After I understood that the format is currently only found if it is
in the current folder I could test it. 

Like with harftex you have to use harfload and activate the harf
mode to get the right output. 

So something like this:

\documentclass{article}
\usepackage{harfload}
\usepackage{fontspec}

\newfontfamily\deva[Script=Devanagari,RawFeature={mode=harf}]{NotoSansDevanagari-Regular.ttf}
