It's pretty amazing how much data this relatively cheap device makes available over BLE, and how easy it is to access that data.

Is there a list of health monitoring devices that can be read programmatically without requiring proprietary software or uploading data to the cloud?

I was hoping to intercept and reverse-engineer the protocol of the Oura rings.

For some reason, I thought this kind of device would attract a lot of hackers given the platform capabilities but I could not f8nd any other documented attempt except the really thorough iFixit (destructive) teardown : https://www.ifixit.com/Teardown/Oura+Ring+2+Teardown/135207

I know the device uses BLE - I'd start with seeing if there is any data included in the BLE broadcast

I think most bluetooth low energy devices can be connected to quite easily programmatically as long as you know the data specification. Polar use to publish their data spec on their website but took it down a few years ago so I had to search around to find it.
