I have one, but we only use it to rotate our wood if we feel we had to since we can bring it back a bit haphazardly when there is windfall or storms, or when we are going to sell it just to make sure. But by now I can simply tell looking at it and hefting it whether it is seasoned or not.
I don't think the ambient humidity here ever dips below 25 or so. Unless we have a particularly hot and dry summer, it usually takes 2 years to season most woods. UK and Ireland are islands. We're fed directly by the gulf flow. So we rarely have a hard freeze outside of the north even though we're at nearly the same latitude as northern Canada, eh. But it does help to keep our skin nice and moisturized. We also get plenty of random from the med. So it is rarely truly dry here. I do recall one summer, maybe 2013, where I actually saw dust here and was a bit surprised.
Where we are, in the Suir valley, the wind can get bad during the winter storms. So all our barns that perpendicular to the river have slats on the windy side. This allows a bit of rain in, but the wind does a pretty good job drying wood out most the time.
The breezeway lean-to. Back of it faces the storm winds. It does OK drying the wood, tho. Even so, you'll notice it doesn't look particularly dry.
Much of what ya see above is from this dude:
