About the Client:
By the time the Client turned to SumatoSoft for software development assistance and guidance they had already developed and tested the required devices. They required an MVP to prove the feasibility to potential investors and an effective solution to future Clients.
- Location: London, UK
- Industry: Technological solutions / Food service
- Team size: 3 specialists (1 Project Manager, 2 Senior RoR Developers)
- Project duration: 12 weeks
Business challenge
The objectives of the project set for SumatoSoft team by the Client were the following:
- to plan, design and develop an MVP (minimum viable product) version of the solution;
- to prove the feasibility of the project to potential investors and demonstrate an effective solution to future Clients;
- to integrate the new application into the ecosystem of the Client’s existing solutions.
Additional requirements:
- develop administrative and end-user panels;
- implement features for monitoring, visualization of data; database management;
- provide integration with the data source;
- introduce AI & ML algorithms for anomaly detection.
Our solution
SumatoSoft developed an application equipped with the technological features needed for initial commercial use and gathering user feedback. The MVP version of the application provided a tool for data gathering and systematization along with a web panel for service administration and sensors setup and another for end-user interaction. Key integrations and functionalities included robust integration with Firebase as an external data source, extensive data visualization using a JS library, a custom system for roles administration offering extended permissions management, and machine learning capabilities for enhanced data analysis.
Custom administration system
The administration system features an intricate roles setup with granular permissions, allowing for detailed management and control over the IoT monitoring system and its users.
Additional features:
- real-time monitoring of refrigerators;
- anomaly detection with instant alerts;
- maintenance notifications;
- interactive dashboards for historical data analysis.
Business value
Before:
- No central system for monitoring commercial refrigerators across HoReCa venues
- No preventive maintenance in place – refrigerator failures were detected only after occurring
- No investor-ready product to demonstrate the solution’s commercial potential
- Device operated in isolation with no integration into the Client’s existing systems
After:
- Centralized IoT dashboard with real-time monitoring of all commercial refrigerators, reducing undetected failures and cutting refrigerator-related food spoilage by ~25%
- Real-time anomaly detection and proactive maintenance alerts cut emergency maintenance calls by ~40% and minimize unplanned venue downtime
- MVP successfully validated with investors and existing customers, generating first purchase orders immediately after the initial demonstration
- Application integrated with the Client’s device ecosystem, with HACCP-compliant automated temperature logging eliminating manual compliance record-keeping
