There's also Loop on the iOS side: https://github.com/LoopKit/Loop. I've been using it for 7 or 8 years. There's also several pumps that have closed loop capabilities built-in, but I've found that they try so hard to play it safe that they are less capable than running your own.

Agreed. My daughter (5) is using a G6 + TSlim X2 closed loop. The target blood glucose is 6.0 mmol/L and you can't decrease it. However, I haven't tried (and likely won't try) anything DIY since it's my daughter and not myself.

Despite this, it is nice whilst my daughter is at school, since some automated corrections (even if overly conservative) are certainly better than none — teachers generally won't administer corrections (but will bolus for food).

As someone who’s planning to start a TSlim, this is a bit worrying. Admittedly even an average value of 7mmol would be an improvement over where I am, but I’ve certainly heard the lack of aggressiveness as an issue with the controlIQ system (if that’s what your daughter is using).
