SO I am trying to graph my solar and UV in Weather display. Solar works fine but I can not get UV to graph. I am not sure where the UV gets it’s info. Looking at the graph tab there is a checkbox at extra sensor 4. It shows nothing. I assume I need to select a sensor number but I can not find which one I need to select.
AFAIK you just go Control Panel > Graph Setup > Solar/UV/Misc. Setup and check “Plot UV (stored as extra hum 4)” and choose the Max scale. You don’t have to enter any sensor number.
Note that graphing UV means that the Windchill label isn’t shown. . .
So I have beat myself to death still no joy something is mis-configured for sure. I not only do not get any graph info but I get weird results in many reports.
Here is some info from both my weather display web page but also from testtags.php. Maybe this will give someone some idea.:

Thanks for the Help

I forgot to mention I can see data on my console and I actually loaded Weather link on another PC and hooked it to my console. The PC I run Weather-Display on gets it’s data from a Davis Weather Envoy.
Thanks Leslie Earl

I’m sorry, but I know nothing about Davis/Envoy/Weather Link, just a bit about WD.
If no-one else chips in you may have to e-mail the author direct.
