Hunter HPC400 Sprinkler Controller, 4 Zone, WiFi Smart Sprinkler Timer

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.

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!

Easy installation and easy to program for my home irrigation system. Works as it should, adjusts itself for varying weather conditions.

I upgraded a 3-zone 2000s era Orbit controller with this product. I have installed Hunter controllers for two other locations over the years. I am also experienced with Rain Bird and Orbit but only with locally operated controllers. I have always been happy with Hunter products and two locally-owned nurseries also recommend Hunter. The physical installation was easy, inside a garage: yes I could have used an indoor unit but this waterproof box looks and feels better. While I have not used competitors' apps, the Hydrawise app is excellent. In looking over the competition I don't see anything where Hydrawise falls short. While I am just a handyman and not an irrigation contractor I see why the pros recommend Hunter. The Amazon merchant Sprinkler Parts Warehouse did a fine job fulfilling the order and the package included some helpful last-minute product updates. Next project is to upgrade a six-zone front yard plus a six-zone back yard into one Hunter HPC controller.

This sprinkler controller is typical Hunter quality. We have had a Pro-HC controller for nearly 20 years and never had an issue with it. It's still going strong, but we recently added this HPC400 in another location. Set up is relatively straightforward and programming using the Hydrawise app is easy. So why 4 stars instead of 5? The instructions that come with the unit are for three different controllers plus an add-on and in 5 different languages all in the same step. Very confusing. It took scanning a small QR code and finding a small detail in one illustration to make sure we had the sprinkler wiring correct. Note: the COM connection below the sensor connections is the common for the sprinkler valves. I still highly recommend this timer. It can be mounted outdoors and is lockable if security is an issue.

I replaced an older model Hunter controller. I debated whether to get the new unit that has Hydrawize app but am very glad I did. The controller is fantastic and the app works amazingly well. The app is super easy to use and makes using and programming the controller a breeze. I have not found anything they could do to improve the app. The more I use it the more I appreciate the robust solution that Hunter has provided. I rarely do a review of a product, although I should more often because I study them prior to a purchase. Reviews are helpful In making a more informed decision. This product works so well, all I can say is don't hesitate to buy it!

Very easy install. Replaced an old Rain Bird controller with this and mounted it on an outside wall. Looks slick and easy to see the screen. The screen on the mounted unit updates quickly to match the phone app. Outside controller is helpful in case someone needs to work on your sprinkler system, you don't need to hand over your phone, it can be controlled from the unit. Has more connectivity options in the event more sprinkler zones are added to your yard. Bought a second unit for another house that had 9 zones, just bought the 3 zone expanders and plugged them in. Very simple set up.

It was installed and programmed by a licensed contractor, who was able to explain and demonstrate to to me, a 92 yr. old Great Grandmother of 4, how the Controller works, how the APP on my i-phone is accessible to me if needed. It automatically waters the yard as needed and when needed, without me having to worry about it.

Me gustó las opciones de la aplicación. Ahora es más avanzada al del modelo anterior que tenía. Lo recomiendo

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

Item is amazing, but it's US voltage. This should be made clear on the UK Amazon website. I've since reordered with a local supplier, so I know item is wonderful.

Perfect

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