You will need a Lutron Pico wall plate bracket if you'd like to mount a Pico smart remote control directly to a wall, for an additional point of control when using a Caseta Wireless dimmer. You'll also need a wall plate bracket if you're replacing existing switches in a 3-way application (where lights have 2 or more wall switches) with a Caseta Wireless In-wall dimmer and a Pico remote control. Pico remote control and wall plate sold separately.
