Regarding this issue, Huawei Sports Health and Xiaomi Watch can be connected, but you need to install Huawei Sports Health app on Xiaomi Watch and Bluetooth pairing between the two devices. Please note that some functions may not work properly because Huawei Sports Health and Xiaomi Watch are different brands of products.
Surely not! Their own brand of hardware must be docking their own APP. Xiaomi Watch docking APP is Xiaomi wear.
