Field notes
The household form accounts for details that can shift a bill, including central AC, pools, rooftop solar and whether an ADU shares the main house’s meters. Users can select a typical home first and adjust its assumptions; the page also describes an optional bill-based calibration that stays on the device. The map uses Census boundary files and energy-service territories, with a warning that utility lines may not match city limits.
