[Edited to change “Air” to “Sky” throughout the post – OOPS!]
I have my Sky (original post mistakenly said “Air” and also elsewhere) (not Tempest) unit mounted at the end of our house about 8 feet above the peak of the roof. Our neighbors are having their roof done this morning, with lots of hammering, including air-powered nail guns and regular hammers.
When they were working on the section of roof right across the property line from where my Sky is, I got a false “It is raining” report on my Sky!
I don’t see this as a bug (after all, how often is it going to happen) but a humorous curiosity.
