1-wire Humidity as main and Dew Point readings

Due to inaccurate readings from my Vantage Vue Humidity sensor i have switched to a 1-wire Humidity as main in WD. I’m wondering does WD use the main humidity sensor when calculating Dew Point readings or does it come directly from the Vue???

WD uses the humidity reading
and so it will use that 1 wire humidity reading if you have set to use that, to calculate the dew point
