I've only recently discovered the Caseta line of products, but have been a happy Lutron customer for years. I love the Caseta concept and how it is geared towards less tech savvy customers. The limited selection of devices though is very frustrating.
I currently run the Maestro line of fan/dimmer canopy modules/switches in all my rooms with ceiling fans. Love them but why don't we have a Caseta RF version? There is a Maestro IR version, but why can't we get an RF version.
Also it seems that there are quite a few of the RadioRA2 RF devices that can be used locally with Caseta in wall switches, dimmers and lamp modules but they cannot be integrated into the Caseta smartbridge. Obviously they are compatible from a hardware perspective because they operate the Caseta devices but the front end apps and Smartbridge firmware don't support them.
The only reason I can think of for the lack of integration between Caseta and RadioRA2 is to protect the high end marketing of the RadioRA2. I get it, but it's frustrating none-the-less.
