Wet Bulb (WBGT) in 2026

[David Hathaway]

As the FIFA World Cup (tm) ramps up, we here in Houston are getting a load of notices about how there is a mandatory water break in matches, even though it is played indoors. :-/ As I discussed this with my friend the sports trainer, he mentioned that Texas now has a rule that they must do certain things according to the WBGT.

I have searched here for wet bulb additions to WeeWx.  I see discussions from 2024 and wonder if there is someone with a more recent idea about implementing this.  Does anyone calculate the Risk Level and provide Guidance?

I am trying out an agentic Ai to read the RSS XML feed; It loves this format.  I've not messed with the RSS export.  Is there some intrisic gotcha?  I really only care about current values.

Quick search seems to say a WeatherFlow Tempest station has this, but I can't find it mentioned in any of their API so I don't see a way to get it into weewx for this one model station - https://community.tempest.earth/t/wet-bulb-globe-temperature/14386/11

Other threads and docs with the formula seem to say you need special sensors for this, so I can't speculate how WeatherFlow fakes something to generate that item.

There is a 'wetbulp.py' (note the p) in this group that calculates it as a xtype_service.  This conversation,
