In-Home display: your smart meter companion

An In-Home Display (IHD) is a portable screen that gives you immediate insights into your household's energy consumption. This small device connects wirelessly to your smart meter, translating complex energy data into an easy-to-understand format. It shows you exactly how much electricity and gas you are using and what it is costing you, acting as a direct window into your energy habits. This empowers you to make informed decisions about how you use power in your home.

Understanding your energy usage is key to managing your bills. With a smart meter and an IHD, you gain valuable insights, and the Fuse Energy app can act as a remote IHD, showing your hourly, daily, monthly, and annual usage.

What is an In-Home Display (IHD)?

An IHD is essentially your smart meter's companion, designed to bring your energy data out of the meter cupboard and into your living space. It is a crucial tool for anyone looking to understand and manage their household energy use more effectively.

The purpose of an IHD

The primary purpose of an IHD is to provide immediate feedback on your energy consumption. Instead of waiting for a monthly bill, you can see your usage in near real-time, allowing you to observe the impact of turning appliances on or off. This transparency helps demystify energy bills and puts you in control of your consumption.

Key information your IHD shows

Your IHD typically displays several key pieces of information. It shows your current electricity and gas consumption in kilowatt-hours (kWh), along with an estimated cost in pounds and pence based on your current energy tariff. Many IHDs also offer historical data, allowing you to review your usage daily, weekly, or monthly, helping you spot trends and identify periods of high consumption. Some models may even use a traffic light system (green, amber, red) to indicate your current usage level.

How your IHD works with your smart meter

Your IHD and smart meter work in tandem to provide you with up-to-the-minute energy data. The connection between them is designed to be secure and efficient, ensuring reliable information flow.

The connection between your IHD and smart meter

In-Home Displays communicate with smart meters using a secure wireless protocol. This technology creates a local network within your home, known as a Home Area Network (HAN), allowing the IHD to receive data directly from your electricity and gas smart meters without needing your home Wi-Fi. This dedicated connection ensures that your energy data is transmitted reliably and securely.

Data flow: from meter to display

The smart meter, installed where your old meter used to be, measures your energy consumption and then transmits this data wirelessly to your IHD. For electricity, this data is often near real-time, while gas usage typically provides one daily cumulative reading. Your IHD then processes this raw data, converting it into easy-to-understand figures like kWh consumed and estimated cost, which are then shown on its screen.

The power play: benefits of using your IHD

Using your IHD is more than just monitoring; it is a power play in managing your household energy. It gives you the advantage of real-time insights to make smarter decisions about when and how you use energy, shifting control into your hands.

Real-time energy insights for informed decisions

The immediate feedback from your IHD allows you to see the direct impact of your actions. Turn on a high-power appliance, and you will see your consumption figures rise instantly. This direct correlation helps you understand which appliances are energy-intensive and when you might be using more energy than necessary. This awareness is the first step towards making informed choices that align with your energy goals.

Understanding costs and consumption patterns

Your IHD helps you track your energy spending against your budget and identify patterns in your consumption. By reviewing daily, weekly, or monthly usage, you can pinpoint peak consumption times. For instance, you might discover that your energy use consistently spikes during certain hours, prompting you to investigate why and consider adjustments. This detailed view helps you understand not just how much you are using, but when and how you are using it.

Optimising energy use for efficiency

With a clear view of your energy habits, you can start to optimise your usage. If you are on a time-of-use tariff, your IHD shows usage and estimated cost, allowing you to infer the financial benefit of running appliances like washing machines or dishwashers during off-peak hours when electricity is cheaper. Even on a standard tariff, identifying and reducing 'phantom loads' (energy consumed by devices on standby) can lead to noticeable savings. The average UK home uses around 2,500 kWh of electricity and 9,500 kWh of gas per year, according to Ofgem's typical domestic consumption values (TDCV)1. These figures provide a benchmark for your own household's efficiency efforts.

Getting and maintaining your In-Home display

IHDs are a standard part of the smart meter rollout, ensuring most households with smart meters have access to this valuable tool.

How IHDs are supplied

Energy suppliers are generally responsible for providing In-Home Displays as part of the smart meter rollout. They are typically provided free of charge when your smart meter is installed. If you have a smart meter but no IHD, or if yours is faulty, you should contact your energy supplier. They can advise on options, which may include a replacement, though eligibility and availability can depend on factors like the age of the IHD and the cause of the fault.

Caring for your display

IHDs are designed to be user-friendly and require minimal maintenance. Keep your IHD plugged in or charged to ensure continuous data display. Placing it in a central location, not too far from your electricity meter, can help maintain a strong connection. If you move house, remember to leave the IHD behind, as it is paired specifically with the smart meter at that property and will not work elsewhere.

Troubleshooting common IHD problems

Like any electronic device, your IHD might occasionally encounter issues. Many common problems can be resolved with simple troubleshooting steps.

My IHD is blank or not displaying data

If your IHD screen is blank, first check if it is plugged in and switched on, or if its batteries need replacing. If it is powered but still blank, try restarting it by unplugging it for a few minutes and then plugging it back in. Sometimes, a simple reboot can resolve display issues.

Reconnecting your IHD to your smart meter

If your IHD is powered but not showing data, it might have lost its connection to your smart meter. Try moving the IHD closer to your electricity meter. Many IHDs have a 'reconnect' option in their menu; consult your IHD's manual for specific instructions on how to re-establish the connection. This process often involves pressing a button on the IHD to re-pair the devices.

When to contact your energy supplier

If basic troubleshooting does not resolve the issue, or if your IHD is physically damaged, it is time to contact your energy supplier. They can offer further support, diagnose more complex problems, or arrange for a replacement if necessary. For Fuse Energy customers, our 24/7 human customer support is always available to help with any IHD queries or troubleshooting, ensuring you have reliable assistance whenever you need it.

Making the most of your IHD data

Your IHD is a powerful tool; understanding how to interpret its data can unlock significant opportunities for smarter energy management.

Interpreting trends and identifying energy hogs

Look beyond the daily numbers. Observe your energy usage over weeks and months to identify recurring trends. Do you consistently use more energy on certain days or at specific times? This can reveal habits or appliance usage patterns you might not be aware of. High spikes in consumption when a particular appliance is running can help you identify 'energy hogs' - devices that consume a lot of power.

Actionable steps for smarter energy management

Once you understand your usage patterns, you can take actionable steps. For example, if your IHD shows high electricity use during the evening, consider if you can shift some activities, like charging devices, to off-peak hours if you have a time-of-use tariff. Regularly checking your IHD can also prompt you to turn off lights or appliances when not in use, reducing unnecessary consumption. Using your IHD effectively is a continuous process of observation, adjustment, and optimisation, giving you the power to play with your energy usage and make it work for you.
