You should check the project gadgetbridge[1]. Its aim is close to what you want to achieve : an opensource app to retrieve data and monitor without sending it god know where. I have used it for 2 years now with an amazfit bip, which was never sync with the official app, not even once. The project is really active, with roughtly a new release every month.

I considered to Amazfit Bip and while shopping I saw the Amazfit Bip Lite. One thing I've read is that Amazfit/Huami/Xiaomi started putting a server-side activation on their newer devices, so I'm not sure I want to passively reward that kind of behaviour by buying their hardware..

good suggestion, thanks. The only issue is that it's Android only, and many patients have iPhones. One thing I could do though is extracting the implementation of one (or more) of the Bluetooth protocols and make an iOS version of it.
