# Lutron RA2 Select and RadioRA 3

*Lutron / 8 models*

> RA2 Select and RadioRA 3 are the Lutron systems above Caséta. Both use Clear Connect RF rather than Wi-Fi. RA2 Select is built around a main repeater. RadioRA 3 is a professionally installed system built around an all-in-one PoE processor, and it scales to 400 devices with paired processors. Lutron says both work with HomeKit, Alexa and Google Home. Home Assistant's lutron_caseta integration supports the RA2 Select Main Repeater and the RadioRA 3 processor.
