Wow you really have a good selection of older MDT pumps. If my memory serves, you need to have a certain firmware on the 523 to make the loop work, but the 522 works on all firmware versions.

```auto
Currently, only the following Medtronic MiniMed models allow us to remotely set temporary basal rate commands, which is required to do OpenAPS:

512/712 (all firmware)
515/715 (all firmware)
522/722 (all firmware)
523/723 (with firmware 2.4A or lower)
554/754 (European Veo, with firmware 2.6A or lower; OR Canadian Veo with firmware 2.7A or lower)

```

On your question about Xdrip vs Nightscout. Nightscout is just a way to get the data out of your system in a usable way. I don’t think it makes any predictions. We set up a nightscout site, but my son wasn’t very interested in it. I think you have to compile your own software solution (reduced liability) to do the predictions. Here is a link to a thread talking about that.
