  14. 14. Uploading to Nightscout using iPhone and RileyLink
  15. 15. Data in the cloud! (nightscout) • BG data • Insulin treatments • Carb amounts • Pump Status • Provided remote monitoring and alerting before Dexcom Share, and before Minimed Connect • Allowed us to call grandparents when Riley was headed for a harsh low, and wake them up to get her treated.
  16. 16. Closing the Loop • Loop on iOS • Insulin delivery automation • Integration with Nightscout • Bolus from your Apple Watch!
  17. 17. • RileyLink is not a Medical Device, it is a radio bridge. • It makes no medical decisions and is non-functional without external control. • It is more like a bluetooth dongle than an insulin pump. • It can be used to control other devices in the sub- ghz space, like home automation devices.
  18. 18. Production • Through community effort, regular batches are being made for the community • Testing and installing firmware • Order handling • Shipping • getrileylink.azurewebsites.net
