I briefly looked at it.
Looks like it can do the same stuff. I wouldn’t spend the money. The GUI is obviously different.
Maybe make a post on reddit with somebody that has a lot more hands on with both.
One thing regarding HomeKit. I’m not sure it uses the Lutron telnet connection to turn lights on or off for Lutron Caseta. It may reach out to the cloud ?
Also, I don’t see any options to dim over a course of time.
