7. Troubleshooting
- Lights Flickering at Low Brightness:
If your bulbs flicker at the lowest brightness settings, adjust the "Brightness Range" in the GHome app. Increase the minimum value (e.g., from 1% to 10% or higher) until flickering stops. For normal use without flickering, default the range to 1%-100%.

- Switch Not Connecting to Wi-Fi:
- Ensure your Wi-Fi network is 2.4GHz. The switch is not compatible with 5GHz networks.
- Verify your Wi-Fi password is correct.
- Move the switch closer to your Wi-Fi router during setup.
- Restart your router and try the pairing process again.
- Confirm the switch is in pairing mode (usually indicated by a rapidly blinking light).
- Voice Control Not Working:
- Ensure your GHome account is correctly linked to Amazon Alexa or Google Home.
- Check your internet connection.
- Verify the device name in the GHome app matches the name used in voice commands.
- Random On/Off Behavior:
- Check for any active schedules or timers in the GHome app that might be causing the behavior.
- Ensure no "Away Mode" or similar routines are enabled in your Alexa or Google Home app that could be triggering the switch.
- If the issue persists, try resetting the switch and re-pairing it.
- No Power to Switch:
- Check the circuit breaker to ensure power is on.
- Verify all wiring connections (Line, Load, Neutral, Ground) are secure and correct.
- Confirm a neutral wire is present and properly connected.
- Status After Power Failure:
The switch is designed to retain its last state (on/off/brightness) after a power outage, restoring to that state once power is re-established.
