Everything you need to know about home energy monitors

An energy monitor is a device that tracks and displays your household's energy consumption in real-time. It provides information on how much electricity different appliances and devices are using, allowing you to identify energy-hungry items and adjust your usage to save energy and reduce costs.

Energy monitors typically connect to your home's electrical panel or individual appliances to gather data and display it in a user-friendly format, such as through a mobile app or a dedicated display unit.

How does an energy monitor work?

Energy monitors work by measuring the electrical current flowing through the wires in your home. These monitors offer both immediate and historical data on electricity consumption, aiding users in understanding their power usage patterns.

Some advanced models can analyse these patterns to pinpoint which appliances are driving up energy costs. Additionally, monitors with access to your tariff details can estimate the cost of your electricity usage and alert you if you surpass a set usage threshold.

This feature is particularly useful for monitoring time-of-use tariffs, especially for identifying peak and off-peak periods. An overview of how they work:

  • A monitor is installed at your home's electrical panel, where it can measure the total electricity usage of your household.
  • It uses sensors to detect the magnetic field created by the electrical current flowing through the wires. By measuring this magnetic field, the monitor can determine how much electricity is being used.
  • An energy monitor then collects data on your electricity usage over time, typically in intervals ranging from a few seconds to a few minutes.
  • Energy data is displayed in a user-friendly format, such as on a digital display unit or through a mobile app. This allows you to see how much electricity you're using in real-time and track your usage over time.
  • Some energy monitors also provide analysis and insights into your electricity usage, such as identifying which appliances are using the most energy and how you can reduce your usage to save money.

Energy monitors are designed to help you become more aware of your electricity usage and empower you to make informed decisions to reduce your energy consumption and lower your electricity bills.

What are the benefits?

Using an energy monitor offers many benefits for managing electricity usage in your home. Here's how:

Tracking usage

With an energy monitor, you can easily track how much electricity you're using. This data helps you pinpoint areas where you can reduce usage and potentially save on your power bills.

Monitoring solar energy generation

If you have solar panels, an energy monitor can track how much energy your panels are generating, helping you maximise your solar investment.

Ranking high-use devices

Energy monitors can show you which devices in your home are using the most power. This information can help you make informed decisions about which appliances to replace or how to use them more efficiently.

Identifying usage patterns

By tracking your energy usage over time, you can identify patterns and habits that may be driving up your electricity costs. This awareness can lead to more energy-conscious behaviour.

It's important to note that while an energy monitor can provide valuable insights, it's up to you to make changes to your energy habits to see real savings on your bills.

Types of energy monitors

Energy monitors come in a range of styles to accommodate different budgets and lifestyles. Here are a few examples:

Wireless electricity monitors

These devices resemble tablets and communicate with sensors attached to your electricity meter. They provide real-time data on your energy usage.

Online electricity monitors

Similar to wireless monitors, these devices provide data through the internet or a smartphone app, eliminating the need for a separate display tablet.

Smart plugs

These plugs monitor the energy usage of individual appliances or power outlets. Some smart plugs also offer remote control via smartphone apps and require a suitable Wi-Fi connection.

The complexity of the installation can vary depending on the type of energy meter you have and the number of sensors needed for the energy monitor.

Energy monitors vs smart meters

A home energy monitor and a smart meter serve different purposes, though they both relate to monitoring and managing energy usage in the home.

Home energy monitor

  • Function: A home energy monitor is a device that provides real-time information about your home's energy consumption. It typically displays data such as current energy usage, costs, and sometimes even historical data.
  • Usage: Home energy monitors are typically used by homeowners who want to track their energy usage more closely to identify ways to reduce consumption and save money.
  • Installation: They are often installed by homeowners themselves and do not require any involvement from energy providers.

Smart meter

  • Function: A smart meter is a digital meter that records the amount of electricity and gas you use and communicates this information directly to your energy supplier for billing and monitoring purposes.
  • Usage: Smart meters are used by energy companies to accurately measure usage and bill customers accordingly. They also enable features like time-of-use pricing and remote meter readings.
  • Installation: Smart meters are typically installed by energy companies and are gradually replacing traditional meters in many regions.

While both devices provide information about energy usage, a home energy monitor is more focused on providing detailed real-time data for homeowners. A smart meter is primarily used by energy providers for billing and monitoring purposes.

Is it worth buying a home energy monitor?

Purchasing an energy monitor can be a worthwhile investment for many people. These devices provide valuable insights into your energy usage, helping you identify areas where you can reduce consumption and save money on your electricity bills.

By monitoring your energy usage in real-time, you can make more informed decisions about your energy usage habits and adjust them accordingly. Additionally, some energy monitors can also help you track the performance of your solar panels, if you have them installed.
