Sleep Tracking
-
s9 here, but the same “issue”:
I had 99% sleep quality tonight, but don’t feel rested & was waking up a few times at night. This is somewhat reflected through resources which use a different algorithm. The core of my consern lies on me never before experiencing this high of a sleep score. -
@jamie-bg guess what happened on May 22nd 🥴

@c1rclez Hello from a fellow WHOOP user! Well, mostly former user… Though I have it on my arm right now to validate Peak, what else?
S9P is nowhere as sensitive to sleep disturbances as WHOOP was, and one might argue if WHOOP was correct. It normally reported me having 10-12 sleep disturbances per night with 30-40 min awake time while I could barely remember any. Now, I get it sometimes you wake up and fall immediately back asleep and don’t remember anything, but I think 30-40 minutes is plenty…
That being said, while WHOOP was probably overestimating the amount of wake time picking up on any movement during the night, S9P clearly misses shorter periods when you are awake, especially when you are tossing and turning.

To answer your original question: the watch would stop sleep tracking upon alarm that you turn off it seems. It would also stop if you disable DND or start syncing your watch with the app.

What does your ave HR post against your sleep, and have you checked your HR to see if there are any major blips on it, showing that you definitely woke.
Maybe your HR didn’t move significantly and if you haven’t stood up, its very likely that it might not record it a wake period. I suspect that in your wake periods it was recorded as light sleep, just like it does if you sit and watch tv during your sleep time, don’t move much and your HR lowers similar to sleep - you get a massive light sleep patch, which goes to wake up when you stand up to go to bed.
So if you do wake and want to see a wake period, maybe move around a lot / stand up…

Yesterday I had an interesting situation.
I took the watch off after bathing around 24:00, put it back on around 4:00 (then it started measuring heart rate again). I went to bed and woke up around 11:30. The watch counted almost 12 hours of sleep! For me, compared to Suunto 7 this watch is not suitable for sleep monitoring. maybe they will fix something in the next update. -
@mlatej it does not base sleep to heart rate. So yeah if you take the watch off during the sleep time it will register sleep. You can also turn off the 24/7 hr and still track your sleep …
-
@mlatej
And I’m pretty sure it is also stated in the user manual -
@sartoric The manual does not say that the watch will measure sleep when you take it off. It does say that it relies on an accelerometer. It makes no sense that when the watch is motionless (for example, lying on a desk) it measures this as deep sleep…
-
@mlatej
I guess the manual has been updated when deep sleep data was added, anyway it actually uses accelerometer as you normally don’t move that much while you’re deep sleeping, so the watch guess it’s “right”
The only way for the watch to start monitoring sleep is to check the sleeping range time and then any movements as it cannot check your brainwaves
-
@sartoric correct.
-
@dimitrios-kanellopoulos Well, it’s not quite like that either
In my watch I have set my sleep time to be between 4:15 and 13:45. In the manual it is written that outside these hours the sleep will not be counted. In my watch, however, sleep is counted outside of these hours… That is why it counted only 12 hours of sleep then, and today, despite the fact that I got up far after 13:45, it still counted it as sleep.
I don’t really know how it works, but maybe I will learn it somehow, or there will be an update which will sort it out
-
@mlatej I truly believe the device has an issue if you wore it after waking up.
Just for my sanity and sorry if you had answerd and didn’t see it so far.
Does the device count steps. ?
-
@dimitrios-kanellopoulos Hmmm, it looks like it’s counting, but I have no way to check if it’s working well except by manually counting the steps
What I do know is that the Raise to wake function works pretty clumsy… I think this function uses accelerometer too. Here I created a thread about this issue: https://forum.suunto.com/topic/6711/raise-to-wake
Maybe there is something wrong with my accelerometer? -
I noticed this behavior with S5. It can detect quite good when i fall a sleep. But it often doesn’t recognize when i wake up. I must get up from bed and walk or move with hands for a while for watch to notice that i woke up. And during night it sometimes doesn’t notice i got up and went to toilete. So if i am away from bed for only few minutes, it often didn’t notice at all. There is room for improvement, but i am not sure what precision can be achivied with these kind of device.
-
@hristijan-petreski totaly agree, same with S5.

Last night wake up, went to kitchen, eat, go to bathroom, back to sleep, still s9p got continuous sleep.
Also I didn’t went to sleep at that time, I may have lay down on bed but was on the phone having a video call and moved.
It is not first time this happens . If I can help the devs let me know.

@andré-faria but it has awake 33h. It won’t segment the sleep.

Ok that is already more clear. But since in the end my real go to sleep time was like 22:40 and not 21:38 (between those timings I was on bed on the phone, moving and as I said , get up, kitchen, prepare something to eat, bathroom) I would think the watch would detect that 21:38 was not at all the sleeping hour.
At least that was what happened when I had Garmin (fr45,245, f6s). Maybe something related to sensitivy of accelerometer? -
@andré-faria hmm
