Bests & Worsts Reviews from Amazon

Installed two programmable switches in 30mins. I am not an experienced electrician so I had to educate myself on what the various wires do. Hopefully this will save you some time. This switch requires three wires. The "Line" or Hot wire (usually black), the "Load" usually blue/red and Neutral (usually white). My old switch that controls porch light only had two wires installed, Line (Black) and Load (Red), but I found the Neutral (White) wire tucked behind. After connecting the Line and Load wires, the switch did not power on. So I reversed the Line and Load wires and it works. Programming is straight forward. I like the fact that I can have my porch light turn on at sunset and off at sunrise based on actual time of sunset which you enter latitude/longitude of your location. Basically set it and forget ti.
