I have an up to date Epix 2. Great watch. I am coming from an Apple watch 4, I believe, and with that, sleep mode was simple - you activate it when you go to bed, and de-activate it when you wake. Seems like a no brainer. But with the Epix, you have manual activation modes, sleep schedules, and I don't know what else. I had time input for all the days of the week, but if I stayed up past the activation time, the watch goes into sleep screen, which is a pain in the ass if you are trying to do something with it. So I input all days at 0000 to 0001 to try to bypass this. Last night I went to bed, activated sleep mode at roughly around 2200 or so, and when I awoke at 6 to stop it, I see that it didn't actually start until 0200 something. I am trying to figure if it is me, or does the sleep mode on this thing just plain suck. It also shows me getting poor sleep when it does work. I wore the Apple watch one night on the other arm, and it showed better sleep, but not so much so that it concerned me. I am hoping I am doing something wrong, because I would like to get some consistent sleep and sleep pulse Ox readings. Thank you.
