Got my first Rachio in 2016. Moving to this year i have purchased 4 units. Two 16 zone units for the condominium property i live at. I’m on the board and take care of the grass watering. We have a 26 zone system. Hope that rachio will save us some money this year and reduce our water waste. The other two 8 zone units are at my mother-in-laws and her sister town homes. Hoping to improve their grass this year. I know what the Rachio system can do so it should be a interesting year. Right now my learning is around fine tuning my zone programing at my condo. We have a challenging property. Shaded areas, high sun areas and steep hilly zones along with flat areas. So its going to be fun.
