体重計の接続方法を問わず、体重を測定した数分以内に同期されます。Withings Health Mateアプリでデータを確認することができます。

Wi-Fi measurements are uploaded within 60 seconds of any user weighing in. When a scale is configured for Bluetooth use, measurements are synced only when the mobile device used to configure the scale is within Bluetooth range (about 10 - 20 feet or 3 - 6 meters) of the scale.

If you don't have Wi-Fi where the scale is located, consider setting up your scale with Bluetooth.
