Automated insulin dosing systems like Loop are not for everyone. People part of the #WeAreNotWaiting movement believe that progress toward better treatments for diabetes has been much too slow. Here is a statement of their beliefs taken from the Looped Facebook page:
Looped is an an open and transparent effort to make safe and effective basic closed loop technology widely available to reduce the burden of Type 1 diabetes. The members are not willing to wait for an approved solution and instead are using Loop. The system is not something that you can purchase from a manufacturer but a system that requires work to install, support to use and equipment to purchase. If you want a perfect system, this is not for you. Support and troubleshooting is available here for OpenAPS, AndroidAPS and Loop system users.
I use the Loop automated insulin dosing system and follow a few online groups populated with people like me. I don’t know the answer to your question about reverse engineering the communication protocol of the 670G. I think this new technology, unlike the older pumps, is likely locked down well.
The do-it-yourself open source movement is grassroots and does not have a budget, at all. All the current DIY automated insulin dosing platforms came about due to the altruistic efforts of talented people. They made a strategic decision several years ago to spend their volunteer time on the “low hanging fruit.” That’s why the systems are usually based on older pumps.
By the way, the 670G sensor, the Guardian 3, by all reports I’ve read, is a very good sensor, comparable to the Dexcom G5.
Your wariness of the DIY open source automated insulin dosing systems is rational but many of us who have adopted this technology believe that the current diabetes treatment status quo is riskier than the thoughtful, vigilant, and intelligent use of these DIY systems.
