Blinking light on motion

(Ken) #1

I was wondering if its possible to make a cree connected bulb blink on and off when motion is detected. My purpose for this i have a motion sensor outside the back door and outside the front door. At night after a certain time I would like to make a rule that will blink my cree connected bulb 3 or 4 times when motion is detected. Further more, what would make this even more neat would be if the number of blinks could be different if the front motion is tripped or the back motion is tripped. Say for instance 4 on/off blinks for motion detected in the front and 7 or 8 blinks for motion detected in the rear. Is this even possible?

Nice little app. Works great. I like it for use with Smart Alarm. Should scare the bejeezus out of anyone in addition to the siren.
