Sleep Tracking Question
-
@pikeviewer I have sleeping time set 10:00 pm to 8:00 am. Sometimes, if I sleep longer time and get up later, it tracked my sleeping all this time, for example today it was to 9:33. It is out from set range, but it is true.
-
@mcindr Thanks for the feedback.
-
How about a filter, like if (HR==0) human = false;? And then don’t track sleep if !human? Is this interfering with something else?
-
@pikeviewer it doesn’t exactly end at those times.
The thing is that it tries to detect if you went for ie bathroom and then back to sleep or woke up.
Without being precise on what I say it looks pretty much to 30 mins after starting Todo an activity ie walking to see if you are going to sleep again.
-
so, I didn’t take the watch off last evening, then went to bed the usual time. It worked the way it should, showed me asleep at 11:00, awake at 7:14.
So, it works properly if I don’t take it off, doesn’t work properly if I do take it off for a while before bed time. Any other variations to try?
I’d still like to know whether anyone else can reproduce this.
-
@pikeviewer I’ll test this tonight.
-
Great. I tried it again last night, this time having my watch off my wrist one and a half hours before bed time for an hour, then putting it back on. In the morning my watch again showed me sleeping starting when I put the watch down. I’ll look forward to your results.

Hi,
Also, I would like to ask about “awake time” on SSHR, because it always shows me 0:00, and woke uptime is always the same as my Alarm clock?
-
@Michał-Rudzki
If you usually wake up when the alarm ring, well, it’s working as expected. If not, maybe you’re just laying in bed and not sleeping and maybe, sometimes, it’s simply not tracking it for whatever reason
The awake time set to 0 means that, in those 7 hours, you’ve always slept.
-
Well, I seem to have found a work around. Last night I set the watch down for 1/2 hour, 9:45 to 10:15,then when I picked it up I didn’t put it right on my wrist. Instead, I flipped through several screens, looking at my immediate heart rate, stress level, steps, etc. I figured that that activity might stop the watch from thinking that I had been asleep.
This morning the watch showed me as asleep from 10:45, the actual time that I have set for sleep tracking to start. I was reading in bed at that point but apparently was still enough for the watch to think I was sleeping.
I’ll try repeating this procedure tonight to see if it is consistent.
I still think the programming in the next update should address this somehow.
-
@sartoric the problem with that is the fact I missed the alarm clock and didn’t know that the alarm starts beeping. I woke up 1.5 hours after the fact I woke up physically.
-
@pikeviewer I tried this and cannot repeat your issue. However, I do not immediately fall asleep. Do you have activity tracking turned on as well?
-
I don’t fall asleep immediately either. Not sure what you mean by activity tracking. When I go to the activity settings, I do have steps and calorie targets and daily heart rate turned on but activity notifications off.
I used my workaround again last night and it did again prevent the watch from “thinking” that I went to sleep early.
So, at this point it is not a problem for me. I’m just curious whether it is a software bug, something particular to my watch or something unusual that I am doing. Maybe some other users will see this topic and try it.
Thanks again for trying. You might want to try it again just to check, but otherwise, let’s look forward to a better 2021!
-
@pikeviewer Wanted to replicate your settings, I have activity and goals but have notifications turned on. I will turn those off and see what happens.

@pikeviewer sleep tracking is not much accurate. I have this watch for few weeks now. Today for example i stayed in bed longer as usual. My watch measured start of sleep quite well. I don’t know how to check deep sleep length but it may be correct. But at early morning i wake up few times and at morning i wake up but stayed in bed for an hour. But in watch i have all this time counted as sleep. With Time awake: 0:00. But i am not sure if any device on market can measure this correctly. This kind of feature should be called bed time tracking and not sleep tracking because even if you don’t sleep. While you don’t move, it is counted as sleep.
-
@tomas5 , and that is why all reviews have shown that sleep tracking is bad compared to a proper sleep clinic. Only really accurate bit tends to be the sleep duration. Fitbit does well on this, and possibly has one of the better estimates of sleep stages.
You need to check/measure brain waves (amongst other items) to confirm sleep stages. Though if you don’t urinate during your sleep period, most of it probably is fairly deep, as when sleeping deep your body releases chemicals which help to reduce the need to urinate. If you are getting up during your sleep period to urinate, its shallow sleep. But quite when or if you have deep and when or if shallow, a wrist wearable cannot determine it.If you have a CPAP machine you will get a very good estimate of duration, and potential of deep/shallow sleep, which is predominantely done based on apnea incidents.
-
@jamie-bg yes i completely agree that wrist device is not capable to determine this accurate. I think that when taking to consideration limitet sensors of device, watch is doing good job. But it is more for fun than for real tracking.
-
@tomas5 - fun yes/no. You can still interpret quite a bit from just the duration - which can always be a good start. HR rate to a degree can assist, but difficult as only 1 part, and your HR can drop up to 40bpm and not mean anything.
Making sure duration, start and end time are good can be a good start. then adding in other data like what you drank etc and what you did prior to the sleep can help build a basis on sleep duration.
But still nice to know, and useful if you have other devices data that you can add to tracked duration etc - can start to make the data more meaningful. -
@jamie-bg from my experience it can track when i start to sleep. But wake up time is incorrect. It measure when u get up from bed but not when i wake up. This morning i stayed around one hour in bed after i wake up. I even truned backlight but still watch think i slept until 6:45am but i slept only until 6am. But watch don’t have possibility to understand difference between sleeping and staying in bed while not sleeping.
-
@tomas5 Obviously that isn’t ideal, but not necessarily surprising.
I had trackers that use to register me as sleeping when i was watching tv, as was still and HR dropped significantly.
Probably your best option is to at least stand up so there is significant movement for your watch to at least register that it isn’t just restless sleep.
As stated drops/increases in HR don’t necessarily mean you are awake/asleep.
This stufff aint easy which is why proper ECG, brain wave are measured, blood oxgyen, air pressure and sensors on all limbs, torso and head are used - including actual observation in a sleep clinic to determine sleep and sleep stages.
