Hello Aqara doorbell users! I’m having a problem with my newly purchased G401 doorbell. I tried connecting it to the Aqara app but encountered the following issue. When I turn on the devices, the doorbell appears in the app. When I select it, I have to scan the device. There are two codes on the doorbell, and the app says “incorrect QR code.” I also scanned the hub code, but it’s picked up but displays “Bluetooth disconnected.” This is my second doorbell in three days. I thought the first one was broken, but I had the same result as the first one. I hope you have a solution. I’ve installed three doorbells myself but never experienced this kind of problem. Thanks in advance for your tips!

@sale0299 Hello! Sorry to hear you’re having trouble with your G401 doorbell. Let’s try to troubleshoot based on common setup issues:
First, when scanning the QR code, ensure you’re using the correct one for the Aqara app (not the HomeKit code). If the app still says “incorrect QR code,” check if your Aqara Home app is up to date, as outdated versions might cause scanning issues.
For the “Bluetooth disconnected” error, make sure your phone’s Bluetooth is enabled and move closer to the doorbell and hub during setup—distance can interfere with Bluetooth connections. Additionally, the Chime Repeater (if used) only supports 2.4 GHz Wi-Fi; if your network is 5 GHz, switch to 2.4 GHz and ensure the Wi-Fi name/password has no special characters, as these can cause connection failures. Also, check if your router has “Wi-Fi anti-squatter” or “AP isolation” enabled—disabling these might help .
If the issue persists, try resetting the doorbell to factory settings (hold the reset button for 10 seconds) and restarting your router before attempting setup again.

@sale0299 Hello! Sorry to hear you’re having trouble setting up your G401 doorbell. Let’s try to troubleshoot this step by step.
First, ensure the Aqara Home app is up to date, as outdated versions can cause pairing issues . For the “incorrect QR code” problem, if the doorbell was previously added (even accidentally) or linked to HomeKit, it might interfere. Try removing it from HomeKit first (if applicable) by opening the Apple Home app, finding the doorbell, and selecting “Remove Accessory” . Then, reset the doorbell to factory settings (usually by holding the reset button) and attempt pairing again.
For the “Bluetooth disconnected” error, make sure the doorbell is in pairing mode and keep the hub close to the doorbell during setup . Also, check that your phone’s Bluetooth is enabled and try restarting your phone to refresh the connection. If the issue persists, ensure all devices are on the same Wi-Fi network and restart your router .
Since this is a new device, it’s less likely to be a hardware issue, but these steps often resolve pairing glitches. Let us know if you try them—we’re here to help!
If you still face problems, feel free to share more details, and the community can chime in. For further assistance, you can also contact customer service through the Aqara Home App (Profile>Help&Feedback>Customer Service).

@sale0299 I’m sorry to hear you’re struggling with binding your new G401 doorbell—dealing with the same issue on a second device must be really frustrating! From the reference information available, there isn’t specific troubleshooting for the “incorrect QR code” or “Bluetooth disconnected” errors during setup. If any community members have faced similar problems and found solutions, sharing your experience would be incredibly helpful for others!
