Alan: I like it on your site.

Mark: WeatherCat tracks total sunshine hours so I know it's in the database somewhere.

Mark,

we are able to indicate sun shining now in SteelGauges, so the data for taht must be somewhere, or it is computed by the script somehow:

Code: [Select]

showSunshineLed    : true,                   //Show 'sun shining now' LED on solar gauge

Reinhard, I believe the LED to display sun shining now on the SteelSereies Gauges is a calculation done by the Gauges software. There are two lines in the gauges.js where you can experiment with the parameters so you can tweak that LED to be more accurate depending on your specific location. But I assume that some kind of similar calculation exists in WeatherCat in order for the 'Cat to calculate total sunshine hours.

The script does do the calculation as not all the weather programs provide the "IsShining" data, so as the calculation is simple I do it on the fly.

[Blicj11]

The WeatherCat data should be more accurate as it is based on readings from the Solar Radiation sensor.

[mcrossley]

Well, the script uses the data supplied by WC too The key is the percentage threshold, and any absolute cutoff value (the WMO uses 120 W/m2 as the minimum threshold required for sunshine - I think to maintain consistency in readings with the Campbell-Stokes recorders which need a minimum level to burn the card)

I have my threshold set much lower because the light wasn't turning on when it should have been in the late afternoon, so I just stared playing around until I got it to where I felt it was reasonable accurate compared to what I saw looking out the window.

HERETIC! BLASPHEMER!! I hope the Admins here take note of your lower moral behavior!
