  title: Tibber Submit Meter Reading
  summary: Discover the viewer's home over GraphQL, then submit a manual meter reading for that home with the sendMeterReading mutation.
  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 submits a manual meter reading for that home using the
    sendMeterReading mutation with the home id and the reading value supplied as
    GraphQL variables. Because the GraphQL API exposes a single POST operation,
    every step reuses the executeGraphQL operation with a distinct documented
    payload. Each step spells out its request inline so the flow can be read and
    executed without opening the underlying OpenAPI description.
