- Ensure the user’s height and age data has been added and stored in the Yunmai App
- Ensure the plastic film is removed from the scale surface
- For accuracy, it is advised that the user being measured does not wear socks and their feet are placed firmly on the scales
- Ensure the user steps off the scales slowly and only once the progress bar on the display screen completes from left to right before flashing three times
There is no password needed to connect the scale. Install and log into the Yunmai App first and then turn on Bluetooth from your phone; it will connect to the scale automatically. If the password window pops up, simply click “cancel” and try it again. In some instances, you may need to manually pair it with the pass key “000000”. You may need to turn on location services on your phone and then switch your phone on and off again.
Often, this just means you are due to reinstall the App or change the Yunmai batteries if it is having difficulty connecting. You may also need to update your iOS or Android devices to the latest version from time to time in order to reinstall the Yunmai app.
Yes. The Yunmai App synchronises with the Apple Health, Ftibit and Google Fit Apps. Please turn on Connect to Apple Health/Google Fit/Fitbit in the Me—User settings. Fitbit will sync the latest data only if you fully exit (for iPhone, double click the start button and swipe with finger up) and then reopen it.
There are two ways to transfer data between the scale and smartphone. If your smartphone is close to the scale when you weigh yourself, the app will automatically connect with the scale through Bluetooth and will transfer the body metrics into the smartphone immediately.
The scale supports up to 16 user profiles. Each user can use their own smartphone or share one app and create profiles in Family Management. If users only have their individual profile in the app, the scale will only sync their data to their individual device. Users will not have access to each other’s data unless a user permits them to add their profile to their app. Users can use their personal smartphone and app/account to maintain privacy. If the scale already has 16 users and you wish to add one more, the app will remind you to delete an existing user profile.
Yunmai will ask for access on some Android devices, which is due to requirements from some Android platforms. Our technical team is working with Norton to remove these false warnings.
If you see the following warnings when installing Yunmai, please note that the information is only asked for the below reasons:
- Device and app history – only for write/read weight;
- Identity – to verify the account name and input height, age and basic information;
- Location – it is required by Android, Android 6.0 or later, which requires this access when you turn your Bluetooth on;
- Photo/Media/Files – to upload or take a profile picture;
- WiFi – to upload data to cloud.
If you have used other popular health management applications, such as MyFitnessPal, on Android, you may encounter the same thing. The access agreement is required by Android, however, iOS does not have this issue.
Yunmai app does not have access to any private information beyond measurements data stored in the app.
The scale might need to be re-calibrated in order to show accurate readings. To do this, please put the scale on a hard, flat surface like tiles. Step on and off the scale quickly; the scale will show 0.0kg – This indicates calibration has been completed.
Bluetooth connection is necessary to capture and record all data. Please ensure your device’s Bluetooth is switched on and then install the Yunmai App and log in. The Yunmai App should find the nearby scale and finish the registration automatically. Following this, step onto the scale with bare feet. The app should display “connected” at the top instead of “connecting” as well as all data. The scale should show the Bluetooth logo “B” along with weight.
The numbers you see on your scale may vary from professional medical instruments, which is normal. For reference, Yunmai is a home use scale.
Body composition analysis is an inexact science. Body fat scales are not as accurate when compared with professional medical instruments. This is true regardless of the manufacturer or method of measurement. The Yunmai scale uses BIA (bioelectric impedance analysis), which is a commonly used technology for estimating body composition, and in particular, body fat. BIA actually determines the electrical impedance, or opposition to the flow of an electric current through body tissues, which can then be used to calculate an estimate of total body water (TBW). TBW can be used to estimate lean body mass and by measuring the difference with body weight, body fat.
When you step onto the scale and align your feet to the sensors, an imperceptible low and safe electrical current passes up one leg across the pelvis, and then down the other leg. Because body fat contains much more water and muscle conducts electricity better than fat does, the greater the resistance, the more body fat you have. The scales use an algorithm to calculate a body-fat percentage from this resistance information, along with other data that you enter (height, weight, age, gender). Some also include hand electrodes to estimate overall body fat more accurately. Scales with only foot electrodes may underestimate body fat in users with lots of body fat and overestimate it in users with minimal body fat.
The most important thing with understanding body composition is to focus on the trends over weeks and months. The purpose of the Yunmai App is to assist you with health and fitness program by providing a periodic analysis.
Check that the batteries are installed correctly and/or trying changing the batteries to new ones.
The scale might need to be reactivated if changing the batteries does not solve the issue. To do this, turn on Bluetooth from your smartphone, open and log into the Yunmai app, and step on the scale with bare feet. The app should display “connected” on the top instead of “connecting…” as well as all data. The scale should show the Bluetooth logo “B” along with weight.
It is normal for the three indexes to add up to more than 100% since water is contained in fat and muscle.
The Yunmai scale includes four AAA batteries that are not rechargeable; these normally last three to six months depending on usage. Rechargeable batteries also work for Yunmai scales. The Yunmai 2 features a 3000mAH built-in Li-pro battery and USB Type-C cable for charging.
