I used to monitor CO2 in the house with Awair units, specifically those because it allegedly interacted with my Ecobee AC control. So I could say if the levels were rising, force the fan on to push fresh air around, although I'm not sure I ever got it working correctly.

It's a big problem for me, as living in Florida basically means the AC runs almost year round. In the colder months we open the windows as much as we can to let the levels drop, but from spring through autumn it's just too hot to keep them open, as it just pushes the AC harder to cool more and more, while also increasing the humidity.

We definitely started getting better nights sleep once we had either the windows open, or the door to the bedroom open. I also rarely shut the door to my office as I was getting so sleepy at my desk during the afternoons.

I have no real solution for the hot months anymore, as Awair has basically abandoned the units I was using. I've just had some Zigbee air quality monitors arrive that I ordered on Aliexpress, but I'm skeptical at how accurate they'll be. Infact I'm skeptical at how accurate any of them are after I did some research into building my own and adding some sensors to an ESP32.

Going to have to try and come up with some HomeAssistant automation task with the Zigbee sensors and Ecobee to push fresh air through the house.
