New IHD showing high levels of usage - is this right?




Hi, I had my smart meters installed yesterday lunchtime, this morning my IHD tells me I used a combined gas and electric totalling over £25!! there is no way this is correct. My daughter had a shower this evening for 5 minutes and the electric cost went up on the IHD by £5.....anyone else having these unusual readings? its worrying me as my bill is going to be massive!

Nothing useful so far but I see others are also experiencing incorrect tariffs in their In-House Displays.

My usage recorded by the IHD appears correct - just the money amount is out by a factor of 10.

 


There seems to be a massive silly bug in IHD units being supplied with 2nd gen SMETS2 smart meter installs. Even with the right tariff and kwh readings it fails at doing the basic maths to calculate the the cost.

For now, our one is just turned off until there's some kind of official announcement about how they're going to fix this daft bug.

 

*Update 18/11/2019: OVO have completed a firmware update on the first batch of members’ IHDs. This should fix the issue that meant the IHDs displayed incorrect usage figures.*

I've moved your post here, @tom.clements, there is plenty of handy information in the above thread. @PeterR1947 has hit the nail on the head, the meter and IHD needs a bit of time to fully sync up.

Thanks!

Tom, it can take two weeks or more before your meter is properly connected and providing the correct readings, there’s a complex process to go through which you can have a link to if you wish.

mt smart meter installer showed me how to read the current reading on the ihd the reading on the display is vastly different to the smart reads shown on my account which show 00000 as of yesterday (18/9 with no read taken today 19/9
the meter was installed yesterday

I've moved your post here, @Revstar, see the above best answer and the large thread for more info!

Smart meter installed yesterday, was told about all the virtues of tracking real time usage and costs being displayed based on my actual tariff.

Looking at the IHD its reporting that in the middle of summer (so no heating) on a day where the only gas usage was the boiler heating the hot water cylinder for less than an hour - which has cost nearly £9.

Just seems totally inaccurate. It’s worrying because I now don’t know what to expect on my bills.

My typical usage for total usage in summer (may to sept) for both fuels is c.£2 per day
Seem to have a follower 😂
I will be plain, I fit Smart meters and come across all that that entails, I'm not claiming to be a professor of Smart meter workings, I give what I know, have experienced, and others have passed on in my field, and I work with some top engineers.
I've read back what I wrote and it seems quite easy to follow I think,....any advice or help I try to give on here is in good faith. In this instance it relates to some of the problems ovo customers have been encountering with ihds.... Maybe.... Its something I added to the conversation because a manual reset is required on the ihds we install, and funnily enough are the same as ovos

I don't follow that @Tufty71 🤔

Which previous post are you referring to when you say that it's worth noting as well?
As well as what...?

I can't find anything on this Topic where anyone was discussing an IHD failing to pick up data that was being (correctly) transmitted across the HAN.

If the meters are communicating with the Comms Hub, then that's the source of data which gets sent to the IHD.

I've received several code updates sent to my SMETS2 Comms Hub in the last 5 weeks. These have changed the values which are displayed on the Chameleon IHD. However, the process occurs without intervention. There's no reset required.

How could an IHD be picking up an earlier set of data such that it required resetting in order to now get it correct?
What's also worth noting as well, is the ihd may not reset itself. Once commissioned on the secure (smets 1) meter set up, it would auto turn off and immediately back on to reset, on the smets 2 set up, the ihd needs manually turning off and on.... So even though the meters might have been commissioned in that period of time after an engineer has been, you probably will have to do a manual reset (on/off) for you to get proper recorded energy consumption on your in house display
Thanks for that update @Mja. The LED flash sequence is what I expected... unfortunately.

From my viewpoint, it's a pity there isn't an LED indicator which specifically reports the status of communication with the SMETS2 Electricity Meter
below the Communications Hub

. I can understand why it's omitted because the two units are physically interconnected via the ICHI (Intimate Communications Hub Interface).

It's going to be even more tricky to diagnose problems with SMETS2 meters
in the Northern territory. Those Comms Hubs

have only two LED indicators, either of which can flash green or red. I'll try and build a similar "Customer Guide" for those too.


The meters in the North and central North do indeed carry the Same communication hub, and yes its a two light system on the hub, han and wan, if it's red it will be solid and you have a problem🙄 but the green lights you see flash at varying rates dependant on state of connection etc so that can tell you all you need to know, as long as you know what they mean 😁
Ahhh you're the brains, 😁.
As far as commissioning its possible, maybe not as far how OvO fit Smart but it definitely can be done 😉

☺ me a meter-fitter, eh?

Sorry, no @Tufty71 . I don't work in the energy industry. @tony1tf and I have met when visiting OVO at the beginning of June. And he will probably recall that I work as a builder/designer.

I'm afraid that's not possible @Tufty71. The Installation work on site does as much of the commissioning as can be achieved at that time. The four devices (or three if gas isn't used) are paired with each other, and checks are made to ensure that there is a viable link between the Communications Hub and OVO's SMETS2 team.

This link is not direct, but first via the WAN provider (Arqiva or Telefonica) and thence through DCC. At that stage the signals are using a bare minimum of encryption.

Once OVO have verified that the link is operational, DCC take over the next stage of the Commissioning Process. They, and not OVO, own the Comms Hub.

Only in the final stages of the process will DCC send the necessary ID numbers to OVO which allow them to start running and configuring the SMETS2 meter components themselves. This includes downloading the customer's tariff info and changing the data stream to match the input required by their in-house billing system.

This procedure has taken years to establish and agree contracts across all parties. It is enshrined in the regulatory framework and has been verified by GCHQ to ensure that it is secure. It should never be possible for someone to arrive on-site and fully commission a meter onto the National Smart Meter Network.
Hi @Transparent

Where are you getting your info on parts like the ICHI (Intimate Communications Hub Interface)? You seem to have so much more knowledge than all of OVO combined ;-)
Although I just Googled it, and now realise that the info from the DCC is the first hit. However, I presume you do have to know it's exact name to get that instant hit.

Tony

Sounds like a meter fitter to me, spy in the camp 😉
Really surprising this isn't proactively explained to people having new installations, the amount of traffic on here would go down thats for sure and it would alleviate the worry some people may feel.

Update on the behaviour of my IHD is the displayed gas £usage is incredibly low and displayed electricity £usage is still incredibly high. When I look at the IHD sometimes it says waiting for data, sometimes it doesn't. The explanation of the IHD needing 4-6 weeks to sync will hopefully resolve it.


Just a few small steps and ovo could really improve customer experience when having smart meters installed, it appears to me they are rushing the process.
All these problems boil down to the fact Ovo engineers do not commission the meters on site.
The meters are installed but the commissioning is done at a later date remotely, so there will be delays in the meters working properly, and until commissioned they are not showing correct usage, tariffs, etc
Really to stop all this confusion and aggravation Ovo should be looking at commissioning on site.

Thanks for the update @Mleeson

Firstly, you don't have a "mesh problem"!

88% of Comms Hubs in the Southern & Central Territories don't have any need for a Mesh network. Your Comms Hub is operating just fine with the modified 3G network operated by Telefonica. That's why the WAN indicator is flashing.

Secondly, you should definitely email hello@ovoenergy.com to report the loss of SMETS2 electricity readings. Try to give as clear a set of symptoms as possible so that @Darran_OVO can also alert Ben for further investigation.

When was the SMETS2 installation date?

Have you made any changes to your energy requirements on or around 13th July, such as installing PV panels, or a heat pump on Economy-7?
May I just jump in and clarify what @Eva_OVO has written?

@Mick85, @Mleeson and @Mja - the issue with erroneous readings on the Chameleon IHDs

has been clarified by OVO

yesterday. The software bug is in the Communications Hub

which sits on top of your SMETS2 Electricity Meter

, rather than the IHD

itself. See what I posted here on this other Topic yesterday, and the following message from @Darran_OVO where he explains why he edited what I'd just posted.

This is actually somewhat of a relief. Unlike the IHDs
, the Comms Hubs

can have their software upgraded remotely without a site visit. So when OVO

have finished testing the new code, it will be uploaded directly.

Dealing now solely with the points made by @Mleeson and @Mja , do I understand correctly that you both have gas meter readings showing on your IHD

, but not electricity?

Do you see the same when you log in to your My OVO account page?

If so, could you please fill out your Forum Profile pages? I'm looking for details like the area of the country you live in, and whether you have PV solar panels
etc.

Thanks.


Hi @Transparent,

Apologies for the delay in my reply and thanks for your help! I have now also updated my profile and can confirm that you are correct in that my IHD is showing my gas readings, but not electricity. I also haven't had electricity meter readings registered on MyOVO since 14th July.

I can also confirm that similarly to @Mja my Comms Hub is a Toshiba variant and all lights except 'mesh' are flashing green every few seconds.

I hope this information is of some use?

@Darran_OVO In relation to the lack of electricity meter readings being submitted to OVO and the 'mesh' issue with my Comma Hub, can you confirm whether it would be best to query this via Facebook/Twitter, or via email to hello@ovoenergy.com. I receive the online account management discount, so do not want to jeopardise this!

Thanks,


Matt

Hah, @tony1tf Do you want me to divulge all my sources?! 🙊

Yes, DCC's own website is an absolute treasure trove of useful documents. But you do need to be careful that you're reading those that are currently "live" as opposed to Proposals or Position Statements whilst the Smart Meter system was being developed.

There's a whole page of documents about Communication Hubs, and a link on the right hand side which takes you to information about the ICHI in particular. The level of detail is excellent:



Fortuitously, I can speed-read technical documents. So, yes, I have actually read all of DCC's library of "live" documents about SMETS2 meters and Comms Hubs!

Beware too, that just because a feature is specified in a "Final" document, doesn't mean that it is an available function at the moment. It's possible that the current iteration of the software leaves it inactive until a future firmware upgrade. As we learned on Monday when we met at OVO's HQ, that seems to be the reason why you don't get data from your SMETS2 electricity meter.

I'm sure I don't know more than OVO. They have whole teams working on SMETS2. But of course, each team member concentrates on particular aspects of the work.

Thanks @Mja great to get this feedback, I have forwarded it onto Ben who's leading on the SMET2 testing. We run continuous testing even after rollout, as this is still very new technology so impossible to iron out all the kinks before go live, but we hope to react as quickly as we can to get them resolved.

And thanks to @Somerpark for sharing the Bulb experience, good to know its a wider challenge than just some of the issues we are seeing. You can read about Bulb's issues here.

Ben has been actively reading all the posts relating to SMET2 so is finding all this feedback super useful. Keep it coming and we will ensure we remain focused on getting any issues resolved as quickly as we can.

@Transparent mine is the toshiba hub and all LEDs are flashing other than mesh, uniformly every couple of seconds.

Thanks @Mja.

Fortuitously I was at OVO's Bristol HQ on Monday. So although I'm just a fellow customer like you, I was able to speak with members of the SMETS2 Team. I'm gradually piecing together some background information on a number of faults and quirks with recent Smart Meter installations.

Yes, you should definitely make contact with OVO directly about the loss of your electricity data. This is a completely separate issue to the "IHD erroneous readings" problem. I suggest that you email to hello@ovoenergy.com so that you retain a time/date stamped copy of what you've reported.

I know of one other person with a SMETS2 meter installation which has lost electricity data whilst gas data is still active. However, what you've just written in your Profile tells me that you have different symptoms.

Can you have a look at the message I wrote on this other Topic where I put diagrams of the flashing LEDs on the Toshiba Communications Hub?

What LEDs are flashing at what rates on your Comms Hub?

If you're still unclear on any of this, please ask again.

@Transparent , my meter install was May 24th, initially only electric showed on the IHD, gas came along after a couple of days, engineer said this would be the case. However, the usage cost displays were clearly incorrect, electricity too high, gas too low.

IHD is now only showing Gas and has been that way for a couple of weeks, which makes sense in that June 5th is last Electricity reading in MyOvo account. I will update my forum profile as suggested.

@Eva_OVO I see that you have advised @Mleeson to contact Ovo to report problems. I was advised to do the same when I came to the forum to discuss the cost display issues, the response was the same as the reponse we got on here, issues that would resolve after 4-6 week sync. Should I contact Ovo again now that I have the additional issue of the electricity not being displayed? The confusing thing is the initial advise that the IHDs has a fault (the cost display) but @Transparent‘s post is pointing at bugs in the meter comms hub.

Obvious question is this all one issue or are there separate issues with the IHD and Comms Hub?
