We installed a new irrigation system with the Rachio Wireless controller. How accurate is the water usage on the Rachio? We seem to have a major discrepancy between the county water bill and what Rachio claims as usage for the last quarter. The county claims we used 60,000 more gallons than what Rachio reports for the same period. Our household usage in a quarter is typically between 20,000 to 25,000 gallons, so trying to figure out how accurate the Rachio is.
