What would happen if you fart on it? I guess that would be a test to see if it actually does anything.

No WiFi or Bluetooth connectivity, and the battery only lasts ~24 hours. Definitely not as useful as some competitors.

does this actually measure co2, hcho, and tvoc or does it cheat like ecobee does and infer them based upon a single measured particle count and then say "meh this sounds good enough" for the others.

Arent these junk with pretty much fake sensors? They were $13ish last year on temmuu and i got one and it was putting out fake numbers. I assume these are similar quality since its amazon in the US.
