Tracking Whoop bands or Oura rings
I don’t know much about BLE but ESP Presence seems to see Whoops in its fingerprints, I don’t know if it’s a private BLE device like iPads/iPhone, etc but it’d be mightly practical.
Also don’t know if the BLE proxies see them (I have three set up, one on each floor) and I don’t know how to figure out what they see and don’t see around them.
Happy to help diagnose with a bit of guidance.
