The Challenge

Flipkart Minutes delivers groceries and frozen/chilled food to customers in 10-15 minutes. Maintaining cold chain integrity from sourcing hub to delivery is critical for food safety and customer trust. Their operations faced several challenges:

  • No visibility into freezer/chiller conditions—manual temperature logging prone to errors and delays
  • Compliance risk—inability to prove continuous cold chain maintenance for food safety audits
  • Door left open incidents—freezers and chillers left open, leading to temperature excursions and product spoilage
  • Reactive problem detection—finding out about temperature failures after product damage
  • Complex wiring requirements—traditional wired sensors difficult and expensive to deploy across distributed dark stores
  • No visibility during transit—temperature-controlled stock transfers between hubs and stores lacked monitoring
  • Network dependency—internet outages meant loss of critical temperature data
  • Alert fatigue—too many false alarms making it hard to identify real issues

Flipkart needed a cold chain monitoring solution that was simple to deploy, worked offline, and provided intelligent alerts to prevent product spoilage and ensure food safety compliance.

The IoTReady Solution

Comprehensive cold chain monitoring with BLE sensors, offline capabilities, and intelligent alerting

1. Multi-Zone Environmental Monitoring

Real-time temperature and humidity tracking across all storage zones:

  • Freezer zones—continuous monitoring of -16°C to -22°C storage areas
  • Chiller zones—2°C to 8°C monitoring for dairy, produce, and beverages
  • Tropical zones—ambient temperature tracking for dry goods and packaged items
  • Door sensors—detect when freezer/chiller doors are left open, triggering immediate alerts
  • Humidity monitoring—prevent condensation and moisture-related spoilage

2. Wireless BLE Sensor Deployment

Battery-powered BLE sensors for simple, wire-free installation:

  • No wiring required—battery-powered sensors run for months without replacement
  • 30-meter range in clear line of sight—strategically position gateways to cover entire facility
  • 10-meter range inside metal enclosures—reliable monitoring even inside freezers and chillers
  • Quick deployment—install sensors in minutes, not hours
  • Low maintenance—minimal battery replacements, no ongoing infrastructure costs
  • Flexible placement—easily reposition sensors as storage layouts change

3. Local Display & Audible Alarms

Immediate on-site visibility and alerts:

  • Real-time local display—show current temperatures on screens at each dark store
  • Audible alarms—triggered by remote business rules when thresholds are breached
  • Instant operator feedback—workers immediately aware of temperature issues
  • Remote business rule updates—change thresholds and alert logic without site visits

4. Offline Capabilities

Continue monitoring even when internet connectivity is lost:

  • Local data storage—gateway caches temperature readings during network outages
  • Auto-sync when online—data automatically uploads when connectivity restores
  • No data loss—complete cold chain record even with intermittent internet
  • Local alarms work offline—audible alerts function without cloud connectivity

5. Temperature-Controlled Stock Transfers

Monitor cold chain integrity during transit:

  • At least 1 sensor per temperature zone—separate monitoring for freezer and chiller compartments in vehicles
  • Offline temperature capture—BLE sensors record data throughout transit without network dependency
  • Receipt validation—scan sensors at destination to verify cold chain maintenance during transfer
  • Transfer audit trail—complete temperature history from dispatch to receipt
  • Reject at receipt—refuse stock transfers that violated temperature requirements

6. Flexible Gateway Options

Works with existing hardware or IoTReady gateways:

  • IoTReady gateways—WiFi, Ethernet, or 4G connectivity options
  • Android phone/tablet—use existing devices as BLE gateways
  • No vendor lock-in—flexibility to use customer's existing hardware
  • Scalable deployment—add gateways as needed without infrastructure overhaul

7. Centralized Business Intelligence Dashboard

Real-time visibility across all locations:

  • Multi-location dashboard—view temperature across all sourcing hubs and dark stores
  • Historical data—trend analysis and compliance reporting
  • Excursion reports—identify when and where temperature violations occurred
  • Downtime alerts—gateway or sensor offline notifications
  • Compliance exports—download temperature logs for food safety audits

8. Multi-Channel Notifications

Alerts delivered wherever your team is:

  • SMS alerts—critical temperature excursions sent via text message
  • Email notifications—detailed reports to operations managers
  • In-app notifications—push alerts to mobile app users
  • Escalation rules—automatic escalation if initial alerts are not acknowledged
  • Role-based routing—different alert recipients for different locations and zones

9. Intelligent Alerting with AI

Reduce alert fatigue with anomaly detection and pattern recognition:

  • Anomaly detection—identify unusual temperature patterns that indicate equipment issues
  • Pattern recognition—learn normal operational patterns (door open for restocking) vs. real problems
  • Predictive alerts—warn about potential failures before critical thresholds are breached
  • Smart thresholds—dynamic alerting based on time of day and operational context
  • Fewer false alarms—intelligent filtering reduces alert fatigue and improves response times
