Sleep algorithm change?

Former Member over 9 years ago

Hello,

I have noticed that starting about November 1st my daily sleep tracking started including evening TV viewing, prior to going to bed, and sitting at breakfast. The analysis appears to have raised the threshold for movement to turn off remove the pre-sleep and post-sleep sections. It also appears to be completely ignoring the user defined sleep and wake approximations. The sleep graphs literally show a few hours of sitting and pink movement spikes to get a drink during TV watching, movement pink lines in my bedtime routine (15-30 minutes or more), and movement lines in my wake up routine with an elapsed time far greater than my actual sleep.

This change has made the Sleep Tracking function useless.

This had not been the case and I was actually quite pleased with the accuracy of the sleep tracker prior to this. It beat the Polar system hands down (part of the reason I am now a Garmin customer).

I updated my Garmin Forerunner 25 from firmware v2.7 to 2.8 around Oct 29. I don't know if this is a firmware or Garmin Connect issue.

Please advise for a solution.

Many Thanks,

SciPop

I am having the same exact issues with my vivosmart.

Same problems with Fenix 3. The weird thing is that even when I manually put the clock in sleep mode, it doesn't matter. Last night I "started" my sleep ~0025 and woke up at 0700. But when I checked the data from my phone, it showed me sleeping at 2337 and woken up at 0702.

At the moment this is just useless, since I need to write down the real times myself, if I want that part to be accurate.

I've had similar issues since auto-sleep mode was implemented but I just accepted it and do a minor tweak in the morning when I wake up. However, what I have noticed for the past month or 6 weeks is that it will report sleep time in the morning but a few hours later, it has changed to a different result.

As I've been looking more about the sleep metrics and if it's working, I must come to a conclusion that that data is completely useless now.

I've made my sleep-time start at 2200hr, and end at 0700hr. Still as I look at the metrics now, it shows me that I've been sleeping today from 1952hr to 2253hr(!). It's even more weird since it's only 2251hr at the time I was checking. So GG Garmin, you've broken one of the reasons I actually switched to your device from Suunto/Polar. And yes I know people don't give a s!"€t about the sleep metrics, since it isn't that scientific or what ever. But in my case it's been more than helpful to have the data.

Hopefully they'll be able to fix this. Otherwise I need to figure out if I'm going to invest more at this ecosystem, or if I'll be switching to something else.

Same on my vivoactive. I manually turn on and off sleep monitoring, but that seems to be ignored. I sync to the app, then have to manually edit times.
