An open source Python client to read data from Colmi R02 smartrings #Wearables #OpenSource #Python

colmi_r02_client is an open source Python client to read data from the Colmi R02 family of Smart Rings. It is 100% open source, 100% offline.

What is the Colmi R02 family?

It’s a cheap (as in $20) “smart ring” / fitness wearable sold on AliExpress.

It includes the following sensors:

  • Accelerometer
    • step tracking
    • sleep tracking
    • gestures (maybe…?)
  • Heart Rate (HR)
  • Blood Oxygen (SPO2)

Wesley Ellis has been reverse engineering the Colmi to get data without their app.

Check out the page on GitHub.io and the docs page. This page is a “stream of conscience” of the project and the GitHub site.

    Most excellent, been way long time since I did any coding, but this Colmi has me captivated enough to push me over the edge and get back into it. If only this feeble brain can hang in there long enough for me to get to the meat of the R02 smartring! Thanks for bringing it bac to “Face the workbench and pick up the screwdriver.”
