How to identify a Pipit IHD

The Pipit IHD is a black and white device with 'SECURE' written underneath the screen. The display is also black and white.

How can I tell if a Pipit IHD is connected to the HAN?

If you’re experiencing some difficulty with your Pipit IHD, we first need to check whether it is connected to the HAN or not.

Check what the symbol looks like in the top-left corner (next to the time) and compare against this chart:


If your Pipit IHD isn’t connected to the HAN, reach out to our Support team

How to use the Pipit IHD - The Home screen

When the IHD is turned on, it will default to displaying the Home screen. This screen will show differently for single and dual fuel members.

Note - The 'Estimated Bill' is actually the estimated cumulative bill (a running total) since the smart meters were installed, or last tariff change (whichever is more recent). It is not estimating a future bill, it is estimating what you have used up to this point. We advise you to look to previous statements for accurate records of billing rather than this figure, which is estimated and does not include standing charge. 

Dual Fuel


Single Fuel


The Menu

Pressing the 'Menu' button from the Home screen will take you to the Menu.

  • Electricity/Dual/Gas - Press to the return to the Home screen data for either fuel
  • Message - This will show the messages that have been sent by the supplier informing you of tariff updates.
  • History - Shows historical consumption data per hour, day, week, or month.
  • Tariff - Shows tariff details.
  • Account - This is not used by members.
  • Settings - This allows you to personalise the IHD settings.

The Unit Selection button

From the Home screen, if you press A/C, the display will cycle through current consumption figures in kWh, £/h, and CO2 output.

The circular dials show the current energy demand divided into three levels - low, medium and high.

On a single fuel setup, the left side will show the electricity dial and the right will show yesterday's consumption compared to today's.

The Fuel Selection button

From the home screen, pressing the Fuel selection button will change the display from showing dual fuel to electricity or gas only. In this case, the left side of the screen will show the energy demand dial while the right side will show yesterday's consumption compared to today's.

Historical consumption data



When you press the History button you are taken to a screen where you can view historical consumption data for either fuel (press Fuel Selection button), in kWh, £/hour, or CO2 (press Unit Selection button).

The historical data can be shown in four time-frames (press the View button at the top right):

  • Hour - hourly data for the current day - includes a scroll button to navigate forwards and backwards through the graph
  • Day - daily data for the past week, including the current day
  • Week - weekly data for the past month, including the current week
  • Month - monthly data for the past year, including current month

Each history pane will show the highest consumption for the period and the total consumption for the period:

Tariff details

Pressing the Tariff button will show the currently loaded unit rate (standing charge not shown) for electricity or gas. The rates should be shown including VAT.

The Account button

The Account button is used by engineers. If you press it, it will ask you for a vend code (vend codes are normally only used by prepayment customers to top up) to proceed.


The IHD has two LEDs (one for each fuel) which can light green, orange or red.  The colour of the LEDs will show your usage in relation to your energy target. Changing the target can be done in the Settings.

  • Green - under target (low usage)
  • Orange - approaching target (average usage)
  • Red - over target (high usage)




The Settings menu gives access to the following functions:

  • Info - displays connection details of the device, including serial numbers, firmware version, and helpline numbers
  • Target - allows you to set a target for your daily consumption
  • Sound - turn sound on/off
  • LEDs - turns LED indicators on/off
  • Credit Alert - this is an alert used by prepayment customers only
  • DST - turns daylight saving one-hour offset on/off - this should be turned on during summer only
  • Backlight - set the display backlight to turn off after one minute or stay on constantly
  • Network - manually disconnect or reconnect the IHD with the Home Area Network (when pairing/unpairing)
  • Contrast - adjust the screen's contrast level
  • Erase - erase all historical consumption data from the IHD's memory

Setting a target

The current target can be viewed by going to Menu > Settings > Target.  You can view the target in kWh, £/h, or CO2 by pressing the Unit button at the top right of the screen.

To change the target you should press the number button for either electricity or gas and you will be brought to the below screen:


You can use the displayed keypad to set a target. When you press OK you will be taken to a screen summarising the newly updated targets. The new targets will then update the parameters for the green, orange, and red LEDs.

You can see the daily target when viewing the consumption data of individual facts:


...and you can also see it in the Historical Data.


How can I connect the power cable?

There is socket on the back of the unit.  You should insert the power cable into the socket with symbol ‘B’ facing outwards.


How can I turn the IHD on?

When the device is connected to mains power it is always on. After 1 minute of inactivity, the display will go to sleep but will immediately light up again at the touch of a finger. If the unit is being powered by two AAA batteries then it will turn off after 1 minute of inactivity. It can be turned on again by using the battery switch on the left side of the device.


How can I activate the 'boost' function on Pipit IHDs paired to Liberty 110 smart meters?

The boost function is available to those who have a Liberty 110 meter. You can activate this either on the IHD or the meter up to 10 times a day and will turn on anything attached to the 5th terminal for 1 hour, this will be charged at the day unit rate. 

You can activate the 'boost' function on your IHD by pressing Dual Fuel and then clicking on the Status button at the bottom of the screen on the electric side of the display. 



If you have an Aclara or Honeywell/Elster (S2) smart meter, check out this IHD guide. If you have a Secure Liberty smart meter with a Chameleon IHD, see this topic for your IHD guide.

Thanks @richard1966 

Is this the same fault that you posted about here three weeks ago?

Or did that resolve itself and you are now referring to something different?

Userlevel 2

no, it is the same fault it has not been fixed I am fed up of it I think my ihd is not working correctly and it needs sorting or I need a new one

Thanks for clarifying @richard1966 .

Are you aware that in writing to the Forum you are contacting fellow customers? We can help to diagnose problems and offer advice. But we’re not OVO and we can’t “sort out” your on-site meter technology.

I would strongly suggest that you don’t try to get a replacement IHD sent to you. This would not work without first being paired with your Communications Hub. That requires engineers at OVO to agree with you a time-slot within which you will be required to press a sequence of buttons.

It’s pretty unlikely that your IHD is actually faulty. The more probable cause is that there is a communication issue which requires a command to be sent to your site.

Have you made contact directly with Customer Services to report the fault?

Have you checked to see if your IHD is displaying the symbol that shows it has detected the Home Network?

Don’t forget this is a ‘Pipet 500’ IHD. I’ve moved this thread into a guide I made about this IHD type. 







However you can still see the same icon top left that @Transparent has mentioned ^^^

Hi there @BKH !

I’m not quite sure what you mean there I’m afraid. Could you show us some photos of the problem and I’ll see if I can help.


Userlevel 7

Welcome to the OVO online community, @BKH.


Sounds like you’re having some issues using your Pipit In-Home Display. I’ve moved your comment over to our guide to this device, as there’s some great advice in using this IHD here. Check out the guide above and let us know if this helps solve the issue. 


If not we’re on hand to help out here - as @Blastoise186 a photo or more details of what you’re struggling with will really help us get to the bottom of things. :thumbsup:

Good morning @richard1966 . Welcome to the OVO Forum. :)

My name is Blastoise186 and I’m one of the forum volunteers on here. I don’t work for OVO myself so I can’t access your account, but I can help with some advice.

I suspect your S1 meter might potentially be in the process of being upgraded to SMETS1+ right now and under migration to DCC, which can take a few weeks to complete. It will reconnect once that’s all done. As you’ve mentioned health concerns, I have options that can help you out as well.

It sounds as if you definitely qualify for the Priority Services Register, which is a free service that OVO offers to anyone who needs it. Among other things, one of the features is that you can have a meter reader come out and read your meter on your behalf every month if it ever fails to submit readings. This is a completely free service via PSR and the meter reader would ensure that the reading gets sent back to OVO and logged to your account.

If that sounds like something you’re interested in, you can get started very quickly. There’s application forms you can fill out online or by post on that link above (or via the OVO Energy app!), or you can contact the Support Team by phone or live chat and they’ll help you to register. It only takes a few minutes and it will almost certainly benefit you.

I hope this helps, we’ll be here if you have any other questions. :)

Hi there @richard1966 ,

It seems like you’re still having the same issues that you’ve mentioned before. Did you ever manage to get the Support Team to take a look? If you haven’t, then I would definitely recommend it as they might need to investigate what’s going on.

I’ll let @Tim_OVO know that you stopped by as well, just in case.


Userlevel 7

Yep good shout, Blastoise. @richard1966 I’d recommend looking at the topic guide at the top (I moved your comment here) and also this topic , which lets you check the communication of your meters:



It’s worth making sure there’s no communication issues with the gas meter in general. Once confirmed, the Support Team should have all they need to work out what the issue is. Click here and if you choose ‘Online chat’, you’ll probably need to wait less then a minute to get through to someone. 


Keen to hear what the issue was as well!

i have done a smart meter health check on both meters electric is flashing wan light 5 times en pauses also han showing on meter and date time and month correct. on gas meter han solid on gas meter and date and time correct. why does it take 45 days to rectify this problem  i wish now i had never had smart meters installed as i have still got to read gas.


Userlevel 7

45 days is roughly six weeks, which is needed to allow enough time to investigate deeper issues that can’t be resolved quickly - usually because of things like the issue being a technical one, or where a third party is involved for example. The exact list can vary, but it’s quite common for anything that gets escalated to take longer to resolve than things which can be resolved immediately over the phone or live chat. This is true with just about anywhere to be honest.

It sounds like someone is looking into your issue at the moment, but you didn’t mention whether the GAS light on your meter is flashing or not. Please could you show us some photos of your meters - especially with the display on the gas meter lit up and clearly visible. I can’t speed up the fixes, but it can help me to gather some clues.

Userlevel 2

my gas meter is a smet one type it does not have a flashing light just  HAN in solid letters which means it is connected to the network

Thanks @richard1966 - it’s really handy to have this info so we know what’s been ruled out!


Are you aware of your SMETS1 smart meter being upgraded to become ‘SMETS1+’, as blastoise mentioned earlier in this thread?


We are aware of some display devices (such as your Pipit) having some issues following this upgrade, in recent weeks. This might be related… My advice isn’t of much help for you in this case, but as you’ve mentioned a time frame for Support, it sounds like you’ve already raised this. So that’s a great step and means you don’t need to do any more leg work. It’s been enough already!
