I have had my 12-zone Yardian Pro about a month now. Right out of the box it was simple to setup and easy to get started. Now about the programing...you can choose to set it up manually by choosing a duration and start time for each zone, or take some time to input a bunch of data for each zone, like plant type, soil type, slope angle, sun/shade, type of sprinkler heads or drippers, flow rate for heads and drippers, and choose your local NOAA radio weather station. The Yardian will automatically calculate desired soil moisture, monitor local weather conditions and forecasts, including rain amounts, rain chances, humidity, wind, sky cover, etc., and then build a model for the amount of water needed by each zone to optimize soil moisture and water usage. It then determines run times for each zone and builds a "smart" schedule which can be interrupted/delayed by conditions like a recent rainfall threshold or precip probability. You can also integrate it with Apple Home Kit to manually start or stop zones using Siri. In a word, "slick." So, whether you prefer simple or complex, this could be the best smart irrigation controller you can buy.

Lots of control in the Yardian and Home iOS app. Super intuitive and easy to install. Received $80 rebate from my state's Waterwise program.

The main reason I purchased is because of the simple intergration with Apple Homekit. I later had an issue with one of my control valves and the customer service was very responsive and solved my problem immediatly. I highly recommend this sprinkler controller.

Other companies should model their customer service program after this one. Not only do they respond quickly, but they are on top of communication to customers when action needs to be taken, software to be updated, etc. They also take responsibility for problems that are encountered with the product. I can't say enough about the customer service here. Now, the reason for 4 stars, the product is just not super user friendly. I'm pretty technical and I found it very challenging to get set up. However, customer service is there to help. Now that it is all set up, it's working great! Integrates with Apply HomeKit great, too. No issues.

TLDR: Great irrigation controller, works perfectly with Homekit.

I live in the Apple ecosystem and until Matter takes over the world and allows everything to integrate, I need to have HomeKit enabled devices. When I needed to make some irrigation system changes, I tossed the old Rain Bird controller and got myself a Yardian.
Setup was super easy, the app is intuitive enough to use with an instruction manual or YT video and it works. There isn't much more to say. The app has a lot of powerful features allowing for multiple programs that are triggered by weather events or other sensors connect to the Yardian.
I personally just set up manual programs for my different zones and they work every time without fail.
I don't really have any complaints about this system other than the app interface. I think it could do use a quick start helper program like my Ecobee where is walks you through step by step programming. But I was able to figure it out and I attended public school so most everyone should be able to do it too.
