The Tempo App allows you to see, explore and analyse how much electricity and gas your home uses (along with how much it costs) from wherever you are in the World. Think of Tempo as your virtual in-home display.

Tempo not only allows you to monitor your electricity and gas usage, but it can also keep you updated on unusual energy usage with the aim of keeping you within your energy budget.

Please note: You need to have a smart meter and a Trio II in-home display (with Wi-Fi) already installed in your home for the app to work.

Keep track of current energy use


Use the Tempo App to keep track of how much electricity and gas you are using in real-time, the app will even break the cost down per hour so you know exactly how much it is costing.

Explore past energy use


Take a look at your historic energy data (view the past day, week, month or even year) to spot trends and keep tabs on your energy use over time.

Set (and stick to) your budgets


The Tempo App lets you take control of your energy bills by giving you the ability to set budgets.

The app provides an overview of your electricity and gas usage and costs in real-time to help you make adjustments to stay within budget.

Detailed balance and meter info


Not only can you view your tariff and balance within the app, you are also able to see your current meter balance at a glance!

Temperature tracking


You can use the Tempo App to view the current temperature in your home (taken at the location of your in-home display). If it is getting toasty, it might be time to turn down the heating (and save on associated gas costs).
