Incomprehensible.

Can anyone tell me what this function is?
I do not know who beats at all. :roll:


what exactly are you wanting to know?

What is the graph and the wheel on the left?

its not a wheel
its a gauge
that is colour graduated
of the current PM 2.5

the graph shows the air quality history data over the time period you have choosen

why so negative?

Maybe this explanation of AQI will help?

correction, the gauge is the AQI value (air quality index)

Yes thanks for the information, but if it shows the gauge and graph of some value on what basis does it work?
I have no sensor for measuring air quality, so how can there be some values?

Perfect timing, it’s actually cranky co-worker day at least in NA. :slight_smile:

I don’t, either, but mine works just fine - http://tiggrweather.net/wxaqi.php. Data is pulled from one of a few sites that maintain this info.

This is exactly what you need to buy for the right measurement. :slight_smile:

I’m confused. Why should I buy that when I get the accurate data I need for free?

I would like to get a round gauge on the WD main panel but it is not possible.
Is there any relative possibility of viewing it?

round gauge of what?

I can not get the AQI gauge on the taskbar.

what do you mean by task bar exactly?
windows task bar, or?

No, I mean the WD main panel.
I can only get a graph but not a gauge.

not sure what you mean by WD main panel either?

The AQI gauge can not get to the main panel wd.

you can set to have a web image file updated and then you could set that to be on the main screen via the main screen customisation as a custom image
