Sense 2 not calculating sleep correctly

[putrbug]

Over the past few days my device inaccurately logs my sleep.  Most of the time it tells me I am not going to sleep until after 1 in the morning.  I can tell you for sure that is wrong and since a lot of the other categories are driven off sleep I don’t know what to do.  Anyone please help.

I'm having the same issue

I'm having the same issue. I have deleted and reinstalled the app.I have resynced my Sense 2 with my phone. Any suggestions out there?

I find my sleep tracking to be off if I am laying bed (reading a book) for a period of time before actively going to sleep.  If I get up and go to the bathroom, for example, then it seems to track the sleeping activity well.

My issue isn’t reading a book.  When I go to bed it’s too sleep and as far as my body is concerned it is sleeping.  I may wake up to go to the bathroom but over all I’m sleeping.  My Sense 2 is not picking it up and that is a problem.

I have this problem too.  I've found out I get better results if I keep my band tight at night,  but it still tends to miss early sleep episodes.  I think it needs a two or three hour block of recognizable sleep before it decides you are really sleeping, so if you toss and turn early in the night, or get up to go to the bathroom, it may decide you aren't really sleeping.  

If you know what time you fell asleep, you can edit your sleep log and put in the correct times, but it may still miss some data, like sleep stages, for that time period.  I know I am an early night tosser and turner, and I get up a lot.  My heart rate doesn't really drop until middle of the night, so Fitbit may not know I have been sleeping on and off.  I seem to remember seeing a setting somewhere  where you can increase the sensitivity for sleep detection.  I don't remember where that was, but I'm going exploring.  It missed my early sleep again last night.  This is frustrating!

UDPDATE:  I found a sleep sensitivity setting in the app under "app settings" and have tried setting it to "sensitive."  I don't know if that will help, but it is worth a try.

I was wondering the same thing since I know I am fairly restless until
12:30 or 1. Thanks for your input.

[Jal73]

I know I am restless until 12:30 or 1 so that may be why Fitbit isn't
picking up the early hours as sleep.

Customer support suggested I change the sensitivity.  Also, make sure the Fitbit is tight to my arm two fingers below my wrist so it can pick up the heart beat.

[Jal73]

Thanks for your email. I will try to adjust the sensitivity.

Setting the sensitivity worked great for me.

I am having almost the same problem except mine shows me starting sleep at 6, 7, 8 pm.  I don't go to bed until 10:30.  This has just started recently.  Did anyone get back to you on what the problem is?

I have had my sense 2 since they came out.  This is a new problem.  I have my sleep set at sensitive. 

[Jal73]

No help. I've given up.

[putrbug]

They suggested I set the sleep to sensitive.  It seems to work better, but sometimes it still has a problem.  One tech told me to do a reset from the fitbit itself.  Didn't really change anything.  After researching the internet, I think it is very difficult for these devices to monitor sleep.  They all seem to have similar problems.

[Jal73]

This was my experience as well.

Why does my Fitbit only track my sleep using "basic" metrics 75% of the time, instead of the awesome sleep stages breakdown every night?

This is my first Fitbit and I've only had it since 9/24, but I was so excited to try advanced sleep tracking (and the cEDA for stress) and see my sleep stages... except I've only seen the stages like 4 times! Even worse, my Fitbit doesn't seem to accurately track when I'm asleep, because I keep having to go into the app and change the actual times that it logs my sleep: last night was the worst offender, in that it logged two separate sleep logs for one consecutive night of sleep. One night it didn't log that I slept at all, and about 1/3 of the nights it thinks I only slept for 1.5 hours, when I got 8 hours! What the hell is happening? How do I fix it? Can I fix this??

Also, apparently I've only gotten 5 minutes of deep sleep total, since 9/24 when I started sleep tracking... It was one night a week ago and it said I got 5min. of deep sleep; according to my watch, I haven't had any deep sleep since then (though again, it only gives me actual sleep stages breakdowns a quarter of the nights). I'm not sure if that's a glitch that others are experiencing as well, or if there's something wrong with my Fitbit, or otherwise.

Does anyone have any tips? My Fitbit isn't too loose/ moving around, it's full of charge every night, and I make sure my device syncs to my app every morning... I'll be sending this to Fitbit customer support as well, but I have exactly 0% hope that they'll help me.

Honestly, I'm really close to just giving up on this and returning it, and shelling out for a Garmin. But I really would rather just get this to work properly...

[putrbug]

My research has found that none of the watches really do a good job with sleep. I would make sure you have the latest update and also try to set your sleep to sensitive.

Two nights ago mine didn’t even track my sleep at all.

Give my suggestion a try and see what happens.

I've done both of your suggestions. No luck. I'm really disappointed with
all the "great" features FitBit advertised.

I have had all the same problems, as have others, so I think the problem is
with Fitbit. Most of the features advertised, don't function as they
should. I'm really disappointed.

Agree, I've tried 3 devices so far and either this device is being abandoned for Google's own 'Pixel' watches (Google owns Fitbit) and they just wanted the patents, or their software team is completely inept! I am a developer with some embedded devices experience and would never be allowed to release such a buggy product. Garmin is in my future.
