The difference between traditional meters and smart meters
Traditional energy meters, typically located on the premises, are mechanical devices that log the electricity consumption in your household for billing purposes. The data collection process for these devices necessitates a utility company representative to physically read and record the meter's information during each billing cycle.
In stark contrast, smart meters redefine this approach. These digital devices continuously measure and record energy consumption in real time and relay this data remotely to the utility provider. By eliminating the need for manual readings, smart meters facilitate more accurate and prompt billing. But the benefits extend beyond billing&#;smart meters offer real-time energy consumption monitoring and immediate reporting of power outages.
The prevalence of smart meters
As reported by the Institute for Electric Innovation, the deployment of smart meters is rapidly increasing. By the end of , an estimated 107 million smart meters had been installed across the US, and this number continues to grow.
The integration of smart meters into the IoT ecosystem represents more than a fleeting trend. In the words of the Institute for Electric Innovation,
"Smart meters are the 'fundamental building block' for an evolving distribution grid."
This integration is a significant milestone in the journey towards the future of energy.
How do smart meters work?
So, how do smart meters work? The crux of a smart meter's operation lies in its capacity to communicate. Smart meters measure energy consumption like traditional meters. However, they also have a two-way communication system. This system allows them to send consumption data to the utility provider. It also allows them to receive instructions or updates from the provider.
How do smart meters communicate?
A variety of communication technologies, including cellular networks, power line communication (PLC), or radio frequency (RF) mesh networks, enable smart meters to communicate. These communication protocols facilitate the seamless integration of smart meters into the expansive IoT ecosystem.
Given that smart meters handle sensitive information, security is an understandable concern. Therefore, these devices are designed with multiple layers of security protocols, including encryption and strict access controls, to protect user data. However, they are not immune to threats, emphasizing the necessity of ongoing smart meter security enhancement.
Use cases of smart meters
Improved transparency and fair cost distribution in apartments
Multi-tenant dwellings, like apartment blocks, benefit from the real-time data provided by smart meters. In the past, tenants would divide costs annually, which usually resulted in energy expenses being distributed unfairly or incorrectly. Tenants were also left in the dark about their energy consumption until their bill arrived, making it challenging to manage and reduce their usage.
Smart meters have made it possible for tenants to manage their energy consumption and understand their usage patterns. This increased transparency makes fair distribution of energy costs possible as people can be charged for their actual consumption.
Demand response programs
One significant application of smart meters is their role in enabling demand response programs. These programs incentivize consumers to reduce their energy usage during peak times in exchange for cost savings on their energy bills.
Smart meters facilitate these initiatives by providing real-time data on energy usage, allowing utility providers to monitor and control energy demand more effectively. This not only aids in managing the energy grid more efficiently but also empowers consumers to make informed decisions about their energy usage, contributing to overall energy conservation.
Energy/Solar panels
A third application of smart meters lies in the context of renewable energy, particularly solar panels. As sustainable energy solutions gain traction, smart meters enhance the efficacy of solar energy systems by providing real-time data on both energy usage and solar power generation. This enables homeowners to maximize their solar power utilization, adjust consumption patterns, and potentially reduce their overall energy costs.
During peak production times, solar panels often generate excess energy which is fed back into the grid. Smart meters not only record this surplus but also communicate it to utility providers. This can result in homeowners receiving credits for the excess power their solar panels have produced, contributing to significant cost savings.

What Is Smart Metering?
Smart Metering is a technique of digitizing the energy system using smart meters that provides businesses a way to track how much energy they are using so that they can adjust the usage when required.
A Smart Meter is an intelligent digital device that is designed to replace the traditional electricity and gas meter. It can be equipped with a display screen that shows the exact energy usage in real-time. Installing a smart meter helps you get rid of estimated bills by allowing you to control and reduce energy consumption.
It comes with the functionality that allows sending meter readings to energy suppliers and gathering information remotely. Smart cities can leverage smart meters to collect data that provides insights on infrastructure, public services, and population.
The typical challenge for companies implementing smart meters is how to integrate them within their infrastructure and organize custom smart metering use cases. Here is when IoT comes into the picture.
The best way to integrate smart meters within its infrastructure is by using an IoT platform that comes with data processing capabilities. It will not only allow you to collect data from smart meters but can also help you set up custom visualization dashboards.
How does IoT-enabled Smart Meter work?
A smart meter works, depending on its functionality, whether it is used for measuring electricity or gas. IoT-enabled smart meter uses features of embedded systems, i.e., a combination of software or hardware.
To install a smart meter, there is no need to replace the existing energy meter. Instead, a small modification is done on the already installed meters to convert them into smart meters.
We shall explain the working of a smart meter that uses the ESP Wi-Fi module and Arduino that cannot only send you the notification but also monitor energy uses. ACS712 current sensor can be used to measure energy consumption.
Following are some of the components that can be used in the working of a smart meter:
- Arduino UNO
- ACS712-30 Amp Current Sensor
- ESP12/NodeMCU
- Male-Female Wires
ACS712 sensor works on the principle of Hall-effect and is used to measure the magnetic field around a conductor carrying current. It can measure both DC and AC and provides the separation between the measuring unit and the load.
Arduino can read the current sensor value via analog pin and transfer it to the Wi-Fi module with serial communication. MQTT broker can be used to monitor energy uses over the internet.
The smart meter reading is generated 24*7 in real-time and is sent to the edge of the network where edge computing can be applied to implement business logic for the data captured by a meter. For example, the cost of electricity can be calculated in real-time.
Consumers can set a threshold value for electricity units. Logic can be implemented to turn off the meter automatically if it crosses the threshold amount set by the consumer. If a user increases the threshold value, the meter can automatically turn on. Therefore, smart meters can also be used for the better conservation of electricity.
What are the benefits of Smart Metering?
Smart Meters provide you an understanding of how you utilize the energy. Smart meters come with an in-house display that lets you track energy when you are using devices. It helps you see in real-time if the changes you have made for better energy consumption is really working or not.
