NCIR unit weird values

  • Hi guys!
    So I got a m5stack with a ncir unit. I am using uiflow to test and I am getting temperature values all over the place... I was supposed to get 4ºC+- on my fridge and it says is -10ºC !! Other measures are also not consistent....
    Is there any way to reset the ncir unit or something like that? Or is it possible that it is faulty? Do your units give consistent results?
    Thank you!
