Chameleon IHD Health Check - Your Guide
Noticed an issue with your Chameleon In-Home Display, this guide is here to help. We know how useful these devices can be for keeping an eye on the usage data we’re receiving from your smart meters so want to make sure any technical bugs can be ironed out! 
Missing some data, spotted some incorrect unit rates (excluding the 5% VAT difference) or has the device started rebooting? These could all indicate an issue we may be having with the connection between us and your meters (also known as the Wide-Area Network or WAN) or between the device itself and the smart meters (also known as the Home-Area Network or HAN).
Newly installed Smart meters?
Eager to get tracking your smart meter usage data straight away? We hear ya! Whilst most devices are up and running from the date your new meters are installed, it’s not unusual for them to lose some data or experience a few teething-issues as we carry out some behind-the-scenes initialising process (read more about these on this great user-guide). We’d recommend keeping the device plugged in close to your electricity meter if you notice any issues during the first 6 weeks following a smart meter installation - hopefully things should start working as expected once the smart meters are fully up and running but if not, read on to check our next trouble-shooting steps.
Checking the smart meter connection (WAN) via your Online account or OVO App
Been over 6 weeks since the smart meters we’re installed and you’re still noticing issues with your Chameleon device ? - It’s time to start doing some investigating! First place to check is your online account or OVO app (download for Android or iOS). If we’ve lost connection to your smart meters, you should see a message on screen to let you know.
In this case the best next steps would be to carry out a smart meter health check for your meter type below and forward the results on to our Support Team:
Once any communication issues with your meters are resolved, we’ll be able to get your IHD connected and showing your usage data again too.
DIY steps to help with issues with your Home-Area Network (HAN)
Checked your online account and no ongoing smart meter communication issues to see? In this case it’s more likely to be an issue with the connection between the device itself and the smart meters (also known as the HAN). The In-Home Display connects to your smart meters via the communications hub attached to your electricity meter, so it sometimes helps to move your IHD closer to your electricity meter to help it re-gain connection. It’s best to leave the IHD in this new spot and try re-booting the device after 24 hours (a classic turning off and on again move), sometimes this simple step will do the trick.
Contacting our Support Team
Can’t get things back on track with the above steps? Not to worry - our Support Team can help get the issue escalated to our Smart metering team for further investigations.
Before you get in touch it’s best to complete the following IHD health check so we can make sure we’ve got all the information we need to carrying out some remote processes to get the IHD re-connected:
-
Does the device show a correct time and date?
-
Is the WiFi symbol solid/flashing/not there?
-
Could you confirm the Device ID? (Long ID number on the bottom of device)
-
How far away from your electricity meter do you store your IHD? Are there any walls in between that could be blocking the signal?
-
What is the issue with your IHD? E.g. not showing electricity/gas usage, displays incorrect tariff, device is rebooting itself?
-
Please confirm if your device is an IHD3 (black all over) or IHD6 (black on the front and white on the back)
-
If your IHD is showing incorrect rates: what rates does your IHD currently show? Are the rates shown on the IHD higher or lower than your actual rates?
Your responses to these questions can be forwarded to our Support Team (we’d recommend via live chat which you can access at the bottom of this page) who’ll let you know the next steps.
Another way to check your usage
So long as we’re in communication with your smart meters themselves, don’t forget you can always keep an eye on your usage data by checking the ‘Usage’ pages of your online account, whilst we get the IHD issues sorted. Check out the great guide below for an introduction to the usage info you can see here:
