Sleep is a FREE feature, you never pay for any sleep feature. PRO license is for other features (notifications, workouts, ...)
If you are running a recent firmware version on your band, you should use default or V6.2 sleep analysis version to get results similar to official app (results may be different).
Please first always sync data on notify app and then on official mi fit app
Disable "Wake up notifications" and "Activity stats notifications" on official Mi Fit app
Sleep parser Airplane or Do not disturb phone modes will prevent calculated any sleep data from band data, so first please ensure you have Default sleep parser mode enabled
Sleep during day time
Mi Band doesn't support sleep tracking during day time, on notify app there is a beta feature to allow calculate sleep also during day time. You can enable that option on sleep more options.
We suggest use sleep analysis V4.7 to track sleep better during day time.
Sleep statistics is different compared to official app
Notify app uses a different sleep algorithm to calculate sleep statistics. So you may get results different compared to official app.
We suggest use the default sleep parser (V6) to get best results similar to official app
Some sleep data is missing?
1) Ensure data has been synced from band, if not you can force data resync like showed below or just skip to next step
Please notice, this tutorial works only if data is still saved on band. If data has been deleted by official Mi Fit app, or by repairing band, or after a firmware update, you will not be able fetch the old data.
2) If data has been synced correctly, you can proceed with sleep re-calculation:
How change sleep analysis version
New notify version 5.5.6 added new sleep analysis V6.2
If you are using an old firmware version on your band you may need choose an older sleep analysis version like V4 or V2
You can change the sleep analysis version on sleep more options
Please notice V1, V2, V6 versions are cloud bases, it means an internet connection is required. NO DATA WILL BE SAVED ON CLOUD, data will be just uploaded to calculate sleep statistics and then will be not kept anywhere.
So data will be kept only on your device, as usually, you have to export a data backup (or enable an auto backup) to keep your data saved if you reset/change phone.
