Maintenance
The Philips Wiz Connected A21 Smart Wi-Fi LED Bulb requires minimal maintenance. To ensure optimal performance and longevity:

Troubleshooting
If you encounter issues with your smart bulb, refer to the following common troubleshooting steps:
- Bulb Not Responding: Ensure the light fixture switch is in the ON position. Check your Wi-Fi connection and ensure the bulb is within range of your router.
- Connectivity Issues: If the bulb frequently drops from the network, try power cycling the bulb (turn off and on at the switch). Ensure your Wi-Fi router is broadcasting a 2.4 GHz signal, as the bulb is not compatible with 5 GHz networks. Move the bulb closer to the router if possible.
- App Not Detecting Bulb: Verify that your smartphone is connected to the same 2.4 GHz Wi-Fi network as the bulb during setup. Restart the WiZ app and try the pairing process again.
- Voice Control Not Working: Confirm that your WiZ account is correctly linked to your voice assistant app (Alexa, Google Home, Siri Shortcuts). Check your internet connection and ensure your voice assistant device is online.
- Bulb Not Turning Off Completely: Some fixtures or wiring may cause a slight glow even when off. If this occurs, ensure the bulb is fully compatible with your fixture.
