When power is applied, the manual buttons do not control the
lights and the lights do not turn ON when motion is present:
• Verify that the wiring connections are secure.
• For proper operation, the Motion Dimmer needs a Line (Hot),
Neutral, Load, and Ground connection.
When power is applied, the light turns ON, but Motion
Dimmer is not able to change the light level:
• Confirm that the white conductor is a Neutral.
• If using LED or CFL bulbs, make sure they are dimmable.
Motion 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 it does not cause the LED bulb to flicker.
Lights do not turn ON when motion is detected:
•
Motion may be beyond sensing range - move closer to device.
• Go to Motion Sensor Calibration in the My Leviton app to
increase the sensor sensitivity and coverage area, or adjust
the ambient light settings.
• Make sure you are in Occupancy mode.
Lights always stay ON:
• Check app settings for how long the Motion Dimmer waits
before turning the lights OFF after no motion is detected.
• Check that Dimmer is not installed near a heat source or
detecting motion from an adjacent area (e.g., hallway traffic)
• Make sure you are in Occupancy mode.
Intermittent dimmer operation:
• Confirm that the Load does not exceed its ratings.
Not connected to Wi-Fi:
• If your device is set up in the My Leviton app, select your
device, and then select “Device Settings“. On the “Device
Settings” screen, select “Reconfigure Wireless“. Follow
prompts to reconfigure device and update Wi-Fi settings.
How do I clean my device?

When power is applied, the manual buttons do not control the
lights and the lights do not turn ON when motion is present:
• Verify that the wiring connections are secure.
• For proper operation, the Motion Dimmer needs a Line (Hot),
Neutral, Load, and Ground connection.
When power is applied, the light turns ON, but Motion
Dimmer is not able to change the light level:
• Confirm that the white conductor is a Neutral.
• If using LED or CFL bulbs, make sure they are dimmable.
Motion 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 it does not cause the LED bulb to flicker.
Lights do not turn ON when motion is detected:
•
Motion may be beyond sensing range - move closer to device.
• Go to Motion Sensor Calibration in the My Leviton app to
increase the sensor sensitivity and coverage area, or adjust
the ambient light settings.
• Make sure you are in Occupancy mode.
Lights always stay ON:
• Check app settings for how long the Motion Dimmer waits
before turning the lights OFF after no motion is detected.
• Check that Dimmer is not installed near a heat source or
detecting motion from an adjacent area (e.g., hallway traffic)
• Make sure you are in Occupancy mode.
Intermittent dimmer operation:
• Confirm that the Load does not exceed its ratings.
Not connected to Wi-Fi:

When power is applied, the manual buttons do not control the
lights and the lights do not turn ON when motion is present:
• Verify that the wiring connections are secure.
• For proper operation, the Motion Dimmer needs a Line (Hot),
Neutral, Load, and Ground connection.
When power is applied, the light turns ON, but Motion
Dimmer is not able to change the light level:
• Confirm that the white conductor is a Neutral.
• If using LED or CFL bulbs, make sure they are dimmable.
Motion 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 it does not cause the LED bulb to flicker.
Lights do not turn ON when motion is detected:
•
Motion may be beyond sensing range - move closer to device.
• Go to Motion Sensor Calibration in the My Leviton app to
increase the sensor sensitivity and coverage area, or adjust
the ambient light settings.
• Make sure you are in Occupancy mode.
Lights always stay ON:
• Check app settings for how long the Motion Dimmer waits
before turning the lights OFF after no motion is detected.
• Check that Dimmer is not installed near a heat source or
detecting motion from an adjacent area (e.g., hallway traffic)
• Make sure you are in Occupancy mode.
Intermittent dimmer operation:
• Confirm that the Load does not exceed its ratings.
Not connected to Wi-Fi:
• If your device is set up in the My Leviton app, select your
device, and then select “Device Settings“. On the “Device
Settings” screen, select “Reconfigure Wireless“. Follow
prompts to reconfigure device and update Wi-Fi settings.

When power is applied, the manual buttons do not control the
lights and the lights do not turn ON when motion is present:
• Verify that the wiring connections are secure.
• For proper operation, the Motion Dimmer needs a Line (Hot),
Neutral, Load, and Ground connection.
When power is applied, the light turns ON, but Motion
Dimmer is not able to change the light level:
• Confirm that the white conductor is a Neutral.
• If using LED or CFL bulbs, make sure they are dimmable.
Motion 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 it does not cause the LED bulb to flicker.
Lights do not turn ON when motion is detected:
•
Motion may be beyond sensing range - move closer to device.
• Go to Motion Sensor Calibration in the My Leviton app to
increase the sensor sensitivity and coverage area, or adjust
the ambient light settings.
• Make sure you are in Occupancy mode.
Lights always stay ON:
• Check app settings for how long the Motion Dimmer waits
before turning the lights OFF after no motion is detected.
• Check that Dimmer is not installed near a heat source or
detecting motion from an adjacent area (e.g., hallway traffic)
• Make sure you are in Occupancy mode.
Intermittent dimmer operation:
• Confirm that the Load does not exceed its ratings.
Not connected to Wi-Fi:
• If your device is set up in the My Leviton app, select your
device, and then select “Device Settings“. On the “Device
Settings” screen, select “Reconfigure Wireless“. Follow
