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

Hello, @admin my Growatt battery failed to charge over night. I have checked the logs and there’s no history for last night.

Is there a way to check to see why?

Many thanks

admin

Ardvarky What is your WattID please?

Odd - we can't find any entry in the logs for this. Schedules weren't paused I take it?

cautious-power

Many thanks

Ardvarky

admin Not that I'm aware off.
I set up the Planned Intelligent charge slots to charge to 100% a while back and it's been working like a dream until last night.

Below is my config:

Many thanks

admin

Ardvarky Looks good. We've added some specific additional IOG logging and deployed that to for the IOG functions so we can diagnose and understand what's happened and fix if it happens again.

Ok thanks!

Fingers crossed it's goes back to working overnight and was just a glip.

admin thank you

Have a minor niggle with WW ending smart charging sessions.
My Octopus charging session was scheduled to end at 07:00 this morning and WW picked up all the various changes through the night without issue...

My daughter unplugged her car at 06:49 this morning (before the scheduled end time and whilst still charging) and WW almost immediately ended the session, reverting back to GE battery powering the house, rather than waiting until the 5min slot before 07:00 to swap things back.

Now, it's only 10mins in this instance, but I suspect if she'd unplugged at 06:31 something similar may have happened, meaning I'd have had half an hour of battery draw when it could have still been grid draw at 7p/kWh.

Could you have a look please @admin as WW appears to be picking up the wrong end signal in this scenario? TIA

primary-hotel

admin

MrMessy Yeah, I think you raised this before, so this is all about finishing as close to the 00/30 min on the hour mark, correct?

We'll get this sorted.

MrMessy

admin yeah, that's pretty much it.
Whatever 1/2hr segment you're currently in, even by 1 minute, the cheap rate will run to the end of that, assuming you're outside of the core o/nite hrs.
eg 06:45 -> 07:00,
07:01 -> 07:30

admin

MrMessy That's deployed in a server fix now. Front end version number won't reflect this (yet).

If there's no Octo mapped slots and we have an active IOG charge running, and not in default IOG window, we only disrupt the schedule at 28/29/58/59 min marks.

MrMessy

admin will let you know how it goes in a couple of days.

MrMessy

admin unfortunately, this is still not working correctly.
I would have expected WW to set the end time to 07:00 in this scenario, rather than 06:37.......

Could you have a look please?

J1m

Just a very minor thing - and everything seems to working great, but for the last few nights the IOG charging schedule appears twice (see screenshot). Any ideas why please? neat-permission

admin

J1m Yeah we know why, we're looking further back for IOG slots as they sometimes get issued with start times up to 5 mins ago. But this is a bug at our end and we'll fix this.

admin

MrMessy It’s working for the scenario where you unplug the car, but fair point, for general IOG end times this needs to be in place too.

MrMessy

admin so you're saying that if I'd unplugged the EV between 06:30 and 06:37 (before Octopus had ended the schedule), WW would extend the charge slot to 07:00 but, because the EV was still plugged in at 06:37, the charge slot was not extended?

admin

MrMessy That's right yeah, though you may not have seen this in the activity log.

We're rolling out an update for this now though, which will round up the appropriate IOG mapped slot end time to the next 00/30 mins. So by doing this earlier in the pipeline, everything else downstream should work with these updated end times. You should only see 00 or 30 min end times for IOG going forward.

Server update to be deployed in the next 10 mins.

Thank you for enabling this function for me. All good so far - lots of extra charging slots for my home battery. I will check my bill at month-end to see if they were charged at the 7p rate! One query - I notice that, at the start of the process, an instruction is sent to set my reserve at 4% overriding my setting of 9 or 10%. Is this an essential part of the process? I normally like to keep a small reserve to ensure some systems keep running in the event of a power cut. Thanks again.

admin

tedious-intention We're effectively using the usual Giv default. We'll put something in place for this and let you know.

MrMessy

admin fab! I'll let you know in a couple of days, as per usual.😁

We'll be making use of additional smart slots this week to keep the ASHP running on the cheap.😅

MrMessy

admin apologies for the delay in responding. Wanted to make sure I'd tested this properly before coming back.

The slot end time 00/30 works perfectly. I've had numerous goes at this, unplugging just after the half hour and each time the Giv charging has ran to the expected point😀.....

...... as long as the EV is physically unplugged and we get similar to this in the Octopus app, saying unplugged:

I presume at this point the Octopus API despatches a signal and this is what WW is reacting to?

The only fly in the ointment is, when I get an early evening charge slot (IOG is so easy to manipulate, if you know how) and then a bit later reschedule to get morning slots. An ASHP chews through quite a few kWh when the temp hasn't been above 0⁰C for 3 days.🥶
In this 2nd scenario, I'm guessing there's no signal for WW to react to as the EV hasn't been physically disconnected.🤔
Anyway, as this stop/start EV charging is initiated by me, it's easy to update the times in the GE app, so no big deal.

Overall, thumbs up for this fix.👍

Off to see what other bugs I can find.🤣
