EzShare ResMed

This script assists in using a WiFi enabled SD card by EzShare in your CPAP/BiPap device. This is coded for use with most ResMed devices from version 9 and up. Feel free to fork it for use with Philips Respironics and other devices.

The program runs on Python 3, and requires dependencies to be installed. Python versions 3.9 to 3.12 have been tested.

Data Save Location

• Windows: C:\Users\<USERNAME>\Documents\CPAP_Data
• macOS: /Users/<USERNAME>/Documents/CPAP_Data
• Linux: /home/<USERNAME>/Documents/CPAP_Data

Configuration

Configuration to set the default parameters is done with a config.ini file.

Example config.ini

[ezshare_resmed]
path = ~/Documents/CPAP_Data/SD_card
url = http://192.168.4.1/dir?dir=A:
start_from = 20230924
day_count = 5
show_progress = True
verbose = False
overwrite = False
keep_old = False
ignore = JOURNAL.JNL,ezshare.cfg,System Volume Information
ssid = ez Share
psk = 88888888
retries = 5

Configuration file locations

ezshare_resmed looks for config files in this order:

• ./ezshare_resmed.ini - in the same directory as the script
• ./config.ini - in the same directory as the script
• ~/.config/ezshare_resmed.ini
• ~/.config/ezshare_resmed/ezshare_resmed.ini
• ~/.config/ezshare_resmed/config.ini

Setup

1. Install Python 3
2. Download repository
3. Run installer script

Install ezshare_resmed

• Install on Windows
• Install on macOS/Linux

Winndows Setup

1. Open command window
2. Run: cd CPAP-data-from-EZShare-SD
3. Run: install_ezshare.bat
4. The program, ezshare_resmed, is installed in %USERPROFILE%\.local\bin which will be added to the user %PATH% if it was not already, in which case a new command window will need to be opened
5. Run: ezshare_resmed

macOS/Linux Setup

1. Open your Terminal application
2. Run: cd CPAP-data-from-EZShare-SD
3. Run: ./install_ezshare.sh
4. The program, ezshare_resmed, is installed in $HOME/.local/bin, if it is not already in the $PATH run:

• bash: echo 'export PATH="\$HOME/.local/bin:\$PATH"' >> ~/.bashrc && source ~/.bashrc
• zsh: echo 'export PATH="\$HOME/.local/bin:\$PATH"' >> ~/.zshrc && source ~/.zshrc

5. Run: ezshare_resmed

Install Python 3

A Quick Guide for Installing Python 3 on Common Operating Systems

• Install on Windows
• Install on macOS
• Install on Linux

Windows

1. Open a command window, Run: winget install -e --id Python.Python.3.12

2. Once Python is installed, you should be able to open a command window, type python, hit ENTER, and see a Python prompt opened. Type quit() to exit it. You should also be able to run the command pip and see its options. If both of these work, then you are ready to go.

• If you cannot run python or pip from a command prompt, you may need to add the Python installation directory path to the Windows PATH variable
  • The easiest way to do this is to find the new shortcut for Python in your start menu, right-click on the shortcut, and find the folder path for the python.exe file
    • For Python3, this will likely be something like C:\Users\<USERNAME>\AppData\Local\Programs\Python\Python312
  • Open your Advanced System Settings window, navigate to the "Advanced" tab, and click the "Environment Variables" button
  • Create a new system variable:
    • Variable name: PYTHON_HOME
    • Variable value: <your_python_installation_directory>
  • Now modify the PATH system variable by appending the text ;%PYTHON_HOME%\;%PYTHON_HOME%;%PYTHON_HOME%\Scripts\ to the end of it.
  • Close out your windows, open a command window and make sure you can run the commands python and pip

macOS

macOS comes with a native version of Python but it is not recommended to use the native Python in order to not alter the system environment. There are a couple of ways we can install Python3 but this script is only tested using Homebrew.

Install with Homebrew

Homebrew is a MacOS Linux-like package manager. Walk through the below steps to install Homebrew and an updated Python interpreter along with it.

1. Open your Terminal application and run: xcode-select --install. This will open a window. Click 'Get Xcode' and install it from the app store.
2. Install Homebrew. Run: /bin/bash -c "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/HEAD/install.sh)"
   • You can also find this command on the Homebrew website
3. Install latest Python3 with brew install python
4. Once Python is installed, you should be able to open your Terminal application, type python3, hit ENTER, and see a Python 3.X.X prompt opened. Type quit() to exit it. You should also be able to run the command pip3 and see its options. If both of these work, then you are ready to go.

Linux

• Raspberry Pi OS may need Python and PIP
  • Install them: sudo apt install -y python3-pip
• Debian (Ubuntu) distributions may need Python and PIP
  • Update the list of available APT repos with sudo apt update
  • Install Python and PIP: sudo apt install -y python3-pip
• RHEL (CentOS) distributions usually need PIP
  • Install the EPEL package: sudo yum install -y epel-release
  • Install PIP: sudo yum install -y python3-pip
• Arch may need Python and PIP
  • Refresh pacman database and update system: sudo pacman -Syu
  • Install PIP: sudo pacman -S python python-pip
