  title: ThingSpeak Inspect Channel and Aggregate Feed
  summary: Read a channel's settings, then pull an averaged feed over a recent window.
  description: >-
    A reporting flow that first reads a channel's metadata to confirm it exists and
    capture its last entry id, then reads its feed over a recent day window with
    server-side averaging applied so a dashboard can plot a smoothed series. Every
    step spells out its request inline so the flow can be read and executed without
    opening the underlying OpenAPI description.
