The client is one of the largest electronics companies in the world, with one of the divisions specialized in lighting. This enterprise turned to Euristiq with a smart city lighting concept.
For this R&D project, the purpose of street lighting was to create a special atmosphere in certain areas of the city, for instance, smart colorful illumination of historic sights, parks, squares, etc. This had to be achieved utilizing special hue smart light bulbs manufactured by the client.
The result of our collaboration is an IoT system based on the energy-efficient LED street lighting. The system allows lighting operators to control city lighting remotely via a mobile app.
Euristiq team developed a system’s backend application that is deployed on Raspberry PI and a mobile Android application for lighting operators.
Users can change lighting settings and schedule changes of lighting color in an app. These user actions are stored in the cloud (Google Firebase). Our Java backend application listens to the events (user actions) stored in Google Firebase and via HTTP protocol sends them to an application developed by the client (deCONZ) which is also deployed on Raspberry PI. It further communicates with the lighting hardware using a wireless Zigbee connection. Upon obtaining a signal, light bulbs behave accordingly – change their hue, brightness, or switch on/off. Our backend app also sends signals to groups of lamps to check whether they are in working condition.
