Eliminate perishable food stock loss, prevent catastrophic compressor seizures, and catch underground water leaks before they impact your balance sheet. SafeFile bridges long-range 868MHz LoRaWAN sensor telemetry directly into automated CMMS contractor dispatch—protecting your stores 24/7 with zero human intervention.
Engineered specifically for high-throughput commercial retail supermarket networks and enterprise retail portfolios where equipment downtime translates directly into inventory spoilage and municipal financial waste.
Continuous temperature and humidity tracking across butchery cold rooms (-2°C to 2°C), dairy chillers, and walk-in freezers (-25°C). Features Smart Defrost AI Suppression to eliminate false alarms during planned 45-minute defrost cycles.
Dual-channel pulse meter telemetry and floor rope leak sensors. Detects after-hours pipe bursts, continuously compares store consumption against municipal billing meters, and flags underground leaks costing upwards of R80,000/month.
Ultrasonic diesel tank fuel level monitoring, starter battery float voltage health, and Automatic Transfer Switch (ATS) failover verification. Guarantees your backup generator cranks up within 10 seconds of an Eskom / municipal grid drop.
Laser optical refrigerant leak detection for R404A, R507, R134a, and CO2 cascade systems. Generates court-admissible mass balance logs mandated by South Africa's Department of Forestry, Fisheries & the Environment (DFFE).
Tri-axial RMS velocity and acceleration monitoring on condenser fan motors, rack compressors, and butchery bandsaws. Detects rotor imbalance, misalignment, and bearing raceway spalling 14 to 21 days before catastrophic mechanical seizure.
Multi-parameter environmental monitoring (CO2 ppm, TVOC volatile organics, ambient temperature, and barometric pressure). Validates supermarket bakery oven exhaust ventilation, hot-deli smoke extraction, and store retail floor air changes.
Real-time telemetry stream from Central Regional Hypermarket (Store STR-0101) Dragino Gateway node.
Supermarket environments are notoriously hostile to conventional RF communications. Thick reinforced concrete floors, cold storage walk-in insulation, and steel refrigeration cases destroy Wi-Fi signals.
Operating on the statutory sub-GHz ISM band (868MHz for South Africa / Europe), LoRa signals penetrate multiple concrete barrier walls and double-skinned insulated cold room panels where 2.4GHz Wi-Fi attenuates instantly. A single Dragino DLOS8N outdoor gateway covers an entire 4,500m² supermarket footprint and outdoor condenser pads.
Unlike 4G/LTE cellular sensors that require 50 to 100 individual SIM subscriptions per store (costing R45 to R90/SIM/month), SafeFile’s LoRaWAN architecture uses a single secure private local gateway. 200+ wireless sensors communicate locally with $0 SIM carrier fees and up to 10-year internal lithium battery lifespans.
Guarantees zero database row inflation: Tier 1 updates a single in-place document per asset tag for real-time dashboards ($0 table growth); Tier 2 maintains a 72-hour rolling operational buffer pruned automatically; and Tier 3 hard-locks statutory breach records for 365 days for court-admissible audit proof.
Slide to specify your supermarket store network size and calculate the immediate annual financial savings delivered through automated cold-room protection, water leak detection, and predictive motor maintenance.
SafeFile integrates seamlessly with certified Dragino industrial LoRaWAN sensors. Each device arrives pre-configured with factory DevEUI / AppKey barcodes for 2-second smartphone QR binding in the SafeFile mobile app.
