Hello @ilovedoodie, Welcome to Mayo Clinic Connect. I don't have a modem either on my Dreamstation or my Dreamstation Go. I did like playing with the SleepyHead program and downloading the data from my SD card into the program. I used it for a few months and it was a little information overload for me. I do use the Dreammapper app on my phone to upload the data on the SD card into the app and it also uploads it to the MyDreammapper site -- https://www.mydreammapper.com/Home/Sleep

My daily goal is to improve the AHI and try to keep it under 4.0. A lot of my issue is falling back to sleeping on my back. I get the best numbers sleeping on my side until I have to move due to pain in my hip...wakes me most nights. I think I'm a side sleeper because I have a deviated septum and my nasal path is not always clear so I breath through the mouth a lot. I use a ResMed AirFit F20 full face mask.

Do you currently view your SD card data this way for your Dreamstation?

It's not too hard to install the Windows version of Sleepyhead from your links. You just have to identify whether you have the 32 bit or 64 bit Windows Operating system and download the appropriate version and if you have Kapersky Antivirus you may have to disable it temporarily due to the issue of it thinking it's malware when it's not. You may find it useful as you get to see what the sleep techs see when you take your CPAP machine into your doctor for usage compliance verification.

Your question on updating the Dreamstation firmware - If it were me, I would leave it alone - if it ain't broke, don't fix it. It's easy to brick a device by updating the firmware and have something go wrong and then you have to get a new one. I had an issue with my Dreamstation last year when it was under warranty and had to send it in. It failed the Performance check which you can use to tell if your Dreamstation is working normally.
