Why do I need to wait for a while after scanning the QR code on eufy C210 Smart Lock?
The time it takes for the eufy Security app to process after you have scanned the QR code on your eufy C210 Smart Lock primarily depends on the signal strength of your WiFi network.
The reason behind it is the device’s serial number and Mac address are securely stored on eufy server, and the eufy Security app has to connect to eufy server in order to validate both the serial number and Mac address of your eufy C210 Smart Lock.
