Business challenges

Managing a global fleet of IoT-enabled refrigeration units

Due North needed a connected smart refrigeration system to upload telemetry and alerts in real time, enabling remote monitoring and configuration to improve operations and reduce downtime.

The challenge was to build a secure, scalable IoT platform capable of supporting hundreds of thousands of connected devices globally. They also required a multi-interface solution, with a mobile app for store managers to monitor individual units and a web portal for administrators to manage customer fleets.

The platform also needed intelligent alerting, remote diagnostics, firmware updates, and multi-language AI-powered analytics for efficient asset management.

Solution

A scalable AWS IoT platform in just 9 months

Firemind designed and implemented an enterprise-grade IoT data platform on AWS, enabling real-time telemetry ingestion, data processing, and remote device management.

Using AWS IoT Core, the system securely connects smart fridges to the cloud, allowing real-time monitoring and remote configuration. Amazon S3 and Amazon Redshift handle large-scale data storage and analytics, ensuring optimised performance across thousands of devices.

The solution includes a mobile-first app for store managers to monitor and control individual fridges and a web-based admin portal for managing customer fleets, device configurations, and firmware updates at scale.

Built for scalability, the platform has been successfully tested with 100,000 devices and is designed to support over 1 million smart refrigeration units globally. Future enhancements will include AI-driven analytics and image-based processing for advanced monitoring.

Real-time alerts & AI monitoring

The platform detects door open, temperature spikes, and system failures, instantly notifying users via email, SMS, and app notifications.

Scalable to 1M+ devices

With AWS’s serverless and event-driven architecture, the platform seamlessly scales from 100,000 to over 1 million devices with minimal latency.

Multi-language GenAI

Enables smart fridge control through natural language commands in English, French, and Spanish, allowing users to monitor and adjust settings seamlessly.
