If you can't pair HomeKit accessory with Apple Home app, here are all the solutions that you can refer to.

 

And we suggest you use the Meross app to set up and manage your HomeKit accessory.

 

First of all, please make sure that there is a HomeKit badge  on the package as shown in the first picture below. If  not, the accessory will not support HomeKit and won't have a HomeKit setup code. For switches, please tap "Don't Have a Code or Can't Scan" and input the setup code manually. The 8-digit code is on the label shown as the second picture below. For non-switch products, you can find the label shown as the third picture below on the product or user manual.

 

 

 

 

 

 

 

If your accessory has a HomeKit badge on its package and has a HomeKit setup code labeled, you can troubleshoot as follows. 

1. Check the information and set up as instructed.

    a. Your system is iOS 13, iPadOS 13, or later. If not, please upgrade it to the latest version.

    b. Make sure VPN / DSN services are disabled on your phone before adding devices. Meanwhile, Local Network and Location Services have to remain on in General -> Privacy for Home app on your iPhone or iPad. Otherwise, you might see error as shown below.

   

    c. Connect your iPhone or iPad to a 2.4GHz Wi-Fi network to add the accessory. The installation is going to fail with a 5GHz Wi-Fi network as shown below. If you are having a Mesh Wi-Fi system or having a unique Wi-Fi name for both 2.4GHz and 5GHz bands, in most cases, the router will allow you to finish the pairing. If the Home app fails to pair the accessory, as shown below, then please turn off the 5GHz Wi-Fi of your router temporarily until the accessory is successfully added. 

   

    d. Your accessory is powered on and placed close to the Wi-Fi router with a strong 2.4GHz Wi-Fi coverage.

    e. Reset the accessory in accordance with the user manual to get back to the configuration mode.

    f. If the QR code won't work, please tap "I Don't Have a Code or Cannot Scan" and input the 8-digit setup code manually.

    g. If the setup fails due to incorrect setup code as shown in picture 4, be sure to input the exact 8- digit code printed on the setup code label. And if it keeps saying incorrect setup code, please contact us at support@meross.com with the photo of your setup code label and a screenshot of picture 2. We will reply you with the right setup code as soon as possible.

   

   

2. If you fail in the very first step and the Home app shows "Could't add accessory". 

    a. Preserve the screen state and don’t switch to another app (stay the screen on and don't switch between apps) while the Home app is adding the accessory.

    b. Reset the accessory to get back to the configuration mode.

    c. If both steps are performed while the Home app still can't pair with the accessory, please reboot your iOS so that the Home app will clear its cache.

    These solutions should help you adress this failure. If not, please contact Meross Support for assistance.

   

3. The Home app shows "Uncertified Accessory". 

    This could be a glitch from cloud server of Apple. Please wait for 1~2 hours and retry again. Retry several time at different times of the day. Our customers have pointed this issue out and solved it here.

    This solution should help you pass this failure. If not, please contact Meross Support for assistance. 

   

4. If you go through all the steps above and the Home app shows the picture below. 

    a. Check whether the smart accessory lost power supply by chance. If yes, please try again after resetting the accessory and keep it powered on.

    b. Reboot your iOS so that the Home app will clear its cache. And then retry.

    c. Login to your Wi-Fi router to see whether it is running any MAC filtering or Access Control function. If yes, please turn it off since it will block your accessory from connecting to it. After you disable the MAC filtering or Access Control function, please retry.

    These solutions should help you address this failure. If not, please contact Meross Support for assistance.    

   

 

5. If you go through all the steps above and the Home app shows "No Response". 

    a. Check whether your accessories are powered off. If yes, please power them on and they will be back online.

    b. Power cycle your accessories and they will be back online.

    c. If you are out of your house and want to control the accessories remotely, you will have to set up a home hub. Please click here to learn more.

    d. Sometimes, Apple Home app cannot find local devices that are actually online, you can exit Home app and relaunch it. Or we suggest you use the Meross app to manage your accessories to avoid such issues.

   

6. If you can't set up the accessory with Apple Home app, please launch the Meross app and tap + at the top right when your iPhone or iPad is connected to your home Wi-Fi, and the Meross app will guide you through the pairing process. You will also be able to receive firmware update notifications in the Meross app and upgrade your accessories in Meross app once availabe.

7. If your router is Eero, please refer solution here.

 

If you lost the QR code or 8-digit setup code, please use an Android phone and launch the Meross app to retrive it back. Or, you can contact Meross Support with your Meross account and we will help you get it back.
