Hello 'Monstaa1',
no, the TFA AirCO2ntrol Mini does not have a data logger function.
The device 31.5000 (Galaxus item no. 5822967) has a data logger function and can store the data records for CO2 and temperature of up to 48 memory records of the last 24h (interval 30 min).
With kind regards
Your TFA Support

Manufacturer is
RADIANT INNOVATION INC. (ZyAura)
1F, No.3, Industrial E. 9th Rd., Science-Based Industrial Park, HsinChu, Taiwan 300, R.O.C

For data recording, TFA AirCO2ntrol Mini (ZyAura ZGm053U) is connected to the PC via USB.
The Datalogger Windows 7-11 software continuously logs to an Excel-compatible CSV file, is free of charge and can be downloaded from the manufacturer:

I have found the following information:

You can log the data with software from the manufacturer.

There are also 2 buttons (Mode / Enter) on the circuit board. These are available through holes on the rear wall (unfortunately not drilled). With these you can adjust the 2 threshold values in the range of 500..3000 ppm CO2 and thus change the functioning of the traffic light.
Furthermore, it seems to be necessary to enter the height of the sensor above sea level.
