Improving IoT lighting system with tens of thousands units on the city scale

Industry: IoT, Smart City
Location: Denmark


Novalume is an international company that develops and manufactures advanced energy-efficient LED lighting solutions for smart cities. The client has turned to Euristiq for support and improvement of an existing IoT smart city lighting solution for lamp control units which are installed in several cities. It was a high concurrent, heavily loaded network, several parts of which have already been working for years and were sensitive to changes in the firmware.

Scalable high-performance smart city lighting solutions to control 2M street lamps all over the world

The Novalume has turned to Euristiq for support and improvement of an existing IoT lighting system – a high concurrent, heavily loaded network, several parts of which were sensitive to changes in the firmware.

A mobile application for manufacturers that Novalume envisioned, could scan components being assembled into the asset and automatically sync scanned data with the server. One platform had to support multiple customers, who each could control, view, and manage their city luminaire setup.

The new IoT smart city lighting system had to collect and store vast amounts of metric data and control ~2m city lamps all over the world. Solution’s requirements included high-performance of a product, its usability, reliability, security, and scalability, backward compatibility. In addition to the development of new firmware, new hardware modules had to be integrated into the next generation of the system. The plugin system had to connect multiple device vendors.


An intelligent control and maintenance system that optimizes street light usage

Novalume engaged Euristiq for the development of LUMINTELL™, an IoT application that comes in three forms: an admin website, a client website, and an Android application.

After evaluating the needs of the system, Euristiq’s team decided on a technical stack and began the IoT software development process for the smart lighting system which included architecture engineering, UI/UX design and frontend/backend development.

The product, IoT system called LUMINTELL™, optimizes street light usage to lower energy consumption by decreasing the lighting level during off-peak traffic hours. Many features are available at the click of a mouse, like real-time monitoring and performance reporting, all without compromising quality or safety.

The software allows visualizing entire street light installations and monitoring their operations. Also, users can evaluate the consumption and intensity of the light emitted from the luminaire, individually or in groups. Luminaire parameters can be adjusted in real-time, without any additional costs towards increasing their lifetime.


Real-time monitoring and reporting of performance reduces maintenance costs by up to 75%

Euristiq with a performance team of 6 engineers improved IoT smart city lighting solution with several hundred units in the mesh network and tens of thousands of units on the city scale. System security was also improved through device and communication channel protection and optimized traffic between the network coordinator and the back-end server.

Via real-time monitoring and performance reporting, the smart city lighting solution allows reducing maintenance costs by up to 75% and the reduction of CO2 emissions.
