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 😂

Morning, so just a little update on the ongoing issue. Had a response yesterday that there was no EV connected to my account to take advantage of the off peak charging.
After providing imagery of the Next Connect App in operation charging with scheduled times, Next Connect App correctly showing my Tesla, and Tesla API showing E.On Next gaining access to my vehicle on the 21st March, after further investigations delving even deeper the car is apparently connected to my Solar Account.

So I have one account for my gas and electric, and when I installed the solar I also went with E.On for my Smart Export Guarantee (SEG), which gave me another account number.

Now I only have one log in for E.On Next, and I can see both accounts in my dashboard, and I’m showing as logged into my Gas/Electric account on my dashboard.

I didn’t remember on the initial setup of the Next Connect App ever been asked to choose which account I wanted the car to be attached to, and so the advice from the EV team was to delink the Tesla and go through the setup process again and choose the correct account to link the car.

So again, I logged in using my only login, went through the setup process again, taking screen shots of each step of the 5 step process, slowly going through the process making sure I haven’t missed anything, and at no point is there any option of selecting which account I want the EV to be attached to. The EV has again connected, done a test charge and is waiting to go.

But I have no idea if the EV has again been connected to the “Solar” account, or to the Gas/Electric account. I replied back last evening to the customer service rep, along with the screenshots of the setup process; and am now awaiting a reply as to whether it’s connected correctly.

I can’t tell if I’m completely useless 😂 or whether this trial is throwing up the necessary issues to be resolved prior to it being rolled out. I do know one thing, having a dedicated telephone number for the EV team would be really helpful.

The WhatsApp chat team didn’t know what was happening and advised to email, and the telephone call handler who submitted a form on my behalf last week has never got back to me. Going via email, and working at the same time, I’m managing one email a day each way and it’s taking a long time to solve what appears a very simple issue. For instance, why can’t the IT system just transfer the car to the other account if that’s the issue?
