Smart meters

Hello,Cannot top up on app or online keeps saying declined.  Is there a problem?

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)? 

Can't register on portal or app as have new smart meters installed in property just moved in, and the app and portal.require these things I dont have. Why didn't I get from engineer or in an email from ovo? I'm paying bill monthly, so they knew I didnt have a top up card, yet still asked me to use app. Frustrating. I noticed the gas isnt showing on the home display, is that because its not synced properly yet it doesnt let me choose it?

Hello. I received an email from OVO saying they think there is a problem with my gas smart metre. I assume it has been triggered by the fact our gas bill has dropped a lot. That is due to us having replaced a very poor front door where a lot of heat escaped. The thermostat was near it so it took a long time for the heat to get up to 19 degrees. Our daughter also stayed with us for a while and she would have four or five baths a week. Me and my wife just use a shower. With these two changes our bills have reduced dramatically. When I responded to the email by ringing the number given, 0330 102 7517, a message said that number no longer exists and to ring 0330 303 5063. After answering some “security” questions, including my date of birth, which I don’t remember ever telling OVO, I was put through to someone who started asking the same questions again. I then thought I was being scammed so I told the person this and hung up. How can I be sure I’m not being scammed and how can I genuin

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 sup

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 an

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. 

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!

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

Our Hot water tank no longer works since January this year (2026).Heating engineer checked the tank and said we must contact OVO because he reckoned OVO must have switched off our RTS signal. Twice we have explained as best we can on the phone to OVO our problem. In the first call to OVO customer services we were advised that the necessary software modifications had been made but if after 72 hours our normal Off-Peak service for the Immersion heated hot water tank still wasn’t working we should call the Technical department ( for which they gave us the phone number). After five days (well above 100 hours) the hot water tank still wasn’t working. We called OVO Technical department and were advised that everything was working at the OVO end. But how does this help if we still don’t have our hot water tank working? Can anyone suggest what to do now? 

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. 

Hello, So my plans when installing a 8kw solis hybrid inverter and 16kwh lifepo4 battery were not for export, just a protection for blackouts (the house now runs on UPS). It is also a first step to lower electricity expenses, as they will only grow when we get an ASHP. Eventually we may add some PV.  Our battery install is ready.  🙂Since our DNO uk power networks stated they would approve us to do 5kw export, taking the next step while it was all fresh seemed simpler.  I now have an export MPAN, actually with 8kw approved. Our smart meter is export-ready. But we do not have MCS nor flexorb (as I had no plan to export now, I saved the expense).  Is there an advantage to get MCS paperwork vs short-circuiting and setting up export to an utility operator that does not require it? Or is there anything to gain with MCS?  😉 

Hello!I wonder if anyone can tell me why IHD is saying gas disablement suspended?  

I currently have a peak/off peak smart meter with my current supplier for electricity with an  SSC  (Standard Settlement Configuration )  id 0939. Do anyone know is all electricity company suppliers must offer this ?  Thanks . Much appreciated

I keep getting invitations to get a smart meter and I really don’t want one is there a way to stop these invitations ? How do I make it clear to OVO that I dont want a smart meter ?

I have a smart meter and am on economy. 10 tariff. My electric underfloor heating and immersion are connected to the meter via a consumer unit connected to port 5 and the rest of the electric useage is via a separate consumer. unit connected to port 1. The meter switches correctly to energize port 5 at the proper times, and port 1 is energized 24  /7. My question is when the meter energizes port 5 and I am charged off peak rate is the energy being consumed via port 1 being charged at the off peak rate as well or is everything still split by the meter so 1 is only ever charged at peak and 5 is only charged at off peak or is everything charged at the off peak rate and then when 5 gets switched off as per tarrif the meter charges everything still on at peak?
