Connecting my Smart Lock U100

I have installed my Smart Lock U100 and installed the app. When I try to do the set up in the app, it says it can not read the QR code. I see in other posts that is recommended to check the firmware updates and network settings, but you can only do that AFTER you have successfully added the smart lock to the app. Please do not send me your generic response, I need help please.

@stacyhoman Thank you for sharing the details of your experience—let’s see how we can get your Smart Lock U100 connected.

When the app cannot read the QR code, here are some steps to try based on Aqara’s guidance:

  1. Manual Addition:
    Instead of scanning the QR code, you can often select “Add Device” in the Aqara Home app manually. Tap the “+” in the upper right corner, choose “Smart Lock U100” from the device list, and follow the on-screen instructions. Sometimes, the app allows you to proceed by selecting your model directly.

  2. Check the QR Code:
    Make sure the QR code isn’t smudged or damaged. Clean the surface gently if needed, and ensure there’s enough light when scanning.

  3. Try Another Device:
    If possible, try scanning with a different phone or tablet to rule out camera issues.

  4. App Version:
    Double-check that your Aqara Home app is updated to the latest version from the App Store or Google Play.

  5. Alternative Setup Methods:
    If you’re still stuck, you might try connecting the lock to the Apple Home app first (if you use iOS)—this sometimes helps bypass QR code scanning issues, but note that some unique features (like fingerprint recognition and auto-lock) are only available via Aqara Home.

If you’ve tried all these and are still unable to proceed, this might indicate an issue with the QR code itself or a technical glitch. In that case, please contact Customer Service Team by Aqara Home App (Profile>Help&Feedback>Customer Service) or scanning the QR code:

, which will be efficient; If no Aqara Home account, direct to “Please click here” to create a ticket.

Let us know if any of these steps help, or if you find a solution—your feedback may help others in the community too!

@Naomi Absolutely right—thanks for sharing this tip! For the Aqara Smart Door Lock U100, scanning the QR code is not strictly required during the initial connection process with the Aqara Home app. Here’s how you can proceed:

  • Open the Aqara Home app.
  • Tap the “+” button in the upper right corner to enter “Add the device.”
  • Select “Smart Lock U100” from the device list and follow the in-app instructions for installation—no QR code scanning needed.
