Sleep tracking issues
-
At the end of a week, my Suunto Run 2 shows me an average of 90% light sleep. That doesn’t seem right. In addition, my two previous watches from other brands (Apple and Coros) always showed me an average of 50% light sleep. The watch measures HR throughout the night and gives me a higher average than I had on the other watches; as for HRV, it only measured on four nights.
I contacted Suunto support and, regarding sleep, they told me it could be a defect with the LED lights. They gave me a set of recommendations (such as wearing the watch tighter) to test in the meantime and offered to replace the watch.
Question: is it normal for sleep tracking to take some time to calibrate at the beginning, or does it really make sense to start the replacement process? Or should I hard reset the watch and see if it helps?
-
@gogapo not sure if it needs to calibrate but for me it measured first night with R2 like this:
It looks normal to me. I was awake for few minutes when i checked time in night watch didn’t catch that but previouse suunto didn’t either too if i don’t stand up and walk.
-
And i would consider myself light sleeper. Rain/Cars/Elevator noise can wake me up usually in night.
-
@Tomas5 my Coros measured and average of 57% of light sleep since the first of January until the end of August. My Race 2, which has one week with me, it’s giving me 90%, nothing like yours. So I can try a hard reset or start the replacement process. Or a return process, I have to think about it.
-
@gogapo well try that reset it may help, but if it will not resolve issue for you than i would follow suggestions of suunto support you contacted and ask for replacement when possible.
-
@Tomas5 I’ll do the hard reset and see if it works. And thank you for your inputs
-
I was literally awake from 11pm-12:15am, walking around, and it said I had no awake time lol. It’s pretty bad IMO. It gets when I first fall asleep and wake up, but that’s about it
-
@burrowsnp for me it had hard time to detect exact time when i fall a sleep or wake up, it captured when i stoped moving not when i actually was sleeping with my older Suunto 5. Now with Race 2 i think it is same that it captures when i stop moving, but doesn’t know that i try to fall a sleep for 20-30minutes. And about awakness during night. With S5 it usually detected when i was walking for at least 5 meters. But not everytime. Now with Race 2 i was awaike druing two nights, both time i checked time on watch and went to toilete, once it didn’t detect anything and once correctly detected that i was 4 minutes awake. So for now 50/50 but i have watch only few days. And from what i can tell today it correctly guessed las REM because i was waked up by alarm in middle of dream and it should mean i was in REM and it showed correctly i was in REM in that time.
-
My first night after resetting the watch: half the night it shows nothing, no HRV. I’ll give it a few more days, but if it doesn’t start working properly, I’ll contact Suunto and return the watch. I really love some things about the Race 2, but others are really annoying
-
@gogapo have you checked if the H24 HR tracking is still enabled? if disabled sleep tracking doesn’t work
-
@Tieutieu it’s enabled and it measured heart rate all night long. But not sleep and HRV
-
@gogapo have you tried to set auto dnd mode to same hours than sleep tracking ?
My settings (race S) : 7 hours sleep target time. Sleep time set from 11pm to 7 am, same for auto dnd.
Never had a failure with sleep tracking.
-
@Tieutieu I have both set to the same time. Before I did the hard reset, I never had such a gap — it’s the first time. The problem was that almost everything was counted as light sleep. Let’s see what happens in the next few da
-
@gogapo ok. Can’t advise more, hope it will work well again.
-
@Tieutieu but thank you for all your help
-
@gogapo any changes?
My race 2 gives me 2-3 hours of deepsleep, which is not true! Worst ive ever had. Ive measured it with both polar v3 and helio bad which estimates around 1-1.15h evry night.
-
Sleep tracking without reading brain activity is every time just guess based on your HR and movement. For me after multiple nights i can say that Race 2 are really optimistic, as soon as i don’t move it counts it as sleep. And i don’t have any equipment to validate if REM, Deep sleep/Light sleep are correct. It is more “fun” feature than proper scientific measurement. I think best what we can take from sleep is night HR, and HRV readings.
Suunto Ambit 2 > Suunto 5 > Suunto Race 2
-
@Tomas5 My watch didn’t record HRV on most nights, unfortunately. Just twice
-
@gogapo it works for me every night
-
@Tomas5 yes i know, but every other watches have given me around 1-1.20 h deep sleep (including AWU which is around 80% correct compared to medical grade dquipment). When suunto then give me 2-3h deepsleep it keep showing recovery around 90% all the time, even when i sleep 4-5h.
I dont care if its not 100% but a ball park would be great as they keep providing guidance based on sleep score o
