Writing a loader is not easy and we have several other more popular machines that do report detailed data that we would like to support. So we will not be adding Z1 / Z2 support in the near future If a skilled QT / C++ programmer wanted to undertake the task, we certainly would have no objection and would welcome their participation.
Longer answer: How do people use OSCAR to examine their therapy and determine what changes might, or might not, be useful? Key factors are often the exact timing of events and comparisons with breath shapes and pressure. Breath shape alone says a lot about what is going on and what the problems are. To examine breath shape and correlate with events, you have to have high resolution breath flow data (for example, air flow recorded every 40 milliseconds). With that data, you can answer questions like whether an apnea caused an arousal, or whether an arousal caused misreporting of an apnea, with very different things you can do about such events. All of the charts on the OSCAR Daily page are based on such data.
The Z1 and Z2 machines simply do not report the kind of data needed to answer such questions. They do not report breath flow data at all. The highest resolution data seems to be once every 10 minutes with summary data reported every 30 minutes. While such data could be plotted on a graph, perhaps more effectively than HDM DataViewer does, making therapy evaluations based on that data would not be easy or reliable. We try to focus our programming resources on products that are in common use so that OSCAR can be the greatest benefit to the greatest number of people.
We do have plans to re-organize the loader architecture on OSCAR to make adding new loaders easier. That won't happen immediately.
With your permission, I would like to retain your data on file. We do like to keep sample data from the many different machines available for our own education.
Sorry I couldn't give you a more positive answer.
I have loaded almost 5 years of data from SD cards with helpful analysis from OSCAR.
