A quick breakdown on how to use a smart meter app

What is a smart meter app?

A smart meter app is a digital dashboard that connects to your smart meter and shows your energy usage in real time. It allows you to see how much electricity and gas you’re using and how much it costs.

How smart meters and apps work together

Your smart meter should automatically send readings to your supplier. The app then displays this data in a clear and accessible way, often broken down by hour, day, or month. This means you should no longer need to rely on manual meter readings or estimated bills as long as your meter is connected.

Key benefits of a smart meter app

Using a smart meter app gives you better visibility over your energy use. Instead of waiting for a bill, you can see your usage as it happens and understand how different appliances affect your consumption. It also makes it easier to track spending, spot unusual usage, and manage your budget more effectively.

How smart meter apps help you save money

One of the biggest advantages of a smart meter app is cost control. By seeing your usage in near real time, you can identify when you are using the most energy and adjust your habits. For example, shifting usage to off-peak times can reduce costs, especially if you are on a time-of-use or EV tariff. Shifting usage to off-peak times helps balance the grid and is the basis for earning Energy Dollars as part of The Energy Network. Click here to find out more about The Energy Network.

Using smart tariffs with your app

Smart meter apps work closely with modern tariffs that rely on real-time data. EV tariffs and time-of-use tariffs use this data to offer cheaper rates at certain times of day. To access these tariffs, you typically need a connected smart meter that can provide detailed usage data.

What happens when you switch supplier?

Smart meter apps are linked to your supplier, so when you switch, you will usually move to a new app. However, your smart meter should continue to work, especially if you have a SMETS2 meter. Older SMETS1 meters may require upgrades or reconnection to maintain full functionality.
