Hi All, could anyone please provide some pointers or their settings to getting the Intelligent Go scheduling for EV charge working ? Octopus app comes up with the schedule when i plug in if the charger is set to plug and charge - great, but what should the charger be set to ? Schedule for 24x7 or Activate plug and charge etc… just a copy of all the settings someone is using who has this working will be great. (Octopus is all correctly connected to the Tesla)
Had this working great with my old Ohme charger, but the givenergy is just not playing ball… cant wait for the new firmware with local inverter communications !!
You will need to check if your car and charger combination are supported by Octopus Intelligent Go. They have a checker on the web site. It’s why I went with Ohme.
Here’s what works for me (Tariff Intell Oct Go, Zappi charger, Volvo EX30): I turn off Octopus’s smart charging, and use the car’s charging settings to only charge 23:30-05:30 in the cheap 7p/kWh period. The Zappi charger is set to boost to give max charge. The car is set to limit the current to 32 Amps = 7.36kW @ 230V. Works a dream every time.
Why would you do that? The Zappi is compatible and so you just let Octopus to calculate the charge period.
Octopus will start and stop the charge according to the schedule it sets via the Zappi.
It can benefit you by getting a charge slot outside/longer than the 6 hours (if you get a charge slot outside of the 6 hours, you get that and the 6hrs at the cheap rate).
If you don’t use the smart charging schedule process for too long you could be kicked off the tariff. Setting your charger to charge during the cheap rate isn’t that.
You’re not taking advantage of the benefits and purpose of IOG.
All you need to do is have the Zappi setup with no charging schedules and just to charge as soon as you plug in, once the car is plugged in and charging either Octopus will stop the charge and then start it later on at the point it’s calculated the schedule to start or you can pause the charging yourself shortly after plugging in and Octopus will still calculate the schedule and start the charge when it needs too.
If Octopus is setting a schedule, thats it, you’re done. Its working as it should. The car is communicating with Octopus.
Just have it set up as plug and go, no schedules needed, it tells you this in the Octopus FAQs because it’s applicable for any charger you use with IOG. It’s very important you DON’T have schedules in place via the car or charger as that’ll override Octopus controlling the charging via the APIs.
So have just got my first EV - which is compatible with Octopus Igo - and have the Givenergy EV charger connected with wifi - which not only matched my battery and Inverter, but also does not need any additional meter clamps (like Zappi) would - and I thought this would give me full control in a single app.
I do have a Wonderwatt subscription, but have just asked them to cancel this (was on Agile) and I don’t really want to pay £60 PA just to stop my battery discharging when the car is charging.
My battery only discharges if Igo sets slots outside the 23.30 t0 05.30 period where I have my battery set to charge to 100% in the inverter settings.
I have in EV charger the slider on for charging when plug is connected to car.
Until Intelligent Octopus sees the car online, the car will charge, until Octopus somehow tell the Givenergy Car charger to stop charging until the times of the charging slot - suspect it’s the car that does this - but not sure.
Ideally Giv/Octopus would get together and have the charger configured to work with Igo.
I know I can manually just set the charger and car to charge in the 6 hour slot - but going to persevere with Igo and Octopus app for now. So far I still have 100% Giv battery at 05.30 in the morning.
The only other way I could see to stop battery discharging on Octopus slots outside set battery charging period is to increase the battery minimum reserve % when the car is being charged. Fidly but this should work?
So I have tried it like this (EV charger Plug & Go - Octopus App with smart control) with my Audi Q4 E-Tron. Had it just over a week.
Last night plugged the car in early - had 2 IO slots first one was 23.00 hrs - the car started charging at around 18.45 hrs (so would have charged fully at normal price 27p per kwh) - the Octopus app says it may modify schedule - but schedule first slot was still showing 23.00, so I aborted the charge and charged it manually before I went to bed.
I did try charged times slots in car and Giv EV charger but kept getting red technical errors on the car - which I think is not proper comms between car and charger.
I think I will try it with only pretty small amounts of charge to see what happens. Going to start keeping a log.
I have been in communication with Octopus - hopefully they will persevere with me.
Anyway going to persevere and try and get Igo working -
So I have been struggling with charging for a couple of weeks.
No issue with plug and charge - works fine - no issues.
Could bot get Igo charging to work.
Then decided to try a timed charge. In my 2024 Etron - the timer settings are in the advanced charging page - and quite easy to set - when I set these I thought this was it done - but alas no still got red technical errors - error in charging infrastructure.
There is also an option to set a time you want the car to be ready in the MyAudi app - and sometimes it was being set 3 days in advance.
Had a good read through the online car manual - and the manual in my app says my advanced charging page should look like this (hope image works)
Anyway my advanced charging settings page looks nothing like this - and the enable timer button which I have circled in red is on the normal charging page - and you have to click it and ensure the top bar goes red to enable timed charging - and it worked perfectly.
The EV charger was set to plug and charge - and when I plugged in the cable - the white status light flashed then changed to steady white so I assume the car and the EV charge comms were set and EV charger was waiting for command from car to start charging.
The picture below was what MyAudi app showed
So next time I charge going to try same setup except enable the car smart charging again on the Octopus app - and then hope Octopus send new charging widows to the car which then works with the EV charger. Wiill post back results.
So last night I left exactly the same settings. I enable the car as device in Octopus app. I set the end period in Octopus App to 05.30 - same as car.
When I plugged in car, where previously the Octopus App would show the actual charging window schedules - this time it showed “Smart Charging Ready”
My car charged starting at 23.30 - might have been a couple of short breaks but charged to 80%.
I have sent my screenshots top Octopus - who have told me by email they did not think the Igo could override car timer settings, but I am now wondering if you could widen the car charging window - and then Octopus Igo will tell the car when it wants it to charge. The car is stated to be compatible with Igo.
Obviously there are benefits to letting Octopus charge outside the 6 hour charging window if they want to,
Will post any updates. Not on my laptop so cannot post the screenshots.
Thanks that’s very useful, going to try that myself. seen on a forum somebody had it working by setting their Q8 to charge like next Wednesday in the car and then OIG worked for them. so many variants here hahaha
