Hello, you can check whether the current sleep monitoring is on or not by using the message in the following screenshot
To respond correctly to the sleep monitoring state, you need to lie down in a real bed and be in a calm mood, keeping your body as still as possible to simulate the sleep state as much as possible.
If the sleep statue and sleep quality you are referring to are not reported to you in real time, you can check if the feature is responding properly by querying it autonomously
