Geo Trio 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. Your in-home display is set to an “average” household, but after a couple of weeks it will learn the average for your home. Your bill shows vat and standing charges separately, while the in-home includes these in the energy costs displayed.

A Home Use this touch control to cancel what you’re doing and go to the home screen. B Now Shows what you’re using right now. C Fuel If you’re tracking electricity and gas, the home screen shows you both combined. If you want to see this individually, tap on the fuel button. One tap for electricity, two for gas, three to show you both together. D Calendar Use this to check what you used today – or so far this week, month or year. Tap once for a view of this week, twice for this month – and three times for this year. If you want to see what you’ve used in previous weeks or months, use the arrow keys as well. E Menu/OK Tap OK, then use arrows to scroll through your account information, meter readings, settings and to set your budget. F Forward and back. Use the arrows to scroll through options or information on the screen. On the home screen, you can use the arrows to move between days to see your usage over the last week.

Gas meters

To take the reading from your gas meter, you’ll need to press a button to wake up the meter. Depending on your meter, it’ll be either an OK button, a red “A” button or a round button between two arrowed buttons. The reading will appear on the screen. As your gas meter is powered by a battery, the screen will go blank after a short while to save power.

Electricity meters

On most electricity smart meters, the screen will show your meter reading as standard. If you see a row of zeros, wait six to ten seconds for the screen to show your meter reading. On some meters, you may need to press the OK button or button A to show your reading.


Standard smart meter

Have a look at the display panel on your Smart meter, normally it’ll be blank. Press button ‘A’ or ‘B’ to wake the screen up. Press button ‘A’ again to show the meter reading and make a note of the numbers including any zeros. There’s no need to note down any number(s) after the decimal point.
If you have a single rate meter: Always read the ‘R1’ register and simply write down the numbers from left to right.

Economy 7 smart meter

If you have a two-rate meter: You’ll only need to read the ‘R1’ and ‘R2’ registers. Press button ‘A’ to cycle through the readings and write down each one as it appears.
If it’s peak time when you read the meter, the active register shows your Day/Normal rate reading. If it’s off peak the meter will show your Night/Low rate reading. You’ll notice that one of the registers has “Now” in the top right hand corner of the display. This shows your active register.

  1. If you have a Feed-In Tariff, these symbols show whether you’re currently importing or exporting electricity.
  2. This tells you whether your energy is ON, OFF or READY. The plug symbol refers to your electricity, and the flame is gas. In this illustration, the plug is black while the flame is grey, so the information refers to electricity. If your screen shows OFF or READY, your meter is off supply – so you need to wake it up and get it back on supply. To do that, simply press any button.
  3. If you’ve got unread messages from us on your smart meter, this symbol will be lit.
  4. This tells you which unit of energy you’re looking at. M³ (cubic metres) is gas and kWH (kilowatt hours) is electricity.
  5. HAN stands for Home Area Network. This is the network that smart meters use to communicate with each other, and with your IHD. The symbol on the screen shows that the meter has been set up to provide a HAN, although it may not be communicating with other devices if it hasn’t yet been linked to them.
  6. These shapes become letters or numbers on active meters. They either show messages or amounts, such as how much energy you’ve used, or how much credit you’ve got.
  7. To take a reading, press ‘9’ on your smart meter keypad. This will show the meter reading in kilowatt hours (kWh) for electricity, and cubic meters for gas.
  8. If your smart electricity meter is on an Economy 7 tariff (where you pay a standard price during the day and a lower rate for 7 hours overnight), press ‘6’, then press three more times until you can see ‘IMP R01’. This shows your off-peak (night-time) reading in kWh. Press ‘6’ again and you’ll see ‘IMP R02’. This gives your daytime reading.
  9. We’re asking anyone who doesn’t have a smart meter to submit their readings through their online account or in the OVO app. This is because we’re now only able to take emergency calls, so we can help those who need us most. It’s really easy to submit readings this way – and we thank you for your support.


Standard electricity tariff

  1. Press 9 on the keypad.
  2. You’ll see the letters “IMP R01” appear on the screen.
  3. Wait a moment – then eight digits will appear, followed by “kWh” towards the bottom right of the screen.
  4. Take the first 7 digits – this is your reading.
  5. To take a meter reading on an Economy 7 electricity tariff:
  6. Press 6 on the keypad four times.
  7. Wait a moment – your day/peak and night/ off-peak readings will show up on the screen one after the other, starting with off-peak.

  9. For your peak reading you’ll see “IMP R02”. A second later, you’ll see eight digits, with “kWh” towards the bottom right of the screen. You’ll only need to take the first 7 digits when taking each of these readings (i.e. nothing after the decimal place).
