BLESleep: A project to implement sleep tracking and nightmare interruption on Linux using the Mi Band 4 fitness tracker
It is inspired by the "Nightware" device, which is an FDA approved medical device: https://www.fda.gov/news-events/press-announcements/fda-permits-marketing-new-device-designed-reduce-sleep-disturbance-related-nightmares-certain-adults

This project is based on the satcar77/miband4 project.

USAGE: 
You will need to create two .txt files in the base directory:
  auth_key.txt: the authentication key for your miband 4.  See https://github.com/argrento/huami-token for details on obtaining this.
  mac.txt: the Bluetooth MAC address for your miband 4.


CURRENT STATUS:
Right now the project does not yet fulfill its purpose.  
If you execute the project as-is, it will connect to the miband and plot HR and gyroscope data to the screen.
I'm currently working on massaging the returned data to create signals that can be usefully incorporated into a detection algorithm.

GOALS:
* Publish statistics to Google Sheets or other easy-to-use target.  I'd like to make this usable by non-technical folks, so S3 buckets and CloudWatch are out of scope.
* Incorporate an LSTM neural network as the detection algorithm.  This will require a dedicated "training period", as each user will likely produce different signals.
* Create a GUI dashboard to display sleep statistics and other controls.  My vision for the end product is a standalone RasPi device with a 7" touchscreen display.
* Add support for multiple (cheap) fitness trackers.  I'd like this work to be usable by low-income folks who can't afford Apple Watches.
* Create a framework to incorporate additional biometrics/signals as they become available.  For example, SpO2, galvanic skin response, respiration, BP, etc.
* Create a holistic sleep-tracking interface to provide users the ability to clearly observe the effects of things like changes in routine, medication, diet, etc.
