I replaced the temp/humidity sensor. There are now live temp/dewpoint readings showing up on the webcam page.
The wind dial is being a bit of a pain due to the bad data from the Dark Period(tm). I'll reset it in the next couple of days. Most of the changes I can do remotely but there's one double secret step that may require a trip to the Fort. As a result, I'll only take that step when I am free to make an emergency house call on site.
If any of you are interested, we use WView
http://www.wviewweather.com/ to run the weather station. It's open source and can use a few modifications for our purposes, so if you're game and are a C/*nix person let me know.
