Constant Blue Light on IHD a Malfunction?

We have recently moved supplierĀ and have electricity on a credit tariff and our gas on PAYG. Usually the meter will show the standard three usage lights Green/ Amber and Red to show our energy usage, but all of a sudden it has lately being switching to a solid blue light (see image below) and the only way to return it to the standard usage lights, is to reboot the IHD, but his only works for a day or two before the blue light comes back.

Ā 

Is this a fault with the IHD? As you can see, it is still the same IHD that came with the original smart meter that we had installed (and still have) when we switched to a smart meter with our old supplierĀ

HeyĀ @NotQuiteAlice,

Ā 

Welcome to the OVO Online Community,

Ā 

I looked into this for you and couldn’t find information about what blue means specifically. I think that it may be, as BPLightog suggested to do with a budget. When you move across from your old supplier the IHD may switch back to factory settings. Before it ā€˜re-learns’ your usage patterns.

Ā 

If you have any further clarity or updates on this please report backĀ šŸ™‚

Hi @NotQuiteAliceĀ , normally a blue light indicates a gas only supply although here I can see your electric usage andĀ icon as well.Ā 
Might there be a budget set for gas usage which needs adjusting?

I don't think I ever messed around with the budget settings, and to be honest, I wouldn't even know where to begin.

The one thing I have noticed is this morning it has gone back to the standardĀ Green/Ā AmberĀ andĀ Red, showing our energy usage.

What I am thinking is that perhaps the blue indicator is a newish function to show when someone is in the eco zone of their power plan, you know, when it’s the best times to use washing machines etc. It does seem to go blue after 9pm (ish), I will monitor it tonight and see if it does it again.

Mine has also gone blue the last few days and I've not moved supplier or changed any budgets or even touched it! It doesn't change either when I put the kettle on.

Therefore I think you might be right in saying it's something to do with the time of day. I'll watch mine too šŸ˜„

Mine has gone blue now and I cannot do anything to reset to energy level colours. We only have electricity and the meter installation was 7 years ago. FritheeĀ

As you were, as they say in the Army. I rebooted again by switching on and off and bingo! Energy level lights are back.Ā

Smart meter is sending regular readings but light is constantly showing blue

Hey ​@RobertsĀ 

Welcome to the OVO Online Community 😊

Are you able to add a photo of the meter to this topic & we can take a look?

I know someone who may know … ​@Blastoise186Ā

Heya!

That sounds like you’re looking at an IHD to me - Smart Meters themselves don’t have blue lights.

Please show me the one you’re looking at.

Ah yeah, an IHDL SmartView… Not seen one of those for a while…

What you’re seeing is expected behaviour because no usage levels are configured right now. Either that, or gas usage is showing. One or the other

Thanks for the reply.Ā  It appears readings are being recrived for gas and electric.Ā  Do I need to request a replacement or will it correct itself?

No need. It’s not really a big deal - the meters themselves are doing the heavy lifting anyway, not that IHD.

You can if you want though!

Morning ​@Roberts,

Ā 

I hope you had a good weekend, and thanks ​@Blastoise186Ā for your great answers here 😁.

Ā 

​@RobertsĀ I just want to add that, if you haven’t already logged in to your online account or app yet we’d recommend it, as you’ll be able to monitor the ā€˜Usage’ pages and graphs, which actually give a more detailed view of your energy consumption than you’ll get with your IHD. You can find out more in this Forum page:

Ā 

Ā 

The above article will tell you how to view the ā€˜Usage’ pages, and also contains links for other pages that tell you how to how to choose how often your smart meters send us readingsĀ (you’ll need the smart meter(s) set up to give half-hourly reads to see the most detailed usage breakdown.

Ā 

You can also find more info, guides and videos for your type of IHD on the In Home Displays website.

Ā 

I hope this helps!
