You can calibrate the Neostat within the options menu to read the same. I used a reference calibrated thermometer to set mine up. 

I know. I said a few posts ago I’ve calibrated them. One of the first things I did was calibrate the various sensors so they all measured much the same. I bought the Ruuvi  for its humidity sensor as it comes calibrated and you can calibrate it yourself.
