I think the romance of authenticity is something only old people like me got to experience e.g. the early days of thefacebook. It died a few short years(?) after when the algorithms took over.
Just a heads up, the EcoBee doesn’t use a CO2 sensor, it just guesses what the value is. I have the same thermostat and was getting wildly different readings than my more expensive AirThings View Plus. Checked the EcoBee support website[1] and it made a lot more sense.
“Based on the VOC measurement, it can also estimate carbon dioxide (CO2) levels. The sensor doesn’t directly measure CO2 but assesses CO2 levels based on the average correlation between VOCs and CO2 in exhaled human breath.”
