Street lighting
On a street lighting network, a failed luminaire is usually identified through a complaint, or during a night patrol survey. We connect each light point to the network, letting the fault report itself automatically and consumption stop being a single figure calculated at month end.

See this working in practice
A case built from the situations we see most often in this area, with the program working the way it would on your own site.
Situation
Faults are reported by residents
Maintenance is organised around the complaints that arrive and around night patrols, which are costly and slow. Weeks pass between the fault and the repair, and the stretch stays dark without the operator being aware of it.
At the same time, the bill arrives as a single figure per cabinet. There is no way to separate the consumption that corresponds to actual lighting from the part that comes from badly set schedules or equipment running in daylight.
What we measure
- Operating status of each luminaire
- Energy consumption per control cabinet and per circuit
- Running hours compared with the intended schedule
- Voltage and current at the cabinet, to catch faults before failure
- Opening of control cabinets
- Ambient light level, to govern switch-on
- And other quantities, depending on what your operation needs to track.
What you get
A concrete result for the team
Faults identified the same night
The luminaire that fails to light reports it automatically. The crew leaves with the list of points to replace instead of driving the route to find them.
Consumption per circuit
The bill now has a traceable source, which makes it possible to check that the schedule is actually being followed.
Remote control
Switching on, switching off and dimming are commanded per cabinet, with no site visit.
Coverage of the whole network
One gateway on a high point covers several kilometres of road, making it viable to connect stretches far from the centre.
One road or one district is enough to measure
A stretch of a few dozen luminaires is enough to validate network coverage and compare the number of faults detected with the number of complaints received over the same period.
