Does the Herz P1 Smart Scale auto-detect work if two people are close in weight?

The auto-recognition thing works on weight as the main trigger, but if you and your partner are within a couple kilos it really is just a coin toss which profile it picks. I ran into that with mine and honestly the smart features dont help much when the numbers are that close. I gave up relying on it and just check the app before I trust any reading. If it logs under the wrong name, the trend data gets messy and that defeats the whole point of tracking. I would say keep an eye on it for a week and see if it actually figures out the pattern, but I wouldnt hold your breath. The tech is decent for a single user, but multi-person stuff feels like an afterthought when the weights overlap.

Weirdly mine has been fine with this exact situation. My roommate and I are within maybe 1.5 kilos of each other and it’s never logged us wrong. I think it uses more than just weight, maybe the body composition readings from the handle scan, because we’re built totally different and it seems to tell us apart. Might just be lucky though.

We have this exact situation at home actually. My husband and I are barely a kilo apart most mornings and the scale has never once put my weigh-in under his name. I don’t know how it decides, but it hasn’t messed up once in the few months we’ve had it. I just make sure we each step on around the same time every day so the app has a consistent pattern to go off.

I’ve seen people mention weight being the deciding factor, but for us the bigger issue was that it kept recognizing my partner as me whenever we weighed in around the same time of day. We started weighing at different times just to avoid the confusion, which kind of defeats the purpose of auto-recognition.

I think it kind of depends on how the app decides who is who. Ours isn’t the Herz, but a similar one, and my sister and I had this issue where we were almost exactly the same weight for a while. It would sometimes log us under the wrong name if we weighed in around the same time of day. We figured out that if we weighed in at different times, it was usually fine, but back to back it got confused.

What we started doing was just checking the app after we stepped off to make sure it picked the right person. If it didn’t, it takes like two seconds to move the entry to the other profile. A bit annoying, but not a huge deal. I would say just pay attention for the first week or so and see if it actually mixes you up. If it does, you’ll probably notice a pattern and can work around it.

The auto-recognition is basically comparing last known weight and sometimes body metrics to guess who’s on it. If you two are that close, it’s going to be a gamble every morning. I’d just check the app after stepping off and correct it manually if it’s wrong, otherwise you’ll end up with mixed data in your history.
