What determines state residency when it comes to robustness insurance?

I live in New York but also rent an apartment in Connecticut. I am not a signatory on the lease (I rent a room contained by a friend's apartment), but sometimes stay there for work. The premiums for health insurance are much lower surrounded by Connecticut than they are in New York, and I was wondering if I could sign up for vigour insurance there. I know I would only be covered surrounded by Connecticut. Is this something I could do and if so, what kind of documentation would I need to provide to prove my Connecticut residency? Thanks

It would follow that rule.
