  title: Tibber Price Alert Push
  summary: Read the current price level over GraphQL, branch on whether power is cheap, and push a Tibber app notification when it is.
  description: >-
    Two chained GraphQL operations against Tibber's legacy /gql endpoint that
    turn the current price level into a mobile push. The first query reads the
    current hourly price and its level classification; the flow then branches on
    the level so that only a CHEAP or VERY_CHEAP hour triggers the
    sendPushNotification mutation, while normal or expensive hours end quietly.
    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.
