You are probably using the stamina battery saving mode or Extended Standby Mode which prevents Sleep as Android from waking up the device ans so the alarm will not ring if this mode is enabled.
For stamina mode, you can either disable this mode or add Sleep as Android to the active applications in standby. The option resides in settings->Power management. To add Sleep as Android to the active applications in standby, click on “stamina mode”, then “Add applications” and check Sleep as Android.

To disable Extended Standby Mode, go to settings->Power management and then uncheck Extended Standby mode.

Noise & Snoring

Please check that you have enabled noise recording in Application settings → Sleep noise recording. Noise recording in not enabled by default as it causes slightly increased battery consumption during sleep tracking.

Next please check your Application settings → Sleep noise recording → Recording volume threshold you may want to lower your threshold in order to get more recordings, 20% is the default but 10% may be a better match for your device.
Also Application settings → Sleep noise recording → High quality recording is good to enabled as it features a better algorithm to capture significant noises.
Next try to adjust the recording threshold. You can start very low – for example 5/100…If you start sleep tracking you see a recording progress bar at the top. There are two indicators, one shows the actual threshold and the other the actual recorded level. When even the second line gets over the first line recording starts.
Please do a loud noise to calibrate the scale and then try to make a normal noise you would expect sleep talk would be during night. If you see your talking is getting recorded (red icon to the left) than you are setup. Otherwise please try to adjust the recording threshold.
In case you are still suffering issues please send us a debug report (Alarms tab → menu → send debug).

Sleep tracking

Huawei together with Xiaomi are the most troubled phones on the market, some vendors tent to ignore Android best practices and implement very bizzare custom modification which make background task nearly impossible to run.

From various error reports we know that the accelerometer sensor implementation on some firmwares has issues. Over the time the accelerometer may get into a broken state and it stops sending data. The only way we know to resolve this issue is to do a reboot. In all cases so far, reboot did solve this issue.

To test whether the accelerometer is working, you can use menu > test sensors or some 3rd party app such as Sensor List.
