Blaze won't sync sleep or heart rate

[Melissa824]

I've had my Blaze for a while, but just recently it stopped functioning with the heart rate and won't track my sleep. Any suggestions please?

Hey @Melissa824, welcome to the Community.

If your Blaze isn't registering your heart rate information, I recommend taking a look at this post, where you will be able to see some things that might be affecting this reading and some tips to improve it. Now about the sleep, there are a few scenarios where you might see your sleep pattern (which shows your time asleep, restless, and awake) instead of sleep stages:

• If you slept in a position that prevented your device from getting a consistent heart-rate reading or wore it too loosely. For best results, wear your device higher on your wrist (about 2-3 finger widths above your wrist bone). The band should feel secure but not too tight.
• If you used the Begin Sleep Now option in the Fitbit app (instead of simply wearing your device to bed). For more information on automatic sleep tracking, see How do I track my sleep?
• If you slept for less than 3 hours.
• If your device’s battery is critically low.

Let me know how it goes.
