Xiaomi Smart Scale 2: How to Check Originality in 5 Minutes (with Photos and Codes)

Xiaomi Smart Scale 2 remains one of the most popular health gadgets due to its accuracy, integration with Mi Fit and affordable price. However, high demand has spawned a wave of fakes, from rough copies from AliExpress to “clones” that are seemingly indistinguishable from the original. According to Xiaomi Russia, up to 30% of weights in the secondary market and marketplaces are counterfeit, and their measurement error can reach ± 500 grams.

Counterfeiting not only distorts weight and body composition data, but also poses a safety risk: cheap lithium batteries in counterfeit devices are prone to overheating, and uncertified sensors can give false impedance readings (which is critical for people with pacemakers). In this article, we offer a step-by-step verification method based on Xiaomi’s official recommendations, service center reviews, and tests from independent laboratories (including Roskachestvo, QR-code, proprietary software and even hidden hardware tags that are silent sellers.

Important: Some methods (such as checking through Mi Home) require pre-binding the scales to the account — if the device is already activated by the previous owner, it will have to be reset.

1. Packaging check: 7 signs of forgery

The original Xiaomi Smart Scale 2 comes in a branded box with clearly printed security features. Counterfeit packages often give themselves away for trifles: blurry fonts, color mismatches or no holograms.

• 📦 Box material: original - matte cardboard with light texture, fakes are often glossy or too thin.
• 🔍 Barcode and QR: original codes are applied with laser printing (do not erase when rubbing), copies - the usual typographical paint.
• 🏷️ Serial number sticker: should be on the back of the box, with clear font and without spelling errors (e.g., "Made in Chine" instead of "China»).
• 🔗 Mi Home Link: The original box must indicate home.mi.com, fakes can link to third-party sites.

Pay special attention to the hologram on the top of the box: the original it changes color when tilted (the effect of “rainbow”), and when viewed from an angle, the Mi logo appears.

If the box is already open, check the package: the original must be scales, 4 AAA batteries (in some lots - 3), instructions in Chinese/English and a warranty card with the dealer's seal. Counterfeiting is often saved on batteries (invest 2 instead of 4) or replaced by a printout.

2.External inspection: details that give out a copy

Even if the packaging looks perfect, check out the scales themselves.The original Xiaomi Smart Scale 2 has a number of unique features:

• 🔳 Mi logo: on the original it is convex, with a glossy coating; for fakes - flat or matte.

Turn the scales over and look at the sensors: the original has 4 (in the corners) and they are covered with transparent silicone. Sensor fakes can have 2-3, and silicone often turns yellow or peels off. Also check the serial number on the bottom: it should match the number on the box and start with the letters LXM (for the Smart Scale 2 model).

Another reliable feature is the backlight of the display: the original screen lights up smoothly, with a soft white glow. For fakes, the backlight often flashes, has a blue/yellow hue, or turns on with a delay.

3. Check through the Mi Home/Fit app: step-by-step instructions

The most reliable way to detect a fake is to try to connect the scales to the official app, which is that counterfeit devices either don't connect at all or are defined as "unknown devices." Here's how to check:

1. Download the Mi Home app (for Android/iOS) or Mi Fit app (if the scales are already linked to your account).
2. Sign up or sign in to your Xiaomi account.
3. Click Add Device (+) → Select Smart Home → Libra
4. Follow the instructions on the screen: turn on the scales (click on them with your foot), wait for the indicator to blink.
5. If the scales are original, they will appear on the Mi Smart Scale 2 list of devices. Counterfeiting can be displayed as Unknown device, Smart Scale (without Mi), or not at all.

After successful connection, check the firmware version:

1. Open the scale card in Mi Home.
2. Go to Settings. → About the device.
3. The original scales have a firmware version 1.2.3_0039 For fakes, the version often starts with 0.9.x or contains random symbols.

Official Mi Home app (not cloned) installed

Libra is in pairing mode (flashing indicator)

The device is called Mi Smart Scale 2 (not Unknown).

The version of the firmware corresponds to the original (1.2.3_0039 or newer)

-->

If the scales are not connected, try resetting them to factory settings: press and hold the reset button (located under the battery compartment cover) for 10 seconds until the indicator blinks 3 times.

💡

If the scales are plugged in but show the wrong weight (e.g. your 70kg is displayed as 65kg), this is a sure sign of a fake.The original Xiaomi Smart Scale 2 has a margin of error of no more than ±100 grams when calibrated.

4. Checking the serial number on the Xiaomi website

Each Xiaomi device has a unique serial number that can be checked on the official website.

1. Find the serial number on the box or bottom of the scale (LXMXXXXXXXXXXXX format).
2. Go to the authentication page: mi.com/global/verify.
3. Enter the serial number and code from the picture.
4. If the device is original, the system will show the model (Mi Smart Scale 2) and the date of production.

Note that some fakes use stolen serial numbers from the original devices, and if the number has been checked but the scales are not connected to the Mi Home or have other signs of counterfeiting, this is a reason to return.

If the serial number on the box and on the scales do not match, it is 100% fake, and you should also be alert if the number is erased when rubbed (the original numbers are laser-marked and not erased).

5. Test of accuracy of measurements: how to detect counterfeit without instruments

The original Xiaomi Smart Scale 2 undergo factory calibration and have an error of no more than ± 100 grams. Fakes are often “lies” by 300-500 grams.

1. Bead test: take an object with a known weight (for example, a pack of sugar - 1 kg or a bottle of water - 500 ml). Put on a scale and compare the readings. The original will show the weight with a minimum error.
2. Repeatability test: stand on the scale 5 times in a row. the original will show the same weight (scatter ± 50 g), fake - different values (scatter ± 200-300 g).
3. Impedance test: original scales measure not only weight but also body composition (muscle, fat, water).

Another way is to compare it to a pharmacy scale: put a phone on a pharmacy scale, write down the weight, then repeat the measurement on Smart Scale 2. If the difference is greater than 100 grams, the device is likely fake.

💡

Fakes often "overstate" muscle mass and "understate" fat percentages to make the user seem "healthier." The original scales show realistic data that may differ from expectations.

Also pay attention to the measurement time: the original scales give the result in 2-3 seconds, fakes can “think” 5-10 seconds or give an Err error.

6. Hardware tag check: secrets that vendors keep silent about

The original Xiaomi Smart Scale 2 has a few hidden tags that are hard to fake, and it requires accuracy to verify them, but it gives 100% results:

• 🔧 Label on the board: remove the battery lid and look at the circuit board. MS2-V1.2 or MS2-V1.3 (For the 2021-2023 audits, counterfeits are not labeled or have a different code (e.g., a fake code, MS1).
• 🔋 Battery compartment: in the original contacts for batteries gilded, the copies - ordinary copper or steel (over time oxidized).
• 📡 Bluetooth module: original scales use Nordic chip nRF52832. If you have a Bluetooth scanner (like the nRF Connect app), check the device name – it should start with a new one. MI_SCALE.

Also note the quality of soldering: on the original board, all elements are neatly soldered, without solder leaks or sticking wires. Counterfeit products often show traces of hand soldering, uneven tracks or lack of protective varnish.

If you are not sure about your skills, it is better to contact the Xiaomi service center for diagnostics. In most cities of Russia, authentication takes 1-2 days and costs 300-500 rubles.

7 Where to buy so as not to run into a fake

Even if you have checked the scales on all counts, the risk of buying a fake remains. Here are reliable sources for buying the original Xiaomi Smart Scale 2:

• 🏬 Official Xiaomi Store (mi.com/ru) — Original guarantee, but price is higher than the market.
• 🛒 Authorized dealers: "Svyaznoy", "M. Video", "Eldorado" (check the availability of the certificate on the window).
