Mine occasionally charges at a random time, I don't have any solid data for it, it's maybe 1 in 20 charges, but I believe its down to opening/closing the car when it's on timer. The car can go into a sleep mode if left for more than a day and that can be annoying because then the app comes up with an error about exceeding the maximum number of requests, but that's a different issue. The app doesn't like opening from a cached version, if you use an iphone then in my experience its always best to completely shut the app so that it gets a clean data download when it opens up. I've experimented with programming timers from the car and the app, in theory they're the same but in reality I find that the car is more reliable eg i can never turn off "allow battery" from the app for heating. The app is very laggy, so its quite possible that you pressed charge when you didn't mean to and the app showed nothing.
Have you got your minimum charge set to zero, otherwise it will try to start a charge when ever it likes.
The maximum mpg is 300, if you go further in the page you will see it gives the number of miles on battery and on engine, the regen can give a lot of battery miles.
Good that Octopus have added the Skoda, it used to only be a handful of manufacturers unless you bought a specific 7kw charger.
If you want a £50 credit to your octopus account then I can send you a referral link. You join octopus standard tariff first when your smart meter is installed, then once they've got readings up and running you switch to Intelligent tariff.
Charger defo came with mine, it came with a 7kw lead and a 3pin charger. Maybe they stopped supplying them after I got mine, or I got lucky.
Ah ok, 25p/kw and you're using around 8kw each way. The engine does about 45mpg avg so you're probably better driving the car in hybrid mode, but not in auto, and set the accumulator to 50% so the car arrives with 50% battery at work. Then set it to hybrid auto going back. (you need to use the skoda satnav for this to work properly) and if it still has say 10% left with a few miles to go switch it to electric only to use up the last bit.
Have you got your graph for today (12th) to see what the charger did this morning?
