Couldn't get two cameras to shut off, only grey light on app. Uninstalled cameras, deleted app, reinstalled app, reset cameras, tried to add both cameras, QR times out on both, back to blue blinking light.

We do have two phones running app, deleted the cameras from both apps.

Dear Richard, thank you for the mail.

For iSensor, if it is hardware defective, we normally see blue led is on still and no any response to hardware reset.
Since the blue is blinking as the 'waiting for installation' mode, a good chance to install it well.

Kindly follow the steps below and please reboot the wifi router first.
Thank you
