Frequently Asked Questions

Why does my Eufy doorbell firmware update keep failing?
Firmware updates typically fail due to weak Wi-Fi signals, low battery levels, or temporary server issues. Ensure your doorbell has a strong connection and sufficient power before attempting the update.
How long should a Eufy doorbell firmware update take?
Most Eufy doorbell firmware updates take 5-15 minutes to complete. The process should not be interrupted, and your phone should remain connected to Wi-Fi throughout the entire update.
Can I use my doorbell while a firmware update is in progress?
No, avoid using the doorbell or accessing it through the app during a firmware update. Interrupting the process can cause the update to fail and may require a factory reset.
What happens if I lose internet connection during a firmware update?
If internet connection is lost during an update, the process will fail and you'll need to restart it. The doorbell should still function normally, but you'll need to retry the update when your connection is stable.
How do I know if my Eufy doorbell firmware update was successful?
After a successful update, the app will show a completion message, and you can verify the new firmware version in the device settings. The doorbell will also function normally with any new features enabled.
