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. 


Not got a smart meter yet? Book in your S2 meter fitting appointment, here. You'll need your account number to book this in, which you can find in your online account, here.

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 1

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 ^^^
