Automatic Wall Switch Timer, a device that effortlessly turns lights and ceiling fans on & off. Saving energy and money. We use this for our front door light, every night it turns on the light, and every day it turns it off. You can set the timer either daily, weekly or multiple day program options. It has an LCD display with quartz clock accuracy and room temperature reading on screen. It operates with 2 AA batteries. It does make a “robotic” noise when it functions, but you will get used to the sound. For nights when we are out of town, It gives an impression that we are at home which wards off suspicious people. I highly recommend this device. You can buy it at Amazon. Just click on the widget above and it will take you directly to the item page.
