If your weight varied about more or less 3 kg (6,5 lbs) since your last weighing, the Wi-Fi Body Scale (WBS01) may not recognize you anymore.

In this case, you have two options:

• Open Withings App and select Unassigned measurements
• Enter manually the new weight by selecting Add a manual measurement

It will take another weighing to send the new information to the Wi-Fi Body Scale (WBS01), then you will be recognized again. 

Note for Baby mode users: If the weight of your baby varied about more or less 500 g (1,1 lbs) since last weighing, it may not be recognized by the Wi-Fi Body Scale (WBS01). You will have to add the new weight manually in the Withings App and weigh yourself again to sync the Wi-Fi Body Scale (WBS01).
