So I have a “dumb” dusk to dawn patio/coach lamp something like this… http://amzn.com/B002DWAF26 The wall switch stays on all the time. At dusk light turns on to dim, when motion is sensed it goes to bright for 5(?) minutes.
I thought it would be nice integrate this into SmartThings by using a wall switch that can measure energy. A new device type handler would detect the change in energy usage to determine day/night illuminance and motion:
-low to high=night time, generate motion event in SmartThings
-zero to high=light switch turned on, no motion
-low or high to zero=someone turned off switch, turn it back on
Pros versus a standalone motion sensor… designed to be outside, its hidden in the lamp, typically located right by the door, and I already have it
Cons: no motion detection during daytime
Anyone tried this?
