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

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.

We replaced an old Hunter Douglas controller with this model and are SO glad that we did. The option to control the water from my phone with the easy to use app has saved me from trudging to the garage many times to turn the water on or off. Plus our water bill was substantially lower as it only waters when needed. 100% reccomend.

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!

Device was easy to install in place of our old hunter system.Installation took approximately 30 minutes including the programmingInterface to Iphone is easy to use and well thought out.This device can be controlled by your phone android or AppleThe plus is you can also adjust settings right on the unit if neededSimplifies adjusting heads. You can trigger zone remotely for checking, no need to walk back to the box.Box seals well and is lockableGreat price and I would buy again.

This system replaced an old manual Hunter sprinkler box. Most physical interfaces were different as well as the mounting. Main issue is the poor/lack of integration with Google, Homeseer and Hubitat. Rachio, Rainbird and Orbit appear to have more options.

Was easy to install and love using the app to control the system. We live in the desert and it automatically adds a little water time to days that are extremely hot.

I was looking to upgrade our Pro-C model (with the dial and blue buttons) to be Wi-Fi enabled, so it’s easier to adjust programs and test zones without walking back and forth all the time. That upgrade is really just an HPC faceplate but is hard to find by itself, and when you do it’s almost the same price as this entire unit. So I bought this just to use the faceplate! (And if something ever happens to the main board of the Pro-C it’s nice to know we have a backup device that could replace it.)Swapping it into our Pro-C was a breeze: unplug the power, detach the ribbon cable, detach the old faceplate, attach the HPC one, attach the ribbon cable, and plug it back in. There’s a tiny touchscreen to get connected to your Wi-Fi (2.4 GHz only) and then you add the serial number to your Hydrawise account and you’re set. So much easier to program now, and the customizable temperature and precipitation adjustments give you more control.

Had some issues with my old Pro-C controller (installed in 2007) only working on program A. Wanted to update to a Wi-Fi one, so researched and found this Hydrawise HPC-400 controller. It came with base module for zones 1-4. Cool thing was I could use the HPC-300 module from my old controller for zones 5-7, so I did not have to buy an extra module (saved $42-48). All the terminals were one for one, so I just labeled all the wires disconnected and reconnected. I was impressed with how easy it was to swap. Setup was really easy as well. Nice interface, you can control from PC through the web, or via mobile phone or tablet. Probably saved myself about $350 by DIY.What a blessing, now I do not have to run back and forth between sprinklers and the controller in the garage when I am testing or troubleshooting. Hahaha.
