Steps

  1. Confirm your IoT hub is on the Standard tier — scheduled jobs aren't available on the Basic/Free tier
  2. Build a device query to target the device set, e.g. `deviceId IN ['MyDevice1','MyDevice2']` or a twin query condition
  3. For a bulk direct method call, send `PUT https://<hub>/jobs/v2/<jobId>?api-version=2021-04-12` with `"type": "scheduleDeviceMethod"` and a `cloudToDeviceMethod` object (methodName, payload, responseTimeoutInSeconds)
  4. For a bulk twin update, send the same PUT with `"type": "scheduleUpdateTwin"` and an `updateTwin` patch object that includes a matching etag (e.g. `etag: "*"`)
  5. Set `queryCondition`, `startTime` (ISO-8601), and `maxExecutionTimeInSeconds` on the request, then poll `GET https://<hub>/jobs/v2/<jobId>?api-version=2021-04-12` to track `deviceJobStatistics` (succeeded/failed/pending/running counts)
