Lutron’s DIY Caséta line has come a long way since launching in 2014 with a just singular in-wall dimmer and a plug-in lamp dimmer. Caséta was the first smart lighting product to make professional-level lighting control available to anyone with a screwdriver. Now, with a wide range of smart dimmers, switches, and plugs for indoors and out, Caséta offers a complete smart lighting control system that is also easy to use. It’s pretty easy to install and works reliably, and its many integrations with other products will completely change the way you view lighting. But what is the Caséta Smart Hub and how do you know when you need one? Read on to learn the features of the different Caséta Smart Hubs and when you would want to add one to your system.
