With Caseta, the first Lamp Dimmer you add to the system will function as a repeater. Otherwise, there are no auxiliary repeaters. If you have an existing install with several Lamp Dimmers, unpair and repair them, and be sure to place the first one in the most appropriate Lamp Dimmer location to extend the range or cover a dead spot.
The lack of aux repeaters is an intentional shortcoming with Caseta. This alone is why Ra2Select is a worthwhile product offering.
Ra2Select can be programmed from an iPad (like Caseta). Dealers wanted that....
Ra2Select can be upgraded to full blown Level-2, 200 device, Ra2 job by simply swapping one device (the main repeater). That alone is another giant selling point to Ra2Select.
Same goes with the applications where their design grows to include power bposters or other devices that only exist on full blown Ra2. With Caseta installed in the first instance, you would be having a very uncomfortable conversation about replacing every single device.
However, if you are already planning to rip out Caseta and go to C4 whenever the Caseta device limits are reached, then your situation is atypical. It is not at all in Lutron's interest to specifically suit to your plans, and your own mileage may vary.
For Lutron to support a low cost product to a full-blown 200 limit Ra2 Lutron upgrade path in in everyone else's interest.
