Smart Scale Troubleshooting Guide

Issues connecting upon delivery

Issue: Upon delivery and setup, your new scale may not immediately connect with the Lark app.

Resolution: In order to pair properly with your new scale, Lark must know that it has been delivered. The user can wait (usually a couple of days) for delivery status to update – or – reach out to Lark at support@lark.com to manually update the status. 

Low Cellular Coverage Error (E1 message)

Issue: Scale cannot connect with Lark and displays an “E1” error. 

Resolution: Some users may live in an area with weak cellular coverage—or have low coverage in certain areas of their home. Either will cause connectivity issues. Move your scale to a place with greater coverage, or reach out to Lark at support@lark.com to enable the ability to log weight manually. 

Time Out Error (E4 message)

Issue: Your scale times out after trouble connecting and displays an “E4” error. 

Resolution: Poor cellular coverage in your home or area can cause connection issues. First try moving your scale to an area with better coverage, and reset your scale by uninstalling and reinstalling the batteries. If unsuccessful, reach out to Lark support to enable the ability to log weight manually. 

Low battery Error (Lo error message)

Issue: Scale is unresponsive and displays “lo” error. 

Resolution: Replace old batteries with four new A4 batteries in the scale.
