Hugo Morlet, the developer behind LEDoMATIC

A project born from Île-de-France Mobilités open data
It all started as a small personal project, just for the fun of coding. Hugo was playing with the open data published by Île-de-France Mobilités, the Paris region transport authority: lines, stops and, above all, real-time waiting times for metros, RER trains, trams and buses. He programmed a small screen showing the next departures from his station, borrowing the look of the Paris metro signs.

Videos that went viral on social media
Hugo shared his first prototypes in videos on social media. The videos went viral and messages poured in, almost always with the same question: “Where can I buy one?”

The birth of LEDoMATIC
To meet this demand, Hugo created LEDoMATIC, a brand of original connected devices designed and handmade in France. Each waiting-time display is assembled, programmed and tested one by one before shipping. Beyond Paris, LEDoMATIC now works in many cities across France and Europe.
