Starting with 4 zones and expandable to 16, it uses real-time weather data to automate watering schedules, saving water and protecting your landscape. Featuring built-in fault detection and compatibility with flow meters and remote controls, it offers seamless remote management via smartphone apps and voice assistants. EPA WaterSense approved, it’s the smart choice for efficient, modern irrigation. ## Description The Pro-C Hydrawise combines the power of Wi-Fi-based irrigation management and the convenience of modular functionality into one next-generation controller. The Pro-C Hydrawise helps contractors save time, save water, protect landscapes, and meet the demands of customers who want smart home solutions. In addition, it lets contractors continue using their Roam and Roam XL remotes for quick on-site management. Among the controller's many robust features is Predictive Watering, which adjusts irrigation schedules based on local, real-time temperature, rainfall probability, wind, and humidity. A built-in milliamp sensor makes troubleshooting wiring issues easy. By adding a simple-to-install HC Flow Meter, users can receive notifications regarding leaking pipes or broken sprinklers. Users can also manage the controller from anywhere using a smartphone, tablet, or computer. The Pro-C Hydrawise is EPA WaterSense approved. Hydrawise is also compatible with desertcart Alexa for convenient voice control to start, stop, and suspend irrigation. Review: Moves Irrigation Control Into the 21st Century - The builder installed a Hunter Pro-C controller, which worked fine. However, I wanted something that was more versatile and convenient. Wow. What a nice surprise. Others have described this component well, but the interface on the phone was worth the purchase to me, and I am not a geek that loves technology for technology's sake. Very intuitive set-up. Yes, it is as easy to convert the Pro-C to the HPC as others have said. Programming was easy peasy. Changing programming is so easy it almost seems like cheating. One note: when I first tested the system, my irrigation did not come on. I remembered that I have a master solenoid valve as well as zone valves. It is a simple toggle in the set-up menu and all is well. This system also has many built in weather adjustments you can use and a way to automatically cycle the zones that tend to have runoff to minimize wasted water. Really very capable system. Review: Has WiFi and Phone App - Works great - I replaced a 12-year-old Hunter Pro-C controller that was starting to malfunction, including watering two zones simultaneously. After some investigation, I discovered that the issue was caused by faulty zone expansion modules—a common problem according to my local irrigation supply house specialist. While I could have simply replaced the modules, I decided it was time for an upgrade. I opted for a WiFi-enabled model with a phone app and weather forecast integration, and I'm glad I did. The controller comes with a standard module which is just 4 zones and the main valve. I had to purchase both the 3 and 9 zone expansion modules to get to the 13 zones I need for my house since you need to increment with the 3 zone module first and can't just add a the single 9 zone module by itself. The setup was seamless, connecting to my 2.4G home WiFi was easy, and I opted to program the zones and settings using my laptop with the Hydrawise website. I was also able to reuse my existing rain/freeze sensor as well as my "Roam" remote, which was good (if not redundant). So far, everything is working flawlessly. I’m extremely satisfied with this upgrade and would definitely purchase it again or recommend it to a neighbor! ## Features - 4 Zone Timer Expandable to 16 Zones with Optional Expansion Modules - Can be used indoors with included 5' lead and plug or remove power cord and hardwire into a junction box.

This makes it a plug-in "indoor" timer or an outdoor timer.

The setup wizard on the app is a little buggy but once I got it all set up configuring zones and creating a program was easy. All in, took me about 15 minutes to switch all my wires and modules from the Pro-C over and set up my first program. Glad I just did it myself because my Sprinkler company offered me a "special deal" to install one of these for nearly $700! Pays to learn how to do this stuff yourself because it's not hard at all and you absolutely don't need a contractor to do it for you and rip you off. One gripe: the predictive watering stuff seems a little wonky. It rained last night and I have the default predictive settings on to not water if there's 0.1 in rainfall or 80%+ chance of rain, and it still ran. Yes, I have my location and everything set up correctly. Chalking it up to first watering weirdness so will see if it improves. If not, I'll have to set up a smarter automation in Home Assistant to toggle watering for that day. Speaking of Home Assistant, I set up the integration in minutes and it works great, so I can turn on watering or any zone easily from HA. ## Frequently Bought Together - SPW Hunter Hydrawise HPC-400 4-16 Station Wi-Fi Controller Web-Based i-Phone Android App 4 Zones Expandable to 16 Zones with Optional Expansion Modules HPC400 - Hunter Sprinkler PCM300 PC 3-Station Plug-In Module - Hunter PCM-900 9 Station Expansion Module, Add Zones to Hunter Pro-C and Hydrawise HPC Controllers, Easy Install Irrigation System Upgrade, Sprinkler Timer Add On --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.ae/products/82998499-hunter-hydrawise-hpc-400-4-16-station-wi-fi-controller](https://www.desertcart.ae/products/82998499-hunter-hydrawise-hpc-400-4-16-station-wi-fi-controller) --- *Product available on Desertcart United Arab Emirates* *Store origin: AE* *Last updated: 2026-06-05*
