Minotaur Engineering's adjustable X10 sensor can trigger a Powerflash based on how much light or darkness is received. It automatically adjusts to environmental conditions instead of strictly on a timer and both light or dark can trigger the sensor.

X10 PRO's Mini Timer ( Manufacturer item #XPMT4.(aka MT13A)) controls up to eight X10 Modules instantly or automatically. You can have your outside lights as well as your inside lights and appliances go on and off at preset times to give your residence a lived-in appearance while you are on vacation.

X10 timer switch!!! Never heard of them! I guess you might have read it wrong. We all know many products which are similar to the Leviton Decora. Only in this case it seems to be Leviton Decora with four preset time intervals. It also has to be ten times compatible, right? Well, It would take some thorough checking before I am finished with this. However, I give you my word son!
