Unfortunately my Jinping's temperature sensor does not agree with sensors of 3-4 different makes I have it always reads 3-4 degrees C below the others.

Yep same here. Temperature seems weird. It has offset option but didn't work correctly for me. CO2 and PM seem ok, but I don't have anything to calibrate with except outdoors.

I do have CO2 monitors and they agree.

PM I have something that shows air quality and it shows 0 and high at the same time as the Qingping
