Sleep Tracking

Would really like to understand what triggered the watch to say I only went to sleep at this time.
I was lying down of bed (trying to sleep) without moving at least from 22h. I don’t recall of moving…
Funny that on last posts where I said I was on video call I moved a lot, changed position , turn around, etc and the watch said I was sleeping.
@Dimitrios-Kanellopoulos this start/end of sleep is connected with algorithm of sleep or just accelerometer?
Can’t stop thinking it is related to accelerometer. The same way when we move the watch it doesn’t trigger the light (I kinda need to shake it), I believe for start/end it is kinda the same.
Let me know what you think.

@andré-faria it uses the accel.

What are your sleep times ?

@dimitrios-kanellopoulos - what sleep tracking are the S9B & S9P using? Suunto? Latest first beat? something else?

Dimitrios Kanellopoulos

@andré-faria set it much earlier. 21 .

@jamie-bg Suunto in house

@dimitrios-kanellopoulos I have no experience of the suunto in house sleep tracking, but my experience with the firstbeat one is very good on a couple of watches - any expectation that Suunto would look to roll that out to other watches in the suunto line?

@jamie-bg I dont know atm

Humm, ok Will try it.
Just for comparison. Garmin Fr45 nailed this pretty well. Don’t know algorithm it used. If you want/need some data I can provide it.
Also if you feel useful that I/other users share the info via app feedback or support let me/us know.

@jamie-bg in my opinion if quality of both algorithms is at least somewhat comparable, it would be better to keep working on in-house algorithm rather than using a black box from competitor company.
My experience with s9 sleep tracking was decent enough too.

@dmytro For me as well. The Garmin watches always think I am already asleep while I am still reading. The S9P is much better in this regard. However you do it Suunto, please keep doing it. Just as I already said on my wish list: Nightly HRV would be on top of it.

@patrick-löffler rem sleep would also be nice.

Yesterday my day was different , had to do some stuff on computer and walk around till 22 something.
Went to sleep at 23. Even reboot the watch before to see if it won’t take into account any starting before that.
Apparently didn’t work…or I should read that sleeping starting time is 21h+2h awake?

Hi all,

Just bringing my contribution here. I tried the sleep tracking a couple of time with my 9 Baro and I have to say, it was not working that well. Last test, on a 6h30 night, it counted 15 minutes of deep sleep and nothing else. So, in the end it always says I had a poor sleep. It’s maybe feeling vibrations when my wife is moving in the bed or something?

The next test will be when sleeping outside in a hammock, I’ll be sure to have no “external” disturbances.

This must be very personal, because I get pretty good sleep tracking from Suunto devices. It is very rare I get sleep or wake up time wrong

@isazi Don’t doubt it, but I would like to understand

it’s a bug or not.
is my watch defective or not
since with garmin watches I didn’t had this, how can I help to improve suunto readings , and does it matter to Suunto (can be isolated case and there is also a lot of people who garmin sleep doesn’t work for them)

Wake up times seem to be ok but sleep times not, and don’t think I have a pattern that could fool the watch (like being stationary reading or on the phone or tv)

@isazi when you wake up at morning, do you get up from bed at same moment? In my case if i stay laying in bed, it counts as sleep until i get up. Doesn’t matter i am already awake and moving a little, maybe reading some news on smartphone etc.

@mlatej Garmin used to do exact same thing until relatively recently.

But I would agree: sleep detection should be improved with regards to the watch being on the wrist. I had an opposite problem: I had a watch on my wrist but took a nap. The watch probably decided it was off since there was no motion and stopped OHR. It didn’t happen consistently though. Maybe because my naps were restless, or maybe because OHR interruptions while on the wrist were a fluke.

@dimitrios-kanellopoulos broadening the sleep times helped! Awake times now fit within the actual times I stand up! Thanks

My today experience with S5. Usually watch thinks i am a sleep longer than real value. Today is oposite.

In reality i waked up around 3:00 am i went to toilete and had hard time to fall a sleep again. I fall a sleep around 3:45 am and than i was waken up at 5:00 am by alarm on S5. Don’t understand why watch ignored sleep between 3:45 and 5:00 because it was really hard sleep. Watch alarm almost didn’t wake me up as i was sleeping really hard.

Just for record i have set sleep time from 21:30 to 8:00 so it wasn’t outside of configured first possible sleep and last possible sleep times.
