We've just rolled out an initial version of Intelligent Octopus Go, enabled for a handful of users. Please DM or drop us a line at labs@wonderwatt.com with your WattID or registered Gmail email address if you would like to try this out.

Exciting. Is it just for compatible cars or chargers though, or for any car or charger?

@"Gazzagreen"#p3146 I'm in the beta if you can you have the tariff I believe it will work as its pulling from the Octopus API and controlling your inverter so has nothing to do with the car or charger. It's found my slots first time so really impressive.

Yes I’m interested please: impassioned-spirit

@"Gazzagreen"#p3146 Not related to car charger control. Mainly verifying the mapped charges for your EV and creating a hold/charge for your solar battery to match the dynamic slots, to prevent your battery draining into the EV.

@"psiloc"#p3148 Enabled for you.

I see. I'm happy on flux atm, but if I was to try this later, what I'm trying to ask is I am able to get the intelligent Go tariff from Octopus? I ask because as far as I understand it, they require a car or a charger they can control or you can't get the tariff. e.g a tesla as they can control the charging on the car, or compatible charger. Is this agreed with octopus to be able to use the WW-tariff with a non-compliant car or charger?

@"Gazzagreen"#p3151 Without a compatible EV - for which they will perform a test charge, I don't think you can get OIG. We simply check the dynamic charge slots that Octopus has assigned to your Octopus account. If you haven't got Octopus Intelligent Go, we won't retrieve any smart charge slots from Octopus when we query your account.

@"Gazzagreen"#p3151 Yep you need a car or charger that is compatible.

I might be getting a (2nd hand) Tesla later this year with Pension money :D

Hi there, impassioned-spirit First usage of IOG last night by plugging my car in and I don't think it quite went to plan! :) [URL=https://i.imgur.com/5qtopBZ.png][IMG]https://i.imgur.com/5qtopBZh.png[/IMG][/URL] So at first it picked up my smart charge of 23:30 - 06:30 and had a target of 86% at a rate of 33%, which is fine. It then, from somewhere, picked three more half hour blocks and mapped those. The problem is that in between those half hour blocks, the battery was discharged to power the house. This is not only in contradiction to the proper mapped charge but was unnecessary anyway as IOG always has off-peak rates between 23:30 and 05:30 - in fact of course the battery should still have been charging from the grid due to the dismal forecast. I don't know what happened with those additional blocks but if I check my Octopus app, those blocks are shown there right now too, so WW hasn't pulled them out of nowhere. I do know that in reality Octopus was charging my car as per the original mapped charge of 11:30 - 06:30 and this didn't get interrupted. One thing I recall, yesterday when I plugged my car in, the charge target was just 10% additional, and I _think_ it's possible that the original smart charge schedule was these three blocks. I subsequently changed the charge target to be 60% additional, and it mapped the new proper schedule. I wonder if both sets of instructions were still in the API? Is there something you need to be checking to know whether you have the latest schedule? In any case would it be possible to configure WW so that it always "knows" about the basic 23:30 - 05:30 off peak, and only does something with smart charges in addition to that? Love that you're doing this by the way, please don't take any of this as a moan!

ray82 They should get deleted. Did they?

They did thanks,
Think I've got my head around how it works now 😀 will plug in tonight afterwork and see how it all goes

admin

ray82 Thanks for reporting back and confirming. 🙂

admin I think it's because that's when it's cheaper for Octopus (and presumably lower carbon intensity on the grid). Had the same problem again this morning, and yesterday, so battery very low. Hopefully it will start charging later.

admin

PeteC This should be fixed in Release 690. We now don't save individual IOG slots that get mapped and fall within the default IOG window 23:30-05:30.

I had the same problem that drained my battery again. What happened is that I plugged in the car at 02.43am when the schedule was already set. Octopus added slots all the time up to 6.30am and then from 09.30-11.00. What happened though is that the 02.43-6.30 slot got to WW but didn't work. I had it in the activity log but between 5.30 and 6.30 it didn't work and my battery charged the car. Then the 9.30-11.00 slot worked fine. It seems that the 23.30-5.30 had some priority over the 02.00-06.30

admin

angellevski Right, the issue is that the 23:30-05:30 instruction had already been sent and is set on the inverter.

We need to consider how slots that start within the default IOG window and extend are dealt with.

angellevski

admin Have you fixed this? I got it do the same thing again. This time I plugged the car in the evening before 23.30 and got slots in the night slot plus up to 6.30 in the morning and then 7.00-7.30. I got 23.30-6.30 in WW at 23.32 and then 4.30-6.30 at 4.32 but what happened is that between 5.30 and 6.30 the car was charged by the battery which drained it completely for this hour. Then 7-7.30 worked fine.

extraneous-pattern

admin great thanks. I had same issue again last night so might be worth looking. Battery was 49% this morning instead of 100%. Car charging ended within the IOG time slot which was until 0400. Battery started draining at 0400 again instead of 0530. Immersion kicked in at 0415 and drained battery.

admin

extraneous-pattern Hopefully should be addressed in Release 694.

admin yep - think you’ve cracked it! Have done a few charges since and working wonderfully, thanks

Woodentop

Could I join the IOG beta please. Thanks

admin

Woodentop No probs - dropped you a line.

Have a minor issue with last night's charging.....

Smart charging from Octopus 23:00-05:30 and 05:30-06:00

WW picked up the slots and initially set 23:00-06:00, but subsequently overwrote with 23:30-05:30
As it turns out, the EV had finished charging at 05:15 anyway, so didn't cause an issue with battery drain, but it would have, had the Octopus EV charge continued.

Could you have a look at this please?

As a sidenote, is there a reason the charge commands are not sent until after the charge period is scheduled to start?

WW-ID:primary-hotel

admin

MrMessy We'll take a look at both issues.

MrMessy

admin Just wondered if you'd had a chance to look at the underlapping charge instructions?

Does this fall under the same issue as @angellevski highlighted and, therefore, is it resolved?

Woz86

Hello,

Thank you for letting me join WW. My first EV is being delivered next month. Are you still accepting new participants and is it best to wait to join this project until I swap tariffs to IOG?

violet-local

Thank you

admin

Woz86 Yeah let us know when you're on the tariff!

Woz86

admin Hello,

I'm on the tariff now. Would you be able to add me now?

Cheers,

Warren.

admin

angellevski Thanks for the info, yeah, we have put a fix in for this, it looks like there’s still a scenario where a mapped slot can fall within an already started wider slot that should be ignored.

Looks like without the redundant 4:30 instruction, this would have worked fine, right?

angellevski

admin I guess so yes

admin

MrMessy No they’re different issues. We are adding a bunch of unit tests first to make sure the logic is correct for multiple scenarios.

The main reason we start after the slot time, is because we do need to cater for people plugging in, getting an IOG slot mapped and then WW to pick that up, which would by that time typically start in the past, despite us running that routine every minute.

We will work out a fix and hopefully get it out this week sometime.

MrMessy

OK, so back to the under/overlapping instructions.
I had a smart charging session last night 23:30-05:30, 05:30-06:30 (nope, I don't know why they spilt it as there was definitely no break according to either the GE inverter or the Zappi).
This seemed to be picked up perfectly by WW, as seen here...

... and here .......

However, instructions were then sent at 05:30 to switch charging off .......

....... leaving the battery to drain in to the EV, which was still charging until 06:30 .....

..... until I spotted it when I got up.

Does that give you any more info to go at?
