JENY is a lighting, signalling and event mast. It lights up at night, and it reacts to its day environment, either with bright animations, or by delivering messages that users can even send to it via their smartphone. Developed jointly with the manufacturer Technilum, fully programmable, it offers visibility to the smart city.

It is deployed on the park of Tremblay-en-France, as well as on the 20 ha of the new neighborhood of La Vallée in Chatenay-Malabry.
