With Rachio you have a smart controller but you are still working with dumb valves. Rachio should come out with a Rachio valve to replace your dumb valves. A smart valve would know if it worked or not (was there a short or a break in the line and the valve could not be reached), flow - how much water flowed thru the valve. This information could be communicated back to the rachio controller similar to using Internet over the power line, that is, use the existing copper to transmit this information back to the controller. Rachio, you have a smart controller but you are living with a dumb valve.
