4. Troubleshooting
If you encounter issues with your Linkind Smart Edison Bulbs, refer to the following common solutions:
4.1 Connectivity Issues

- Voice control not working: Verify that your AiDot account is correctly linked to your Alexa or Google Home app. Ensure your voice assistant device is online and within range.
4.2 Performance Issues
- Bulb flickering: These bulbs are not compatible with traditional dimmer switches. Ensure they are installed in a non-dimmable fixture or that any existing dimmer switch is set to full power (100%) or bypassed.
- Incorrect brightness or color temperature: Use the AiDot APP or remote control to adjust settings. If using voice control, specify the desired brightness percentage or color temperature (e.g., "warm white").
