Many people are controlling their insulin pumps via phone and watch apps: https://github.com/LoopKit/Loop

The app tries to predict blood glucose in the future (drawing on CGM, food intake, lots of parameters and other data) and based on that either automatically injects insulin, or asks the user to confirm.

People need to compile the app themselves because the liability in the case of adverse effects is insanely high.

It’s a highly driven community. I’ve seldom seen such a useful and well supported application of modern tech.

Reminds me of Barnaby Jack [0] who in 2011/2012 "demonstrated that he could wirelessly hack the insulin pump from a distance of up to 90 metres using the high-gain antenna". That was based on the hardware and not even all kinds of smart cloud-connected apps having bugs to exploit.

On the other hand, those OSS closed loop systems are only possible because of such vulnerabilities that allowed reverse engineering.
