OK, It's up and in, and seems to be working as it should.
Had a few glitches, seem to have them worked out.
I'll know for sure after sunrise tomorrow when I can confirm things.
They don't give good, or even any explanations for a lot of the stumbling blocks I found during setup.
But, I seem to have gotten them figured out.
My install looks to be very much in tune with other nearby installations.
Not much difference in readings.
I made one change.
Instead of mounting it on the house's metal roof, I mounted it on the spa's pergola roof on a 6' pole.
It's further away from the display, but still has a somewhat better distance to some obstructions.
Thought I had, but guess I hadn't mentioned that I lived on the windward side of Big Island.
That puts my home on a clearing in the jungle.
Many nearby tall trees.
It seems that the things affected most were wind speed and direction, but not badly enough to make them useless.
Speed is still well indicated for potential house harm when hurricanes or other wind storms come through.
Wind direction is variable, but still grouped in trains approximating its primary direction of travel.
Everything else looks to be pretty good.
The solar radiation monitor will be useful in monitoring what's happening with our PV and solar hot water systems.
I live in a high rainfall area and can now have a good handle on the precipitation we actually get.
I think it'll be a much better indicator than NWS based 50+ miles away with their shotgun calculated forecasts.
