Smart meter monitor: understanding your energy use

A smart meter monitor, commonly known as an In-Home Display (IHD), puts your energy usage data directly into your hands. It helps you understand and manage your household's electricity and gas consumption. These devices are designed to demystify your energy use, showing you in near real-time how much power you are consuming and what it is costing you. By making energy visible, IHDs provide a foundational tool for taking control of your bills and identifying opportunities to reduce waste.

Managing your energy should be straightforward and clear. Fuse Energy offers transparent pricing and real-time usage data through its app, helping you stay on top of your household's energy consumption. Click here to switch to Fuse Energy today.

What is a smart meter monitor (In-Home Display)?

An In-Home Display (IHD) is a small, portable screen that connects wirelessly to your smart electricity and gas meters. It provides a user-friendly interface to view your energy consumption data in an accessible format. Energy suppliers typically provide IHDs free of charge as part of a smart meter installation, though availability is not guaranteed.

What an In-Home Display shows

Your IHD displays key information about your energy use, usually in pounds and pence, as well as kilowatt-hours (kWh). For electricity, this data updates in near real-time, while gas usage typically updates less frequently. This allows you to see how much energy you are using at any given moment, helping you to make informed decisions about your consumption. Some IHDs can also show your remaining credit if your smart meter is in prepayment mode.

How smart meters and IHDs communicate

Smart meters send your energy usage data automatically over a secure wireless network to your IHD. This connection often uses a Home Area Network (HAN), a local radio link between your meter and the display. The smart meter itself also sends readings directly to your energy supplier, ensuring accurate billing without manual submissions.

Benefits of using a smart meter monitor

Using a smart meter monitor offers several advantages for managing your home energy.

Understanding your energy usage

An IHD provides a clear, immediate picture of your energy consumption, allowing you to see how much electricity and gas you are using as it happens. This visibility helps you become more aware of your energy habits and how different appliances contribute to your overall usage.

Identifying energy-saving opportunities

By tracking your energy patterns, you can easily spot areas where you might be wasting energy. For example, if you notice a spike in usage at certain times, you can investigate which appliances are responsible and adjust your habits accordingly. This insight is crucial for making small changes that can lead to significant savings over time. You can find more tips on how to reduce your energy consumption in our guide to energy-saving tips.

Managing your budget

Seeing your energy use in pounds and pence helps you keep a closer eye on your spending. This real-time cost information allows you to manage your budget more effectively and avoid unexpected high bills.

Common issues with smart meter monitors and how to solve them

While IHDs are useful, they can sometimes encounter issues. Most problems have straightforward solutions.

Blank screen or no data

A blank screen is a common complaint. Often, this is due to a power or battery issue. Ensure your IHD is properly powered. If it runs on battery, allow it to charge for a period before trying to switch it on again. If the screen is on but shows no data, it might be a connectivity problem.

Connectivity problems

If your IHD is not displaying data, it could be too far from your smart meter or there might be thick walls blocking the signal. Try moving the IHD closer to the meter, ideally within a few metres with as few obstructions as possible. Sometimes, simply turning the IHD off and on again can re-establish the connection. If the issue persists, your energy supplier may be able to reset the connection remotely.

Outdated or inaccurate readings

If your IHD shows incorrect costs or tariff information, it means the tariff data has not been updated. While the meter itself will still bill correctly, this makes the IHD less useful for tracking spending. Contact your supplier and ask them to update the tariff information on your meter. Issues can sometimes arise if your smart meter's communication hub has a problem or if you have an older SMETS1 smart meter that has lost some functionality after switching suppliers.

Radio Teleswitch (RTS) meters

The Radio Teleswitch Service (RTS) is a legacy technology that used longwave radio signals to switch between peak and off-peak electricity rates. The RTS signal is being phased out, with the industry-wide switch-off beginning on 30 June 2025. If you still have an RTS meter, your heating and hot water supply may be affected, and your electricity costs could be higher if your supplier cannot confirm your usage during different rate periods.

If you have an RTS meter, your current energy supplier must replace it with a smart meter. This upgrade is free of charge. Once your meter has been replaced, you can then switch to a modern energy supplier like Fuse Energy to benefit from the latest smart meter technology and a digital-first experience.

Beyond the IHD: digital alternatives for energy monitoring

While physical IHDs offer valuable insights, digital energy apps can provide a more comprehensive and flexible monitoring experience.

The advantages of energy apps

Energy apps, like the Fuse Energy app, transform your smartphone into a sophisticated smart meter monitor. They offer the same real-time usage data as an IHD but with added functionalities such as historical insights, detailed breakdowns, and integration with your energy account. This digital approach overcomes common IHD limitations like physical breakage, limited functionality, or connectivity issues specific to a single device.

Real-time data and historical insights

Digital apps provide not only real-time energy consumption in kWh and pounds and pence, but also allow you to view your usage patterns over days, weeks, and months. This historical data helps you identify long-term trends, compare consumption periods, and understand the impact of energy-saving measures.

Seamless integration with your energy supplier

A dedicated energy app from your supplier offers a unified experience. It integrates your energy monitoring with your billing, tariff information, and customer support, all in one place. This means you can manage your account, view your usage, and get help if needed, directly from your phone. Smart meters enable automated readings and eligibility for smart-meter-dependent tariff features. For more information on how to check your meter, read our guide on how to read your smart meter.

Maximising your savings with smart meter data

Understanding your energy data is the first step towards significant savings and more effective energy management.

Making informed decisions

With clear data from your smart meter monitor, you can make informed choices about when and how you use energy. The average UK home uses around 2,500 kWh of electricity per year, a figure set by Ofgem's medium Typical Domestic Consumption Value (TDCV) effective from 1 July 2026. Understanding your own usage against this benchmark helps you identify areas for improvement. This knowledge empowers you to adjust your habits, such as running high-energy appliances during off-peak hours if you are on a time-of-use tariff.

Optimising appliance use

By observing real-time data, you can pinpoint which appliances consume the most energy. This allows you to prioritise efficiency upgrades or change how you use particular devices. For instance, you might discover that an old appliance is a significant energy drain and decide to replace it with a more efficient model.

Future-proofing your energy management

Digital energy monitoring tools provide the foundation for advanced energy management. They allow you to track the effectiveness of any changes you make, from insulating your home to installing energy-efficient lighting. This continuous feedback loop ensures you stay in control of your energy consumption and costs, adapting to new tariffs or technologies as they emerge.

Fuse Energy's app offers a superior, digital-first smart meter monitor experience, transcending the limitations of physical IHDs. It provides real-time data and actionable insights, empowering you to manage your energy consumption effectively and make informed decisions.
