Installation Steps
Turn Off Power and Remove Old Switch
For your safety, go to your circuit breaker and turn off the power to the switch you are replacing. Confirm the power is off by flipping the switch. Then, remove the wallplate and unscrew the old switch from the wall box. Carefully pull it out to expose the wiring.
Disconnect and Connect Wires
Disconnect the wires from the old switch. For the new Caseta dimmer, connect the green ground wire to the bare copper or green wire in the box. Connect the two black wires on the dimmer to the remaining two wires from the wall (hot and load). It does not matter which is which.

Gently push the wired dimmer back into the electrical box. Use the provided screws to secure the dimmer to the box. Once it is securely in place, you can attach the Lutron wallplate, which snaps on for a clean, screwless look.
Power On and Pair
Turn the power back on at the circuit breaker. The dimmer's LED indicator should light up. Test the switch manually. To add smart control, pair it with a Pico remote by holding the remote close and pressing and holding the 'off' button on the dimmer for 6 seconds.
