The scale will keep Bluetooth active when it is running or within 10 minutes after the user steps off. The scale can store up to 100 readings and once a smartphone is connected, the data recorded on the scale will automatically sync to the smartphone.

For the Smart Scale P2 series and P3
Yes.

Smart Scale P2 series and P3 are Bluetooth and WiFi dual-mode devices. If you are connected to WiFi, the data will be automatically saved to the server after the measurement is completed. You can view the data the next time you open the Eufy app.

If you are not connected to WiFi, data transmission must be done via Bluetooth. Bluetooth will remain active when the scale is on or within 10 minutes after the user steps off. During this period, once the scale is successfully connected to your smartphone, the data recorded on the scale will automatically sync to your phone (the scale can record and temporarily store up to 100 readings).

If the scale is not connected to the Eufy app on your phone, the measurements will be recorded on your scale. The next time you open the Eufy app, the data recorded on the scale will automatically sync to the smartphone.
