The Medtronic 670g was my other option, but I took the Animas Vibe + Dexcom G4 just because it's easier to hack, lots of German Diabetes hackers use it, its CGM seems to be more accurate and you can use the G4 sensors way longer than the 670g.

670g is a closed loop system, but what it does is it stops giving you the basal insulin when it thinks you are getting a hypoglycemia soon. What it doesn't do is to give you correct amount of insulin automatically when you've been eating carbs or doing exercise to keep your glucose level in the 5.5 mmol/l target. And with the new Fiasp insulin automatic adjustments would be possible.

To be able to build the OpenAPS, you must have an older Medtronic pump which are not covered by German insurance anymore. My Animas doesn't allow to tweak the insulins remotely.

The 670G completely controls basal rates; the "suspend on low" functionality arrived in a previous generation. But it won't keep your blood glucose at 5.5 mM -- it targets 6.7 mM, and there doesn't seem to be any way to change this. :-/

Sounds nice. I still think I'm going to manage my insulins manually until the next generation of artificial pancreas. This system what I have is already the biggest ever improvement for my diabetes I've ever had.
