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

unwelcome-dream Happened again today. WW sent IOG charge instructions when the car was not plugged in. Can someone look at my logs and see what’s going on don’t want to be charged full whack for this.

admin

DavrosMcT You had a valid charge until 16:00, and then this was updated to a valid IOG charge to 17:00. All mapped via the IOG dispatch slots.

This is the only charge slot I have had this year on the ohme app?

admin

DavrosMcT Do you see mapped charges in your Octopus app when you plug-in? We get the smart slots from Octopus via their API.

I was under the impression that Ohme charging wasn't compatible yet, but clearly we are getting intelligent EV charge slots from the Octopus API for your account details.

MrMessy

@admin I'm currently having some car charging issues, nothing to do with WW its either an EV or charger problem but, could you post the activity log for my inverter since 8pm 6/1/25, so I can see the Octopus IOG despatch slots, as it may help me to diagnose the issue? TIA

MrMessy We have this for you, actioned at around 22:46ish:

"TimeFromOffset":"2025-01-06 22:46:00 00:00","TimeToOffset":"2025-01-07 07:30:00 00:00","KwhCharge":"-12.34"

MrMessy

admin was there anything after that?

The schedule I had from Octopus was 22:46-07:30, but the car stopped charging bang on 03:00 according to the Zappi and GE traces.
Just wondering Octopus split the schedule through the night and the car didn't restart the session.

admin

MrMessy We've noticed that issued dispatches usually tend to stay in place until after EV charging has finished. In other words, those slots are still assigned and billed at off-peak.

If not dispatched IOG slots are available, and you have an active IOG charge session going on for your inverter, we stop it at the next 00/30 min point.

MrMessy Just wondering Octopus split the schedule through the night and the car didn't restart the session.

That could definitely be the case, but we consolidate it into one condensed time slot.

I'm not having slot issues with WW or octopus. The slots are picked up within minutes every time. Neither am I having any billing issues, even when no EV charging actually happens, which is becoming more frequent.
I'm fairly certain it's a Zappi coms problem, maybe the Harvii.🤔 Think I'll give MyEnergi a shout and see if they can diagnose it.

I've set this up today first day on IOG. I have a Ohme Epod charger and the schedules appear in the Ohme app, sometimes the those schedules appear in the IOG tab in Wonder Watt but sometimes they don't, not entirely sure why like it did earlier today at 15:00 but not at 19:30. Will test to see tomorrow if I'm being billed correctly, but I'm finding the my Growatt Battery discharging to the car at certain points which I'd rather like to avoid if at all possible.

admin

ULtiMat3DruMa I'm not sure IOG is compatible with the Ohme pod in the sense that Octopus maps the adhoc slots, which you then see in the Octopus app as mapped charges.

Ultimately, that's what WW uses to work out whether Octopus has assigned cheaper charge slots for EV charging.

I'm glad to say I think you might be wrong about how Ohme sets up charging, it does appear to influence the octopus API directly and therefore you do get charge slots showing in WW (see screenshot) I think the flaky part is that sometimes when Ohme sets the charge up it just doesnt talk to octopus and thus you get billed at peak rate so if anything WW is a great way to tell if the 2 (Ohme and Octous) are talking with each other adn thus you can be reasonably sure you'll be charged for the offpeak rate when charging on peak. Thanks

admin

ULtiMat3DruMa Thanks for updating here, that's good news.
