THTC credit meters change to Smart meter.
This is our present THTC RTS setup. The meters are in an access corridor, the consumer units within the flat. I booked a smart meter appointment and OVO’s sub turned up in December and said a smart meter instal was impossible, grumbled about lack of communication about the instal he was going to and was meant to make a report to OVO. It appears that was sketchy as when I asked OVO about it, it didnt seem to give much detail. The installer did say 10-20% of installations were similar. As nothing seemed to be happening I raised a complaint. I was then told OVO wanted me to at my expense instal blocks at the high rate consumer unit for them to connect to. When I asked for more detail they came back and said they couldn’t instal a smart meter but were working on a two meter solution which might have to be legacy meters. This of course leaves the issue that if they put in a simple time switch low rate meter the present 24/7 low rate feed to the panel heaters and upper immersion is restricted to the low rate timed hours, which is unacceptable. i spoke to a local electrical firm a ferry ride away who say the answer would be from OVO to supply a 5 port smart meter and for them , not OVO since they refuse to do it, to reroute the 24/7 feed to panel heaters etc to be fed from the high rate feed to the other consumer unit. They suggested getting them to do this wiring swap just before OVO appeared to do the meter change once I get a date. I hve put this to OVO and await a response.OVO have described themselves to me as a “meter operator” I don’t think this is how the Regulator would view them. I also asked OVO to clarify that they would bypass the RTS switch box when they put in the new meter and would not be expecting me to get another electrician visit. I wait a response, delayed as it sat in their resolutions department as my contact was on holiday. I would be interested to hear if the suggestion I have been given sounds the answer. I know our existing two meter setup is not unique as a neighbouring flat with two credit meters is the same. Are others having a similar unsatisfactory and slow experience. 30th June is getting close. I am aware that in the same building there are a fair number of THTC/RTS 5port prepayment meters but they are single not dual meter setups and are more modern than mine but not smart so will also need changed.

Trouble-shooting issues with your OVO Chameleon In-Home Display (IHD)Tutorial
Updated on 20/03/25 by Emmanuelle_OVO: 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 for over 5 days you may see this message on your home-screen: Exact wording may vary 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: Noticed an issue we haven’t covered above or need some more help carrying out these trouble-shooting steps? Comment below as we’ve got plenty of IHD community experts on hand to offer advice.
Smart Economy 10 - Just had new meter installed is it too early to worry if the tariffs are the right way round?
We had a smart meter installed on Tuesday to replace the old THTC setup with Smart Economy 10. Everything has gone well so far - pleasant engineer, neat installation, heaters and hot water coming on at the right times, correct tariffs showing on the IHD at the correct times. I've been waiting for the new meter to show on my account and today it popped up, though the old heating meter still shows as well, and both readings from the smart meter are currently being allocated to "anytime". I'm not too worried about that as I assume it will eventually sort itself out. What I'm wondering about is, on the meter itself TOU rate 1 is the peak rate and TOU rate 2 is the offpeak rate. But when I go to https://smartpaymapi.ovoenergy.com/orex/api/supply-points/account/<account number> I see that Tier 1 is labelled offpeak: "region":"_P","profileClass":"01","meterType":"S2ADE","mapId":"UPLD","lineLossFactorClassId":"100","registers":[{"tier":1,"clockingTimeId":532,"timeOfUseLabel":"offpeak","meterRegisterId":"1","timePatternRegime":532,"measurementQuantityId":"AI","switchedLoadIndicator":null,"meterRegisterMultiplier":1,"registerMappingCoefficient":"1"},{"tier":2,"clockingTimeId":533,"timeOfUseLabel":"peak","meterRegisterId":"2","timePatternRegime":533,"measurementQuantityId":"AI","switchedLoadIndicator":null,"meterRegisterMultiplier":1,"registerMappingCoefficient":"1"}],"start":"2007-12-31T00:00:00.000Z","end":null,"fuel":"Electricity","meterNoOfDigitsOrDials":5}, The readings API shows the readings for Tier 1 and Tier 2 matching what I see on the smart meter display (ie Tier 1 matches TOU Rate 1 ie peak, as it's by far the lower value): "readingDateTime":"2024-12-13T00:00:00","readingType":"SmartReading","fuel":"electricity","tiers":[{"meterRegisterReading":16.381,"registerTier":1},{"meterRegisterReading":145.138,"registerTier":2}]}, This looks to me like I'll be billed exactly the wrong way round, when billing catches up. Or am I reading this wrong? Should I be raising this with OVO already? I should say, thanks very much to everyone who's been contributing to the THTC/smart meter threads over the past year or so for keeping lurkers like me up to date with progress and helping us understand the process better!
Landis+Gyr E470 smart meter unofficial guide - How to tell if you've got the SMETS1 or SMETS2 versionTutorial
Updated on 13/03/25 by Emmanuelle_OVO: Landis+Gyr E470 smart meters - Your unofficial guide One of the great things with smart meters, is that there’s quite a good range of options out there for suppliers to pick from. I’m quite a fan of the Aclara SGM1300 and SGM1400 Series myself, as I think they’re really nice and easy to live with. But there’s a bunch of others too… One of the most common meter brands used in the UK, is Landis+Gyr (L+G). They’ve also been a very common brand in the UK for many years, and it used to be highly likely that at least one electric and/or gas meter in every street was an L+G model, and this continues with smart meters. But there is also a bit of an unfortunate - and somewhat unlucky - snag here. How does one tell a SMETS1 Landis+Gyr smart meter apart from a SMETS2 Landis+Gyr smart meter, when they apparently all just so happen to be the Landis+Gyr E470 and G370? On top of that… Can you even switch supplier and if so, would you even know if your smart meters would suddenly drop off the grid and lose their smart functions’? Don’t worry, your resident Master Blaster has some tips and advice. What does a SMETS1 Landis+Gyr E470 look like? Here’s an example of one installed by British Gas/Centrica: A SMETS1 Landis+Gyr E470 smart meter with Trilliant comms hub. Original image credit @Tedbarn . As an alternative angle, this is another image from the same thread: Original image credit @Jason Kovesdi The images above were originally posted in the thread below, which has some useful discussions: There’s also another type of SMETS1 Landis+Gyr E470 smart meter, that looks like this, which we’ll get to further down: Another type of SMETS1 meter. Notice the separate comms hub to the right... The common characteristic of the SMETS1 versions is that they have a separate Comms Hub next to the meter, such as the Trilliant SEAP-2001-V. If you have one of these, your gas meter will also be SMETS1 and is probably a Landis+Gyr G370. If I’ve got one of these, can I switch supplier without losing smart functionality? Unfortunately, I’ve got a bit of bad news there. To get the best info, I need to call in help from SmartMe, one of the resources we use here a lot. While the plan is to upgrade as many SMETS1 smart meters as possible to SMETS2 firmware and migrate them to the National Smart Meter Network via the Data Communications Company (DCC), it’s running a bit behind schedule at the time of writing. The latest details we have are that S1 L+G meters are planned to be migrated by September 2022, but this may still change. If you’ve change supplier in the meantime and your meter lost its Smart function, it should recover after this process completes. I’m with British Gas right now and they installed the meter, is that a problem? I’m really sorry to say that due to the fact British Gas/Centrica are using their own proprietary WAN that no other supplier can access, if you switch away from them now, your smart meter will almost certainly lose Smart functionality temporarily. Don’t let this put you off though! It simply means you’ll just have to put manual readings in for a bit. If the meters were installed by another supplier and are still SMETS1, they might still work fine with a few suppliers. Please check first! All of these meters are being included in the migration. Once DCC takes over control, British Gas won’t be involved anymore and your meters will work fine everywhere. Will these meters work with OVO? Not yet, but they will soon! OVO chose to go with Secure branded meters rather than L+G back in the SMETS1 days, so the only SMETS1 meters OVO can support are those from Secure. However, OVO has got full support for all SMETS2 meters and SMETS1 meters from any brand that have been upgraded to SMETS2 and migrated to DCC. My own Aclara SGM1311 (guide here) that I like to call Raichu is one such meter. Feel free to switch to OVO anyway if you wish. Once the meter starts working, you’ll be notified. What does a SMETS2 Landis+Gyr E470 look like? Good question! Here’s an example of one that was originally installed by EDF: A SMETS2 EDF Landis+Gyr E470 with Toshiba SKU1 Cellular Comms Hub. Original image credit @MajorSqueeze And here’s another one that looks slightly different. A Testing/Demo S2 L+G E470 with Testing/Demo Toshiba SKU1 Cellular Test Hub from OVO’s office. Image credit: OVO Energy​​​​ This particular one is actually a testing/demo unit that I think lives in one of OVO’s offices! But if you ignore the test references, it’s otherwise identical to the ones that are actually used. The only difference is that this exact one in the photo has a special Meter Serial Number which means it’s not allowed to be put into service. Pretty much all SMETS2 L+G E470 meters look a bit like these two, but might not have the supplier stickers - and definitely won’t have testing/demo references! They never have a black border around the display, and will always have one green and one grey button - but might not be in the same places. It’s important to note that there must be a comms hub bolted to the top of the meter for it to actually be an S2 meter. If yours has a blanking plate on top instead, you probably don’t have S2. Please see below for what that could mean. If you have one of these meters, the exact gas meter you have may vary. Will these meters work with any supplier? Yup! As the SMETS2 variant, these ones work freely with any supplier, even if you’re no longer with the one that installed the meters. The super edge case! Pre-SMETS E470! Do you have an E470 that looks a bit like this? The Legacy Era! Pre-SMETS L+G E470 If so I’m afraid I’ve got some bad news. Unfortunately, this one is a Pre-SMETS variant of the L+G E470 that just makes things even more confusing. If you have this variant, I’m afraid it’s neither SMETS1 nor SMETS2, sorry! Will these meters work with any supplier? Long story short version: Erm… Nope. It’s impossible to connect them to DCC or any SMETS infrastructure, so unfortunately they’re not actually proper Smart Meters per se. They don’t have a Comms Hub and ran on legacy systems that basically no longer exist so the comms are dead. If you have one of these, you’re probably eligible for a free upgrade to SMETS2. So why the same model number? That is a mystery we’ve yet to solve. Sorry! Perhaps L+G might tell you a few clues though. My meter looks like the S2 variant, but it's got a Trilliant comms hub! What does that mean? Is it something like this example by any chance? A “Frankenstein” Landis+Gyr E470 with SMETS1 Trilliant comms hubOriginal image credit @bgreenwood2000 . If so then yeah... That might be a problem. It's quite possible that you've got an edge case with a bit of a Frankenstein here. We've seen one example of what looked like an S2 E470 that had an S1 Trilliant SEAP-2001-V comms hub on it, which really does give a whole new definition to "SMETS1+". It certainly gave me a bit of a shock when I found out about these edge cases! These are actually S1 I’m afraid. If there’s no comms hub bolted to the top, it’s not an S2. Given that S1 meters are no longer installed, there's probably only a handful of edge cases like this. Unfortunately, if you've got an edge case like this, then I'm afraid all your meters and IHD will be running as if they were on a SMETS1 setup, even if the meters themselves may have looked like SMETS2 hardware. This means you cannot take advantage of all the benefits offered by having full S2 hardware and may struggle to keep things working if you switch supplier, but there is at least some good news. Thanks to the national upgrades which are taking place, Frankenstein edge cases like this should be able to get upgraded to S2 firmware and then migrated to DCC by September 2022, just like all other S1 L+G meters. While you'd still have edge case hardware, you'll at least regain the ability to keep things working if you change supplier. When is a Frankenstein Not a Frankenstein? When it really is an S2! Here’s another one to catch you out: An S2 L+G E470 with Toshiba SKU1 Cellular Comms Hub and weird Kaifa attachment bolted to the meter! Image credit @Blastoise186 This one might look like a Frankenstein Meter, but it’s actually an S2 Frankenstein that really is an S2 E470! The reason for this weird setup is because there wasn’t enough space for the comms hub to fit without moving other equipment, so this particular L+G E470 has a weird flat Kaifa attachment bolted to the meter and a cable then goes to the S2 Toshiba SKU1 Cellular Comms Hub. I’ve got this edge case! What does it mean for me? Well, I at least don’t have bad news. If you’ve got this exact edge case, you are still pure and proper S2 because the Comms Hub is ultimately still an S2 Comms Hub. This means you do benefit from all the perks of proper S2 hardware, albeit in a somewhat weird configuration. If you're unsure whether you've got a weird edge case like this however, please do feel free to ask us for advice here. If you include some snaps of your meters and IHD as well, we can take a look. :) And if you do happen to work for Landis+Gyr, we'd definitely be interested to know whether these weird Frankenstein meters can be converted to use S2 comms hubs! 🤣 I’m still confused about what I’ve got, can you help me figure this out? Sure! Feel free to reply on this thread with some photos of your meters and IHD if possible. Even if you’re not with OVO, we’re always happy to puzzle solve for everyone. Not got a forum account yet?

New dual tariff smart meter stopped recording night rate
Hello, we’ve recently (late Feb) had a dual tariff polyphase smart meter installed in response the RTS shutdown. We have two phases as we have underfloor heating, so it has been a long protracted affair in getting our old legacy meters replaced with an Economy 7 polyphase compatible smart meter. This was done back in February, credit where credit’s due, the three phase trained OVO engineer was brilliant. The meter signals the off peak period to our underfloor heating controller, this has worked correctly since the switch. Just to be on the safe side, we took daily readings from our old meters just before the switch and daily afterwards so have a good idea on our daily consumption and to check for constancy old/new. We have the Kaifa MA329B We’ve been away for a few days and returned home last night and realised our new smart meter has stopped recording usage on the T2 tariff register. Virtually all usage since we were away is on T1 only. This points to something being amiss. Points to note/events since we were away: 1. We had a planned power cut of 9 hours notified in advance by our DNO. 2. We had a second unplanned outage of c2 hours two days later 3. The IHD had a new message “Elec meter initialised” when we turned it on 4. We have new charge rates since 1 Apr (like others on a variable rate tariff). The IHD correctly reports the new E7 day tariff. 5. We did not get the 1 hour new tariff countdown on the IHD from 2300 last night. After 2400 the meter was still registering T1, it should have switched to T2. 6. Our underfloor heating failed to trigger on. 7. Our OVO account still correctly lists us being on Economy 7. This seems to point to a faulty meter or config as a result of the power outages perhaps?? Additionally our smart meter has only sent one pair of readings since installation, on 21 March which was the end of our last billing period, our account is listed as every 30 min for readings and settlement. This doesn’t sound right either. Any advice, knowledge or input would be really appreciated. Many thanks!
Old Economy 7 set up needing to be changed for the signal switch off in June
Hi everyone. My elderly parents are extremely clinically vulnerable (88 and 90, numerous health issues inc COPD, heart disease and lower leg amputation). I know the radio signal is being switched off and I need to ring and get them a smart meter fitted. I have been holding off as they still have their heating on full time, and I couldn’t risk anything going wrong/them being without heat for even 1 day. Now it’s warming up and they will be switching the heating off soon, I am ringing up to book an engineer appointment. I have enclosed some pics of the set up. This meter is decades old (they are the generation that if something worked, they just plodded on with it for years). They migrated from SSE to Ovo. They have an economy 7 set up I believe with an afternoon boost to their storage heathers (all electric house, no gas). They also have an economy 7 immersion heater which gets the same overnight and afternoon boost. My question is: is this a set up that can be switched over to smart meter or does anything have to change compared to how they have it now? I have calculated a whole previous years’ bills and bc they have the heating on for at least 7 months of the year, it is barely any different to what a single rate would cost. Their bills are broken into off peak rate, peak rate and heating rate (I input 3 sets of readings on the ovo website). Because they have storage heaters we need to be able to have overnight boost and afternoon boost. Thanks for reading :)
RTS meter change stopped due to asbestos
Trying to get mother-in-law's meter changed in anticipation of RTS switch-off.It started off complicated and it just seems to get worse from there on!Not sure where I am now. Mother-in-law has an apartment in a Churchill older peoples' building (about 30 similar apartments). Back in September 2024 I started with a phone call to book an appointment and was immediately hit with the question of tariff. I thought that I was just booking a meter change, not realising that I would have to pick an alternative to Superdeal. Anyway, after a bit of too-ing and fro-ing it seems that dumb night storage heaters will be best suited to Economy 10 and an appointment booked. It seemed straight forward enough, so only mother-in-law was there on the day of the appointment. However, it turns out that the OVO technician could not do the job. Mother-in-law was told that there was asbestos and it required a different team and approval from the leaseholder (Churchill) to sort that out. The OVO technician gave mother-in-law a form for the leaseholder to authorise the work. Once OVO had received the completed form, then OVO specialist team would contact to make a new appointment. Unfortunately, I never saw the form, so I do not know what it was. The form was sent through the leaseholder. In December 2024, When we hadn't heard anything from OVO I contacted them again and was told that these jobs were being coordinated and the team would get back in touch in late January. Today, not having heard anything for a while, I thought I better get back to OVO again. Now I am told that I have to go to our DNO (SSEN), but I don't know why, I thought that this was OVO's job. So, I am even more confused. This isn't what I originally understood and not sure what I am supposed to know about getting SSEN to remove OVO's meter and OVO to remove SSEN's fuse and who swaps the board? Am I missing something? If it is any help. The building was built and the meter cupboard installed in 1992 although the meter is dated 2001. The contents are simple; an incoming supply cable to a fuse, a tail-pair to an RTS meter and 2 tail-pairs out to 2 consumer units elsewhere (one for 24 hour circuits and one for off-peak heating circuits).
