DIAGNOSIS Error 1006 is a network communication failure between your phone and the camera during the Wi-Fi provisioning step.
FIX Follow this checklist. One: Ensure your phone's Bluetooth is ON and you've granted the Eufy Security app location permissions. Two: During setup, keep your phone within 3 feet of the camera. Three: Disable any VPN or ad-blocker on your phone. Four: Temporarily disable your mobile data to force the phone to use only Wi-Fi. Retry setup.
IF THAT DIDN'T WORK The camera's wireless module may be stuck. Perform a hard reset. Press and hold the reset button on the camera for 10 seconds until the status light turns amber, then release. Wait for the camera to restart fully. Attempt setup from the beginning in the app.
HEADS UP This error is almost always related to the local wireless environment during setup, not your internet. Using an iPhone? Ensure you've tapped 'Join' on the temporary network pop-up that appears during setup.
