Govee Device Control API

  title: Govee Developer API
  version: '1.0'
  description: >-
    The Govee Developer API is a free, cloud REST API for controlling and
    querying Govee smart lighting and smart-home devices. All requests are made
    over HTTPS to https://openapi.api.govee.com/router/api/v1 and authenticated
    with a Govee-API-Key header (the key is issued in the Govee Home App). The
    API is capability-based: GET /user/devices returns each device's typed
    capability list, POST /device/state queries live state, and POST
    /device/control sends a single typed capability command. Dynamic (light)
    scenes and user-authored DIY scenes are enumerated with POST /device/scenes
    and POST /device/diy-scenes, then applied through the control endpoint.

    Endpoints in this document are grounded in the public Govee Developer API v1
    reference (developer.govee.com). Request and response schemas are modeled
    from the documented capability structure; exact per-capability value shapes
    vary by device and should be read from GET /user/devices.
