My son is T1D since age 7. He is now on the OmniPod pump and the Dexcom G6 sensor. It’s been a very effective combination that’s covered by insurance. The challenge with the open source projects is limited equipment that can be hacked.
Most people on loop have omnipod and dexcom g6 also so I don’t think it’s that limited. It’s true that it takes a few months for new devices to get integrated but open source APS are the only systems lets you choose what devices you want to use with them.
