Sun-Chasing Charger — Pour Your Solar Surplus Into the Car, Not the Grid

You'll walk away with: A Home Assistant "solar router" that Claude Code wrote for you — it reads your whole-home energy monitor live, computes your real-time solar surplus, and pours that surplus into your flexible loads in priority order (EV charger first, then heat-pump water heater, then pool pump), modulating the car's charge current amp-by-amp to track the sun, backing off the instant a cloud or a kettle eats the headroom, refusing to pull expensive grid power for a discretionary load during peak-tariff hours, and never letting the total controlled load push your main breaker past a ceiling you set — all local, all free to run, with every line of the surplus math and the control logic delegated to Claude.
