Maintenance
The WeMo Smart Light Switch is designed for minimal maintenance. To ensure optimal performance and longevity:
- Cleaning: Gently wipe the surface of the switch with a soft, dry cloth. Avoid using abrasive cleaners or solvents, as these may damage the finish.

Troubleshooting
If you encounter issues with your WeMo Smart Light Switch, try the following troubleshooting steps:

- Ensure the circuit breaker for the switch is in the ON position.

- If the issue persists, try resetting the switch to factory defaults (refer to the Quick Start Guide for specific instructions) and re-pairing it with the WeMo app.
- Voice Control Not Working:
- Ensure your WeMo switch is properly linked to your Amazon Alexa, Google Assistant, or Apple HomeKit account.
