I recently purchased multiple Wyze Scales and wanted to sync them across both my phone and my wife’s phone. At first, it seemed a bit tricky, but after some experimentation, I found a great solution! 
Initially, we were only able to sync one scale per device, which wasn’t ideal since we have scales in different locations—like our vacation home and multiple bathrooms. After some research, I discovered that you can actually add multiple scales to the Wyze app. The key is to ensure each scale is properly paired and then select the ‘Add New Scale’ option in the app settings. 
Now, no matter which scale we step on, the data shows up in both our apps seamlessly! It’s been a lifesaver for tracking our progress consistently. Plus, having all the data in one place makes it easier to monitor trends over time. 
If anyone else is looking to set this up, I’d recommend taking it step by step. Make sure each scale is fully charged and in range before pairing, and don’t hesitate to reach out if you run into any issues. Happy syncing!
