You know.. you could just set the app to miles, rather than wailing about how awful the app is.
It rests back to Km no matter how many times you change it. I believe @Glos-Guys still does the same.
The charging schedule is set uo to start 00:00 and end 05:30 with off peak tariffs only (granny charger). It may work fine for a day or two then as soon, as I plug it in after this it just starts to charge straight away. It weird as you have to reconfigure the schedule, even though nowt as actually changed. I use a 13A smart plug now with no problems.
