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

admin Success!!!
Octopus schedule:
23:00-23:30
23:30-00:00
00:00-06:00

I know it looks like the battery discharged in to the EV a bit near the end but, I haven't taken the Giv batteries over 85% for a while and set 90% last night which it overshot a bit. I think this is down to an SoC jump near the end of the battery charging.

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

admin

extraneous-pattern Excellent, great to hear it, thanks for reporting back!

@admin please would you add me [ quarterly-position ] to the beta (full use case sent by email).
IOG and Giv AIO
Thank you (and for the amazing work you have done so far - can't recomend the simplicity of the UX highly enough. No yaml for me.)

admin

JayC All sorted for you - you can access Intelligent Octopus settings from the menu.

Thank you for adding me. Interesting choice of initial settings. Definitely a solid MVP.
On the Hold option I'd like to see an expansion to:
Hold (no charging nor discharging)
Charge Only (so whenever IOG charge the EV they are also charging the battery BUT the battery is not discharging to service any load. The load being fed by the 7p IOG rate)
Discharge Auto Resume (a sub option of Charge Only. Facilitating the return to WW schedule post IOG event).

Ardvarky

Hi Admin,
Please could you add me the IOG BETA.

WattID: cautious-power

Many thanks

admin

JayC Charge Only (so whenever IOG charge the EV they are also charging the battery BUT the battery is not discharging to service any load. The load being fed by the 7p IOG rate)

This already happens, unless I am misunderstanding you.

When you untick 'Hold charge', your battery will be charged to the level you set and kept that way, no discharge will happen when your battery is charging, so house load will be met by the 7p IOG grid rate.

At the end of the charge IOG slot, normal service resumes and your battery will be used to feed house load.

If this this not what you are experiencing, could you please detail your findings? Thanks!

JayC

Hi,
@admin Would you please clarify.
You say “if i want my battery to charge toggle to off”.
The text adjacent to the button reads “When the battery is on hold, it will not charge or discharge. Leave the 'Hold charge' toggle OFF if you want to charge you battery.”
My issue (and I believe a common one) is that if i do not Hold the battery it will discharge into the EV.

My ask is that for a version of Hold (Dis-Hold?) that prevents battery discharge yet allows charge during an IOG event.

admin

JayC that is exactly what happens when you toggle hold to off. Instead of Hold, it will charge your battery during any IOG slot.

So neither Hold toggle On or Off will result in your battery discharging into your EV during an IOG slot.

Have you used and activated the IOG integration yet? I would be surprised if it doesn’t do what you want already.

Ardvarky

moved onto IOG - can I be added to this beta please?

Ardvarky Done!

Hello all,

I have just been granted access to IOG via Wonderwatt.

Plugged my car in and received my mapping.

But on Wonderwatt, the mapping shows as the standard time range.

How long does it take for Wonderwatt to update?

Many thanks!

admin

Ardvarky It would do, because the mapped slots fall inside your standard 23:30-5:30 default IOG off peak price window.

You get full off peak price during that window. So Octopus is being cheeky and only giving you a few mapped slots & controlling it. In theory you could charge your car every night between 23:30-5:30 on IOG.

It only takes a minute or two for us to pick up your mapped slots, but we consolidate them, especially if they fall within the default IOG window.

Ardvarky

admin ok thanks for explaining! It’s all new to me so might take a few days to suss it all out.

admin Hello,

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

Cheers,

Warren.

admin

Woz86 All done for you, you should have access to the Intelligent Octopus section now via the menu.

WW ID spiffy-point

I have occasionally seen that my battery is charging outside the 2330-0530 even when my car isn't actively charging. Seems like extra slots are being picked up.

I assume that these are valid extra slots allocated by Octopus and I will be charged at the off peak rate?

For example today I have a slot if 1100-1200 so my battery is charging.

Woz86

Good morning,

Everything is going great so far. I have noticed a couple of things. Last night a charge event was triggered between 22:30 and 05:30 from the IOG section, this was correct as octopus gave me the hr before normal cheap rate. But looking at my givenergy settings the timed charge is still enabled for 22:30 - 05:30. Will WW pick this up and change the times back before this evening?

The second unrelated thing I have noticed is that I had auto charge rate enabled for the overnight charge a few days ago. But the next day this reduced charge rate was still set when the battery was charging from the solar. Is this normal?

Anyway, thank you for having me onboard.

MrMessy

Woz86
If you check this page, it will tell you the next planned charge.
The default is IOG core cheap rate:
https://app.wonderwatt.com/intelli-octo

AFAIK the charge rate remains the same until the next charge session, when it's set again.
You can switch off adaptive rate and set to 100% if you like.

BTW you're generally better off financially charging batteries overnight at 7p and exporting all your solar at 15p, assuming you're not on FiT.
I use the "pause charge" in the Giv portal to do this, but it's not available on gen1 inverters.

PeteC

Woz86 The reduced charge during the day, after charging overnight shouldn't be happening. It never used to, but since upgrading my GivEnergy All-In-One firmware recently I've noticed this occurring too. It's very annoying as we're losing spare solar which could be going into the battery. I'm having to reset to maximum charge power in the app - although oddly enough, not today.
Also, the battery reserve keeps resetting to 4%.
I'm not sure if these issues are caused by Wonder Watt, or it's really a GivEnergy issue. Considering I only noticed it after the firmware update, I suspect a GivEnergy problem.

Woz86

MrMessy understood. But the issue as I see it is yesterday’s timed import from 22:30 is still active in the inverter settings. Tonight the iog import times are from 23:00. Therefore it looks like without my intervention, my battery will charge up for half an hour on the daytime rate. I was wondering if after the standard iog import finishes at 05:30 could the inverter import times be disabled until the next set of commands sets the times.
