Do I have to file a non-resident Oregon return if I signed up for health insurance through the Oregon marketplace?

I'm a California resident going to school year round in Oregon. I'm not working, so I don't have earned income, but I have passive income from stocks and bonds. I am filing a California state return but my understanding is that because I did not earn any wages in Oregon, I do not have to file an Oregon non-resident state return.

When in California, I had health insurance through Covered California. When I got to Oregon, I signed up for local health insurance through the Oregon marketplace exchange. Because I'm now receiving health insurance through the Oregon marketplace, do I have to file an Oregon non-resident state return? Will this affect my California state return in any way?
