Smart meters

My hot water and storage heaters work on Economy 7 so the meter should switch the electric supply on around midnight and switch them off around 7am.  It worked perfectly until I had a new smart meter fitted in March this year.  Ovo tell me it the new smart meter is programmed correctly on Economy 7.  However when I look at the hourly graphs I can see that it switches on at 4,30am for 3 hours, 2.30 pm for 3 hours and then 8.30pm for 3 hours.  None of this is overnight when my off-peak rates apply.Is this even possible? 

Hi, we are having a bit of a saga here, about a month ago our water immersion heater that works on the economy 7 stopped working. We’ve had various plumbers and electricians at it and it’s still not working, but one of them suggested that we try and see if our storage heaters (which had been turned off for a while) were working. The storage heaters didn’t work either, so having tested everything he came to the conclusion that the problem must lie with the electricity meter. It’s an old one, probably still the original from when the apartments were built 25/30 years ago I think. The electrician said he was fairly sure that a smart meter would not work here, as we are in an apartment block. Have called OVO today to ask for someone to come and have a look at it. They were very insistent on booking an appointment to install a smart meter, which has duly been made, but will it work? And if, as seems likely, they can’t get a smart meter to work in my flat, what is my next possible course of

Will the engineer test to see if a smart meter will be able to receive a signal before installation.   A 4 or 5 years ago a meter was installed that could not receive a signal

Hi. I am a bit concerned that, even though I have a smart meter, someone from Morrisons called to read my meter. I thought having a smart meter obviated having someone call to the house. Fortunately my daughter was at my house at the time as, if I had been on my own, it would have made me very uncomfortable.

Does anyone know why my Aclara SMETS2 will stop working properly on 1st June 2026 and needs replacing?  It’s new and was only installed in April 2025. 

Hi, we are in the Scottish Highlands and have been told we cannot currently have the THTC replaced by a smart meter due to signal issues, OVO currently have no alternative so we have been left with a fuzzy answer that they may have a solution in two months time. Any body else have any additional information, my communication with OVO has been through the online chat box, although with an actual person

A man knocked this morning claiming to be from OVO and wanting to read my smart electric meter. I told him they are not manually read. He said they have to be manually read at least once a year. I said that was not so. Who was he? Who sent him?

Booked a smart meter installation several months ago and an engineer turned up for the appointment. After an initial survey he advised that smart meters could not be fitted in my house because the existing meters were not separated. He then advised that a kit was available to sort this problem but to date I’ve had no follow up. can anyone advise?. Clive

Hi,I have just moved into a newbuild apartment where the utilities have been handed over from the developer. The current meter reading is 03552 (shown by the photo), slightly above the confirmed reading I received off the developer on completion.I registered with OVO Energy this week and found out from them that my meter is apparently a smart meter. However, upon checking the readings it has sent to OVO (photo also attached)  they appear to be completely different and far lower than the reading I see on the meter.Is it possible this is fine and it sends different readings from the display I see when reporting as a smart meter, or is there something potentially wrong with my electric meter/out of sync and I need to call ASAP. 

My 88 year old Mother, lives alone and spends most of the night awake watching TV, drinking tea, etc.However, EVERY single day her half hour readings show 0 ZERO usage from exactly midnight to exactly 7:00am.Ovo are saying their meter readings are right.My argument is that if you drove your car a distance that you know for sure is 10 miles, but your odometer said it was 50 miles… then you are saying that the odometer must be right as that is what the odometer says !!!My 88yo Mum does not race around the house and turn off absolutely everything at midnight, then 7 hours later race around and turn everything on.It would be funny if Ovo weren’t predicting she will use over 13000 KWH for the year !!Anyone with any insights ?   

We’re both in our 80’s with health problems and I would like to know how much preparation we have to do before we get our meter changed. The backboard is screwed to the outside wall close to the ceiling (it’s an overhead supply) and during a kitchen refit a cupboard was built around it.  To get at this cupboard, the free-standing gas cooker will need to be moved and the engineer will have to stand on a work-top and possibly dismantle part of the cupboard.  Will they move the cooker (we can’t do it), and will they repair the cupoard if they have to dismantle it?  At our age and with our health, we can’t do it.Any other tips on what we might need to do would be welcome.  We didn’t want a smart meter, but it’s being forced on us because apparently the certification has run out on the old one. (any ways of getting round this?)Thanks in advance!

Hi,Since moving to OVO from EDF on Jan 5th, the Geo Trio II IHD supplied by EDF will not connect to the SMETS2 smart meter also supplied by EDF.Even after resetting, it just sits there and say trying to connect. There appears to be a strong 5 bar WiFi signal and the IHD is less than 2 metres from the smart meter with no obstructions in between.When I look at the IHD the screen says      Meter Network Not Connected             Status 22-0      Not connected to meter network. If the problem persists, please contact your supplier.I have contacted OVO support and answered their initial questions but they also suggest seeking help here on the forum.Any ideas ?thanks and regards, Kevin  

We’ve had a long-running issue with Gas Smart Meter readings (SMETS2) not being recorded on our account, and our IHD doesn’t show any gas usage. We had an AltHAN setup installed with a Landis+Gyr B1 installed at the meter and a B2 installed close to the Gas Meter. The Gas Meter is probably 10-15m away from the SMETS2 Electricity Meter.  This worked for about 14 days, then just stopped again. The Gas Meter HAN status shows as “Offline - Waiting for next retry”. The B1 & B2 have a RED “P”. See photos. I’ve power-cycled the B2, but with the same result.  I can’t find any documentation for the B1/B2. A few questions:What do the status LEDs mean on the B1 and B2? From the photos attached, can we deduce anything? What do the reset buttons on the B1 and B2 do? Can you manually reset them by using these? Are there any techniques to resolve the issue at home before calling OVO again (this will be the fifth visit)? Thanks.   

Hi! I've got my smart meter yesterday but something went wrong and my boiler is not working. It's Friday night and I have no hot water until the next week???

HelloApologies, but I cannot give as full details as I would like, because it is difficult to use a computer owing to ill health.I stay in a council house in Scotland and am affected by the RTS switch off. I arranged for a smart metre to be installed in February 2025. Unfortunately the job could not be done because the fuse box is too near the piece of equipment that needs to be replaced.For the last 14 months I have been trying my best to get the council to do the job but to no avail. At one point I was told it was just awaiting scheduling. Over the past few weeks I have even tried contacting my local councillors and even they are not replying.Today I received an email from Ovo telling me to arrange a smart metre installation because the switch of date is now 02/06/26. How reliable is this date?We cannot lose our heating because the household is made up of an elderly person and a disabled person.Any advice?Thanks

Okay, here goes... Smart meters installed in June 2019, except they weren't commissioned until January 2020. Since then my meter readings are being sent hourly to OVO and my usage is visible online after 24 hours, but my IHD is only showing gas usage. I've asked the email team , about showing electricity usage on the IHD and after 16 days advised that they'd requested my IHD's firmware to be refreshed and I should wait 48 hours and turn my IHD off and on. I've tried this but after 3 days nothing has changed and I'm looking to try and resolve this before the anniversary of the installation (although maybe I'll get a prize for the longest smart meter installation?) Can anyone suggest a solution? Many thanks  

Hi everyone,My old prepayment meter has gone into fail safe mode, and it’s neigh impossible to arrange replacement (it’ll be a smart meter) as it’s on a shared fuse. I’m looking for advice on who’s responsible for what, and what my opetions are to get out of this mess. Here’s how my issue unfolded:January: supllier’s engineer came to replace the meter, but abandoned job due to the shared fuse. we contacted the DNO (from my phone), the engineer asked for my supply to be unlooped. February: DNO (SP Energy Networks,  Scotlland) replied that they ’don’t see a strong reason to unloop’ and that my supplier should organise power outage with the neighbours. My supplier asked me to organise outage with the neighbours.  I tried, but failed to get hold of anyone next door. I asked my supplier to organise safe isolation or unlooping with the DNO. They said they will ask their meter operator, but answer is still pending. March: My supplier sent an unannounced Revenue Protection people (haste ldt),

Why is there no option to change my smart meter installation date online? Despite their text massage saying I would be able to change it online. It’s Saturday and I want to change my appointment from Monday to Tuesday, but if the only option is to phone them then I can’t do that until Monday morning since the phone lines are closed at weekends, which is less than 24 hours notice, and hence a  £30 fine. 

Hi,We had a smart meter installed a few years ago and it has never been able to send readings automatically.  It is a Aclara 1411-B SMETS S2. The engineer said that it was due to poor wifi/mobile signal.Since it was fitted, we have moved onto ‘superfast’ fibre wifi and the mobile signal has been significantly improved but the meter is still not communicating.  I have completed the ‘healthcheck’ and see no reason (WAN is flashing every 5 secs and the HEB is on constantly) We want to look at changing our car for an electric or plug-in hybred but there is no point if the SMART meter is not working.  How can we ‘restart’ comms ?Any suggestions much appreciated.

 Updated on 17/04/26 by Abby_OVO The great things about In-Home Displays, also known as IHDs, is that they're very useful little gadgets that can show you your energy usage in real-time, but unfortunately it’s all too often that your dog knocks it off the coffee table (a dogs wagging tail can swipe just about anything in range!), you spilled coffee on it or worst of all… It grows legs and vanishes when the previous householder moves out. 😞 So what can you do if you're in need of a new IHD or just fancy a spare one? Read on to find out!  Introduction and acknowledgement  But first, I’d like to introduce myself. I’m Blastoise186, one of the forum volunteers who helps out on the OVO Forum. With over 18 months of experience and two Chameleon IHD6 (named the Kecleon Brothers) to play with, I’ve learned a lot about how these devices work and many of the quirks of using them. I see a lot of questions across multiple forums about how to get a replacement IHD if yours breaks or goes missing, s

I’m trying to register with a third party to access my usage data. They ask for the MPAN (which is fine) and the MAC Address of the IHD.I’ve entered the MAC Address from the IHD I have here, but it’s getting declined. Just tried to explain this to OVO, which resulted in me being told my IHD no longer works (it does) and I can only access my usage data using the OVO App.Pulling my hair out with these folks at the moment. Does anyone have any suggestions?

Hello,What does “-A” mean in front of the meter reading ?We do have solar panels, is it something to do with that?Thank you for any help.Phil.

Have recently had solar panels installed and although I can check how much I am exporting via the main electricity smart meter I cannot see how I can see this info on my smart meter display - apparently I should see a pylon icon - have I got an old display (photo attached). Thanks. 

Eon put in a new smart meter in September 2025. We only have electricitry.  We have a tarriff with Peak and Off-Peak times.  We have an ongoing suitation where Eon constantly reverse the reading/unit cost by either sending us statements where the Peak use is actually the Off-Peak and the Off-Peak use is given as Peak use or the statements show the correct Peak and Off-Peak use but then charge us the wrong rate. They have now asked us to send photos of the meter taking “ spaced reads tests ...about an hour apart”.  I have asked why. My understanding is that with a smart meter the company can see any use at any time, possibly as frequently as every half hour. They also know what tarriff we are on  so wat added benefit will photos be ?I would appreiate any thoughts as to why Eon are seeking photos when they have the information at their finger tips.Thanks
