Hunter Hydrawise HPC400 Smart WiFi Irrigation Controller for Lawns and Gardens, 4 Zone, Expandable to 32 Zones, Weather Based, App Controlled Sprinkler System

This controller has completely transformed how I manage my irrigation system. Being able to control everything from anywhere in the world is not just convenient—it’s incredibly powerful. Whether I’m at home or traveling, I can monitor, adjust, and fine-tune my system right from my phone. One of the biggest advantages is that I’ve been able to give my landscaper access as well. That means adjustments can be made in real time without back-and-forth calls or guesswork. It’s streamlined communication and made maintenance far more efficient. The app is intuitive and easy to use, even if you’re not particularly tech-savvy. Scheduling, zone control, and adjustments are all straightforward. Plus, the smart features—like weather-based adjustments—help prevent overwatering and save money on water bills. Installation was smooth, and once it’s set up, it really just works. Reliable, flexible, and incredibly convenient. If you’re looking to modernize your irrigation system and want full control at your fingertips, this is absolutely worth it. A true game-changer.

Took 25 min to install and makes everything easy for my system. Can control from my phone anywhere and the smart features are great

This is the ultimate upgrade in sprinkler technology. No more standing in front of your controller to turn on an area and running around the house try to see if the area you turned on is actually working. This was a super easy upgrade for me, I literally just popped the faceplate off of my existing one and installed this with a single ribbon cable! There’s a completely free app that lets you connect to it through your phone, you name your areas, and you can setup all kinds of schedules, and get insights to how much water you’ve used recently in comparison to previous weeks. It looks really good in the app and the touch screen works great as well. It has built in prediction with rain and heavy sun to accurately detect when to water less or more. Once you get this you won’t be going back! It was so good, I bought a second one just to give to my neighbor as payback for a favor!

This might seem a bit expensive but I swear to you it is worth every penny. Very simple to wire, easy to connect, and the app is great.

Only had it for a day so can't say too much yet but programming watering programs is super easy..Customer support is non existent. You can chat with A.I. or refer to documentation on line..I have one simple question and there is no answer anywhere. Will revisit review after more use but the programming through the app is a breeze.

Works well but it will disconnect from wifi

Awesome Product. I had old Hunter PC-400i. Replace and install very easy, it takes less than 5 min with testing all zones. App quality is superior. You don't need physical rain sensor. App automatically connected to Weather app. Wifi range is also good. It worth more than $200++

Easy to install (if the existing wiring is present) and easy to program and use. Big improvement over the old timer box.

Great product. Love the simplicity once you get by the wiring which takes some time.

Perfect

Easy installation. Case is bulky so make sure you have the space.
