I think there is no CO2 sensor installed in the Itho.
Only the Temp en Hum sensor is available. Did you install an extra add-on in the Itho for Co2?

65

no I have not added an add-on, but via the ip address of the wifi addon I do see a co2 (ppmw) see photo previous post.
The remote also has an auto function that I think extracts on co2, I thought…

I know what you mean because I use the same module for my Itho.
If you have a Temp/Hum sensor installed on the module then there is no space to add an CO2 sensor.

The developer is working on a new sensor that includes CO2 but I think that will take some more time.
In the mean time I have a separate Air Quality meter installed.
