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:
The project now supports basic "heartrate alarming".  Currently it's configured to send a 10-second random vibration pattern if the heartrate increase percentage goes 
above 17% of the lowest HR value for the last 10 readings, with a 20-minute delay between vibrations.  This was tested on the Miband5, which has a better HR 
sensor, though I've not yet fully figured out the gyroscope data.  Right now only HR and vibration are supported on the Miband5.


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 holistic sleep-tracking interface to provide users the ability to clearly observe the effects of things like changes in routine, medication, diet, etc.
