Wi-Fi Vs Bluetooth: A Quick Look At The New MGB Scales With Wi-Fi

Until recently, I wanted to choose the topic “Reasoning” for this post, because at the end of 2K21, writing a review of smart scales is already bad manners. Nevertheless, I will try to make this post at least somewhat interesting for you!

Traditionally, I will try to be as brief as possible, especially since 4 years ago I already wrote for you a review of the Bluetooth version of the scale and I hope that you, of course, remember it. (joke, I forgot about it myself). I have selected the most interesting points that may interest you.


Bioimpedance technology itself is limited, so scale manufacturers try to stand out not in performance characteristics, but in some other parameters. The classic feature of MGB scales, and the Wi-Fi version is no exception, is the size.

In my opinion, an extra couple of centimeters in such a product still play a role. Such scales lag behind the most popular modern models.

They are rather standard in height – a couple of centimeters from the floor. As a form for electrodes, the traditional circle has supplanted the original “petals” of previous generations.


Obviously, this parameter will play a decisive role for such a gadget. The scales have a step of 100 grams, they are quite sensitive and accurate in their measurement system. I do not check the scales for accuracy by comparing them with others, because from experience there will always be a discrepancy of a hundred or two grams between two gadgets. I compare measurements in a short period of time, that is, it is even more likely to be reproducible.

So, the scales should not “jump”.

The first measurement in time (highlighted in red) is a test for “sensitivity”. I always recommend that everyone put the scale in the same place, a flat, smooth surface. The example in the circle is setting the weights to the junction of tiles.

Rubberized inserts on “legs” help to make the scales stable and well fixed.


Wi-Fi MGB works on the basis of bio-medance analysis technology. In order to get detailed results, let me remind you that you should stand on the surface with bare feet.

In this case, a weak current will analyze the resistance of body tissues and will be able to show you what percentage of fat mass, muscle mass, bone mass and other parameters you have. Each of them has its own level of generalization and its own value, which I also seem to have already talked about in the same publication.

To save your time, I will show just one example, from my personal experience.

You can be quite thin and not weigh that much. Well, that is, to be like me: ok. 69 kg. But at the same time being “fat”, and at one time it became an interesting discovery for me that with a normal weight and body type in general, my percentage of fat is excessive (I checked this later even on DEXA).

In fact, it is impossible to notice it with the naked eye, but with smart scales – please. The task is actually not so simple: there is nowhere to lose weight, otherwise the wind will blow away, and the percentage of fat must be somehow reduced. That is, it turns out that I must either “lose weight by gaining weight” in order to balance it, or keep the current weight, somehow increasing the muscle mass. It is for the sake of such small wonderful discoveries, in fact, such scales are needed.

Finally, the application

And now I would like to move on to one seemingly insignificant advantage, namely Wi-Fi. On the one hand, Wi-Fi seems to be the least needed for such a household gadget, however, it seems to me that the scales underestimate it.

Now there are many companies that are building their ecosystems. But there are even more separate scattered brands that do not have such an opportunity either for hardware or software.

There are many users who join large ecosystems. But, again, my experience is different: I have devices from different manufacturers and, of course, I would like to somehow connect them. Otherwise it is comical. You need to put the kettle on – open one application; you need to turn on the light – another; you manage the kondeem – the third; to weigh in – the fourth … and there is no end to it.

Some applications, as you are familiar with, I guess Tuya allows you to combine different devices, and Wi-Fi scales MGB are added to it. This is generally convenient. You can create your own ecosystem of hardware that is convenient and attractive to you.

You do not need to install anything, you do not need to log in additionally anywhere. Just add the scales! (like if sang).

The second important point is in the Wi-Fi format itself. Most Bluetooth scales require when using an open and running application, where data is transferred. On the one hand, it’s not really a problem. But by God: put the kettle on – open the app, turn on the light – open the app, weigh yourself – open the app …

Wi-Fi makes it possible to implement certain scenarios without a smartphone. Many of these scenarios have long obeyed voice commands, which does not work with weights yet: they will not crawl out from under the sofa at your call.

However – happiness – you can weigh yourself with Wi-Fi scales without a smartphone! That is, you don’t need to put it next to it, you don’t need to hold it in your hands, you don’t need to open the application. He weighed in and went on about his business, and then he looked to see what was there.

Therefore, more and more people, in fact, in the confrontation between Wi-Fi and Bluetooth began to choose exactly Wi-Fi. Yes, and I believe that Wi-Fi sync will soon finally defeat BLE.
