For Lutron, you use an in-wall dimmer at one end of the circuit (the load end), and a remote at the other end. They're specific devices for the purpose. For RRa2, the only difference is that the actual switch has the LEDs on it, and the remote (RD-RD) does not. But same paddle controls. Similar for Caseta, but the remote end is an actual wireless Pico remote in a wall mount.
I just redid the switches in my stairwell, from the builder's hard-wired three way circuits to Lutron RRa2. I ended up adding a keypad at the bottom of the stairs and not using the three-way wiring at all. The original electricians ran both line and load to the boxes in the upstairs hallway, and ran just a pair of 14/3 to the downstairs boxes (one for each circuit). With the dimmers upstairs and a keypad (not a remote) at the bottom, those switch leg 14/3s are unused.
