Although this is applicable to a few of their models, I’m mostly looking at their newest one, the Ultra. Can someone explain how it keeps user’s data “separate and private” in a household? Having shared users for cameras and doorbell is one thing, but not everyone wants anyone else knowing their weight etc.
You bring up a good point. I have only had the Ultra for 2 days and I am still in a learn mode.
My better half refuses to get on any scale. It is a private matter and I respect that.
But what happens if you have guests and someone steps on the scale?
It is hard to test as it keeps identifying me based on my weight. We are empty nesters so there is no one to test this.
Time permitting I’m going to try a calibrated weight and see what the scale and app do.
There is a “Guest Mode” in the app but it wants to know gender, height and weight. Not that useful.
I’ll post my findings after I test.

I have tested this.
If you share the scale with someone else, they can store their own data on their Wyze account and nobody else will see it (including the scale owner). It stays private. They can ensure their weightings are 100% assigned to their account by making sure to open the app and connect to the scale when they weigh themselves. Then it can’t accidentally think it was another user’s profile and assign the data to the wrong profile or ask where to apply an unclaimed measurement.
If a guest without a Wyze account uses the scale, then when the owner next opens the scale on their Wyze app, it will tell the owner that there are “unclaimed” weightings and ask you if you want to claim them for your profile or a sub-profile on your account. Then you can claim them or delete/reject the measurements that aren’t you or a sub-profile on your Wyze account.
For example, I added my toddlers as sub-profiles on my account so I can track their weight. I also created some for my cats. So I have my own profile and others on my same account, but my wife also has her own account I share to her with so she can track herself on it privately if she wants. Or if my teenage daughter wants to use it for herself privately, she can.

Thanks @carverofchoice,
This makes sense. Good to know. The “unclaimed” operation was my missing link.

What happens if they don’t open the app when weighing themselves? Does it sit in a cache that it uploads to the phone when it does get opened? What happens if another user comes up and weighs themselves before the first one downloads that data?
If the app is always running at least with camera notifications, should it not then send it to the phone regardless?

Because the product page says…
…my expectation would be that any measurements obtained by a Scale Ultra connected to Wi-Fi would almost immediately be transmitted to Wyze’s servers and added to the associated user’s Wyze account/profile. The addition of Wi-Fi seems like a real advantage of this over previous Scale models, which seem to hold data in an on-board cache until a user connects the Scale to the app on a phone via Bluetooth.
I would expect Scale Ultra to have some sort of cache that it uses if it’s not connected to Wi-Fi (for later data retrieval via Bluetooth), but utilizing the Wi-Fi capability seems like the way to go with this one.

That is what I would think/hope as well. However, I’m not sure how it would differentiate who is on the scale without an open app near the person.
Maybe it could (does) use some kind of “user fingerprinting” at setup so if wife gets on and weighs 120 and husband gets on and he is 200, it could use those metrics to “know” which person is on the scale and therefore send the weight to the correct person’s account.

Your second paragraph comports with my understanding of the way these scales differentiate individuals.
That is correct. When the app is not open, the scales mostly “guess” who is using the scale based on previous measurements and trends. If two people are too close to each other, IIRC I believe it sometimes says that it can’t do it automatically.
In this case, if you have it connected to Wi-Fi, it just uploads the data to the wyze account cloud. The measurements from the scale are actually all stored in the cloud, and the phone app connects to the cloud to get that data. This ensures that if you switch phones or something, you don’t lose all your weight data because it’s actually stored on wyze’s servers, or rather AWS. So, in that case there is no need for a cache on the scale because it just uploads to the cloud every single time which is where the phone gets the data from when you open the scale on the app.
However, if the scale doesn’t recognize which profile the weight should be applied to, then the app does hold several measurements in an “unclaimed measurements” list To ask whether you want to claim them or delete them. Recently, I had it tell me there were three or four unclaimed measurements. I deleted some and claimed some. So I do know that it can hold more than one unrecognized measurement in a list. Waiting for you to decide what to do for them. But I do not know what the limit is on unclaimed measurements.

Ok well if it does in fact work that way, that would be helpful and probably the best it could do short of reading your toeprints. I may have to pickup one of these.
Thanks
