Octopus energy now supports Porsche for intelligent tariff.

[MrB]

good luck tonight!!

Touché! Yeah, that one might have to go in the utility room…….

Do you have a timer set for 2.30am to wake you up and go down and move the washing into the tumble drier?

Not quite that crazy. But if we need the tumble drier it can go in the following night or run in the day off the fully charged batteries. Works well at the moment

for those using a Zappi EVSE, it looks like Octopus Intelligent integration is now available with it. No need for OI to control the car directly but done via the Zappi now. Should also mean being able to use more than one EV through it

I know. Try getting Octopus to install a Zappi though. I’ve been waiting 3 weeks and still haven’t been offered an installation date

One upside though is they gave me £30 Electroverse credit as compensation to use on public chargers.

I have to say my head hurts a bit with this tariff so looking for a bit of help please.
I’m on octopus go which works well as we have a taycan, an e-208 and home batteries.
OI might be a little better as the window is longer and the night time rate is cheaper.
I quite like just charging up either car for 4 hours a night which is nice and simple. Under OI, would I be better off setting up Zappi or the Taycan as the intelligent device ? Either way, I’d rather turn off the intelligent charging and just stick to a set amount of hours of charging per night.

I have to admit it's all theory for me right now (car should be coming next week!) but I recently installed home batteries and EVSE with Libbi and Zappi from Myenergi. did move to OI (via a friendly spark who let me set it up with his Tesla!)

clearly stand to be corrected with a lot of this

1) the benefit now that Zappi integration is generally available is that you can use the Zappi to integrate OI with rather than the car. Prior to this, you had to set up the car with OI which mean you could only charge that one car. If you wanted to charge a different car, you have to set up the integration with that car (if that car was compatible) each time - a complete faff.

with Zappi integration, OI controls the EVSE and tells it when to send power to your car or not. You typically set how much you need and when you need it by an OI will crate a schedule with the Zappi. the Zappi can be plugged into any vehicle.

2) I'm sure you know that OI can also schedule charing slots outside the 11.30-05.30 window. If octopus deems there's excess demand on the grid if can schedule a charge during the day too.. this is at the cheap 7.5p rate too.

3) as you have home batteries, the longer off-peak window is great for charging them up! also if you can off-load any other household demand to this window, then you can save a fair chunk of change.

4) if you have solar then you can also use outgoing octopus with OI.. means you get 15p for export. so where you might have tried to provide any excess solar generation into your batteries and/or car.. it's now a no brainer to export back to grid at 15p and charge up on the 7.5p cheap rate.

not to say you couldn't turn off the 'intelligent' part either and just make sure of the cheap window!

Thanks - sounds sensible to take the plunge with the zappi then - appreciate the advice !

I’ll be switching to OI tomorrow, ideally using the Zappi to control the charging so I can benefit from any PV surplus, but I note the info from myenergi says you need a stable internet connection to the Zappi. My Zappi is quite far from the router in the garage connected via a radio signal opposed to wifi. According to myenergi, radio should work, but time will tell (I don’t think the signal drops). My hunch is that over the Xmas break I’ll be scratching my head around how I can hard wire the Zappi. ?

This is all correct. The problem is that if OI schedules charging outside of the cheap window (when I also charge my solar batteries) then it takes first from my batteries rather than the grid. I haven’t found a way round this yet. Although since your kit is all MyEnergi you might be able to crack this one

yep, this was the main reason I went all myenergi.. I can specifically tell the batteries not to supply to the zappi.

you could end up in the world of home assistant to manage automations.. but that's a minefield I've yet to step on!

That’s a good option to have. My batteries are Giv energy - but I think they are much cheaper than the MyEnergi ones which will easily make up for any electricity cost savings that a different setup would have given me

The simple approach is to avoid OI integration and all of the inherent dependencies/failure points and just rely on car or charger schedules.
Avoiding drawdown from batteries during the off peak period is a separate consideration. I don’t yet have batteries - does the battery controller have its own switching and scheduling for charging and drawdown?
In the OI App there is a switch to turn off Smart Energy. I assume that turns off charging outside the off peak period. To the same end, if you have used a public charger, remember to turn off Direct Charging on the Car. And also remember that if the charge level is below the minimum you have set , it will charge during peak hours.

Yes, you can schedule battery behaviour or control it manually but I suspect the exact settings available will vary from system to system. You will probably only really know how it functions when you get batteries.
Turning off smart charging in the Octopus app then just goes back to the car and/or EVSE controlling it.

I had my Zappi (and Eddi) wired in such a way they are 'grid side' of my Tesla battery gateway - that way the battery system is totally unaware of the Zappi and will therefore never try and supply to it - car charging will always be from Grid (unless there happens to be solar excess flowing the other way). This also means the Eddi (hot water diverter) and Zappi use dont mess up the Tesla's incridbly clever time-based charging logic and it always charges 'just-enough' to run our house use through the day.

I am on IO and also disabled all smart charging and rely just on the Taycan's timers and profiles. I sometimes also set the Zappi to ECO+ mode - usually when I have a very low SoC and Im not bothered about the car hitting 85% over a single night (otherwise it knows it cant hit the timer target SoC and will charge outside of the 23:30-05:30 cheap window - this forces it to only use the cheap period).

I found IO smart charging was very unreliable - missing targets, over charging targets, or simply not doing anything and letting the car charge during peak period. Also it breaks the pre-heating and the clever topping-off the Taycan does to reach the timer set SoC at the right time and with a warm battery. IO would cause it to stop charging at 05:30 and the battery would be much cooler when you wanted to leave at 9am.

I'd be interested to see how IO integrating with the Zappi would work. For example, L2 charging has NO way for the EVSE to see current SoC - so how would it know when to stop at 85% (for example)? I presume it would rely on car settings for that - which is going to result in unpredictable interactions between profiles+timers and what IO is telling the Zappi to do.

from what I've been reading on the myenergi forums, you specify a %age of charge you want delivered (say add 50%) and OI does the rest. As you are specifying the car make/model at set up time, Octopus know the battery capacity and therefore how much charge to deliver..

as you say, Zappi can't see the car SoC directly
