Peak recorded load i Peak recorded load Highest Main watts ever seen — from the in-memory accumulator this hour and the SQLite history of all previous sessions. Only ever climbs; resets only if the database is cleared. The grey tick marks the NEC 80% continuous-load limit (24,000 W), above which sustained draw is unsafe for a 125 A service. —

Live vs expected i Live vs expected Green bar is the current Main draw, updated every second via SSE. The amber marker is the learned baseline — average peak wattage for this same hour of day across all past sessions. Turns amber when live exceeds expected by more than 30%.
