In Matter-based smart home systems, sensors often operate on event-driven reporting or have configurable reporting intervals. A gap in data (or a null representation in logs where no new value was sent) is standard behavior when the measured value has not changed significantly or the reporting interval has not elapsed. There is no evidence of a 'fault' state (e.g., error codes, stuck values), only a lack of *new* data points during those specific minutes. The sensor resumes normal operation immediately after, with valid readings at 16:30 (before) and subsequent chunks show consistent reporting patterns elsewhere.
