Frequent waking

I have been using the Resmed Airsense Autoset for Her for a little over a year and I use the Brevida nasal pillows mask. I wake up at least every two hours every night with a dry mouth and needing to go to the bathroom. My numbers always show an AHI of less than 2...usually less than 1. Disrupted sleep is causing me to feel very tired all the time. I have problems getting sleepy enough to go to bed. Is frequent waking a common issue with cpap usage or does it indicate some changes are necessary in my therapy?

I have sleep maintenance issues, though getting to sleep initially is rarely a problem. My AHI is similar to yours and my timeline of wake ups is pretty similar as well, though dry mouth and needing to relieve myself are rare at night. Taking 1.5mg of melatonin along with some caffeine free hot tea assures that I crash quickly. Of course, I also try to exercise most days as well. Either swimming or spinning. Curious to hear what other opinions you get.

I started taking 3 mg of melatonin and it has worked for me

I presume you are using the humidifier and the heated hose with the settings in Auto? If you are not using the heated hose, you might gain some comfort by using one.

The dry mouth makes me wonder if you are opening your mouth during the night allowing air to leak out? The best way to determine that is to download SleepyHead and view your detailed data on a computer. Areas where the leakage flow is high with a flat top indicates mouth leakage. Some of us use mouth taping to stop the mouth leak issue.

My preference is a nasal pillows mask but traditionally, I am a mouth breather. I have tried a chin strap and mouth taping. However, what has worked best for me is to consciously throughout the day to place my tongue in the roof of my mouth to create a habit of keeping my mouth closed. Over a short period of time creating that habit has helped me keep my mouth shut and ended the dry mouth most nights. I now find myself unconsciously and routinely resting my tongue day and night in the roof of my mouth. Just the awareness of realizing that when my tongue was at rest in the roof of my mouth, my mouth is automatically closed and I am breathing through my nose helped me begin creating that new habit.
