Xiaomi’s smart scales are not just a weight measurement tool, but a full-fledged analytical tool that helps track body composition, fat, muscle mass, and even bone density. But all of these data are really useful only after synchronization with the mobile app. Mi Fit was used for this, but now its functionality is transferred to Zepp Life (formerly Amazfit), which has become a universal hub for all the gadgets of the Xiaomi and Amazfit ecosystem.
Many users have difficulty connecting for the first time: the scales are not in place, the data is not synchronized, or the application gives an error. In this article, we will discuss all possible ways of connecting, including solving typical problems, and give recommendations for setting up accurate measurements. We will pay special attention to the Mi Body Composition Scale 2 and Xiaomi Smart Scale 2 models, but the instructions will also fit for other versions.
If you've just unpacked the scales and want to set them up quickly, go straight to the step-by-step section. If you've already had problems synchronizing, look at the block with the errors and their solutions.
