Although I have Samsung SmartThings (highly recommended), I still have a couple of X10 switches that I don't use that often that I want to replace with ZWave. This device (plus the X10 receiver I already had, about $19) and the help of YouTube allows me to control these switches with Google Home, Alexa, or SmartThings. This receiver is connected to a Win 10 Virtual PC running on my MacBook Pro.
