Excellent Smart controller for your irrigation system
Excellent product. Easy to program with their App and fairly easy to install However, if you are replacing an existing non-smart Hunter controller and trying to attach it to your house you will have to remove all the internal mechanisms to get to the upper left-hand corner of the controller housing to attach it to your house. A very poor design, which could’ve been easily remedied.

Great Hunter to Hunter replacement option!
Great replacement option if you have a dates Hunter system. Was able to plug and play and reset up zones within 30min. Be sure to take a picture of old wire setup and label like colors with a small piece of tape so you don’t lose track of zones when you go through the installation process.

Replaced a Hunter Pro C. Very easy to install!
Got ripped off by an irrigation guy who charged me to replace everything but what was broken. He stuck me with all new modules for my old Pro C controller, but it turned out that the controller itself was what was bad. Now I had 3 new Hunter modules without a working controller. Fired the irrigation guy and decided to DIY. Since this HPC400 used the same modules as the old Pro C, I got it. Very apprehensive about the DIY part, but it was a snap. This unit comes in its own outdoor box. You just connect the zone wires to the numbered module connectors (mark the wires before disconnecting them from the old controller). There is an easy-to-use connector for the 120V grounded plug, so it is very quick to disconnect it and hardwire the controller if you want. The wifi setup was super quick and simple right through the controller's touchscreen. Finally, the best part of all is the interface with the Hydrawise app. Lots of ways to set up zones and schedules. It uses free weather data for water saving, and it tracks your usage. Very pleased with this purchase.

Nice sprinkler controller
This is nice smart controller. It’s easy to install and connect to your WiFi. Once connected and you have downloaded the app, it is easy to set up the programs to control your sprinkler system. Much easier to use than the standard manual controller.

Some issues but good overall
Old 3 station module wouldn't fit, so I cut the corners to make it work. Hole on bottom is off center towards the front and my pvc connector has to sanded to fit. Other than that things are going great so far. I like that it knows the weather and adjusts watering accordingly. No reason for a sensor.

Lives up to the hype!
I was skeptical about the extra cost of paying for the hunter over a cheap orbit or similar system, but I have to say, after using this system for a while, it is well worth the money. The app has worked flawlessly; the zones were easy to set up, modify, and program, and some of the accessories have made this a great investment. While the other cheap controllers will do most of the same things, this one will do more, easier.
