I dug a 2' 8" hole in my yard using a pole digger, mounted my Davis Vantage Pro2 on my 8' fence post and began recording real outdoor weather observations. I also created a Wunderground station, KMANATIC3, and set up weewx to post weather information to Wunderground every 5 minutes. If you are following along at home, one thing I should note is that I got an INVALIDPASSWORDID error from Wunderground up to about 10 minutes after I created the station at Wunderground.com. But, then it went through fine without me having to do anything.
I must say, it's been a pleasure to use weewx. Hard to believe it's such a well-made product in it's first release!
