Eaton EV Only API

openapi: 3.2.0
info:
  title: Eaton Smart Breaker Authorization EV Only API
  description: 'REST API (formerly the Energy Management / EM API) for Eaton AbleEdge Smart Breakers and Eaton Green Motion EV Smart Breaker Chargers. Lets developers commission, monitor, and control devices, model panels and locations, run batch commands, and pull real-time and historical energy telemetry. Devices are typed via `hardwareType` — `emcb` for standard smart breakers, `ev-emcb` for EV chargers.


    Authentication: every request must include `Em-Api-Subscription-Key: {SMART_BREAKER_API_KEY}` and `Authorization: Bearer {AUTH_TOKEN}`. Tokens are obtained from the OAuth2 token endpoint via Client ID + secret (Base64-encoded Basic auth) and are valid for 1 hour.


    This OpenAPI spec is reconstructed from the public Eaton developer-portal documentation (https://api.em.eaton.com/docs and https://api.em.eaton.com/preview/docs) and the AbleEdge Smart Breaker developer portal (https://portal.em.eaton.com/). It is intended for cataloging and capability mapping in API Evangelist tooling, not as a substitute for the authoritative provider spec.
