Cheap Hackable Smart Ring Gets a Command Line Client
1 min read
Summary
A smart ring developed by Chinese company Colmi has been opened up for wider development thanks to the work of developer Wesley Ellis, who has created a Python-based client that can connect to and read data from the device.
The ring works using Bluetooth and has a range of functionality including measuring heart rate and tracking daily activity, and can be used with the QRing app that comes with it.
Ellis’ work connects to the ring without the need for pairing, as no encryption is present in the device, and is intended to allow users to integrate the ring’s functionality into other smart projects.
The original hack and reverse engineering of the ring is also documented, with the code available on GitHub for others to use in their projects and for further development.
