I installed my first "smart" switch in 2010. It was a Leviton Z-Wave switch. Back then, getting automated "smart home" stuff was expensive, hard, and complicated. I was forced to do this as a result of some wacky wiring in my kitchen that required I have a smart keypad that can turn two lights on at once. The Leviton Viza RF+ products did the job for a number of years. But programming Z-Wave products stinks and interoperability is not perfect.
