Sleep Tracking

@patrick-löffler rem sleep would also be nice.

@dimitrios-kanellopoulos said in Sleep Tracking:

@andré-faria set it much earlier. 21 .

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.

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.

@tomas5 Sometimes it does that, capturing only part of the sleep. Then, as you stop moving around, a sync or two later it adds additional hours. As long as you don’t fiddle with the watch enough to get “Good morning” sleep message.

@nickk well i didn’t touch the watch at all during night. But since i had hard time to fall a sleep again, maybe from my movement they decided to show morning message but i didn’t notice.

Patrick Löffler

Probably this has been discussed already. Why can’t the S9P not have the same sleep stages as the S7. Would be awesome if it could. And taking it even further please like Garmin a full night SPO2 measurement.

@patrick-löffler I’d guess it has to do with FB algo licensing and firmware codebase sharing. S9P is effectively a smaller S9B, with a few sweet extras. So, it makes sense it would inherit the exact feature set of the bigger brother.

Jamie BG

@nickk could also be hardware as the firstbeat stuff is all done on the watch and not on the servers…

@jamie-bg Well, hardware doesn’t prevent S7 from having full sleep stages. And yes, I’m aware that S7 is running Qualcomm 3100 and not a custom processor found in the rest of Sx series.

Still, the presence of full sleep stages analysis from FB in lower cost Garmin units would suggest it has less to do with silicon and more with what gets licensed and deployed to the watches.

Jamie BG

@nickk Lower Garmin units do not use the advanced sleep tracking i.e. firstbeat sleep tracking, they use Garmin’s own inhouse sleep tracking, to which all reports I have seen suggest it isn’t nearly as good as the first beat sleep tracking.

Can’t find any details on S9 CPU and memory, so no idea how it stacks up against the top end Garmin and S9 in terms of power and resources and or the 3100 qualcomm chip.

Dimitrios Kanellopoulos

While I don’t know I don’t see an issue s9P using FB algos. However I would personally prefer a better algo from Suunto or a better algo in general as FB is licensed

@jamie-bg This isn’t correct. By lower cost units I mean watches like Venu 2 and Venu Sq, which most definitely have onboard sleep tracking. As do (or should have it soon) entry level Forerunners. I think DCR was quoting Garmin in one of his recent reviews saying the onboard sleep analysis is coming out across their entire device line.

@dimitrios-kanellopoulos I think the only truly better algo that exists out there is Fitbit, and even that doesn’t really give you anywhere close to real sleep phases. I’m not sure it will ever be possible to match lab grade polysomnography with a watch on your wrist. But even if we could do that, then what? How can you make yourself have more REM or N2/N3 sleep?

It’s like those running dynamics metrics. Very cool in theory but hardly something you can consciously change.

I wouldn’t be surprised if in a few years all this faux analysis go back to where it had started a while back: a graph of your sleep movement, sleep/awake tracking (the only thing watches get mostly right), and a general sleep quality score that would take into account many other components such as duration, regularity, restlessness, etc.

Dimitrios Kanellopoulos

@nickk agreed.
