  title: Govee Developer Device Control Device State 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.'
