The Dexcom G4 is a continuous glucose monitoring system (CGMS) worn by type 1 diabetics. It has a USB port and Windows only software for downloading and analysing data. A team of developers / users have created an open source realtime remote monitoring, alarm and glucose prediction system for it. It uses a USB OTG cable to connect the Dexcom to a commodity Android phone, which runs a custom Android app to upload the data to MongoLab. From there, a Node.js powered dashboard gives viewers - typically parents of diabetic children - a way to monitor glucose levels remotely. In addition, a Pebble watch app lets the wearer check their glucose by just looking at their wrist, instead of having to use the bulky Dexcom monitor. http://nightscout.github.io/posts/01-quickstart/ http://nightscout.github.io/posts/01-quickstart/

Impressive! And something I could see myself doing at some point, too... Any idea if anything like this is possible for a Medtronic CGM? Their latest model has very good pump integration but I want real-time electronic data too.

  Medtronic pump and CGM integration is work in progress - any help would be really valuable to the project. Ben West is reverse engineering the Medtronic protocol, this code can download pump settings and historic data https://github.com/bewest/decoding-carelink/tree/cgm/touch-ups https://github.com/bewest/decoding-carelink/tree/cgm/touch-u...

    Awesome. I don't have one of these yet, but I'll certainly check this out when I do. The most important thing is to know that the hardware support is there -- to paraphrase xkcd, the rest is software and I'm sure it will happen eventually.

Is that illegal? Will those parents be charged with altering safety devices in case of accident? I'm perfectly aware how good it is, but insurances and labs don't really care about that.
