I had a little meter installed with the home charger
Was more around figuring out how I can go about calculating it during the switch windows. My charger thankfully has a CT clamp built in so I can see the power being delivered to the car with each charge. Unfortunately I won't be able to exclusively charge in the 5p window (use more battery than I can deliver in that window), so I have to work out the difference. I am averaging out as:

Leaf average kW being pulled is 5.45 (24.78 Kw delivered divided by 4.5Hrs charge time = 5.45kWh)
5.45kWh * 5p per kW = 27p per hour
27p * 4 hour go window = £1.09

Then I just take the difference of 21.78kW in the 4 hour go window (5.45 kWh * 4) and subtract from the total delivered to get the cost of the electricity delivered outside of the 5p window.

I'll verify tomorrow (Octopus' energy usage stats are delayed by 24 hours) how the above works out, but on my calculations above I saved ~£2.32 charging on Go lastnight compared with the standard Octopus tariff.
 
Ah it's just gone to page 5, didn't see your post
Yeah, I reread it and realised there was a strong implication of you charging outside the window (if I'd bothered to read your post properly) and altered my post, hey ho.
 
For their Go Faster and Agile tariffs, Octopus uses a generic tariff which is transmitted to the smart meter and then on to the IHD (In House Display). I am not sure what they are doing with Go for new customers. It follows that the cost calculation on the IHD is wrong. Usage is recorded just on the R1 register. Billing is done by Octopus when it receives 30 minute usage data from the DCC. SMETS2 meters (and IHDs) are not capable of coping with dynamic tariff changes. Even a simple change of tariff can take up to a week to flow through to the actual meter: this is a process undertaken by a third-party (TMA).
 
I have just seen your post about calculating the daily charge. When Go is set up, you will see in your online account a breakdown of the usage per 30 minute period. My account updated overnight to show usage data for Monday. As I have recently switched back to Agile, this data along with the cost per 30 minute period is also available in the Octopus Energy Watchdog App. Even if you are on Go, I would recommend OEW as it is a simple of way of checking whether Agile or Go would be cheaper for you.

Yeah, I'm going to look at dumping my usage to an influxdb and analyzing against Agile, and Go Faster tariffs. Unfortunately home is all electric cooking so Agile might not save as much.

Interestingly, My Octopus usage shows lower by around 1kW than what my charger stats say (without any usage in the home) . Easy one would be 29.42Kw delivered in 6 hours exact, which makes 4.90kWh average for the period - vs. Octopus portal showing 3.55kWh consumed. Not complaining too much that way around! Appreciate that my chargers CT clamp might not be exact, but if the Octopus consumption is anything to go by, I'd be concerned about my car charging at such a slow rate! My home baseline energy usage without the car charging is around 300w.
 
Had my smart meter installed (very efficiently) on 13 Feb and Go went live at midnight last night. A bit of a slow start to the process waiting for the meter to be installed but this was anticipated. Otherwise very impressed so far. We don't have gas so sounds like this will have helped.
That's good. I had mine installed on the 11th, and according to Octopus (spoke to them on the phone today) it can take 10 working days for them to start receiving meter readings. That's next Tuesday for me.

I did something similar with the data I had logged via my eMonPi. It has an dashboard that displays your usage tallied with the Agile rates.
(I reckon that little box has paid for itself easily over the couple of years I've had it. Just being able to identify what uses how much. It's surprising sometimes, and soon it will schedule my EV charging for low prices).

I used this with a few months of my house usage data last summer and came up with a figure of 9-10p average per kWh. It'll also fold in Agile Outgoing if you're going to be exporting energy to the grid.

I have a feeling (based on some comments from the person at Octopus admin and the engineer) that the delay after installation is more to do with how long it takes the engineer to send in his reports. The meter itself appeared to go through a "process" on the evening of the installation and is doing the same thing now as it was then. Again though, no gas involvement may be important.

Octopus cannot take data until the meter is properly registered with the DCC. It is a function of the layered security built into SMETS2 meters. Suppliers only have limited access to certain elements of the data.
 
A big improvement on my 5 weeks! SMETS1 or 2?
SMETS 2. Also, the Octopus engineer didn't like some of the insulation on the neutral and a crack in the fuse box so arranged for Western Power Distribution to come along and fix this while he was here. In the meantime he installed the meter. So I now have a nice new fuse box with 100 amps written on it. Prior to that the fuse rating was a "fingers crossed" guess.

And, ..... I seem to have an amazingly good mobile signal at the meter which is where I thought the whole plan was going to fall apart! The house is ancient and in the middle of nowhere, the electricity supply is only slightly less ancient so the whole exercise was a bit of a gamble but, in the end, a great result.

I think there's an aspect of that. Octopus acknowledged the install on my account dashboard at the end of the week the installation took place. I expect that was to do with them receiving the details on which metre had been installed where, etc, from the engineer.

I expect after that it's dealing with whatever company handles the communication network.
 
Back to vent a little.

Now 12-13 working days since my smart meter installation and no progress. Gave them another call (I swear they make you hold for one rendition of "Never Gonna Give You Up" as a way of trolling you), and the assistant tried to get readings, but failed to do so. She's now put me on "the list", and advised me to call back if I hadn't seen any progress in a couple of weeks. Pointed out that this delay was literally costing me money, and my patience was wearing a little.

Rather frustrating. I understand the switch is not all in their control, but more signs of progress would be great.

Also brought up that my gas meter is still listed as my old one on the account, and apparently they haven't received the technical details of that meter yet. So I expect that's going to be another dragged out story.
 
From a few installs, provided everything has been installed and commissioned correctly, I've noticed that it seems to take up to a couple of weeks for the DCC (Capita) to send the data from a new smets2 electricity meter and up to 6 weeks for a smets2 gas meter. This can even include the new serial numbers of the meters showing up on your account.

If it doesn’t happen then you may be able to get remote commissioning of your meter(s) if communication can be made between the meters and the DCC. If this doesn’t work then someone would have to be sent out to look at it.
 
Thanks for the info. I'm not that fussed about the gas meter, after all it's just a way of avoiding sending monthly readings. If that takes 6 weeks, so be it. It'll just mean my account will be debited later.

The electricity is another matter. On Agile my average unit price would have been 7.5p this week, and I'm currently paying ~15p, so I'm eager to move to it. Delays cost me money. I'm now over two weeks with the electricity meter installed, and the meter appeared on the account within a few days, so Octopus have the details. It sounds like the delay is with the DCC communication, but I get the feeling that unless I push Octopus nothing moves.

As a smart meter installer (for one of the big 6, not Octopus) - Providing the installer actually commissioned them, I can safely say the DCC (Capita) will be the ones holding it up.

It can take ages for the DCC to start releasing metering data. Hell, I’ve known it take 28 days to even get the meter serials allocated to the customer account.

Anything DCC related issues on jobs I fit have a D+31 turnaround to give them enough time to catch up.
 
SMS came to fit my smart meter this morning Monday 9 March and the mains supply cable cut-out is too old and needs Northern PowerGrid to replace. The guy said it takes 4-5 weeks and he'll report it, but I phoned NPG direct and organised a survey for next Monday. Hopefully they'll change the supply cable cut-out shortly after.
So a Heads up really to people who are starting the process, if the box on the end of your mains supply cable looks like something from the 1970's or older then it probably needs replacing, phone your grid operator immediately for advice if you don't want an even longer dragged out affair than already exists when switching to Go/Agile.
 
No progress in the last two weeks for me. Still no readings making it to Octopus. We're now 4 weeks since the installation.

Gave them a call this morning, and the Customer Agent said she'd follow up on it with the smart meter department and send me an e-mail with an update. I raised the gas meter still not being on their system, and they asked if I could send them a picture of the new meter with the serial numbers legible.

Hopefully she comes back to me, but we'll see.
