THSW-Index, Cloudheight and Average values

[Sperber]

In my old meteohub with Davi Vpro2 i find the values for THSW-Index "akthumidex", Cloudheight and Average values for Temperatur ect.
Dont find this for the pro Version.

Are there any more values now?

The admin has holiday ?

humidex is not supported. Too few make use of it and also storing it will eat precious RAM and flash.
When you don't need to have it persistent, but just actual values, I could implement it with
one of the next releases.

Thanks for info...
please please release it
I like it on hot Days...
My old box has support this and my new pro has no support for this...
actual values, max and min,..I had before

p.s.: [mbsystem-cloudheight] is not going too

thx

I vote for this request. THSW seems to have a general consensus over the climate specialists. Thank you

Cloud base is something you can easily calculate, using MB parameters, see https://en.wikipedia.org/wiki/Cloud_base
it's the difference between outside temperature - dewpoint in degree C, divided by 2.5 . This gives cloud base in thousands of feet.

THSW is a bit more complex. How Davis is calculating this, is introduced in their "AN_28-derived-weather-variables" manual, see https://www.davisinstruments.com/produc ... iables.pdf .
It uses the Steadman formula with following parameters: Temperature, Humidity, Solar Radiation, Wind Speed, Latitude & Longitude, Time and Date.
The Davis document is not displaying the actual formula's. But try to google "Steadman apparent temperature formula" and you 'll get the original work from 1979 and later modifications. And lot of discussions.
It's very complex matter and likely taking too much computing resources from the MB. It can better be calculated using the options of your website.

There is no need to try to recompute something that the VP2 does very well. All we are asking is to have the value exposed by Meteobridge. Is it possible?

[admin]

Meteobridge is not a one-station SW. Therefore, I am not looking at perfection to mimic every single special feature of every station which can be connected.

Sure, but NANO HD is definitely dedicated to Davis VP2 and this index is really very interesting. So it is just to bad that it can't be reported.

AFAIK that value is not available. It is only calculated and visible in the console.

Would be interesting how Weatherlink handles it

When I look at your posting history it is constant listing of things you would like to have additionally. I think you have a lot here, work with it.
