EDF Smart Meter not recording separate day/night for Economy 7

    Hi - it probably is just a question of the meter needing to connect up and download it's configuration from EDF, which could take a couple of weeks but is likely to happen in a day or so. In the meantime, you're benefitting from extra off-peak hours so there's not much to lose by waiting. As far as the wiring is concerned, there isn't much scope for doing it wrong as long as the 5th wire is either providing power directly to your storage/immersion heaters or switching a contactor. But if you would like to post a photo showing the inside of the meter box someone here will be able to confirm if it all looks OK. Hope this helps, Mike.
    The OP suggests the number of units is being divided equally between day and night, not that 12 hours of usage are recorded as night. If the OP usually uses most electricity at night, he/she will be paying too much. (When I lived in an E7 flat, over 80% of my annual usage was at night, although admittedly probably not at this time of year.)
    It's not entirely clear where the OP is seeing that 50% of usage goes onto each reading, but if it's the meter itself, surely this can't be corrected when it is reprogrammed in two weeks' time? Other posters seem to have assumed that the meter is working correctly, but that the readings are not being sent to EDF so that the online account is wrong, but that is not my understanding of the original post.
    Your understanding is correct and I was reading off the meter. My usage is mostly day a the moment, but with the cold weather coming up I was getting a bit worried about sorting it out as it's been 6 days since install. 

    So, since coming back from lunch and logging into my EDF account I can see they are now recognising the meter! I've just checked the meter again and I am showing a slight difference in day/night now, previously they were always exactly the same, so I am hopeful it might be sorted. I have had to update to 30 min readings so can't see what they are receiving in the Energy Hub thing yet.

    I am going to monitor it morning/evening to double check what is being applied to each rate and will post any updates here, but the whole process has been confusing with little information from the supplier. They make it seem as if everything will be plug and play.

    Perhaps the OP is referring to his portable IHD instead of the meter on the wall?
    It was off the meter, the installer could not pair the IHD so would not give me one. I have had to request one from customer service.

    Exactly, if the usage has already been recorded on the meter, how can it be retrospectively be corrected?
    You are confusing metering with billing. 

    FWiW, I am with Octopus. My meter has had two registers which have been used over the past 2 1/2 years. I am now on a two period/two rate tariff but only one register is used for recording usage. Octopus bills using 30 minute usage data. As EDF has bought into the Kraken system, then EDF may be moving to this for its new smart meter accounts. 
  • My new meter being installed tomorrow (after 2 failed attempts).

    I am relying on the latest email invitation from EDF to make sure they get it right!

    "Industry changes may impact your
    meter
    Your current electricity meter uses the Radio TeleSwitch Service (RTS), which relies
    on radio signals to switch your meter between on and off-peak hours. RTS is an
    industry run service which is coming to an end^.
    Once this service is shut down, your meter could lose functionality and off-peak
    timings could change. This could also result in the loss of important functions like
    heating and hot water.
    You could also see increased costs, as when the RTS service ends your off-peak
    hours may no longer be picked up. By upgrading your meter, you can continue to
    benefit from your off-peak hours without the need for the radio signal.
    Book an appointment"

    So far as I am concerned it's now up to EDF to get it right and I would hope that this will apply to all customers who are on the E7 tariff.

    If you have storage heaters on a separate circuit do not let the installer proceed until they confirm they are installing an E7 5 port meter. These are people installing on behalf of EDF so I wouldn't just take EDF's word for it..

    Or a four-port meter with an ALCS-controlled external contactor. Just as effective, not quite as tidy.

    The Morrisons Data Services installer told me they almost always install 5 port now for E7.
  • So, it's not actually sending data off yet, so I am taking manual reads for a few days as I am still not convinced. 

    I noticed my neighbours flat has 5 fat wires to/from his meter whereas mine looks like the below pic. I'd be grateful if anyone can double check this looks okay.

    Does the thinner of the five wires attached to the new meter lead to a separate unit with thicker wires attached to that? It look like you might have an external contactor as suggested by QrizB.

    The thinner wire from the new meter should be energised during the off peak period and that should then control a relay handling higher current switching for the off peak circuits.

    Alternatively, depending on the current rating of the off peak circuit, the thinner wire might go straight to a separate consumer unit (fuse box in old speak) to supply the off peak circuits. 

    It is hard to say without seeing more of the layout.

    Either way, it does look as though the meter has been wired for Economy 7.

    After a few days now, are you noticing different readings on the meter for day and night rates?

    If you scroll through the meter display does it come up with a message similar to "Active tariff rate" with a £ value?
    Our smart meter is different, but it shows the active tariff rate and this changes value when the meter switches from peak to off peak rates and vice versa. When scrolling between the Rate 1 and Rate 2 displays, it also has an arrow which points at either the Rate 1 or Rate 2 text to indicate which rate is currently being recorded.

    It's a five port meter.
    I think the grey cables are all original, with only the blue ones being new for this installation.
    There are two thick greys - live numbered 4 at the meter, and neutral from the white terminal block - that vanish off the top of the photo and which I expect feed your main consumer unit.
    There are also two thinner greys - live numbered 5 at the meter, neutral from the white terminal block - that go off to the left. These are the E7 switched feed. As lohr500 says, it would be good to see where they go.
