Whats wrong with this one? (it works with the same device) https://github.com/larsp/co2monitor

Maybe they didn’t know of it? Maybe they liked building their own regardless?

That looks good as well! I actually didn't know about that project. It wouldn't have worked on my specific case though since I wanted it connected to my Mac, that tool only works on Linux.

The Mac doesn't provide a device to read from? Because beyond that, it should be pretty similar (posix-ish and golang)?

Yeah, you have to use IOKit, which hidapi wraps.
