Using your Secure SMETS1 In-Home Display (IHD)

If your previous supplier installed a SMETS1 meter at your property, and it was manufactured by Secure, they should have given you an In-Home Display (IHD). This is a small electronic screen with the manufacturer’s name ‘Secure’ written on it. 

If you weren’t given a Secure IHD by your previous supplier, we’re unable to supply one.

Once your IHD is set up, you can start using it to keep track of how much energy you're using with Bulb.

Connecting your In-Home Display (IHD) to your smart meters

To get your IHD working, you’ll need to plug it into a power socket and charge it up. When it’s finished charging, turn it back on. The on/off button can be found on the side of your IHD. 

Your IHD should automatically reconnect to your smart meters. This can take up to 10 minutes. 

And while it’s doing that, you’ll see a flashing diamond-shaped icon with an exclamation mark inside, in the top left of the screen. Once it’s connected to your smart meters, this will be replaced by the network connection symbol - 4 curved bars ordered by size (labelled '1' in the example below). 

What the symbols on your Secure IHD home screen mean

Once your IHD is connected to your smart meters, you’ll see the home screen. This shows your ‘Usage Now’ - and it says this in the middle of the screen, at the top.

The usage data you see on the home screen is updated approximately every 10 seconds for electricity and every 15 minutes for gas.

An In-Home Display screen showing electricity usage on the left, gas usage on the right, the date, the time, and a menu button.

  1. Network strength - these 4 curved bars show the strength of the signal between your IHD and your smart meters. The more bars you see, the stronger the signal. If you can see:

    • 4 bars - your signal strength is good
    • 2 bars - your signal strength is poor, try moving the IHD closer to your electricity smart meter
    • a diagonal line through the bars - your IHD isn’t communicating with your smart meters
    • an exclamation mark (!) - there’s currently no network connection. If the exclamation mark is flashing rapidly, this means your IHD is still trying to connect, so you might need to wait a little longer

  2. The time - you can use your IHD as a digital clock.
  3. Usage Now - this is the name of the home screen, which is the first screen you’ll see when you switch on your IHD.
  4. Fuel button - use this button to view your usage for different fuel types. Press this to cycle between: 

    • Elec - electricity only
    • Gas - gas only
    • Dual Fuel - both gas and electricity

  5. The date - your IHD will show you what day it is.
  6. Demand indicator - this shows how much energy you’re consuming. Electricity is updated every 10 seconds, and gas every 15 minutes.
  7. Meter mode - the letter in the bottom left or bottom right of the screen tells you which type of meter you have. Or, if you’ve got a prepay (top up) meter, the type of credit you’re using:

    • P = Prepayment
    • C = Credit 
    • E = Emergency Credit 
    • F = Friendly Credit 

  8. Usage or cost - this shows your usage now in pounds and pence (£), or kilowatts (kW), and you’ll see the number change as your usage changes.
  9. Unit button - press this button to cycle between the following units for measuring your energy consumption:

    • £/h - cost per hour 
    • kWh - kilowatts per hour
    • CO2KG - the amount of carbon emissions created per unit of fuel used

  10. Usage rate - this tells you how much energy you’re using, according to your pounds (£) per day target: 

    • ECO - this means your energy usage is low, and you’re within your £ per day target
    • MED - this means your energy usage is about average, and you’re within your £ per day target
    • HIGH - this means you’re using a lot of energy, and you’re likely to exceed your £ per day target if you continue using energy at this rate

    To set a daily target, press: Menu > Settings > Target menu

  11. Fuel icon - the lightning bolt symbol to the left indicates electricity, and the flame symbol to the right indicates gas.
  12. Menu button - press this to bring up the different menu options for your IHD, including how to view your previous usage and check your tariff details.

If there's an envelope in the top right of the screen, below the date, it means there’s an unopened message waiting for you. Press the envelope to read it.


What the buttons on the main menu do

Press the menu button at the top left of the screen to access the different options on your IHD.

A menu of options, with buttons along the top for 'Electricity' 'Dual' and 'Gas', and 'Message', 'History', 'Tariff', 'Payment', and 'Settings' buttons along the bottom.

On the ‘Menu’ screen, you’ll see individual fuel buttons along the top row for Electricity, Dual (that’s gas and electricity), and Gas. Press any of these buttons to view the consumption of your chosen fuel.

Across the bottom, left to right:

This is where messages and notifications about your tariff are stored. Occasionally, we might send you a message on your IHD. And if we do that, we’ll always email too.

Press this to view your usage over the past hours, days, weeks or months. 

Press this to get a breakdown of your tariff costs for each fuel. If Bulb supplies both your gas and electricity, press the Fuel button to switch between fuels. 

If you’ve got a prepay (top up) meter, you can use your IHD to view your last 5 meter payments. Go to: Menu > Payment > History. This is also where you can manually top up your meter, or add emergency credit to your meter, if you need to.

Press the Settings button to:

  • find Bulb’s member helpline details
  • reset your IHD
  • set a consumption target - pounds (£) per day
  • set up a low credit alert - this feature is only available if you’ve got a prepay (top up) meter
  • adjust the basic settings of your IHD - like the brightness and contrast of your screen

Viewing your previous usage

To view your previous usage, from the home screen, press Menu and then press the History button.

If you’ve just switched your Secure IHD back on and there aren’t any charts here yet, check back again in 1 to 2 days.

A chart will appear on your screen showing your usage. It might look something like this:

A screen with a graph on it showing electricity usage over the last 12 hours, with buttons to switch between periods of time, kilowatt hours, and cost.
This screen shows an example of a member viewing their electricity usage over the last 12 hours in kilowatt hours (kWh).

In the top right corner of the screen is a button that will say either Hour, Day, Week, or Month. Press this button to cycle between the options. 

Next to this is the unit button. Press this to view your previous usage in kilowatt hours (kWh), pounds and pence (£/h), or by the amount of carbon emissions produced per unit of fuel (CO2KG). 

The fuel button is in the centre of the screen. It will either say Electricity or Gas. Press this button to switch between fuels.

There are arrow buttons to the left and right of the chart. Press on the arrows to move backwards and forwards through the data for your chosen time period.

To go back to the main menu, press Menu in the top left of the screen. 

Topping up your Secure SMETS1 meter using your IHD

This option is only available for members with a prepay (top up) meter.

To top up your meter using your IHD, you’ll need a UTRN (sometimes called a ‘vend’ code). This is either a 20, 40 or 60 digit code that will either be:

  • on your receipt - if you bought your top up at a PayPoint, PayZone or Post Office
  • sent to you via email - if Bulb can’t communicate with your meter, or your top up hasn’t worked, we’ll email you your code

To top up your meter from the home screen, press Menu and then press the Payment button. This will take you to the ‘Transaction’ screen - you’ll see the name in the middle of the screen, at the top. 

If you pay for both of your fuels by top up, you’ll be asked to choose which fuel you’d like to top up.

A screen with a numerical keypad to the right, an 'Enter' button, a 'Delete' button, and to the left is a 'History' button.

Enter your UTRN code into the rectangular box at the top of the screen, above the keypad. When you’re done, press enter to add the top up to your meter.

It can sometimes take longer to top up your gas meter than your electricity meter. Once your payment has gone through, your IHD will display a ‘Payment successful’ message. 

If your top up fails, your IHD will display a ‘Payment unsuccessful’ message with some more detail about what went wrong. If this happens, you’ll see a Try again button. Press it to re-enter the UTRN.

You can check your top up history at any time by pressing History in the bottom left of the ‘Transaction’ screen. This will show your last 5 transactions.


Activating emergency credit using your Secure IHD

If the credit on your meter runs out, or it drops below your low credit level, you’ll see a ‘Zero Credit’ or ‘Low Credit’ warning screen.

To get an alert when your top up is about to run out, you can set up a low credit level warning. From the main menu, press Settings then Credit alert.

On the warning screen, press E-Credit to activate emergency credit. 

Two screens, the first says 'Low credit' 25p, the second screen says 'Credit = £0.00 supply off'.

You can also choose to Top-up or press OK to dismiss the warning and go back to the home screen. 

If you press OK when the ‘Zero Credit’ warning screen appears, your home screen will display a message to let you know your supply has been turned off:

A screen that says 'Supply off' to the left, and two bar charts to the right comparing today's and yesteday's electricity usage.

To activate emergency credit from this screen, press E-Cr in the bottom left. When your supply is back on, the message on your screen will change to say ‘Emergency Credit ON’.

You can also add emergency credit directly on your meter. Find out more about activating emergency credit on your meter.

To avoid your supply going off suddenly, we recommend topping up your meter regularly or setting up a low credit level.
