Join us in transforming the future of energy. With our advanced technology, we are making smart metering and smart grid applications more efficient, reliable, and sustainable. Together, we can build a smarter, greener, and more resilient energy infrastructure for generations to come.
Smart metering is crucial not only for billing purposes, but most importantly to gain actionable insight about the demand on the grid in order to be able to balance it better with supply. Smart metering begins with communication devices that collect and send data to a central management planform. Today, cellular IoT technologies such as NB-IoT and Cat-M1 allow massive smart metering systems to operate reliably and cost efficiently.
We offer cellular IoT communication devices for smart metering solutions: modems and routers allow for Automated Meter Reading (AMR) of electricity and water meters!
You can also build infrastructure – by combining with our data concentrators, routers – to collect and send data to the central head-end-system (HES) or a database.
Our modems were specifically designed for the electricity meters of large manufacturers (such as Elster®, Honeywell®, Itron®, Landis+Gyr®, PME-PMI®, Saphir®, Iskra®, EMH®, AECL® and Kamstrup®). These modems are at the heart of AMI (Advanced Metering Infrastructure) of public utility companies.
The modems connect to the meters, read the consumption data (through RS232/RS485), and send them to the data center via cellular networks, while providing remote access and monitoring features for the head-end systems. Features include transparent push data sending, pull on-demand requests, scheduled readouts, and meter data downloads, and more.
Some of our modems support the multi-meter connection, allowing to connect multiple meters to one modem.
The meters are connected via RS485 and the modem sends the data from a single “master” meter.
This is a cost-effective solution when implementing an automated energy metering system. Discover our electricity metering modem product families:

One of the main challenges water companies face today is what the industry calls Non-Revenue Water, the quantity of water lost due leakage and theft.
The right information at the right time enables the right decisions. Digitalisation and intelligent use of data make it possible to improve operational efficiency as never before.
We solve the limitations of network construction in legacy two-hop networks LoRa or RF. These traditional technologies operate on unlicensed spectrum, which may cause channel interference among different applications, such as water, electricity metering or public street lighting.
NB-IoT offers deep coverage and massive connections with low power consumption. It is an ideal network communications technology for the smart water solution.
Our data logger receives pulse signals, Mbus data simultaneously and periodically sends them to the data center on the NB-IoT / Cat.M network. The device is powered by a long-life battery solution.
It supports the modern IoT transportation protocols such as the MQTT and LwM2M.
Our Device Manager software adds true value to any smart water metering solution. Using a Windows-based remote device management platform, you have continuous access to your devices.
Streetlights are a proven way to reduce crime and accidents, but those benefits come at a steep price. According to the World Bank, in some cities, streetlights use so much electricity they consume up to 20% of municipal budgets.
Many cities have replaced their metal halide and high-pressure sodium streetlights with LEDs, which are 40% to 60% more energy-efficient, to save money. Higher efficiency also helps cities meet green goals like reduced CO2 emissions.
Now cities are turning to Internet of Things (IoT) technology to take those benefits to the next level. IoT enables “smart streetlights” that use sensors to increase their brightness automatically when vehicles and pedestrians are nearby. For example, smart streetlights can use IoT to connect to a city’s existing video surveillance cameras to detect pedestrians. IoT also enables centralized management, such as turning up the brightness for all streetlights on the blocks surrounding an arena as a game ends.
These kinds of IoT-powered capabilities save far more electricity than traditional methods such as timers — or leaving streetlights at the same brightness all the time. They also reduce light pollution, which disrupts the circadian rhythms of people living in cities and suburbs. No wonder that the global installed base of smart streetlights has a compound annual growth rate (CAGR) of 24.5%, according to Berg Insight.
Obviously, it is connectivity that makes smart street lighting smart. Most legacy smart public lighting systems using PLC / Mesh communications suffer from latency, manageability and other issues. Cellular technologies, such as LTE, 5G, and NB-IoT are ideal for smart street light monitoring, control and management.
For basic smart lighting service, which generates small amounts of data, the best communication technologies are the two emerging cellular-based IoT standards, NarrowBand-IoT (NB-IoT) and Long-Term Evolution (LTE)-Cat-M1, which have been designed to implement Low-Power Wide-Area Networks (LPWANs).
Our devices are at the heart of flexible public lighting services, providing an internet-based bi-directional communication based on the Open Smart Grid Platform. They allow the automation of basic lighting controls such as switching on/off based on a programmable schedule, dimming, failure detection, and monitoring lamps status and consumption (e.g.: voltage, current and power factor).
Applications
- Electricity providers
- Public lighting operators
Load management solutions have a vital role in the smart grid of the future. They allow us to use pre-defined control strategies to remotely optimize water heaters, electricity chargers, heat pumps, and HVAC systems during periods of high demand in order to balance resources. Effective load management strategies allow utilities to avoid black-outs and consumers to save on electricity bills.
Legacy load management systems provide only 1-way communication, which means there is no confirmation that the device has received the message and executed the instructions properly. While these systems did manage to optimize costs during peak demand and prevent outages, today’s advanced grid management tasks need bi-directional communication, almost real-time load data, high availability, and reliability.
Using the latest cellular communication technologies, our products help automate load control management to allow better demand response for utilities and municipalities.
