Cold Storage Monitoring & Alerts

A single excursion costs thousands in spoiled product

Coolers and freezers fail without warning — compressor lockout, defrost cycle stuck, door left open overnight. By the time someone notices, the inventory is already at risk.

Manual temperature logs are unreliable and labor-intensive

Walking around to log each cooler temperature on a clipboard is hours per week, and produces gaps overnight and on weekends — exactly when failures happen.

No remote visibility across multiple locations

Multi-site operators (cold-storage chains, regional food processors, restaurant groups) have no single view of every walk-in across every facility.

Manual records fail inspections

FDA, HACCP, and USDA inspectors expect continuous temperature records with timestamps. Paper logs and spot-checks are not audit-grade.

On-edge monitoring that survives outages

A Raspberry Pi per facility reads every cooler and freezer probe locally and runs threshold logic on-device. Process control survives ISP outages, power flickers, and cloud incidents.

Multi-cooler, multi-location dashboard

See every walk-in, freezer, blast chiller, and controlled-atmosphere room across every facility on one screen. Sparkline trends per cooler. Grouped by location.

Threshold + door-open alerts before product spoils

Configure alert thresholds per cooler with hysteresis to avoid false positives. Anomaly detection flags compressor failures via rolling-baseline drift. Escalation chains wake the right person.

Continuous, audit-grade compliance records

Every reading is logged with a timestamp and exportable as a HACCP / FDA / USDA-style PDF report. Inspector-ready records, not clipboards.
