Use the touch buttons to control your in-home display and find out how and when you're using energy in your home: ​

HOME - go to the home screen

This shows today's energy use so far. If you're on a prepayment tariff, you will see the remaining available credit balance. (see "smart-pay" for more).

NOW - see the electricity you are using right now

FUEL - Select gas or electricity and see your energy use by fuel type or the combined total.

Energy Usage Dial

The energy usage dial lets you see instantly if your electricity usage is low, medium or high. You can view this as electricity used: right now, so far today, this week, this month or this year.

Low is green

Medium is amber

High is red

Electricity Now Lights

The coloured lights at the bottom of the display show your electricity use right now as either low, medium and high. So if the kids have switched all the lights on and the tumble dryer's spinning round, you'll be able to tell at a glance. 

Tailored over time

Your in-home display will initially compare your energy usage against a medium sized household. However, it will "learn" your typical usage over time and adjust to reflect low, medium and high use for your individual household.

Setting your budget 

You can set a budget to help you stay on track with how much you spend on energy. 

  • Press <Menu / OK>

  • Go to <Settings>

  • Select <Set Budget> 

  • Press <Menu / OK>

  • Use the arrows to set your budget

  • Change your fuel type and preferred time period (day, week, month) and view your budget in £s.

You can now easily keep track of your budget by checking the energy usage dial on your home screen. You will hear an alarm when you exceed your budget. You can turn this on or off in the Settings menu.

You can experiment with the time period of your budget. If you set a monthly budget, see what that means to your daily cost and what your annual savings could be.

Getting the most out of your device

Your in-home display can help you understand how, when and where you use energy in your home. You can make informed choices about how to be more energy-efficient and save money.

As your in-home display has a built-in rechargeable battery and connects wirelessly to your smart meter, you can walk around your home and investigate what your appliances cost to run and where you can make savings. Generally, you'll find that things containing a heating element can be more expensive to run: tumble dryers and fan heaters for example. But don't just take our word for it, you've now got all the tools you need to check it out yourself.

Press the NOW button to see your instant electricity use. Turn each appliance on and off and see how much your costs change. You can determine approximately how much electricity each appliance uses.

We have a really helpful video with energy-saving tips here. Well worth 2 minutes of your time.
