Short Answer
Hunter Hydrawise is a smart irrigation controller that connects to Wi-Fi or a cellular network and uses local weather data to adjust watering automatically. Instead of running a fixed schedule, it checks the forecast and adjusts each zone's run time, skips watering before rain, and can be controlled from a phone app anywhere in the world. An optional flow sensor adds leak detection and automatic shut-off.
How Hydrawise works
Hunter Hydrawise is a smart irrigation controller that connects to your Wi-Fi or a cellular network and uses local weather data to adjust watering automatically. Instead of running a fixed schedule like a conventional timer, Hydrawise checks the weather forecast and observed rainfall, temperature and humidity, and adjusts each zone's run time accordingly.
It skips watering before rain is due and scales run times by temperature and season.
Remote control from your phone
You can monitor and control every zone from the Hydrawise app on your phone, from anywhere in the world.
Flow monitoring and leak detection
An optional flow sensor adds leak detection, shutting off the master valve automatically and alerting you by phone if a pipe bursts or a valve sticks open. This is a fundamental improvement over a timer, which waters on a fixed schedule regardless of conditions and cannot alert you to a fault.
Key Takeaway
Hydrawise replaces a fixed timer with weather-based scheduling, remote control from a phone, and optional flow monitoring for leak detection — a fundamental improvement over a conventional timer.
Frequently Asked Questions
Does Hydrawise need Wi-Fi?
It connects to Wi-Fi by default, but a cellular module is available for sites with poor signal, so no Wi-Fi is needed.
What happens if the internet drops?
Hydrawise keeps running its last schedule offline and resyncs automatically when the connection returns. Your plants are never left unwatered by a network outage.
Can Hydrawise control multiple zones?
Yes. Hydrawise controllers are available from 8 to 54 zones, with expansion modules for larger systems.
Does Hydrawise work with existing irrigation systems?
Yes. Hydrawise can replace an existing controller provided the solenoid valves and wiring are in good condition. No changes to the underground pipework are needed.
