Water Cost Tracking allows users to configure pricing models and track irrigation expenses using either actual flow sensor data or estimated runtime-based flow rates. It supports fixed, tiered, and seasonal-tiered pricing structures, making cost reporting adaptable to different utility billing formats. Users can view costs across sites, controllers, programs, and stations, with drilldowns, custom time ranges, billing-period trends, and export options for further analysis. By combining sensor-based accuracy with sensor-free estimation, this feature helps users understand water spending, identify high-cost areas, and manage irrigation budgets more effectively.
