CO2 readings impossibly low with windows open

Post by Webslinger »

When I open up windows in my house, I'm sometimes getting readings that are below 400, which is impossibly low in my area.
Outdoor readings are closer to 415 ppm in my area, and my modules are indoors; so I would expect readings that are slightly higher than 415 even with windows open.

You can find what your outdoor CO2 reading should be here: https://earth.nullschool.net/#current/c ... lay=co2sc/
(select your area).

I've performed manual calibration and have left automatic calibration on.

I thought maybe one indoor module (I have 3 plus the main unit) might be defective, but I also have similar readings with another indoor module as well.
