Praise

My Rachio controller was super easy to install myself. Really took my time so was about an hour to finish. App is one of, if not the best I’ve used .. very well designed and super easy to learn & use (Wi-Fi is awesome to have!). Couldn’t be more satisfied.

Easy to install and when I needed support they actually responded on a holiday. Here is an image with the cover off showing how simple it is to do the wiring.

Complaints

Rachio 3 does a poor job of determining weather in our area. It wants to use mom and pop personal weather stations (most without rain gauges) and refuses to stay locked onto NWS stations that are more reliable.

Susan W., Lowes.com 11/12/2018

I used to love my Rachio, but the current software has bugs. My system will only water on every 3rd day now, no matter what you do to the schedule. It isn’t a “rain skip” or “seasonal adjustment”.
