Hello, I would appreciate some help.
Yesterday was very windy due to ex Hurricane Ophelia that affected Britain. We had a couple of brief power outages and immediately following the second outage I noticed the console was showing wind speeds over 100mph! The highest gust of the day prior to this was a mere 57mph (but still one of the highest readings here) and so it was obviously erroneous. I reckon the wind was still managing gusts of 45 - 50mph at this stage. I rebooted the computer and then the wind readings returned to normal for a while, however the problem has recurred intermittently since. First thing this morning it was again showing over 100mph when in fact the wind was light (below 10mph) but it has been ok since then. The Davis anemometer is up on the roof and appears ok from the outside as do the cables. Any ideas? Many thanks, Tony, Wales, UK.
