• For proper operation, the switch needs a line (hot), neutral, load, and ground connection.
• Confirm the white conductor is neutral.

My lights work but they are flickering:

• Unscrew the light bulb and test with a voltage tester to make sure a line (hot) and neutral wire are connected to the light. Not connected to Wi-Fi:
• If your device is set up 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.
