The absence of a sleep breathing score or monitoring data in the Mi Fitness APP is due to the following reasons:
1. First, confirm that the sleep breathing score feature is turned on in the Mi Fitness APP. If it’s not turned on, the data will not be recorded or displayed;
2. If your sleep time is too short or the effective monitoring time is less than the required duration, the sleep breathing score will not appear. For the score to be recorded, your sleep duration needs to be more than 3 hours. If you only sleep for a brief period, the system will not gather enough data to generate the score;
3. Improper placement of the band on your wrist can affect monitoring sleep and breathing quality. To ensure accurate monitoring, wear the band loosely, with one finger's width of space between the band and your wrist bone. If the band is too tight or positioned incorrectly, it will fail to track your breathing and sleep quality.
