This is very cool. I am fortunate enough to have access to a pump and have been hacking closed loops for a few years now using software like Nightscout, AndroidAAPS and xDrip+. My understanding is that none of these are exclusive to pump users, they just work a little easier with them. Maybe there is some interplay with these tools that you can leverage?
