IoT and energy efficiency: how to optimize consumption with connected devices

Energy consumption has become a priority for companies, utilities, building managers, industries, and public administrations. Reducing costs, improving sustainability, and having reliable data on energy use requires measuring, analysing, and acting on consumption in real time.

This is where IoT plays a key role. By connecting sensors, smart meters, machines, HVAC systems, charging points, or solar installations, organisations can transform scattered energy data into useful information to make better decisions. At 1NCE, we understand IoT connectivity as an essential component for ensuring these projects can be deployed reliably, scalably, and over long periods.

What is the connection between IoT and energy efficiency?

The Internet of Things, or IoT, refers to a network of connected physical devices that collect, transmit, and, in many cases, process data. In the energy sector, these devices can include smart meters, sensors for temperature, humidity, occupancy, pressure, flow, air quality, electricity consumption, or machinery status.

When applied to energy efficiency, IoT enables a shift from management based on estimates or periodic readings to management based on continuous data. This means a building can adjust its HVAC system according to real occupancy, a factory can detect unusual consumption patterns, and a utility can collect data from smart meters without manual readings.

At 1NCE, we see this connection particularly in projects related to smart metering, energy management, industry, electric mobility, smart buildings, and energy asset monitoring.

How does IoT help monitor and optimize energy consumption?

Monitoring is the first step towards improving energy efficiency. IoT devices make it possible to collect data on the consumption and performance of equipment, facilities, or energy networks, and send it to analytics platforms, energy management systems, maintenance applications, or billing solutions.

This visibility helps detect consumption peaks, energy use outside operating hours, equipment performing above expected levels, or facilities that are not working as efficiently as they should. IoT data can also be used to automate systems, anticipate failures through predictive maintenance, and manage energy demand more effectively.

In smart metering projects, our IoT connectivity makes it possible to transmit data from smart meters remotely. This helps utilities, energy operators, and solution providers reduce manual readings, improve data availability, and scale deployments with thousands or even millions of connected devices.

What role do sensors and smart meters play?

Sensors and smart meters are an essential part of IoT projects focused on energy efficiency. Their role is to capture data from the environment, consumption, or equipment status, and transmit it to systems where it can be analysed.

At this point, 1NCE provides the connectivity layer that allows this data to travel from the device to the platform, even when equipment is distributed across multiple locations or cannot rely on local networks such as WiFi or Ethernet.

Use cases of IoT in energy efficiency

IoT-based solutions can be applied in many different environments, from energy networks to buildings, factories, solar installations, and charging points. In all these cases, 1NCE connectivity enables data transmission from sensors, meters, and connected devices, helping improve monitoring, automation, and decision-making.

• Smart metering and utilities

Smart meters make it possible to collect consumption data remotely, reduce manual readings, and improve billing accuracy. With 1NCE IoT connectivity, utilities and energy providers can deploy connected devices at scale without relying on the end user’s local connection.

• Energy monitoring in buildings and industry

IoT sensors help monitor HVAC, lighting, ventilation, machinery, production lines, and consumption by area. This data makes it possible to detect deviations, reduce unnecessary energy use, and improve operational efficiency.

• Solar energy and electric vehicle charging

Solar installations, self-consumption systems, and charging points create new energy management scenarios. IoT makes it possible to monitor production, availability, charging, and energy flows, while 1NCE cellular connectivity helps ensure stable and scalable data transmission.

Why is connectivity key in energy efficiency IoT projects?

Connectivity is one of the foundations of any IoT solution. Without reliable data transmission, sensors, meters, and connected devices lose much of their value.

In energy efficiency projects, devices are often deployed in homes, buildings, factories, technical rooms, distribution networks, solar installations, charging points, or remote locations. That is why connectivity needs to offer coverage, reliability, low power consumption, scalability, remote management, and compatibility with technologies such as 2G, 3G, 4G, LTE-M, or NB-IoT, depending on the use case.

At 1NCE, we offer IoT connectivity designed for long-term deployments, with simple management and coverage ready for international projects. This is especially relevant for companies that need to keep devices connected for years, with limited maintenance and without always depending on the customer’s local infrastructure.

Use Cases and Real-World Examples

In the energy sector, IoT plays a key role by connecting meters, infrastructure and monitoring systems to collect real-time data and improve visibility into energy consumption, production and performance. This type of connectivity is especially valuable in areas such as smart metering, distributed energy management and remote asset monitoring.

Real-world use cases help show how this technology is applied across different energy, utilities, and smart metering scenarios:

• Xemex, a specialist in smart energy communication, uses IoT connectivity to transmit meter readings and monitor energy flows for grid operators, electric vehicle charging, solar installations, home energy management, and submetering.

• Hildebrand applies IoT to smart energy management through metering solutions that provide a clearer understanding of electricity consumption in homes, offices, and other connected environments.

• Cast4All develops energy monitoring solutions for residential solar installations, buildings, and data centers, enabling continuous tracking of energy performance.

• Lobaro works on smart metering and remote reading projects for utilities and industry, with IoT solutions designed to digitize meters and collect data efficiently.

• Società Impianti Metano uses IoT connectivity to deploy smart gas meters, enabling remote reading and more efficient management of the distribution infrastructure.
