If your weight varied about more or less 3 kg (6,5 lbs) since your last weighing, the Wireless Scale (WS-30) 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 Wireless Scale (WS-30), then you will be recognized again.
