Product code:
WM-E LCB NB
 

Central monitoring of street lighting operation, remote switching of lighting units – suitable for operating simultaneously 4 street lamp groups, even hundreds of lamps).

Our solution contains a switch box and a smart metering modem inside a coverage – as one device.
The product is capable of receiving the P1 customer interface data of WM-E3S® electricity metering modem. During the operation it counts the light switching, operation hours, by using daylight saving time, according the current time zone.

The device connects to the server via Narrow Band (NB-IoT LTE-M) network and serves the relay switch requests.
Switching can be remotely initiated from the centre on-demand or by scheduled intervals.
It also provides reports about daily events.

This is a cost-effective, safe, reliable and future-proof solution, which offers efficient central services. It represents low investment costs by decreasing operation outages, saving cost (by optimizing the lighting hours).

The Remote Device Manager® provides remote management & monitoring of devices for operating the street lighting network.
