Title: Electricity Smart Meter
Post by: Martin109 on May 22, 2019, 02:53:35 pm
I am considering having one of these fitted, perhaps reviewing my scepticism, as I had previously thought that such a unit would be connected to my broadband, thus involving me in the 'internet of things', which I view with mistrust.  However, the lady from the electricity people said they send data direct to themselves.  How does this happen?  Was I naive to think broadband was involved?  Sometimes I'm a bear of very little brain.

Beware the smart people speak with forked tongue.  Worth asking Mr Google a few questions as there are loads of issues floating around:  not compatible if you want to change supplier; simply does not work etc. - especially the network transmission.   

And of course the "it'll save you money" is a bit devious .... what it does is show you how much energy you are using -  and for you to turn it down and save money.

The bit about reading your meters (or not having to) which is a benefit - is easily solved as quite a few of the energy companies have a website/app for you to read meters and send figures to get actual bills (I pop out to my garage once a month, smartphone in hand, to read the meters and by the time I get back in the house I have an email from British Gas with the reading and the amount.)

My advice would be to wait for a while (probably quite a long one)

It is not much data. If it just needs to send your current meter reading, it should only be about 1KB each time. So maybe 50MB a month, which doesn't cost much. Much cheaper than sending a person round to read the meter.

In the northern half of the UK, it is using a separate network. So it doesn't use the mobile signal anyway.

The smart meters also have a separate "home area network". They use this to transmit from the meter to a home display. This is based on Zigbee, so separate from any home wifi you use.

I'm looking at getting one installed but only after I've been assured that they are the second generation so don't go dumb when you switch supplier (which I used to do a lot, but have not needed to of late). In the installation questionnaire that they sent me, they did mention issues if your gas and elec meters are more than 10m apart (which most aren't) and some old meters are not compatible.
In terms of saving money, I agree with the above, but I'm looking at possibly going on a tariff with the same supplier who takes readings regular readings for differential day/night pricing, which may save us money (no switching anything on until after midnight! dinner at 1am, and showers before 6am!)

We don't have a smart meter.  A little while ago when I was investigating who to switch to I noticed that some providers were requiring a sm with a new deal.  I spoke to one major company to ask if the Smart meters were SMETS2, and they said they were rolling them out but not in all areas, so could not guarantee we wouldn't end up with a SMETS1.  In the end went with a provider which didn't have any sm clause.  Apparently... https://www.telegraph.co.uk/news/2019/05/14/two-million-smart-meters-not-working-research-suggests/  (...in 'dumb' mode.)

As has been said above the 'no more estimated bills' bit adds no value as you just submit your own readings when required.

Flexible tariffs and load shifting will help consumers to save money if they work at it, but not all suppliers offer these.

Submitting your own readings will ultimately at some point require a validated reading.
Taking photos of the meter with some sort of unique tamper proof identifier attached would be the non-smart way of doing similar to the smart meter in terms of billing which is providing the supplier with a validated figure of usage.

.. yep, the validated reading is OK - but we get gas and electric from British Gas (and read the meters etc each month) - but we've had the meters read in the last month by, guess what, two different meter reading persons on behalf of our single supplier!

Well, it's their bill, not yours. They either use GSM or mesh with nearby meters until they find a suitable GSM link. It's not much information and they're not paying by the gigabyte, it's a dedicated system.

I'm not against them because I'm lazy and reading the meter means squirrelling in the dark cupboard of wires under the stairs and it'd be interesting to see what we're actually using rather than getting the bill and thinking 'how fucking much?'

But I've not bothered because the customer services at British Gas couldn't tell me whether we'd get the old or newer smart meters (well, they didn't know they were two sorts) and I can't be arsed having them fitted twice when we eventually get annoyed enough with BG to move.

Which is exactly why I've just told Scottish Power to get stuffed, when they wanted to know why I'd declined their kind offer to have an SM fitted.  I read the meters every quarter and email them the data - takes all of 5 mins. I have a monitor on the hall wall next to the kitchen door so I can immediately see when SWMBO has left on something she should not have, and I can send the naughty schoolgirl upstairs to turn off the fan heater in the music room.

I was constructive in my response: when you can guarantee an SM2 meter, and that the data comms will work, you can fit a meter.  No?  Thought not. Sod off then.

I'm liking our not-that-smart smart meters because they mean I don't have to play bike-and-camping-kit Sokoban in order to read the meters.  Which means we pay for what we use, rather than what the random number generator comes up with, and fewer dodgy blokes turning up at awkward times expecting us to do some spontaneous heavy lifting.  (Or worse, damaging bikes by attempting it themselves, when I'm not in and barakta isn't capable.)

A secondary benefit is knowing what we're using.  Not because of the smart display unit thing (which is very cumulative-money-oriented and largely a waste of electrons) but because unlike our previous meter, this one has a blinkenlight on the front which I can easily interface to a microcontroller using a phototransistor and a Mk 1 bit of blutac, and generate much more informative time-series data.  You can infer a lot more from a graph like this (https://yacf.co.uk/forum/index.php?topic=80102.msg2315671#msg2315671) than you can from an instantaneous power reading, unless you actually want to run around switching things off.

Obviously dumb meters with blinkenlights are available.  But not predictably.
Title: Re: Electricity Smart Meter
Post by: Wombat on May 24, 2019, 05:59:28 pm
All reasonably modern meters, regardless of smartery, have blinkenlights.  There are some aftermarket displays that read said blinkenlights.  Both our import and export meters have these, but of course they are in different places, which is not helpful. the import meter is (surprise) in the meter cupboard, but as the export meter (which is absolutely identical to the import one) is mine, not theirs, its not allowed in their box.  I do know exactly how much I'm currently generating, and a daily/monthly/annual record of generation wherever I am in the world, but can I find out how much I'm using, or have used today, no I bloody can't! Thanks, you fumbling arseholes of the Energy Retail Association who completely fumbled the standards for smart meters, meaning I can't have one...
Title: Re: Electricity Smart Meter
Post by: Wombat on May 25, 2019, 06:59:43 pm
And as a follow-on to this, I received my electricity bill (online) and thought that the cheapest tariff that I'm on seemed to be more expensive than the standard tariff that I was on temporarily.  So I had a whinge at SSE, also about still having my address wrong, then went back online to change my tariff to the new cheapest one.  All went very simply, got a message that I was now on the new tariff, with a footnote under "what happens next".  It said this tariff means you need to have a smart meter.  Go on then, give me one, as I've asked for one half a dozen times and you keep telling me I can't have one because I'm awkward enough to have solar PV.  This could be mildly interesting, as I'd like to see them try to tell me I can't have the cheapest tariff because they are too bloody incompetent to give me a smart meter...  I do like a bit of sport with some organisations.
Title: Re: Electricity Smart Meter
Post by: Wombat on November 16, 2019, 11:18:09 am
Well, that was fun... or not.

In August I eventually got a date for an installation of a new shiny SMETS2 smart meter, that can cope with me having solar PV.  The date was Tuesday 12th November, and they kept sending me phone messages twice a week since August, reminding me of the installation date, including one sent the day before the installation.

Well, do you think I now have a smart meter, it being the 16th of November?  Of course I bloody haven't, because they found a new way to screw up. 

Apparently the mobile phone signal isn't reliable enough without a 5 metre high aerial which they don't want to provide.  Actually where the meter is, there is a fairly consistent Vodafone signal, but of course they use EE.  So why did they only realise this the morning of the appointment?  The head of customer services insists its because they do repeated phone signal checks (how, without actually visiting my house?) right up the the installation time.

They say I will probably have to wait a year or so to see if the phone signal improves, but as the phone companies seem hellbent on providing 5G to city dwellers who already have pretty damn fast 4G, rather than actually providing a phone network that serves the whole UK, I'm not holding my breath.

So why didn't the smart metering standard cover communication in rural areas, particularly as my area has full fibre broadband (paid for by the welsh Govt and the EU, NOT bloody BT/Openretch).

I'm not giving up on this, but Ofgem are a bunch of wasters who don't actually want to do their job, and refuse to speak to common members of the public (it was hard enough dealing with them at work).  This reinforces my view that the mobile phone companies should be legally prevented from installing ANY 5G infrastructure until they have finished providing a basic mobile signal to the entire UK.  If OFGEM would talk to OFCOM, and both of them would actually do the job of serving the people of the country, I might get somewhere.

The fight goes on...

Coincidence that this thread has reappeared today - there is a possibility that Mr British Gas will be installing SmartMeters for gas and electric in our house this coming Monday.

I have made it very clear that if the bloke turns up and the meters aren't SMETS2 he will be sent away, no ifs, no buts,  We'll see.

Meter reading and recording by me each month will continue .... and Mrs robgul will be introduced to the in-the-house display unit  in an effort to encourage use of light switches  ::-)

Scottish Power seem to have stopped asking me to consider a smart meter.

Perhaps having to give me another £50* has put them off.

Two cancelled appointments means they owe me £50 twice. They’ve not actually paid, of course. That would require them to know their arse from their elbow.

We had smart meters installed yesterday.  Only after I had ignored marketing emails for the last year or two, and received confirmation to a direct question confirming that SMETS 2 would be installed.

As I understand it they are paid for by a general charge on utility bills, so (as long as you have a reliable mobile signal) might as well sign up.

I've been fobbing off Scottish Power's emails for months.  Then, last week, someone actually rang me to make an appointment to fit a Smart Meter.  I told him that I didn't want one unless he could guarantee it would be SMETS2, and it would communicate with our iffy you-can-have-Vodafone-if-you-go-to-the-upstairs-front-bedroom, rural mobile signal.  He said it would.  I told him that I didn't believe him. The conversation then deteriorated somewhat and I accused him of fobbing us off with substandard, ill-thought-out technology that we as consumers have to pay for.  He then hung up on me. 

I win.  Again.....

In Scotland and the northern parts of England, they use a separate radio network. So doesn't need a mobile phone signal. Maybe better coverage.

Apparently they can also work in a mesh mode. ie it relays the signal through your neighbours meter, until it gets to one with a network connection. So it could improve, as more people get them installed.

That sounds promising, but it relies on a) having neighbours with smart meters (presumably on the same suppliers?)
 and b) having neighbours at all...

I wonder what the range of them is, between meshed meters.


We have a next door neighbour one side (which is about 30 metres away, and they are not with the same supplier).  I imagine they have resisted a smart meter because a) they are Jehovah's witnesses, and b) they are convinced wifi fries their grandchildrens brains. Apart from these oddities, they are perfect decent folk, and share vegetables, and take in parcels, etc.

Other than that, the nearest neighbour is about 400 metres away, and the next one, about twice that in the other direction.

Tens of metres for Zigbee.

According to this page https://www.smartme.co.uk/technical.html (https://www.smartme.co.uk/technical.html) (I make no claims for its authenticity and know very little about this stuff) Zigbee is for communication within a property:
Quote
The Home Area network or HAN is a bit like your home broadband wireless network and will be used to communicate between the meters, the In Home Display (previously known as Smart Meter Display or Home Energy Monitor) and other items as and when they become available. However where the meter is a long way from the location of the In Home Display, or thick walls are in the way, the current technology (Zigbee at 2.4GHz) won't work. This could be the case for up to 30% of properties.

A different communications method (Zigbee 868MHz) will improve this for about 3.5% of properties but that still leave a large number for whom Smart Meters won't work. Zigbee 868MHz should be available some time in 2018.
Meshing is for comms between your house and (eventually) the Power company.

Quote
The Wide Area Network or WAN is the name given to the communications network between the meters and the company responsible for collecting the data and passing it on to other businesses such as suppliers. This company will usually be the DCC (Data Communications Company) which the government has set up especially for this role supporting the final SMETS2 meters. Depending on the Communications Service Provider, which varies by areas of the UK, the technology can change depending on what works best in a local area. Sometimes your meter will communicate directly with DCC and sometimes it will talk through the meters around you to reach a particular meter which has direct communications with DCC. This form of communications looks like a mesh when you draw out the possible links between meters and is therefore known as a Mesh network.

Man got the OK to do both meters - did all the checks, pulled the main fuse and took the cover off the existing electric meter - to find that one of the screws holding the incoming cable in the clamp had sheared across the screwdriver slot so that it couldn't be undone . . . he reckoned it was over-torqued when the meter was replaced about 10 years ago. 

Of course, the task of sorting it wasn't in his remit so he had to report a fault for Western Power to come out and release the incoming terminal block (on the live side) to be able to get the meter off and fit a new (old style) meter before British Gas comes back to fit the SmartMeter.  Oh joy.

We've just requested to switch to EDF's EV tariff. This requires that you have an EV, and is either 12.5p/unit if you don't have a smart meter, or 8p for 10h overnight (9pm->7am), and ~19p at other times, plus 8p from Friday 9pm right through until Monday 7am. All washing etc at the weekend then?

We have a smart meter. Last year I tried to switch us over to the dual rate tariff, but was told no, as our meter was SMETS1 and they would not replace it. So we spoke to British Gas, who also have an EV tariff but with a higher night rate; they were the original supplier when we got the smart meter. I assumed they'd be able to use it. Nope... insane. But they said they would install a new smart meter. This seems to be SMETS2 from what I can tell (looking up model and variant online).

EDF recently emailed to say we could have the 12.5p flat rate - this didn't exist back when we first spoke to them - as a lot of people complained about not being able to have an EV tariff. We decided to try again, thinking that we'd get the split rate. No, they still think our meter is SMETS1. They will us switch to the split rate when our meter is upgraded to SMETS2 in the future.

I am not sure if EDF's info is out of date, or if the meter is really SMETS1 despite my online research suggesting it's SMETS2. I'm hoping this is their error as the split rate will save us money (even so, a flat 12.5p/unit is already going to save us money as it's almost as low as our current night rate).

To update my experience - after a couple "not my job guv" visits a British Gas guy came and broke away the plastic cup around the sheared screw, used my pump pliers to release and fitted noth electric and gas meters (SMETS 2) - that was in mid-December . . . . . we're now moving house at the end of this week and the new house has old-style meters .... and the incumbent supplier (AVRO0 doesn't do smart meters at the moment . . . . that said a quick calculate suggests that the costs are quite a bit lower than we're paying now so I'll just read the meters and email them . . . . unless I get a better deal from British Gas as we're deserting them.

All good fun  . . . . but don't get me started on getting BT to move our phone line and broadband to the new place . . .  it's just 1.46km away (and nearer to the phone exchange - which is actually on the top floor of a Premier Inn in the centre of town) - they need the existing BT user at the new house to cease the line before we can order the change . . . . that then takes 3 days (and that's fastracked as it's a business broadband deal)   Aaaaargh!

Ecotricity phoned me a couple of days ago to offer a smart meter. They are booked in to install it/them next Friday.

When we signed up with Ecotricity 6 years ago they didn’t offer a smart meter, even though SSE, who previously supplied us, did.

EDF recently emailed to say we could have the 12.5p flat rate - this didn't exist back when we first spoke to them - as a lot of people complained about not being able to have an EV tariff. We decided to try again, thinking that we'd get the split rate. No, they still think our meter is SMETS1. They will us switch to the split rate when our meter is upgraded to SMETS2 in the future.

I am not sure if EDF's info is out of date, or if the meter is really SMETS1 despite my online research suggesting it's SMETS2. I'm hoping this is their error as the split rate will save us money (even so, a flat 12.5p/unit is already going to save us money as it's almost as low as our current night rate).

So our switch seems to have happened and yes the smart meter is sending data to EDF despite their claim it was not compatible. We seem to be on the 12.5p flat rate.  This should change to the 8p at night rate once everything is up and running. For now I’m trying to charge the car on sunny days as there’s no penalty when the sun goes in. With the split rate I’ll have to be more careful as you can end up spending more if not careful.

What a palaver. Should never have needed to change the meter to be able to switch tariff.

Have you seen the Octopus EV tariff at 5p a unit off-peak?

Yes, a colleague mentioned it some time back. I think we will benefit more from the EDF rate (it's 9pm-7am weeknights and 9pm Friday until 7am Monday over the whole weekend). There is probably not much in it but the number of hours of cheap rate on EDF probably swing it in their favour for our usage, and particularly because we will avoid peak rate use for much of the time with the solar panels.

We have decided to stick with Ecotricity. I have read good things about Dale Vince helping XR and promising funds when the government gets taken to court by environmentalists.

A little bit of background...

First, if you think Ofgen, and Ofcom, and all the other Ofs, are there to protect the interest of consumers of vital amenities, please ask yourself the question: Who regulates the regulators? Answer, the Government. So please give them a bit of slack - they spend most of their time rushing to implement one headline-grabbing half-baked scheme after another...

I'd don't know the current state of play, but here is how things were set up approx 10 years ago (when smart metres were first introduced)... Ofgem forces the big six energy companies (and only them, cause that is only fair!) to add an extra ~5% on all their bills (ie. on all your bills) and said "We are going to give this money back IF you install energy saving equipment/materials into peoples' homes."

Of course that allows the Government to go "Look at all the amazing things we are doing to save the environment!" without having to spend any of their money, or explaining that actually the money is coming directly from consumers...

But it is totally crazee... I mean energy saving is not the core competence of the energy companies, not something close to their hearts, not really in their best interests! Still money is money, so they get some contractors to stick a smart meter on your wall (who cares if it works!), or throw some insulation in your loft - low lying fruit!

So I hope that helps to explain the mess... Yes, there are technical problems, but after 10 years those could have been sorted out had there been some management. Instead responsibility is shared between Government always looking for a quick-fix with no long term commitment, large companies who want to make a profit (not unreasonably IMO), and in between is some not-for-profit organisation which was set up to collect and distribute all the data coming from the smart meters - I've never heard of them but I reckon they don't stand much of a chance!!

In conclusion - smart meters are good in theory, it is the implementation which has been poor.

Should you get one? It won't hurt you, but it might not benefit you either!

Would be nice if you added a bit of detail.

Are you referring to :-

Renewables Obligation
Warm Home Discount
Energy Company Obligation
Smart Meter Levies
Feed in Tariff Levy (probably not)

These are all levied on all suppliers not just the big 6 (incidentally an outdated term since Ovo bought the SSE supply wing).   Agreed WHD only kicks in above 250k supply points.  Bulb, Octopus and Ovo are all over 1m customers. 

I’m not quite sure who the data collecting body that you’ve never heard of are - Elexon ?

I agree that simply installing a smart meter doesn’t reduce consumption.  You have to take the data and then make informed decisions.  This is where the adverts are wrong.  Suppliers need to roll the meters out as required but then really use what they do to offer cleverer tariffs and improve their balancing.   I also agree that Ofgem just run around trying to fill holes rather than setting strategies.

It is a huge piece of misinformation that suppliers make a tonne of money.  Bulb lost £130m last year and Octopus £30m.  SSE sold their supply book and npower have been trying to sell theirs for 2 years.  Centrica’s share price is a fraction of what it used to be.  Ecotricity are loss making and I question their authenticity.  15 suppliers have gone out of business in the last year.  The 2 councils that entered the energy supply sector have done a really poor job.

Probably just as well I didn't!

I left this all behind years ago...

but at that time the BIG ONE was called 'Green Deal'...
Now that I look at their Web site I see all kinds of:

 > insulation
 > heating
 > draught-proofing
 > double glazing
 > renewable energy generation

but not Smart Meters!

Actually, it sort of makes sense for them to be part of a separate scheme - the supply companies are a bit sensitive about people fiddling with their meters. (It is not a difficult job, and they will let subcontractors do it after a bit of vetting and training...)

And things have obviously changed slightly...

However, the point I was trying to make is that the 'solution' depends on several players, who were playing different games, which is why I am not surprised the roll-out has taken much longer than expected. (Nor am I surprised you can list 4~5 schemes which might apply, might overlap, might...)

To put it another way - the problem of getting one 'box' to talk to another 'box' is much compounded when those boxes are sitting in different systems in different organisations, whose goals and objectives don't align terribly well (and mostly competitors who are not in the habit of collaborating with each other).

I'm sure you have more accurate and up-to-date information than me, but you are right... there are a lot of things the public are not aware of...

For starters - the meter and the isolation switch/fuse are the only parts of the system the 'supply' companies have responsibility for, the wires into your house belong to you, the wires into the meter belong to the 'distribution' companies - who are strictly kept separate to the supply companies.

The supply companies, ie. those companies which we as customers interact with (if you can call it that!) are simply billing companies - they need to track how much electricity you consume and bill you accordingly. That is all. Simple (you would think!).

Some people may not like the big supermarkets, like Tesco and Sainburys, but in terms of getting food from their suppliers and onto their shelves, they are incredibly efficient. In a similar way, the supply companies are also incredibly efficient - with millions of customers they cannot afford to screw it up. (They have done in the past when updating their systems, and it was not pretty!)

To be efficient they need efficient systems - ones which are not very flexible... (But equally you won't get far asking a supermarket for a pint of milk instead of a litre... if you see what I mean.)

The total number of supply companies around show the 'barriers to entry' have been removed. As many are going out of business, that shows the market is efficient. It also shows, as you say, there is not a lot of easy profits around in the business.

Yes, Centrica share price has declined from over 400p in 2012 to under 40p today - that would destroy most companies, yet they are largely the same company doing the same thing! It is their perceived ability to make profits in the future which has declined.

Consumers have complained - that has been picked up by the press who have kicked the government into doing something, they have kicked Ofgen who have kicked the supply companies.

What is not obvious is the amount of red tape involved - the companies have very little freedom of movement. For eg. if you compare the bills from two different companies I'll guarantee they are very similar in layout and format, often using identical words or phrases - that is because it is nearly all mandated by Ofgen. (Whether or not you find the information useful I'll leave to you to decide.)


Regarding the smart meters themselves - they have a memory sufficiently large to hold several days of readings, which they squirt out at night as a data stream when the network is idle anyway - so it does not cost much. (And seems there are other options now.)
 
But to work, there must be an agreement with a network carrier and bulk purchase SIM cards, so the installer is unlikely to have a selection of networks s/he can try out for signal strength at the time of installation.

For the internal comms, I am not sure zigbee would be chosen again if starting today, but obviously there is a certain amount of momentum given the 16 million systems already installed.
 
To be fair - all those low power rf systems have strengths and weaknesses. It is not just operating distances (and remember there can be big differences between optimum and non-optimum conditions), but also security, AND interference - in the 2.4 GHz band also sits wi-fi, bluetooth and your microwave oven for eg!

You are also totally right - the smart meters are part of a bigger picture - for suppliers to "offer cleverer tariffs and improve their balancing." That is because smart meters are more of less constantly monitoring the supply (please don't quote me, but it is something like each one minute reading is an average over that time span - which is very different from monthly (give or take!) readings!)

That is hugely important because the ability to charge different tariffs at different times of the day is a way of lowering peak demand by shifting when people charge their electric cars, for example.

The alternative is upgrading the electric supply network to meet the perceived rise in demand, which is mega expensive.

It is an industry wide problem, which no one wants to tackle, least of all the suppliers who, as you point out are already well screwed and don't have the resources to even think about it.

 A lot of people will be happy to see the supply companies killed off, but that is not a solution. And a lot of people don't realise that a company need to make a profit in order to breathe - to make improvements. And very few people realise an efficient electricity supply is a core part of the low-carbon, green future they all want.

Apologies for waffling on and on!

And 2 suppliers go bust in the last 2 days.

Without wanting to go all COVID-19 in another thread, what are seeing at the moment is industrial demand coming down but domestic demand coming up as people wfh. Half hourly metering is already in place in business so suppliers see the change in consumption and can adjust for it.  Because a lot of domestic meters are still quarterly read the supplier will not be a able to adjust their forecasts quickly enough.  Smart metering would offer daily consumption profiling allowing the supplier to react more quickly.

We had an appointment for smart meter installation a month or so ago. The chap turned up at the allotted hour, took one look at the location of our current meter and stated there was no way he could get a new meter in there. He then left.

We now have a smart meter.

And in the first 4 hours of it's use, pulled over 700kw, constantly... on a supply that can do max 16kw... I am now searching the flat to find which usb wall wart is going white hot and starting to produce plasma...
