Day/Night mode for Smartband

[EmmaP]

Hi,

Would it be possible to have a different auto night mode for weekends?  The app doesn't monitor my sleep properly when I stay up late and sleep in on my days off. 

I know I can turn night/day on and off but the current instructions for the device are pretty bad and I am not sure how to use it.

To toggle between Day/Night mode is a long press of the button - until you feel the vibration.

I turned off the autosleep mode - because I don't go to sleep at the same time every night.  I turn to Night mode when I go to sleep, but I have had times when I forgot to switch back to Day mode when I wake up.  Ended up with no data tracked which is extremely annoying.  The band is able to tell that I'm no longer in "light" or "deep" sleep, so why can't it switch back to Day mode if it can detect continuous activity, ie walking?
