MultiChannel gas sensor problem

Trying to get values from my new MultiChannel gas sensor. Even after calibration I get "invalid values". Printing eg NH3 gives -1.
I tried with both an Arduino MKR 1200 + Arduino Grove shield as well with an SODAQ SARA N211 (Grove connectors on-board).

Any idea what can be the cause?


When trying with the RawData sketch I get values.
The invalid values I get with the ReadSensorValue_Grove sketch. Am I right this sketch can't be used with the boards I use?
