Decora Smart Wi-Fi Dimmer makes
it easier than ever to control your
lights how you want. Use your
voice with Amazon Alexa, Google

to control lighting with the My
Leviton app, even when you’re
away from home.
The Decora Smart Wi-Fi Dimmer
looks right at home with your
other Decora
®
in-wall devices
and features intuitive on/off and
dim/bright control easily used by
anyone in the house.
Combine with other Decora Smart
Wi-Fi devices to create a whole
home experience with room
scenes, activities, and schedules
for connected lights to match
your lifestyle.
• Dimmable LED, dimmable CFL,
incandescent, and MLV lighting.
• Do not use your dimmer with metal
wall plates, electronic low voltage,
motor loads, or aluminum wire.
• When two or more dimmers are
installed next to each other, the load
ratings become 500W incandescent
and 500VA MLV for each dimmer.
No reduction is necessary if the load
is LED or CFL.
• For compatible LED bulbs, go to
leviton.com/LED.
• Additional self-service support
options can be found in the My Leviton
app or at leviton.com/decorasmart.

are required to operate this device.
Quick tip: Neutral wires are typically white and will be
found bundled inside the electrical box.

Things to consider:
To control the dimmer from more than one location such
as in a 3-way or multi-way, you will need either a wired
DD00R or DD0SR Companion device, or a wireless DAWDC
or DAWSC Anywhere Companion device. See Dimmer or
Switch Companion instructions for connection directions.
If your wall box looks different, call an electrician.
If your wall box contains a different wiring
configuration, contact Leviton’s technical support
team or consult an electrician.
WARNING: TO AVOID FIRE, SHOCK OR DEATH, turn off
power at the circuit breaker.
NOTE:
• Neutral connection is required.
• The YELLOW/RED traveler wire is only used in 3-way
applications; remember to put a wire connector on the
YELLOW/RED traveler even if not in use.
