TVOC/Co2 Uiflow Problem

[aek56]

Hi there

The newly introduced Uiflow for TVOC does not work properly, it does not give me any CO2 and TVOC back, does all the time reports 400/0. Works without any problem in Arduino.

Can you please have a look at ? Would be a benefit for me to use it thru Uiflow.

Thanks and Regards

Same here.

I tried this and this keep displyaing eCO2 400...
Any idea?
