SMETS2 In Home Displays (IHD): which type do I have and how can I spot and fix issues? DIY tutorial series
Userlevel 7

Updated on 23/10/20: If you have a ‘Secure Liberty’ SMETS1 smart meter with a Chameleon IHD, see this topic for your IHD guide. If you have a ‘Secure Liberty’ SMETS1 meter with a Pipet IHD, see this topic for your IHD guide.

How to identify the IHD models


It’s important to understand what type of IHD you have before trying to troubleshoot any issues.

We have used three different types of S2 IHDs so far. Currently we are sending the new Chameleon IHD6 (referred to as simply IHD6) to customers with S2 meters. You can find a description of these scrolling down.

These are the different types:

IHD6-CAD-PPMID - also known as the IHD6


This device looks similar to a Pipit, as it's got a black front, white back and a touch screen. If in doubt, check the device has the word "Secure" written at the bottom of the screen - if it doesn't, then it is an IHD6 and perfectly compatible with S2 meters.

Unfortunately there is no user guide available for IHD6s at present.


 

IHD6-CAD-PPMID


IHD3-PPMID TYPE2 - also known as IHD2


This has the same appearance as the old S1 Chameleons (IHD3-CAD), except the S2 IHDs have an on/off button on the back of the device, and will have 'IHD3-PPMID TYPE 2' written on the bottom.
 

IHD3-PPMID TYPE2

IHD3-CAD-PPMID TYPE1 - also known as IHD3.


They have the same appearance as the standard IHD2 but will have 'IHD3-CAD-PPMID' written on the bottom.  

Benefits of connecting your IHD to Wi-Fi


The IHD does not connect to your online account. However, connecting to WiFi on IHD6 allows us to make any firmware updates to the IHD remotely. It also allows you to see when an IHD stops working and better troubleshoot any issues, as it provides information the IHD is displaying.

Engineers are advised to pair the WiFi up on every job they do, however sometimes this is not possible and it is not mandatory.

Is the IHD showing too high consumption?


This is a known issue with the firmware on some electric meters installed towards the beginning of the S2 roll out. This has been shown to cause members' IHDs to show high usage. Firmware updates are being performed on a number of S2 meters.

If you’re seeing high usage, reach out to our
Support team 


 
What to do if you’re having an issue with your IHD


First, check whether there is an issue with the HAN (rather than the IHD itself). You can do this by checking how regularly the HAN light is flashing on the comms hub. See this SMETS2 smart meter guide if you’re not sure how to do this.

 

Another indication would be that there is no consumption data for electricity meter, gas or both showing on the device. If there is a possible HAN/WAN issue then complete a smart meter health check.

If the IHD is showing missing data for one or both fuels and the meter comms are fine, you should perform the following checks.


1 - Check the distance to the electricity meter, has the IHD been moved? 

 

Try to keep the IHD within a max of 7 yards from the electricity meter. The signal will decline significantly with walls.

2 -  Has the IHD shown data previously or has anything changed e.g. obstructions?

 

If the IHD was previously showing data, check if anything has changed in the home that could have caused the loss of communication.

3 - Is the IHD showing the correct time?

 

If it's not showing the correct time, the IHD is not paired.

4a - IHD2 and IHD3: Check wifi symbol - is it flashing/solid?

  • No wifi symbol & incorrect time > Needs to be paired by our Support team 
  • Wifi symbol flashing > Our Support team may be able to sort by unpairing and pairing the device
  • Wifi symbol solid > No issue with Wifi pairing

4b - IHD6: Check the signal bars

Signal bars solid > IHD is paired.
Signal bars flashing > Needs to be paired by our 
Support team 

5 - Try turning off for several minutes before turning back on.


What happens if I’ve broken or lost my IHD?


Please reach out to our Support team to discuss this. We may be able to offer a replacement. 

IHD is showing text in Welsh


Occasionally, IHDs have been known to default to Welsh. Follow these steps to change back to English:

1. Tap the”OK” button at the bottom of the IHD screen.
2. Tap the right arrow until you see “Gosodiadau Wedi anfon yr” and tap OK.
3. Tap the right arrow 8 times until you reach the option “Dewis iaith Wedi anfon yr” (if this doesn't work, you may need to try the next option: “Clirio Gosodidau Wedi anfon yr") and tap “OK”.
4. Tap the left arrow to select English, then tap "OK".
 
 

A useful tip...

You can tell whether a device is an IHD2 or IHD3

  • On the box the IHD was packaged in
  • On the IHD, next to the device ID

  • Unfortunately there is no user guide available for IHD6s at present.



Pairing and unpairing the SMETS2 Chameleon IHD3 and IHD6s
 

Our Support team will need to work with you to get this device ‘unpaired’ from your HAN. 

 

How to unpair the old IHD3 CAD


Reach out to our 
Support team, and they will perform some actions on our systems. Then you will need to do the following actions on the device:

  1. Tap ‘OK’
  2. Scroll right to ‘Adjust Settings’ and tap ‘OK’
  3. Scroll right to ‘Set Budget’ and tap ‘OK’
  4. Turn off the device and turn it back on again
  5. Tap ‘OK’
  6. Scroll right to ‘Adjust Settings’ and tap ‘OK’
  7. Scroll right to ‘engineering’
  8. ‘Leave network’ (Tap ‘OK’)
  9. Wait for 10 seconds - IHD will display message that it is leaving the network
  10. After 5 seconds, IHD will leave the network and factory settings will be restored


How to unpair the old IHD6

 

Reach out to our Support team, and they will perform some actions on our systems. Then you will need to do the following actions on the device:

  1. Go to set budget screen (menu>budget) and power off PPMID from this screen (hold power button on the back for 5-10 seconds).
  2. Turn PPMID back on by pressing the power button on the back.

The device should now be decommissioned. This will be shown by no meter information or usage information being displayed.

How to pair the IHD2/3 CAD

 

Reach out to our Support team, and they will perform some actions on our systems. Then you will need to do the following actions on the device:

  1. Power Up their device
  2. Once it’s on the home page Press OK
  3. Scroll to settings
  4. Press OK
  5. Scroll to engineering settings
  6. Press OK
  7. Join network
  8. Press OK

The IHD should then pair over the next few minutes. You can check this by the wifi symbol in the left corner appearing and turning solid and consumption data will be shown.

How to pair the new IHD6-CAD-PPMID


When you get your new IHD, we will need to pair it for you, as this is done by opening the HAN network. Before this happens, the meter will look like this:
 


Reach out to our Support team, and they will perform some actions on our systems. Then you will need to do the following actions on the device:

  1. Press Menu (the icon with 6 white boxes in the bottom right corner)
  2. Press the right arrow to get to the second screen of menu options
  3. Press Settings
  4. Press the right arrow to get to the second screen of settings options
  5. Press Config Menu
  6. Press Join Network
  7. Press Yes

After a short period, the PPMID will make an audible beep. The PPMID device should now display the correct time in the top centre of the screen.


 
Lastly, setting up WiFi on the IHD6


What is the benefit of connecting to WiFi on the IHD?


Connecting to WiFi on IHD6 allows us to make any firmware updates to the IHD remotely, and also allows you to see when an IHD stops working and better troubleshoot any issues. It also gives us the information the IHD is displaying so that we can diagnose any issues that may occur.

To pair to the Wifi, follow these steps:

1. Tap the menu button in the bottom right corner of the screen.

 


2. From the menu screen, tap the right arrow to go to the next page. 

 


3. Tap ‘Settings’.

 


4. Tap the 'Wi-Fi' icon. 

 


5. Tap the button to turn the WiFi on.

 


6. Once the WiFi is on, tap 'Scan' to show the available networks or press WPS Push if the router you’re trying to join supports this function.

 


6A) If choosing WPS Push - press the WPS button on the router when this symbol is displayed. 

 


6B). If choosing Scan - Once you’ve selected the network you wish to join, enter the password and press ‘Join’.

 


7. The device will now connect to the WiFi.

 


8. If the password is correct, the device will show a Connected status.
