“Smart” meaning does it work with Google Assistant and can add to my Google Home app to retrieve CO levels and warnings remotely?
Hi there. There’s more info on Amazon:
I’m confused… This says carbon dioxide measurements, but carbon dioxide is a normal part of atmospheric air, and there’s not much you can do about how much of it is in your home other than stop breathing.
This doesn’t measure carbon monoxide, which is actually something that shouldn’t be in your home air and is actually dangerous, is that accurate?
LOL 
Good point. I misread the specs thinking it was CO, carbon monoxide. This may be useful in a space capsule to keep track of high CO2 levels. Otherwise, this is just an expensive digital clock with some neat features. Apparently, it can’t connect to your phone, but maybe a laptop from what I read on Amazon
