Question

Why is my light flashing/turning on at night?

Why does one of my X10 lights turn off when I turn another light on?

Is there any way to disable the dawn/dusk feature on my EagleEye sensor?

Answer

This nighttime lighting issue can be caused by the dawn/dusk feature of your motion sensor. When its photo cell detects the change from light to dark, the HawkEye or EagleEye motion sensor sends an On command to the unit code one higher than itself; when it detects the change from dark to light, it sends an Off command.


For example, you have a motion sensor controlling a kitchen light. They are both set to A1. At dusk, this motion sensor turns on a night light set to A2, which it then turns off at dawn. This is perfect for porch lights and night lights. If you do not want to use this feature, you have a few different options:


  • You can stagger home automation codes by using A1, A3, A5, etc. Basically, you don't want anything at a unit code 1 higher than the motion sensor.


  • You can switch up to the MS16A sensors- they can turn that feature on and off.


  • You can also physically disable the dawn/dusk feature. To disable it, open the case and cover the component that has the squiggly line with two layers of black electrical tape. This will put the device in permanent darkness: it will always detect motion, but never send dusk/dawn commands. This does, however, void the unit's warranty.
