my energy live is a free Android app developed by British Gas Trading Ltd. that lets you monitor your energy usage from anywhere. However, before downloading the app, you need to make sure that you have a smart meter installed by British Gas and a British Gas smart energy monitor connected to your wifi router to function correctly.

Once you have the necessary equipment, you can connect to your British Gas smart energy monitor and check your energy usage at any time. The app allows you to see how much energy you have used so far today, if you're using more than usual, how much electricity has been used in the last hour, how much electricity is currently being used, and your current balance if you're a Pay As You Go customer. This information can help you keep track of your energy spending, and make choices to save on your energy bills or use your energy more efficiently.

To use the app, you'll need to sign in with your British Gas online account or register to create one. Overall, my energy live is a useful app for British Gas customers with a smart meter and smart energy monitor who want to monitor their energy usage and keep track of their spending.
