The LED on the front of the Omna is flashing green, what does this indicate?

A flashing green LED indicates that the camera has been removed/unpaired from your HomeKit controller (the iOS device you used to install the camera). You should reset the camera to factory default using the reset button on the base of the unit, and re-install the camera using the Omna or Home apps.
