Yasorn (the seller), has a variety of these relay switches. Some are wireless rf & some are "Smart" switches that connect via WIFI to Alexa & other smart home universes. Yasorn calls their wireless switches with remotes "Smart", which led me to order the wrong one. I can't return it.They also have 12v & 110v versions. In haste, I chose 110v when I needed 12v. So I have 2 I don't need. The one I need--12v Smart (Alexa capable)--has a delivery date well into December. So I'm 0 for 2 and trying a different brand. As far as I know, they work fine. They're the best looking of the lot & include the new-style connector for free. A nice touch. But if you order wrong as I did, it's an expensive way to get 2 connectors.
