HomeKit Setup tips
– If you are setting up HomeKit device, please connect your smartphone or tablet to a 2.4 GHz Wi-Fi network and disable your VPN, if any. Ensure that your Wi-Fi is using WPA3/WPA2 since WPA3 only will lead to setup failure.
– Make sure your smart device is covered by strong Wi-Fi signal, which is not a hidden Wi-Fi name (SSID). A hidden Wi-Fi name (SSID) might not work when setting up.
– Meross HomeKit smart devices support iOS 13/ iPadOS 13 or later. It is recommended that you upgrade your iOS or iPadOS to the latest version before pairing with the smart device.(iOS only. Android users needs Android 6.0 or later)
– Upgrade the Meross app to the latest version and make sure you granted access permissions, such as location and local network, asked by the Meross app.
– Launch the Meross app and log in to your account, or if you are a new user, tap Sign up to create a new account.
– Relocation of the smart device does not require additional operations provided that it remains on the same network with strong Wi-Fi signal.
– If this is not the first time you’ve added this smart device, you’ll have to reset it before going any further.
– Deny Meross app to access Precise Loation and Local Network will lead to setup failure.
– If you have multiple Wi-Fi in your house, we recommend you to leave only one Wi-Fi on when you set up HomeKit. iPhone may connect to A Wi-Fi when initiating the HomeKit setup while end up with connecting to B Wi-Fi. The key is that this will lead to Homekit setup failure for sure since HomeKit requires iPhone to connect to the same Wi-Fi during the whole process.
