I currently have two VP2's mounted at the same height AGL and within two feet of each other. The first is a VP2 that has been upgraded to the SHT31. The second is a VP2 with the original SHT11 but also fitted with DFARS. Below are a couple of graphs showing the two units over a period of 22.5 hours, midnight to 10:30pm one spring day in Virginia. More specifically, April 15th, 2017. The first chart shows the readings from each station. The second chart shows the delta in higher resolution over the same time period.
I should add that the delta chart is shown in degrees Fahrenheit as I am an American and cannot think in Celsius.
I make no conclusions from these charts, I'm just sharing them for others who share my curiosity.
