EV tariff increases the daily tariff !

[BarryH]

The other thing to remember is the whole house runs at the lower rate, not just the EV charger so if you have appliances with delay timers e.g. washing machines, tumble dryers and dishwashers you can run those more cost effectively. Might even be cheaper to heat a water tank with a low rate immersion heater than gas (but that would need some spreadsheetery to confirm)

I now have a Heat Pump and heat my hot water using that at night which has a 250% efficiency for hot water and that at the 7p IOG rate. My heating also boosts and over heats the house (excluding the bedrooms) building up heat in the fabric of the house walls thereby reducing heating needed in the fist part of the day. BUT even before I had a heat pump and used Gas Central Heating, I moved every thing I could to the off peak hours and achieved 65% use off peak then I added a little bit of solar and a 10 kWh battery (9 kWh useable) and got to 98% off peak. Now I've a heat pump I back down to 65% in winter but 95%-98% for the bulk of the year. And for for a substantial part of the year I'm also exporting surplus Solar PV generated kWh. Even as late in the year as October my Octopus bill showed £40 export and £60 import so net the house is low cost to run. Sure I invested in Green Tech but under £10 over 2-3 years which is less than my car depreciated over the same period.

Your car API is linked to the app

Is it? How does that work?

Is it? How does that work?

If you have a compatible car

Audi: All models
BMW: Most models (i-series)
Cupra: All models
Jaguar: Most models
Kia: All models
Porsche: All models
Renault: (post-Oct 2020),
Seat: All models
Skoda: All models
Tesla: All models
Volkswagen:

They share their API with octopus and it means they can link in with your car directly, it reads the cars state of charge.
Instead of picking a % to add you pick a % to charge to (80% for example)
I can do it both ways by car or charger as I have an ohme, similarly the ohme knows my cars state of charge so charges to a limit.

IOG was originally just this way, it wasnt until they added compatible chargers that people could use other car brands

I'm probably being daft here, but what's API ?

Car data application programming interface (API) enables interactions between a vehicle application and other applications or platforms

MG have refused access to theirs

Oh, I see, you weren't talking about MGs.

No it was about a guy with IOG a Tesla and a grannie charger

 

[Rolfe]

I see that now, thanks.

Re: MGS5 and (some) access to its API.

Somewhat to my surprise I recently discovered that the ev.energy app which controls my Rolec Charger actually receives at least basic data also from my S5, even when the car is not plugged into the charger. I've just checked the app again and it reports it connected to my car "4 minutes ago" and it's definitely showing the correct battery SOC (the car is not plugged in).

???

Never heard that from a member before, it might be worth folk checking their chargers, certainly with S5s.

It's octopus MG need to share it with though and they are still definitely not on the compatible vehicle list.

 

[Gomev]

My Rolec connects to my Hyundai via the Ev.energy app showing SOC but I suspect it's because I linked my Hyundai account to the charger. The Hyundai is the same as MGs in as much as it not IOG compatible and curiously not the same as Kia, which is compatible. As can be seen here the info on the Ev.energy app shows current data from the charger and SOC from 1 hour ago even though the car has been unplugged for several days.

Interested in that. Do you mean that the heat pump uses only 40% of the electricity that an resistive immersion heater would use? Also do heat pumps heat to 65-70degreesC which would be needed to heat up a hot water tank to a safe temperature?

Maybe not directly though enode (3rd party car data aggregator) are claiming beta support for some MG models (see https://developers.enode.com/api/capabilities/vehicle). Not sure whether IOG use enode at all?
