If the SmartDrop cannot be added to the eufy Security app, please try the following steps to verify if the issue can be fixed:

• Make sure the SmartDrop is connecting to a 2.4GHz WiFi network (eufy SmartDrop only supports 2.4GHz WiFi).

• Fully charge the battery of the SmartDrop with a 5V/2A charger, and then install the battery back in the SmartDrop.   

• Check if you can hear 2 beeps when you scan the QR code in the app and ensure the environment is not too dark to scan the code.                  

• If the app shows "Failed to scan", please follow the app instructions to "Scan for code" again or manually enter the code. 

• Reset the SmartDrop by pressing and holding the SYNC button for 12 seconds until you hear 2 beeps.

• Try to set up the SmartDrop using another mobile phone.
