Make the most of your smart meter in-home display

Your in-home display works by talking to your meter and giving you constant updates on what you’re using. Your electricity info updates about every 30 seconds and your gas about every 30 minutes. When you switch your in-home display on, it takes a moment to “find” the meter and start talking to it. It should take less than a minute for your electricity consumption to display – and a couple of minutes for your gas information to show up.
Your in-home display is set to an “average” household, but after a couple of weeks it will learn the average for your home.

Before you start

There are a few practical things you need to be aware of before you use your display. They’ll help you get fully up and running safely.

Charging your display
It’s best to leave your smart meter display plugged into the mains. It has a built-in rechargeable battery which should last for around four hours if it isn’t plugged in. If the battery does get low, the low battery icon will flash and it takes about three hours to charge.

Find a suitable location
It’s a good idea to keep the in-home display somewhere where you can always see it. This will help you keep an eye on the traffic light system and make you more aware of how and when you're using your energy. Try to keep the display near your actual smart meter to make sure the two are connected. 

Smart meter connection
If the message ‘connecting to smart meter’ is displayed more than one hour after turning it on, move it closer to the electricity/gas meter. If problems continue, call the smart metering team on 0333 009 7000(1).

What's on your in-home display monitor?

  1. Signal strength - Shows if your in-home display is close enough to your meter.
  2. Battery - Remember to plug your in-home display in and keep it charged. There are two battery symbols. One shows ‘low battery’, the other shows whether ‘mains connected’. They should not appear at the same time.
  3. Budget marker - Shows the maximum you want to spend each day.
  4. Cost display - Shows your costs. Use the arrow keys in the control panel to scroll back through costs for previous days. Consumption (kWh) is shown on the lower display. This will swap over when looking at how much energy you’re using.
  5. Budget dial - See how much of your daily budget you’ve used.
  6. Fuel view - See your electricity use, gas use – or both.
  7. Control panel - Use this to control your in-home display.
  8. Traffic light - Shows you how much energy you’re using right now. Green is great. Amber means you’ve got a few things on. Red means it’s time to switch something off! Remember, your in-home display takes a few days to learn what’s normal for you – so keep an eye on what the traffic light is telling you over the weeks to come.
