I searched for a long time with wi-fi and as it turned out, few people do it, and if they do, the price is much higher. A huge advantage is the work through wi-fi. Before that, there were "Smart Scales" by Xiomi, which is smart in them, except for the name, it is not clear. Connecting to the phone via Bluetooth, got on the scales, turned on the phone, went into the application, horror. Then he stood on the scales, tears, sat down to drink coffee and look, weight and everything else. Dynamics of change and so on. You can call them smart.
