Tibber Current Price By Home

  title: Tibber Current Price By Home
  summary: Discover the viewer's homes over GraphQL, then fetch the current hourly Nord Pool price and price level for the chosen home.
  description: >-
    Two chained GraphQL operations against Tibber's legacy /gql endpoint. The
    first resolves the authenticated viewer and the list of homes, capturing a
    home id; the second requests the current hourly price node for that home,
    returning the total, energy, and tax components together with the price
    level classification. Because the GraphQL API exposes a single POST
    operation, every step reuses the executeGraphQL operation with a distinct
    documented query payload. Each step spells out its request inline so the
    flow can be read and executed without opening the underlying OpenAPI
    description.
