As stated before, variablilty is the norm with the SHT31. Currently (8pm):
New station (24 hour fan)—T 71, H 84
2 year old station (daytime fan)—T 72, H 79
2.5 year old station (daytime fan)—T 72, H 82.
Again, all on the same fence, same height, at most 50 feet apart.
Temperature is right on, humidity, well pick a number. That said, they are “directionally” the same. But many users are correct, the humidity reading is low in importance to most folks.
The good news today, we had a rain. All three VP2 stations reported .50 give or take which matched my CoCo gauge! It has been many moons since that happened!
