Product code:

Central monitoring of street lighting operations, switching of lighting units remotely – suitable for simultaneous operating of 4 street lamp groups, i.e. 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 to the current time zone.

The device connects via CDMA 450 / 2G / 3G / LTE 4G / LTE-M & Narrow Band networks to the server and serves the relay switch requests.
The switching can be initiated remotely from the centre on-demand or by scheduled intervals.
It also provides reports from the daily events.

It constitutes a cost-effective, safe, reliable and future-proof solution, which offers efficient central services. It assures 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.
