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!

Intelligent Octopus Go - limited beta

MrMessy Yeah IOG seems off, we'll get this sorted.

Looks like this is only for the default IOG slot, not ad-hoc charge slots, would you agree @MrMessy ?

Fix being rolled out now.

MrMessy

admin I would imagine IOG was impacted because the "standard" cheap periods crosses midnight. I don't think any other tariffs do that

Don't know about the ad-hoc charging, as I didn't charge at all over the weekend but, I suspect they would behave in a similar way to Agile.

Thanks for sorting. I'll be watching like a hawk tonight.😁

I just logged in to report the same thing but @MrMessy was obviously on the ball! I hadn't checked for a couple of nights but noticed the same issue had happened for me for the last two nights. Glad it's getting sorted.👍

MrMessy

SOH failure incoming...

J1m

Just checked and mine stopped charging at 04:30 as well this morning, although the IO schedule did say 23:30 - 05:30

admin

J1m Check inverter log and time as well please.

I’ll be off for next few days but will look into urgent issues.

RobinG

Can I join the beta please

admin

J1m thanks for that, will check this out later today. Looks like end time disable for IOG is still off.

MrMessy

Given the current hiccup, this could be interesting...😬

admin

MrMessy Right, another issue with IOG slots sorted in now deployed version. Let us know if you see any weird end of IOG default slot problems still, thank you!

MrMessy

admin Well, that seemed to go according to plan. I had paused my "IOG Fix" schedule, to see the effect, but I'll put it back tonight until we've confirmed the 04:30 issue is fixed.
WW clearly reacting to some overnight changes from Octopus that I didn't see ...

... and no unexpected stopping at 04:30 ...

I still haven't figured out what happens to Kraken at 05:56 though. I've seen more FB posts with schedules changing at the same point, but not sufficient to identify any correlation yet. There's the usual do-gooders saying that's just how IOG works, and I'm fine with Octopus adjusting schedules on the fly, but there must be some significance to that exact time and it's bugging me.

Anyway, rambling a bit now. Keep up the good work.

P.S. Nearly forgot ...
It's only a very minor niggle but, the last change from Octopus put the end time at 06:14, as did WW. However, it would still be cheap rate until 06:30. Is it possible to forward set the time to suit?

@admin is this doable?

admin

MrMessy Is this true? Does IOG cheap rate apply for the remaining half hour 00/30 mins on the hour?

I'd like to avoid users complaining we don't stop in time and they feel they get charged beyond the cheap IOG mapped slots' end time.

MrMessy

admin if Octopus schedule even 1 minute of charging in any given 1/2hr slot, then the whole 1/2hr is at the IOG 7p rate.
Perhaps @J1m @JayC and others could confirm?

admin

MrMessy Could well be simply due to their typical half hourly pricing slots. Likely related to how Kraken deals with dynamic pricing.

Should be easy enough for us to round up the end time to the nearest next 00/30 min on the hour.

JayC

MrMessy even 1 minute of charging in any given 1/2hr slot, then the whole 1/2hr is at the IOG 7p rate.

Agree although unable to find documentation to support.
Example: 17:54 slot start = 7p from 17:30.

I've had a problem today which I've just noticed. My batteries have been charged from 80% to 100% this afternoon (at peak rate!!).
I had my Giv inverter upgraded to a Gen3 yesterday and paused all my WW schedules yesterday and overnight as the batteries were recalibrated, finished recharging around 4a.m. this morning. I re-enabled my WW schedules this morning and checked the IOG schedule, which had just the 23:30 to 04:30 charging schedule set for tonight. After noticing this afternoon's unexpected charging I checked the IOG schedule and it had set up the charge this afternoon! IOG schedule and activity log below!

Edit: Should have done this in the first place and just checked on the Octopus app and there are three schedules set for today! Strange though, as my EV was charged to 100% by 1a.m last night but I haven't unplugged it, yet I've had a cheap rate house battery charge!! Apologies Admin!

admin

J1m Right, so all looks good yeah?

KristianS

J1m This can always be manipulated by setting your Charge to value to a value less than the current battery value for the EV. Which is exactly what I have done to stop charging while we are on this horrendous lul of Wind and Solar just now. Only 4% renewables on the grid at the moment and if you are Agile - current 30 min is at 85p kWh - Ouch

J1m

KristianS Well I'd set the EV to do a top up charge from around 80% to 100%, as the home batteries were recalibrating, and started to charge from the grid at around 8:30p.m last night. Obviously by doing this the batteries charged at cheap rate as Octopus immediately scheduled a charge. The EV finished charging at 100% not long after midnight. I'd forgotten to unplug the car, and even though the car was fully charged these 3 schedules appeared today which gave me a cheap rate boost. I still don't understand why but I'm not complaining now 😃
