  "conclusion": {
    "en": "For the investigated SwitchBot Plug Mini (JP), OpenAPI v1.1 can legitimately return unchanged electrical status values for extended periods because reporting uses load-band-specific change thresholds rather than guaranteed periodic fresh publication of all fields. Around a 110 W load, SwitchBot's development team stated that a 30 W change was required for a report. Therefore, one- or five-minute polling does not imply measurement freshness at the same cadence. Long-running collectors should track retrieval time and freshness separately and detect stale runs explicitly. The app-triggered refresh mechanism and atomicity of accompanying status-field updates remain unverified.",
    "ja": "今回調査したSwitchBot Plug Mini (JP)では、OpenAPI v1.1が長時間同じ電気量statusを返すことは、負荷帯別の変化しきい値を用いる報告仕様によって正常に起こり得る。約110W負荷では、SwitchBot開発部門は報告に30Wの変化が必要と回答した。このため1分または5分周期でAPIを取得しても、その周期で測定値が新鮮であることは保証されない。長期収集では取得時刻とfreshnessを分離し、stale連続を明示的に検出すべきである。アプリ詳細画面に伴う更新メカニズムと報告時の各status fieldの同時更新保証は未検証である。",
