..or do I always have to enter manually when I was sleeping? I don't have a regular sleeping schedule so that would be annoying..
This is my personal opinion. You should ask somebody from garmin. I think my watch know when I'm sleeping. I have time of sleep set to 23:30, and I don't have every day same sleep patern. I didn't check exactly to minute when I started to sleep and woke up, but I think it's quite decent result of sleeping in my GC.
Probably is watch using algorithm of your sleep HR and moving and it can calculate when you' re sleeping or not. If you have on graph deep sleep and light sleep and moving pattern, maybe this is it. I don't know.
This morning it didn't get that I was awake already, so I had to shorten the time manually. Also outside of the set "sleep time" I had a short nap and the watch didn't notice either..
The watch doesn't detect sleep on it's own at all. The Connect "cloud" looks at your movement data from the watch and uses that in conjunction with your Do Not Disturb setting to determine the most likely period of sleep.
It's not particularly accurate and I find myself having to adjust my wake-up time pretty much every day. In fact I can perform a sync right after I wake up and set a manual wake-up time and connect may still decide of it's own accord that I stayed in bed for another hour or two longer because Connect thinks I haven't moved. I find I then have to go back in and manually reset the wake-up time again.
This happens because I have a coffee and read the news sites first thing after I wake up, then I take my watch off to shower/get ready for work and then apparently my walk to the car isn't far enough to trigger the movement sensors, so the whole journey to work counts as sleep (if only!).
My old Fitbit surge had plenty of flaws, but it always tracked sleep perfectly. Because of the optical HRM you'd think it would be relatively simple for the watch to determine if you've woken up (and stayed awake) but since all the sleep tracking is offloaded to the Connect system it works the same way for a relatively advanced watch as it does for a simple step tracker.
There is also no way to include naps or multiple sleep periods in a day. I mean that would be nice but I'd much rather they fixed the main sleep tracking first.
Oh ok. I don't use DND at all, since I don't need it to be connected to my phone all the time, especially not at home, so I don't think it takes that into account since it doesn't seem to work better for you than mine does.
Also this day it kind of worked, I says I was in light sleep when I was still awake for 40 minutes, but it's right about the time I went to bed. Also this was 40 minutes before my setup "sleep time zone". That's interesting.
This morning was ok too, logged me as awake 12 minutes after I got out of bed, 2 hours before the end of my sleepzone. I remember shaking something off of my watch arm, so maybe it needs some extreme movements. But then I also initiated the WiFi sync, so I need to further test that.
If I set my sleep schedule to end at 7, when I sleep in I don't get credited for it.
On the other hand, if I set it to end at 9am and get up at 6 or 7 I don't seem to get credit points for sleep because it thinks I'm under stress those last two hours so it marks against me. Even though I wasn't under stress but just laying in bed doing what I'm doing right now...playing on the phone!
