Sense 2 - Sleep suddenly not recalculating

[Dr-M]

Hey gang.

Unfortunately, it seems my Sense 2 has stopped calculating my sleep correctly. I've had it for 2 and a 1/2 years, so not a noob - but the sleep stages and sleep score are not recalculating when I try to edit sleep.  One of the cool parts of the Fitbit is that you can go back in and edit sleep. I have historically used this edit sleep and delete sleep features and it worked pretty flawlessly most nights on recalibrating and recalculating.  Now when I try to edit sleep, it just goes back to exactly the same bar of sleep stages, the same sleep score and nothing recalculates?

This only started in the last week to 2 weeks, if that helps locate the change, or update potentially on your side.  Something you can roll back.maybe?  If not, I have no idea what the issue would be, and appreciating your support.  Thank You!

I've just checked and yes, it has started working again, at least for
now. Not wanting to sound churlish but wouldn't you think Fitbit could
have acknowledged the issue and kept us updated via this thread, rather
than someone finding out by accident and then spreading the news
themselves ?

Just tried and mine worked too!!  A poor night of sleep now just slightly better, haha!

Yes, mine just worked as well. In fact I was able to edit my sleep for this morning and it and I had to force it to recalculate, but it did add some time in. I went back to a few days ago when I was pretty sure I slept longer than it showed, and I edited that day and then forced it to recalculate and it also added more to sleep time in for that day as . Hallelujah

Yes!  Unreal.. but hey, early Xmas present.  Too bad most of us have looked into new solutions that might take us all away, already.  😉

Thanks for confirming all..!!

Yes looks like it's back to how it was. If you edit the sleep times now the graph itself shows the new times and calculations again, like before. Also, if wanted, we can re-edit older sleep times and it will update it correctly now. I did a few. That said, they still only have one setting, which is 'Sensitive Mode', and that's it. Even though Fitbit gives you two options, Sensitive and Normal mode, only sensitive mode works, regardless of which one is chosen. That means that any movement is counted as awake time, even if you're not awake. Basically, from my experience (10 years now) we are probably losing 35 minutes a night of actual sleep time by being stuck on Sensitive mode, which started in late June of this year, 2025. Maybe eventually they will fix that as well, especially since it's still an option under sleep settings. I can live with this good enough!

I'm so glad I read some of your reports of some success on this.  Since Dec 1 the sleep tracking has worked pretty well for many nights, except maybe 6 of them.  I was able to go back and "correct" the ones with errors. I could tell which ones because I had already used the sleep editor to put in the correct times even tho it didn't put in the Sense2 data.  I had to do each one 2X, but maybe that was because I didn't wait long enough for the sync to take place.

Most amazing was that Dec 3 & 4 are now corrected.  They had shown "no sleep" at all because I got up too many times, and apparently sleep less than 3 hours wasn't counted at all.  But it is there now!

I have been looking at the new trial app every day.  It analyzes the sleep and the AI gives a report about sleep quality.  I find it amusing because it is obviously programed to say positive things about my sleep pattern, which is not enough REM and DEEP sleep.  As if I know how to change that. Ha ha.

Thanks for the heads up, I'm able to edit and have the sleep score update again!  I did have to edit my previously edited entries again before they would update the score though, didn't have to change anything, just click edit, fiddle with the time enough to register a change and then save.

Yep!  Can confirm!  Mine suddenly started working a couple days ago, I think, because I added a missed timeframe and actually got a graph and score!  I’ve edited two days in a row now (it still doesn’t pick up the entire sleep time consistently) and it has updated the graph and score just like it used to!  I thought I was dreaming, too!  I don’t see that there have been any “updates” recently, either.  It just suddenly decided to work “out of nowhere”?  How does that happen?  Maybe the Fitbit “gods” decide they didn’t like the fact that I ordered a different brand watch? 😝
