In my case, I have a system in an appartments complex 2,000 miles away. So I absolutely HAD to get my settings right. If the grass died, the residents would have been up in arms !!!
One mistake I did make early on was to assume the soil type. This meant that retention in the soil was less than the Rachio thought, and some places became quite bare. Thankfully I rescued the situation in time, as I visited the complex just before the summer heat arrived.
The system is fantastic. I don’t need to check it anymore, other than just ensuring it’s online.
I do think the app could be better with offline notifications, between the controller or the chosen weather station.
