Today's solar & charge trajectory (full day)

Midnight through now (10% charge currently) is real telemetry, reconstructed hour by hour from actual solar production and battery charge/ discharge. From now through end of day is a forecast, not telemetry: compounds the solar forecast, an average load profile, and (from 16:45 on) the real forcing decision the automation would make. Re-check later for a tighter estimate on the forecast portion.

Hourly export (sell) rate — September, weekday

Not forcing yet today — peak $0.5000/kWh clears the threshold, but the battery hasn't recovered enough to safely export (10% charge now, floor is 29%). Re-checked hourly; the real decision locks in at 16:45.

Revenue

Actual = real grid export × that hour's real sell price (from live telemetry). Expected = the forced window's planned target energy × peak price (what the automation aimed for; days recorded before target_energy_kwh existed are estimated from today's config).
