowners

Hydrawise allows homeowners to manage irrigation from anywhere using a:

  • Smartphone

  • Tablet

  • Computer

With the Hydrawise app or web dashboard, you can:

  • Check when your system last ran

  • Pause irrigation during rain

  • Adjust schedules while traveling

  • Receive alerts if there’s a problem

No technical background required — the interface is clean, simple, and user-friendly.

Hydrawise Controller Options

Hydrawise is not a one-size-fits-all system. Hunter offers multiple controller models depending on property size and irrigation needs:

Residential Systems

  • Pro‑HC Controller: Perfect for most residential landscapes

Larger Residential & Commercial Systems

  • HPC Controller: Modular and expandable for growing landscapes

Each system is scalable, reliable, and built to last — and our team selects the right controller based on your specific property.

Ideal for Sonoma, Napa & Marin County Landscapes

Northern California landscapes are diverse. From drought-tolerant gardens and vineyards to lush lawns and ornamental plantings, irrigation must be precise.

Hydrawise controllers are ideal for:

  • Hillside properties

  • Coastal climates

  • Vineyards and wine-country estates

  • Water-restricted areas

By adjusting irrigation automatically, Hydrawise protects both plants and water resources — something increasingly important across California.

  • Reduced water bills
