{"response":"### Energy Status Summary: Main Refrigerator\n\n**1. Overall Status**\nThe unit is operational and stable, consuming 98.98 kWh over 7.9 days at an average load of 565.11W, with a total estimated operational cost of approximately 10,888 PKR.\n\n**2. Key Metrics**\n*   **Power:** Current draw is 524.4W (avg: 565.11W; peak: 2562.4W).\n*   **Voltage:** Stable at 236.8V (avg: 234.66V), remaining well within the 230V nominal range.\n*   **Efficiency:** Power Factor (PF) is low at 0.67 (avg: 0.71), indicating inefficient electrical utilization.\n*   **Reliability:** 100% EN50160 compliance with zero voltage sags or swells.\n\n**3. Notable Observations**\n*   **Efficiency Concern:** The low average PF (0.71) suggests the compressor or motor may be aging or poorly maintained, leading to higher reactive power losses.\n*   **Overload Frequency:** There are 281 \"OVERLOAD\" readings recorded. While the unit is currently stable, the high peak power (2562.4W) compared to the average suggests frequent high-draw startup cycles or potential cooling system strain. \n*   **Availability:** The refrigerator is almost constantly active, with only 9 readings recorded in an \"OFF\" state over the 8-day period.","cached_at":"2026-07-16T11:06:47+05:00","expires_at":1784182307}
