Xiaomi's smart scales are not just a weight measuring device, but a full-fledged body composition analyzer that transmits data to a smartphone via Bluetooth. However, many users face a problem: the scales are not detected by the phone, the connection is constantly reset, or the Bluetooth indicator does not light up at all. In 90% of cases, the problem lies not in the breakdown, but in the wrong activation of the module or synchronization errors.
In this article, we will discuss how to turn on Bluetooth on Xiaomi scales for all popular models (Mi Body Composition Scale 2, Smart Scale 2, Mi Scale, etc.), consider hidden settings that the manufacturer does not specify in the instructions, and give a checklist to eliminate typical errors.
If your scale suddenly stopped plugging in after you upgraded your firmware or changed your smartphone, here's the solution, and for those of you who've just unpacked your device, we've prepared a step-by-step guide with a photo of each step.
1.What Xiaomi scale models support Bluetooth?
Not all Xiaomi smart scales are equipped with a Bluetooth module - some budget models only transmit data over Wi-Fi or require a special hub. To avoid wasting time, check your model in the table below:
| Model of weights | Bluetooth support | Version of protocol | Compatible software |
|---|---|---|---|
| Mi Body Composition Scale 2 | β Yes (BLE 5.0) | Bluetooth Low Energy | Mi Fit, Zepp Life, Apple Health |
| Xiaomi Smart Scale 2 | β Yes (BLE 4.2) | Bluetooth Low Energy | Mi Fit, Google Fit |
| Mi Scale (1st generation) | β Yes (BLE 4.0) | Bluetooth Low Energy | Only Mi Fit (old version) |
| Xiaomi Mi Body Fat Scale | β Yes (BLE 5.0) | Bluetooth Low Energy | Mi Fit, Zepp Life |
| Xiaomi Mi Smart Scale Lite | β No (only Wi-Fi) | β | Requires Mi Home Hub |
If your model isnβt on the list, check the box or documentation β look for the Bluetooth SIG logo or a mention of BLE. Libras without Bluetooth are usually cheaper and have the word Lite in the name.
β οΈ Note: Xiaomi Mi Smart Scale Lite scales do not support direct connection to the phone. They need a Mi Home Hub (gateway) or a router with Mi Mesh support.
2.How to turn on Bluetooth on Xiaomi scales: basic instruction
In most Xiaomi models, the Bluetooth module is activated automatically when first turned on. However, if the scales have already been used or have been reset, manual activation may be required.

On touch-controlled models (such as the Mi Body Composition Scale 2), just touch the display to activate Bluetooth. If you don't establish a connection after this, go to the "Problem Solutions" section.
Install batteries with correct polarity|Put the scales on a flat surface|Check the battery charge (if there is an indicator)|Press the scale to activate the display|Wait for the Bluetooth icon to appear-->
Important: Xiaomi scales use the BLE (Bluetooth Low Energy) protocol, which consumes battery power economically. However, if the batteries are discharged below 20%, the Bluetooth module may not turn on. Replace the batteries if the indicator flashes red.

5. Problem Solving: Scales are not connected to the phone
If Bluetooth is on (the indicators are on), but the phone does not see them, use this checklist:

If the reset didnβt help, try an alternative way to connect:
- π² On Android: Enable Developer Mode β Turn on Bluetooth HCI Sniffer (can help with driver conflicts).
- π On iPhone: Go to Settings β Bluetooth, find the scales in the list and click Forget this device, then repeat pairing.
6.How to connect Xiaomi scales to multiple phones?
Officially, Xiaomi scales support synchronization with only one device via the Mi Fit.
Method 1: Using a single Mi Account
If both phones log in under the same Xiaomi account, the data will be synchronized automatically.
Method 2: Manual addition via Bluetooth
- On the first phone, turn off the scales in Mi Fit (but don't delete them!).
- On the second phone, turn on Bluetooth and find the scales in the list of available devices (the name will be type). MI_SCALE_XXXX).
- Connect manually (without Mi Fit).
- Run the Mi Fit on the second phone and add the scales as a new device.
Method 3: Export of data
In Mi Fit, you can export your measurement history to Google Fit or Apple Health, and then import it to another phone.
Mi Fit β Profile β Settings β Data Exportβ οΈ Note: When connecting scales to multiple phones, synchronization errors can occur at the same time. It is recommended to use one main phone for measurements, and on the second one, only view data through the cloud.
7.Alternative applications for connecting Xiaomi weights
If Mi Fit or Zepp Life is not suitable (for example, due to regional restrictions), you can use third-party applications:
| Annex | Support for models | Pluses | Cons |
|---|---|---|---|
| Sleep as Android | Mi Scale 1/2, Mi Body Composition Scale 2 | Integration with sleep trackers, export to Google Fit | Paid version for full functionality |
