New web tags <#THWindex> and <#THSWindex>

[BCJKiwi]

I was trying to find this info in the Vue an Pro manuals but finally found it in;
Davis Document 07395-281_IM_06316.pdf which is described as the "Vantage Pro2 Weather Envoy Manual For Vantage Pro2, Vantage Pro2 Plus and Vantage Vue Weather Stations".

Apparent Temperatures
The Weather Envoy calculates four apparent temperature readings: wind
chill, heat index, the temperature/humidity/wind index (THW Index), and
the temperature/humidity/solar radiation/wind index (THSW Index).

and

THW (Temperature - Humidity - Wind)
The THW Index uses humidity and temperature to calculate an apparent
temperature like Heat Index, but includes the cooling and heating effects
of wind on our perception of temperature.
THSW (Temperature - Humidity - Solar - Wind)
The THSW Index uses humidity and temperature like for the Heat Index,
but also includes the heating effects of sunshine and the cooling effects of
wind (like wind chill) to calculate an apparent temperature of what it
“feels” like out in the sun. The THSW Index requires a solar radiation
sensor.

THSW is mentioned in the Vantage Pro2 Manual but not anywhere else that I can recall.

Below is a quote from the WeatherLink help files of WL v 6.0.3, which I believe is the current version. It appears that if you are running WL earlier versions you can't get a THWS reading from the station for incorporation in reporting software.

"WeatherLink versions 5.3 and later support a new derived data parameter, the Temperature Humidity Sun Wind (THWS) Index. If your station has a solar radiation sensor, this value can be calculated for existing data.
Choose Recalculate THSW Index to get the THSW index for data collected prior to installing WeatherLink 5.5.1. Be sure to verify that the latitude and longitude settings and daylight savings time settings are correct before using this command.
Note: If you don’t use Daylight Savings Time or if you set Daylight Savings manually in WeatherLink, you will be prompted to enter the Daylight Savings Time dates before WeatherLink exports the data. Either enter the dates and times you manually changed your station to Daylight Savings, or just click OK if you are not using Daylight Savings Time."

WeatherLink "Bulletin" & "Summary" do not show the THWS index, but it is shown in "Database" if you select it & one of the columns has the THWS index. One would assume that if the console & WL show it then the DLL must be passing it through, of course assumptions are not always correct.

The DLL provides THW and THSW, Cumulus reads both of them, and makes them available as web tags.

The THW Index works fine, I display it on my web site. The problem, as described earlier in this thread, is that the THSW reading doesn't work. Presumably this is why Davis have added it to the newer LOOP2 packet.
