For your reference, there is some information as follows:
1. When the scale measures the weight, it is identified with the last weight record of the existing users in the scale or APP to determine whether it is within the range of ± 2kg;
2. If a unique user is identified, this data will be attributed to this account;
3. If the user is not recognized or multiple users are recognized, the data will be judged as unclaimed data and stored in the scale or the APP. During the next connection with the APP, users can assign the data to the correct profile from the unclaimed data library;
4. After claiming the data, the APP will assign the data to the corresponding date according to the time. To query, you need to check the claimed data in all the data.
