I've had ezshare wifi cards in my Airsense 11 and my wife's Aircurve 10 since I found a reference to them on here. But I found the available shell scripts to be unreliable, gave up and just treated them like normal SD Cards.
So... I figured I'd try and tackle a Python program that would do the job.
https://github.com/JCOvergaar/CPAP-data-...ZShare-SD/
I only had Resmed cards to work with (I'm still nagging my buddy to loan me a card from his Philips machine), so I was only able to make a generic version for other systems.
The Resmed-specific version allows you to customize the start date for download, whether to overwrite things, etc.
Since I know nothing about the formats of SD cards for other systems, the generic one doesn't have any features like that.
Both of them have an option to make it easier to use on a Mac by automatically switching wifi networks and back. Other systems require elevated permissions for this and looked like a pain to include.
Feel free to fork or whatever if you want to add specific functionality in support of other system's data formats
Hope this is useful to someone!
(There are lots of places to buy the ezshare cards on eBay or aliexpress and other sites, here's the specific listing I purchased mine from:
