How To Fix Eufy Doorbell QR Code Not Working?

When installing your Eufy doorbell, you will be prompted by the app to scan the QR code located on the back of the doorbell.

Simply use your tablet or smartphone’s camera and scan the QR code using the Eufy Security app, just like taking a photo.

However, some users have encountered difficulties during this step as their cameras were unable to scan the code on the device.

For users experiencing Eufy doorbell QR code problems, fret not. This article explores the primary causes and offers effective solutions.

Why is my Eufy Doorbell QR Code Not Working?

Possible reasons for your Eufy doorbell QR code not functioning properly:

1. Bad Lighting Conditions

Insufficient lighting is a key factor causing your doorbell’s QR code to fail. It is crucial to ensure that the entire environment is adequately illuminated before attempting to scan the QR code. Without proper lighting, you will not be able to unlock the doorbell.

2. Bad Camera Resolution

Insufficient camera resolution can hinder QR code scanning by failing to capture necessary details

3. When Your Phone is too Far from your Doorbell

Ensure a successful scan of your QR code by managing the distance between your doorbell and phone. Avoid being too far away, but also ensure you are not too close. Maintain a considerable distance of 3 to 5 meters between the lens and the QR code for smooth scanning.

4. Damage or Dirty Camera Lens

A camera lens that is dirty or damaged can significantly impact the quality of the images captured by the camera. This can cause difficulties when attempting to scan a QR code.

5. Improper Phone Alignment

The positioning of your phone greatly affects its ability to scan QR codes. When the phone is not aligned correctly, scanning the QR code becomes challenging and unsuccessful. Invest in optimal positioning for seamless scanning.

6. QR Code Printing Problems

When it comes to QR codes, precision is key. If these codes are not printed correctly or appear on subpar surfaces, they may lack the clarity necessary for camera scanning. Uncover the importance of pristine printing for optimal QR code functionality.

7. Software Glitches

If your Eufy doorbell is struggling to scan QR codes, it might be due to software glitches. In such cases, a firmware update or factory reset could be the solution you need.

To get to the bottom of why the QR code isn’t functioning properly, it’s crucial to consider these factors. Identifying the root cause is key to finding the right fix for your Eufy doorbell.

How To Fix The Eufy Doorbell QR Code Not Working?

Learn how to quickly fix the issue of your Eufy Doorbell QR Code not working by following this easy-to-follow guide.

1. Check the Lighting

To improve the functionality of a QR code that isn’t working properly, start by adjusting the lighting in the environment. If the lighting is too dim, increase it to minimize the impact of the screen’s brightness on the code’s readability.

Alternatively, if the room is too bright, make adjustments by lowering the brightness level. If you have smart bulbs, you can simply instruct virtual assistants like Alexa or Siri to reduce the brightness by 50 percent.

2. Adjust the Camera Angle

To capture the QR code completely, make sure the camera is positioned at the right height and angle. If needed, adjust the camera angle or bring it closer to the QR code.

3. Reduce the Distance Between Your Phone and the Code

To address the issue of your QR code not working, try reducing the distance between your phone and the code. Certain phones are not optimized for long-range scanning, so bringing the phone closer to the code is the most effective solution for a malfunctioning doorbell QR code.

Additionally, if your phone lens is too close to the code, successful scanning can become challenging. In such cases, you must increase the distance between your phone and the code. Aim to keep your phone within 5 to 7 meters from the barcode when attempting a scan.

4. Checking the Lens

If you’re having trouble scanning QR codes, the issue might not be with the code itself, but rather with the condition of the lens. To solve this problem, start by checking the lens for any issues.

If the lens is dirty or damaged, it may prevent you from scanning codes effectively. Use a microfiber cloth to clean the lens and then try scanning again.

Remember, it’s important to remove any scratches or debris from the lens in order to eliminate this error. Taking care of the lens should address most issues you encounter while using it.

5. Clearing the Eufy Doorbell Code

The QR barcode must be accurately scanned by the Eufy Security app to access the data stored within it.

Ensure the code on the back of the Eufy doorbell is clear and free of dirt that could hinder scanning.

If the code appears clean, continue troubleshooting with other solutions.

6. Using Your Camera’s Flashlight

When scanning a QR barcode in a dimly lit room, the lack of light may hinder your camera’s ability to recognize the code. To overcome this issue, it is recommended to activate the camera flashlight.

By utilizing the flash’s light, you can effectively compensate for the insufficient illumination during low-light scenarios, such as indoor or nighttime settings.

This solution proves particularly useful when the darkness of the room is the primary obstacle preventing your camera from scanning the QR barcode.

7. Reset Your Eufy Doorbell

In case of any difficulties, consider performing a factory reset on the Eufy doorbell. This will restore the device to its original settings and potentially resolve any software problems you may be experiencing.
Learn how to easily factory reset your Eufy doorbell in just a few simple steps:

  • Ensure that your doorbell is powered On.
  • Locate the reset button at the back of the device.
  • Press and hold this button for a duration of 10-12 seconds.
  • Wait until a yellow light appears on the doorbell, indicating that the resetting process is in progress.
  • Allow the doorbell 30 seconds to complete the resetting process.

By following these straightforward instructions, you can quickly and effectively reset your Eufy doorbell.

8. Using a Different Mobile Device

Consider using a different mobile device as the next step. By switching to a different unit, you can adapt to the lighting conditions more effectively.

While it may be frustrating, there are limited options available. If you’re unable to successfully complete the scan with your current device, it’s worth trying a new one.

The goal here is to narrow down the problem to either the mobile device or the QR code itself.

If you’ve exhausted all other methods and the error persists, attempting a different device is a reasonable course of action.

With luck, the issue will be resolved when you test the new device. This will confirm that the problem lies with your current unit and not with the smart device itself.
