Device not recording sleep

[Slennur]

Everything else is working. Sleep won't sync or show updates. I've force stopped. Logged out. Logged in. Restarted tracker a couple times. This is the second night now. Frustrating.

Hi @Slennur, welcome to the Community Forums! 

First, I'd like to appreciate your effort and patience troubleshooting this situation prior to posting, I totally understand how frustrating this matter can be for you. To better assist you with this, can you please let me know if your device isn't recording Sleep Stages or sleep information at all? Did you experienced this issue in the past or it's the first time? If you haven't already done so, I recommend you to check the information that's specified on our help article: How do I track my sleep with my Fitbit device? and let me know how it goes.

Keep me posted and let me know if you have any additional questions.

Thank you. It won't record sleep at all. This is the first time it's happened.

You're welcome @Slennur, sorry for the delayed reply.

Thanks for bringing this to my attention. Since your device isn't recording sleep information at all, please try the following steps and let me know if the issue persists:

1. Restart your Blaze
2. Use it on your non-dominant hand to track sleep
3. Make sure that the Fitbit app and your mobile device operating system are up to date

I'll be waiting for your reply if further assistance is needed.

The issue is that the flashing light - that normally tracks heart rate is no longer working, hence not tracking sleep. Can I replace that alone rather than purchasing an entire new device?

Thanks for your update and clarification @Slennur, my apologies once again for the delay in responding your post.

Since the heart rate lights are not flashing as the way they were designed, please try the restart process that was shared on my previous post and let me know if the issue persists. If such is the case, please check the information that's specified on our help article: Why don't I see my heart rate on my Fitbit device? to troubleshoot the heart rate sensors of your Blaze.

Let me know if you have any additional questions.
