Self-Monitor stores data from Health Connect API on Android to InfluxDB for further visualization with Grafana

Note that this project isn't sufficient to reproduce all the features of https://www.kshivendu.dev/blog/quantified-self. I made many changes that are yet to be pushed to this repo. I plan to do it soon.

The platform consists of two parts:

• A REST API/server
• A mobile application that pings the server periodically

• The mobile application pings the server every 2 hours to send data. The following data types are supported-
  • Basal Metabolic Rate (basalMetabolicRate)
  • Blood Glucose (bloodGlucose)
  • Blood Pressure (bloodPressure)
  • Body Fat (bodyFat)
  • Distance (distance)
  • Exercise (exerciseSession)
  • Heart Rate (heartRate)
  • Height (height)
  • Nutrition (nutrition)
  • Oxygen Saturation (oxygenSaturation)
  • Power (power)
  • Sleep (sleepSession)
  • Speed (speed)
  • Steps (steps)
  • Total Calories Burned (totalCaloriesBurned)
  • VO2 Max (vo2Max)
  • Weight (weight)

Support for more types is planned for the future.

• Each sync takes approximatly 15 minutes
• The server encrypts the data using Fernet encryption, then stores it in a database hosted on a custom instance of Appwrite.
• The server exposes an API to let developers login and get the data for their users.

The platform is currently a one way sync. Any changes made to health connect data by other apps will not be synced. The ability to add/edit/delete data through the api is planned for the future.

• You can install the mobile application through the APK file. You can find the latest APK file in the releases section of this repository, or by downloading the app-release.apk file from the root of this repository.
• The minimum requirement for the APK file is Android Oreo (8.0)
• Once you install the Android APK file, signup by entering a username and password
• Once you see a screen showing your user id, you have successfully signed up. Your data will sync in 2 hours. You can also force it to start now by going to Settings > Apps > HCGateway > Force Stop, then re-opening the app. This can be done for any time you want to force a sync.

You can self host the server and database. To do this, follow the steps below:

• You need Python 3 and NodeJS 16+ installed on your machine
• Install InfluxDB and make sure your instance is accessible from the machine running the server.
• Clone this repository
• cd into the api/ folder
• run pip install -r requirements.txt
• rename .env.example to .env and fill in the values
• run python3 main.py to start the server
• in another window/tab, cd into the app/ folder
• Change lines 104, 112, and 154 of app/App.js to point to your HCGateway server
• run npm install
• run npm run android to start the application, or follow the instructions at https://medium.com/geekculture/react-native-generate-apk-debug-and-release-apk-4e9981a2ea51 to build an APK file.

The original repo was created by shuchir.dev. I made lots of changes afterwards but I'm grateful that they gave me a starter point for this =)
