How to connect Xiaomi scales to Redmi phone: a step-by-step guide

Integrating Xiaomi ecosystem devices into a single network allows you to create a truly smart home where all gadgets work in concert.Smart scales are one of the most popular health-tracking accessories, but their initial setup on Redmi smartphones can raise questions for beginners.

Redmi phone owners often encounter features of the MIUI or HyperOS shell that aggressively control background processes to save energy, which can prevent the stable transfer of weight and body composition data to the cloud. Understanding the principles of the BLE (Bluetooth Low Energy) protocol and the correct sequence of actions will help avoid common errors in the first run.

In this article, we’ll take a look at all the nuances of connectivity, from choosing the right app to solving complex sync problems. You’ll learn why Mi Fit may not see the device and how to properly configure permissions for stable operation. It’s critical to use the Zepp Life app (formerly Mi Fit) for basic setup, as the standard Health app on Redmi often doesn’t have any weight drivers.

Preparation of equipment and selection of applications

Before starting the procedure, make sure your equipment is ready to go.Smart scale Xiaomi Mi Body Composition Scale 2 or the newer model Mi Scale 2 requires the presence of serviceable AAA batteries. Even if the device is new, it is recommended to check the charge, as long-term storage could discharge the batteries.

Redmi should have Bluetooth enabled and active geolocation, a requirement that often surprises users, but is dictated by Android OS security policies that equate finding Bluetooth devices with location scanning.

The key is the choice of software, and although Redmi phones pre-installed the Mi Fitness app (formerly Xiaomi Wear), it's not always a good fit for scales, and historically, the most stable work comes from the Zepp Life app (formerly Mi Fit), which we'll see as the primary pairing tool.

💡

For maximum compatibility, download apps only from the official Google Play store or GetApps, avoiding third-party builds that may contain bugs in Bluetooth drivers.

Make sure your device has the latest version of the operating system installed. Older versions of Android may not properly handle data packets from newer versions of the scales. Check for updates in Settings → About Phone → MIUI version.

Step-by-step instructions for pairing devices

The connection process requires a strict sequence of actions. First, you need to prepare the software environment on a Redmi smartphone. Install the Zepp Life application from the app store and launch it. You will need to create a Mi Account or log in to an existing one.

Once you log in, go to the user profile. At the top of the screen or in the settings menu, find the add button for a new device. QR-Select the option "Add device" and in the list find Mi Body Composition Scale 2.

Now, we're going to physically interact with the scales. Stand on the platform with one foot to light up the Bluetooth indicator. Don't get up with two legs at once if the scales aren't already paired, because they can go into weighing mode without detection. Once the phone detects the device, click on it in the list to start the pairing process.

Once the scales are successfully connected, they may suggest updating the firmware. The firmware update is an important step in correcting calibration errors and improving the accuracy of fat measurements. Don't interrupt this process and keep the phone near the scales until it's complete.

Configure permissions in MIUI and HyperOS

The MIUI and HyperOS shells on Redmi smartphones are known for their strict energy-saving policies, which means the system can kill the Zepp Life app process as soon as you remove it from the screen, resulting in loss of weight data.

To prevent this, you need to configure autorun and permissions. Go to Settings → Apps → All apps, find Zepp Life (or Mi Fit). In the Permissions menu, make sure that access to location, Bluetooth and phone is allowed all the time, not just when you use.

Pay special attention to the activity control section, where you select the "No Limits" option, which allows the application to constantly search for scales in the background and synchronize data immediately after weighing, without which you will have to manually open the application every time.

⚠️ Note: If you use Flight mode or battery saving, data synchronization with weights will not occur. Adding an app to eliminate energy savings is a must for the smart home to function properly.

Also check your Bluetooth settings. Some versions of Redmi's firmware have a feature called "Show Connection Notifications." Turn it off for the scales so that the phone screen doesn't light up every time you just walk past the device. This is done on the paired device menu by tapping a gear next to the scale name.

Comparison of Weight Management Applications

Users often wonder which app is best for data analysis. In addition to the standard Zepp Life, there are alternatives like Mi Fitness and third-party utilities like Notify for Mi Fit. Each program has its own interface features and depth of analysis.

Zepp Life remains the “gold standard” thanks to detailed statistics and support for all Xiaomi scale models. Mi Fitness offers a more modern but simplified interface that may not display some specific parameters, such as protein levels or visceral fat, depending on the regional version.

Third-party apps often act as a bridge, transferring data from the Xiaomi ecosystem to Google Fit or Apple Health. This is convenient if you use a mixed fleet of devices. However, the native app always provides the most accurate calibration and quick updates.

Below is a table comparing the functionality of the main Xiaomi weights apps on Redmi devices:

If you want to know more about your deep analytics and your history of fat and muscle mass, stay with Zepp Life. If you’re building a single ecosystem with the new Xiaomi Watch S3, you might want to make the switch to Mi Fitness.

Data Interpretation and Health Metrics

Once connected, the scales transmit a wide range of data. In addition to your normal weight, the Mi Body Composition Scale 2 measures impedance to calculate your body composition, and understanding these metrics will help you manage your health more effectively.

BMI is a baseline measure based on height and weight, but it doesn't differentiate between muscle mass and fat mass. So athletes with high muscle mass can have high BMI, which is not an indicator of obesity. Xiaomi scales take this into account, providing a more detailed picture.

One of the key parameters is fat percentage, measured by bioimpedance analysis, and for accurate results, we recommend that you take an empty stomach in the morning, immediately after you wake up and go to the toilet, and at this time, your body's water balance is most stable.

💡

To track real progress, pay attention to the dynamics of changes over the course of the month, rather than to the one-time weight loss that can be caused by fluid retention in the body.

Also, Metabolic Age, which shows how much your metabolism matches your passport age group, and the decrease in this rate during exercise is a great motivating factor, indicating an increase in muscle mass and fat burning.

Solving common problems and errors

Despite the simplicity of the technology, Redmi users may face difficulties. A common problem is that the scales are visible in Bluetooth but not connected in the app. In this case, cleaning the Bluetooth cache will help. Go to Settings → Apps → Show all applications → System → Bluetooth and click Clear Data.

Another error is "Device is busy." This happens if the scales were previously paired with another phone or tablet. Xiaomi scales can only store one active connection in real-time data transfer memory. You need to turn off Bluetooth on all other devices within a 10-meter radius.

⚠️ Note: Do not try to connect scales via the standard Bluetooth menu in Android settings as an audio device or headset.Pair must occur strictly within the Zepp Life or Mi Fit application, otherwise data transfer will not work.

If the data stopped syncing after updating the phone’s firmware, try removing the device from the app and adding it again.Be sure to remove the batteries from the scales for 30 seconds before completely resetting the communication module.This action often solves problems with the “hang” of the Bluetooth stack.

In rare cases, the problem lies in the Mi Account itself: If servers are overloaded or there is a sync error on the cloud side, the data may not be saved, check the status of the servers or try to log in from another device for verification.
