Perhaps the weather feed it uses can work with SMX.
Sysmetrix uses METAR information for current weather conditions that is (was) retrieved from the NOAA website. Unfortunately NOAA recently deprecated the page METAR information was retrieved from, so that information is no longer available at the old URL used by Sysmetrix.
The Winstep Nexus dock uses multiple weather feeds (Weather.com, Yahoo, MSN, METAR and Google, until Google killed their feed) to minimize the possibility of a complete outage when one or more feeds go down or are changed by the providers (something that happens more frequently than we would like).
Because Nexus uses these feeds in a redundant way, when NOAA broke the METAR feed nobody other than me noticed because current weather conditions started being automatically retrieved from the other feeds. This gave me all the time I needed to get METAR working again on the next release, by changing the code so it used another source for METAR information.
The code changes are actually quite simple since the format of the METAR weather string itself remains the same. In fact, it's a lot easier to get that information now: while before you needed to first parse an HTML page to extract the METAR string, METAR information is now available directly from text files (e.g.; LPPT.txt) whose contents are automatically updated by NOAA. The code changes required to retrieve this information are thus pretty much trivial.
So, perhaps one of you guys should fire up an email to Nick. If he is willing to update Sysmetrix, just tell him to get in touch with me, I'll be happy to share what I know with him - we used to talk a lot in the old times.
