What you'll do
A live whole-home power dashboard — watts right now, kWh today, and each mains leg on its own line — running entirely on your own hardware and your own LAN, with no cloud account and no utility app watching your habits. Claude Code wrote the ESPHome firmware and the dashboard queries; you built and calibrated the low-voltage sensor, a licensed electrician placed the clamps in the panel, and you proved it by watching the kettle spike in real time.
