UK relevant for sure but as the data must already be stored to show the slots it should just be a case of displaying the values based on the DNO setting. I presume that anyone outside the UK would not have a DNO set?
Perhaps current and next two 30 minute slots could be shown; this may allow people to decide to change their charge schedule if they see their battery level is lower than they want/need (and I suppose it could affect discharge decisions as well).
