Hunter Hydrawise HPC400 Smart WiFi Irrigation Controller for Lawns and Gardens, 4 Zone, Expandable to 16 Zones, Weather Based, App Controlled Sprinkler System

Works Great. Easy to install and able to control my sprinklers from my phone now.Easy to set-up and program. So convenient.

Easy to install and set up and I am not a techy person. Love running it from my phone.

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.

Works great. Love it. Very easy to install. Extremely User friendly..

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.

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.

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.

Pros:* The concept is great - being able to control the sprinklers and the watering schedule remotely using an app is a lawn-saver if you travel over the summer.* I installed as an upgrade from an older Hunter controller and it was not terribly difficult.* I had a good customer service experience with them (a few years back)Cons:* IMHO, the app user interface is not intuitive. It can be very confusing figuring out even basic use cases like manually start/stop a zone, see what days it actually watered (or suspended) from last week/month, test the live connection to the controller, find your contractor and authorize their connection, etc..* The app can lose contact with the controller and give false information (like showing it as watering when it is not).
