5.6 tonnes of CO2
are emitted by the total consumption of electricity linked to street lighting in France every year.
can be achieved by switching off street lighting for just 2 hours a night.
in electricity consumption by local authorities since 2005, for a bill that has remained the same.
of light points are in France, i.e. one streetlight for every 6 inhabitants. 40% of them are already obsolete!
The benefits of connected street lighting :
Firstly, by connecting street lighting, local authorities can remotely modify the operating times of their public lighting systems directly via an Internet platform or an application.
Secondly, by configuring their lighting, local authorities can be alerted in the event of a fault, either by analyzing consumption or by issuing malfunction alerts, so they can act quickly and accordingly.
Finally, street lighting has an undeniable impact on biodiversity, altering natural cycles, biological rhythms and the physiological functions of living beings… Night-time shutdowns help minimize the impact of street lighting on biodiversity.

Can I use EPnrj without a Smart City strategy?
Of course! EPnrj is the ideal first step towards the Smart City. It's easy to set up, the effects are immediately visible and the benefits are rapid. Contact our experts for more information.
Can EPnrj be used to manage street lighting point by point?
Our teams are currently working on the point-by-point control of the public lighting system, in order to be even more precise about programming. For the time being, EPnrj allows you to control your street lighting network at the cabinet level, depending on how it is organized (e.g. district or street).
What type of cabinet does EPnrj fit into?
The EPnrj connected astronomical clock can be integrated into all types of public lighting cabinet. The timer controls the contactors already installed directly via dry contact.
What network does EPnrj run on?
EPnrj clocks communicate natively on Orange's LoRa network. Theoretical coverage areas in France can be found at https://www.orange-business.com/fr/reseau-iot.
Our teams are also working on an additional 4G modem that will enable EPnrj clocks to communicate over the GSM network.
How can I retrieve my consumption data?
EPnrj clocks are supplied with a cable to connect the clock to the Linky meter on the TIC output. Consumption data can then be viewed on the EPnrj web platform.
Is EPnrj compatible with other platforms or applications?
EPnrj is a hardware and software solution. Our teams have developed an API for sharing information with another platform (CMMS, hypervisor, etc.).
Is the EPnrj solution self-sufficient in the event of loss of network communication?
Yes, if the module no longer communicates on the selected communication network, the EPnrj clock operates autonomously according to the switching scenarios and exceptions programmed in the module.
