Does the Xiaomi Smart Band 9 Pro support high or low HR alerts?

The Xiaomi Smart Band 9 Pro supports high or low HR alerts. If your heart rate reaches the preset alert level while at rest (non-activity state) and remains elevated for 10 minutes, the band will vibrate to notify you. The high heart rate alert can be set between 100 and 150 beats per minute. This feature requires enabling continuous monitoring to be set to smart monitoring, or intervals of 1, 10, or 30 minutes.
To enable this mode, please refer to the following methods:
1. On the band, you can go to the heart rate APP in the application list and tap to view the current day’s heart rate details. Scroll down and tap [Settings] to set [High HR alert] or [Low HR alert];
2. On the Mi Fitness APP, you can go to [Device] >> [Fitness and health] >> [Heart rate] to set [High heart rate] or [Low heart rate].
