Ratebook for Home Assistant v0.1.0
First release of the Ratebook Home Assistant integration — HACS-installable.
Live US electricity-price + cheapest-charge-window sensors over the open, deterministic Ratebook rate engine. Self-contained (engine vendored — no PyPI/network deps). Bundles 15 real US utilities (PG&E, SDG&E, SCE, ConEd, Duke, DTE, Dominion, Eversource, FPL, Georgia Power, National Grid, PSE&G, APS, SRP, Xcel) plus a reconfigure flow.
Install: HACS → Custom repositories → add this repo as an Integration → install → restart → add the Ratebook integration.
