I tried to use a Charger at Tesco yesterday, a Pod Point, could get it to work, need to do a bit of research. Anyway, I calculated that I had more than enough range.
In answer to charging at home, we have Ohme and Bluelink. I appear to have disabled something on the Bluelink app, so the car charges as programmed, 21.30-01.30. The think with OHME is you cannot programme it to charge at these times, you have to say what time you want the car to be ready etc.. which is all a bit complicated. As things stand it works for me.
As to the software update, I have no idea!
