The app should have a summer mode which, once activated, amends all schedules down by a predetermined amount, to counter ambient temperatures. For example, 22 degrees in winter feels comfortable, whereas 22 degrees in summer feels too hot. This is due to ambient temperatures, which affect heat retention. Now that temps have increased for summer, I either have to turn off all rads, or manually adjust them all down. It would be great if summer mode could just amend all schedules at once.
