I’ve got onto customer service and they have advised they will raise it with the Drive Smart Team.
I attached the usage data for the month of February as well as the data for the month of March prior to the transfer to the new tariff, just to provide the evidence it seems high for the remainder of the month.
I’ll keep you posted. It’s as if the Smart Meter, Next Connect App and Tariff aren’t talking to each other.
Must be difficult to extract how much kWh have been used in a set period? How much was for the car? How much was the house using at that same time possibly?
Teething problems that I hope will be rectified easily.
This is why it would be good for the Next Connect App to show data for the previous charges as you could easily prove how much kWh were used at certain times of days and cross reference that with the end of month bill.

Afternoon,

So had a reply that the EV team are confirming my usage data was correct. I asked if they could confirm that the usage corresponded to the times of the Next Connect App charging periods. The response was your off peak usage is billed from your off peak times from 00:00-07:00.

I then stated that my Tariff charges off peak prices irrespective of the time of day if the usage is to charge my EV vehicle. Again I provided my data to prove that the high usage was at times when my Zappi was charging my Tesla vehicle. This was on the 22nd and 31st March.

I’ve now been through the telephone helpline and a complaint form has been sent to the EV team from the customer service representative.

I’ve attached my data and charges just for your information.

Just to confirm I’m not disputing the amount of energy used during the peak times, it’s that the usage should have been billed at the cheap off peak rate, instead it’s been billed at the higher peak rate, even though this usage was for the charging of the supported Tesla EV utilising the Eon Next Connect App.

Good job pursuing this, and hopefully they'll get to the bottom of it.

I suppose it's fortunate that your normal peak usage is so low (battery system?). I guess many people have higher peak usage so this sort of mistake wouldn't be so obvious.

Also, you might get to see whether the whole house load gets put on the off-peak rate during charge periods (I can't see how it can't - they can legally only use the meter for billing, so no way of separating consumption).

Anyway, good luck!

Thanks. Yes unsure how they can differentiate between electricity for the car and electricity for the house load between those 30 minute periods…unless the Tesla communicates back to the Next Connect App the total amount of electricity added into the vehicle then a calculation of Total Load - EV load.

This is why the app needs extra data functionality added, so you can see previous charging data, previous schedules etc. It’s only due to being able to access data in my other Inverter and Zappi app I can prove it’s EV charging at those times that accounts for the higher peak time usage. It’s just been incorrectly billed.

.

Agreed - My initial guess was somehow the car would communicate back how much it had used, so the billing could work out how much of the cheap rate to bill for the car and allocate the day rate for the remainder of the household usage.

However I don't think that it's that clever - looking at discussions on various forums with people using tentacled smart charging... the opinion seems to be that whilst your cheap-rate charging kicks in during the daytime you will actually be getting bonus cheap rate leccy for the rest of the house too 😀

I’d be quite content with that outcome. Unfortunately I’ve got the worst possible outcome at the moment, come and be a trialist, and the first billing period everything peak time is being billed at the peak rate irrespective of what it is for.

If the trial wasn’t ready then don’t launch, or ensure that there is a dedicated support team for this particular tariff to be able to report directly to.

Until it’s resolved there’s no incentive to continue to use the Next Connect App as I don’t want to be charged incorrectly. So probably have to go back to 00:00-07:00 to ensure I’m billed correctly.

I hope it is resolved though, as again the ability to charge in the day time creates more opportunities to benefit from cheap periods of electricity.

@Wills170 - though wasn't there a £120 incentive to sign up for this tariff as beta testers?

[Wills170]

That’s correct, there was a £10 credit per calendar month for being part of the trial. I didn’t assume though that this was to compensate for incorrect billing 😂
