{"response":"### Energy Status Summary: Main Refrigerator\n\n**1. Overall Status:**\nThe refrigerator is operating within stable parameters with 100% voltage compliance, consuming 12.01 kWh over the 23-hour monitoring period at an average draw of 519.75W.\n\n**2. Key Metrics Summary:**\n*   **Power:** Current 532.9W (Avg: 519.75W; Range: 489.5W\u2013591.4W).\n*   **Voltage:** Current 225.3V (Avg: 230.89V; Range: 219.6V\u2013241.8V).\n*   **Efficiency:** Power Factor (PF) is low, averaging 0.70 (Current: 0.74).\n*   **Cost Impact:** Total consumption of 12.01 kWh equates to an estimated cost of 1,321.10 PKR for the monitoring period.\n\n**3. Notable Observations:**\n*   **Power Factor:** The PF average of 0.70 is suboptimal for a commercial refrigeration unit, suggesting potential motor inefficiency or reactive power waste.\n*   **Voltage Quality:** Excellent grid stability observed; zero sags or swells recorded, confirming full EN50160 compliance.\n*   **Operational Consistency:** The device remained in an ACTIVE state for all 1,333 readings, indicating continuous compressor operation during the observed period.","cached_at":"2026-09-08T16:01:42+05:00","expires_at":1788865602}
