Smart meter still on old prices (before 1st April)

Having downloaded the data for the last several days from the DCC, the rate is changing between 23:30 and 08:30 in the morning, without a gap during the night.

Therefore, my "economy 7" meter is in off peak mode (R02) 9 hours per night, instead of 7 for the old meter.

Working in my advantage, unless EDF start calculating the bills not from the R01 and R02 values of the meter, but from the readings sent itself, and correct times.

That isn't proving quite what you think it is...

The DCC don't hold any data btw, that is just data sourced from your meter and in respect of tariff information it is not definitive.

What you have there just shows how your meter tariff information is configured, it does not show which register your data is being stored in or which price your supplier is actually using for your consumption.

You can get a better idea though by using that data acquired from your meter along with two meter reading you take locally noting the two registers a day apart.

Check that the total of the readings you believe to be at the night rate match the difference in consumption recorded on the R02 register...

Yes, the DCC data is indeed sourced from my meter.

I understand the rates are not correct, but data I have displayed before exactly proves that the clock/time is also wrong: Economy 7 is supposed to provide...well, 7 hours of off peak energy per night (regardless of the actual off-peak rate).

My data is proving it's currently 9 hours, from 23:30 to 08:30, without a break/gap. The rate change is what matters here, not the actual rate used.

So my so-called "smart" meter is of course wrong on rates/cost (as it hasn't received the new tariff, despite having changed 2 weeks ago) but dumber than the previous standard meter too, when it comes to off peak hours...

Your data proves nothing of the kind.

All you've shown is that the DCC thinks you're getting 9 hours of off-peak electricity. It has no bearing on your bill.

My tariff gives me four hours of cheap electricity a night, but the DCC thinks I'm on a single-rate tariff. By bills, however, are correct and I suspect yours are too.

I think you are just contradicting what others have said then.

You are saying your meter is sending all readings, and the energy supplier is then determining what usage belongs to peak or off-peak/what rates to apply when generating the bill? I don't think that's correct, as you would have no chance to send manual readings, if you were on economy 7.

I am just trying to clarify what determines peak or off peak? Is that the meter categorising such data (in which case, I seem to be getting 9 hours per night), or the electricity company deciding that all readings received during a specific time will be off peak, and charged at an off-peak rate?

I have got no idea if my bills are correct, as I haven't received one since my smart meter was installed and finally commissioned 3 months later.

I don't know exactly where you obtained your DCC data but from what you've posted you've obtained the half-hourly data. Your smart meter also reports the index readings (R01 to R04). If you are on a conventional tariff, not one like Octopus Go or Agile that explicitly uses the half-hourly data, it is the index readings that your supplier uses for billing. The half-hourly readings are a curiosity, nothing more.

Your meter has an internal clock, and settings that tell it when to energise the ALCS and your 5th terminal. Those settings also tell it when to switch between R01 and R02. Your supplier takes the R01 and R02 index readings and uses those to bill you.

I have got no idea if my bills are correct, as I haven't received one since my smart meter was installed and finally commissioned 3 months later.

I understand from previous posts that you're with EDF, who only bill their budget DD customers every six months. If you want a bill before that period is up, you can contact them via chat and request one. I've found their CS agents to be quite helpful in that respect.

At this point I would just take the small amount of time it would take to check if the registers are incrementing in line with the times the tariff is set to for day/night or if they are following the correct time pattern.

That doesn't need a bill, just two sets of meter readings 24 hours apart and the half-hour data for the same time period.

Yep, I have taken a reading for R01 and R02 from the meter tonight (can't get one from the IHD) and will check tomorrow morning if R02 (supposed to be off peak) has increased by the same amount as the sum of readings/KWh values between 23:30 and 08:30 (which seems to be my off peak window, as set on the meter).

I have used the n3rgy website (.CSV download) and the Bright/Glowmarkt API (Python script).

Neither unfortunately are reporting R01 to R04. They are only reporting KWh readings per 30 minutes, as well as cost per 30 minutes (which is wrong, given that the rates are wrong). Basically, the data below (I calculated myself the Unit Price, Cost/kWh, to see at what time of the day the meter is applying a different rate):

If it helps when aligning the data, n3rgy usually tags the half-hour data with the time the period ends.

Well, EDF has pushed the new tariff now to the meter, so at least that's resolved and IHD can show a correct cost.

However, meter hasn't transmitted any data to the DCC since yesterday, so can't do any further investigations on off peak hours at this stage.

I don't know if EDF updating the tariff made the meter stop sending data...
