Hi Wolferl

I notice that your data is stopped every day from 7pm to 1 am .
It is not clear whether this is internet connection or the power to the Kit1
This switching is not typical of the A3 unit and could cause different readings especially if the KIT1 lost power periodically.
I also noticed that your CO2 module reads very low with values much lower than CO2 sensors installed indoors in the recent run of A3.
There are however random excursions of your CO2 values on Oct 5 and 7th…
In both our cases it appears that the CO2 sensor behaviour is a mystery.
