Agreed. General sports health apps and smart watches have a certain degree of versatility, millet sports can be connected to Huawei watch, but because millet and Huawei are two different brands, the user experience is slightly worse. Open Xiaomi Sports, click My in the lower right corner of the home page, find the device after entering, click Add device after entering, Xiaomi sports can search for Huawei watch to complete the matching connection.
This is not possible, each brand of products, there is a separate APP to connect, Xiaomi is Xiaomi sports, Huawei is Huawei sports health
