6. Troubleshooting

Problem Possible Cause Solution
Doorbell goes offline / No live view The device is a low-power doorbell and enters hibernation when not in use. This is normal. The doorbell will wake up when the button is pressed or motion is detected. Ensure your APP notification settings are correct to receive alerts.
Cannot connect to WiFi Incorrect WiFi password, 5GHz WiFi network, or WiFi with special symbols. Ensure you are connecting to a 2.4GHz WiFi network. Verify the password. Reset the device and try pairing again.
No APP notifications APP permissions not granted, or phone settings blocking notifications. Check your mobile phone's APP notification settings and ensure all necessary permissions (message push, location, etc.) are granted to the Tuya Smart APP.
Chime not ringing Chime not paired with doorbell, or low battery. Follow the "Doorbell and Chime Matching" steps (Section 3.4) to re-pair. Ensure the chime is powered (USB powered).
Poor signal range Interference from metal objects (e.g., iron door) or distance from chime/router. Relocate the doorbell or chime to avoid metal obstructions. Ensure the doorbell is within the recommended range of your WiFi router and chime.
