Then confirm the scale is registered in the Withings App, look for measurements waiting to be assigned, and check the battery before changing the connection or repeating setup.
Start with the app, device registration, and battery
- Confirm Body Scan is listed. In the Withings App, open Devices. If Body Scan is missing, add it using the setup steps below.
- Check unassigned measurements. Open the app menu and look for measurements that have not been assigned to your account.
- Check the battery. Withings notes that a low battery can affect connectivity. Charge the scale if needed, then check whether it syncs. See Withings’ troubleshooting steps for measurements not syncing.
If Body Scan uses Wi-Fi
Make sure the Wi-Fi network is working and the scale is within range of the router. Move Body Scan closer as a test; if that helps, the issue may be range. Restart the router if the network itself is not responding.

If you changed routers, internet providers, the network name, or the Wi-Fi password, update the scale’s saved connection. In the Withings App, go to Devices, open Body Scan’s settings, and choose Update Wi-Fi Configuration. Follow the prompts to select the network and enter its password. The Body Scan Wi-Fi configuration guide describes the process.

If Body Scan uses Bluetooth
Bring the phone used to set up the scale close to it and open the Withings App. Confirm you are checking the phone that was paired with Body Scan: Withings says the scale communicates with the last device it paired with. If you have paired multiple phones, the scale may be trying to communicate with a different one than the phone you expect.

Wi-Fi or Bluetooth-only: which connection should you use?
| Connection | When it fits | What to know |
|---|---|---|
| Wi-Fi | A working Wi-Fi network is available within range of the scale. | Withings recommends Wi-Fi for usability and synchronization. See its Body Scan installation guidance. |
| Bluetooth-only | Wi-Fi is unavailable, and the phone paired with the scale can be nearby when needed. | The setup flow offers Bluetooth-only synchronization, but Withings cautions that most of the functionality available in Wi-Fi mode is lost. |
Repeat setup or pairing
Before starting, have the Wi-Fi password ready if you plan to use Wi-Fi. Turn on Bluetooth on your phone and allow the Withings App to access location.

“Synchronization issue” on the scale display
Withings says this screen means the scale could not sync with the app. Check that Wi-Fi is working, update the saved Wi-Fi configuration if the network name or password changed, and move the scale closer to the router.
