Maybe it works with other models?
Does not support live data.

Thanks! This works with mine too, same model. I had to set the date and time on command line, otherwise SleepyHead messed up the import of the spo2 file.

In Fedora linux, I had to add myself to the "dialout" group to be able to access the oximeter without sudo/root.

RE: Oximetry - Do any of the pulse oximeters work with linux?
Just got my new CMS50-F. I was good, and did my homework so that I could be sure it would work properly with SleepyHead right out of the box. Joke's on me. Instead of having a laptop to old to run SleepyHead properly (only runs OpenGL 1.4, so I run SleepyHead-Broken or nothing), now have hardware that is too new.

Seems the Contec folks have updated their firmware to version 3.8. SleepyHead speaks very directly of version 3.7. On my system I can see the new device at /dev/ttyUSB0 and dmesg gives me all the expected messages when it was identified. lsmod shows me that cp210x has been loaded. But SleepyHead cannot see it no matter what I try. Oh well.

Thanks to an earlier post in this thread I found https://github.com/airikka/spo2cms50dplus which turns out to work just fine when grabbing the raw data off my device and stashing it in a file. I was then able to import that file into SleepyHead, but see only summary info like max/min Sp02. I somehow expected a chronology of some sort. Is that only possible using the device tethered to a PC? I have not tried tethering yet, but am not optimistic.

I also have a CMS-50F with the 3.8 software. I was able to import the data, although it was a bit fussy. I don't use it all that often, so I can't tell you what I've done to make it work. I will experiment more when I return from vacation.

You have to modify the date and time of the data with the spo2cms50dplus program. Otherwise it will put the data on some random day.

Pholynyk -- thanks for the observation, maybe I can find something on my system that will allow SleepyHead to see my CMS50F.

Johanh -- yes! I didn't understand before that the date HAD to be corrected. Even SleepyHead gave me the option, but I ignored it the first time. As I recall, it showed me an empty box for date/time. On the successful pass, it showed me that date/time I had just forced in with spo2cms50dplus.

In this case there is a bug in Sleepyhead. I was able to correct the time, but the calendar in the import dialog was messed up. Best bet is is to correct date and time before importing.
