Your dimmer works with

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.

What to do if...

When power is applied, the light turns on but the dimmer is not able to change the light level:

For proper operation the dimmer needs a line (hot), neutral, load, and ground connection.
Confirm the white conductor is a neutral.
If using LED or CFL bulbs, make sure they are dimmable.

The dimmer does not dim low enough or begins to flicker at the low end of the dimming range:

Use the My Leviton app to increase the minimum dim level to the point that does not cause the LED bulb to flicker.

Intermittent dimmer operation:

Confirm the load does not exceed its ratings.

Not connected to Wi-Fi:

If your device is setup in the My Leviton app, select your device, then select "Device Settings". On the "Device Settings" screen, select "Reconfigure Wireless".
Follow the prompts to reconfigure your device and update the Wi-Fi settings.

How do I clean my device?

To clean use a damp cloth with mild soap. DO NOT use disinfecting products, including foggers, sprays or other types of atomized cleaning agents.
