Anyone else have an outdoor weather station from IQAir/AirVisual? I've been noticing the publicaly reported data from mine is wildly different from the internally reported data (and the internally reported data matches reality). Often it showing >20F lower than reality.

I tried submitting a support ticket and got no response. But like - the actual data is right but the public data is crazy off. Here’s a few recent screenshots to show what I mean.

Top is my outdoor monitor (internal data). Bottom is same time public data. (Middle is my indoor sensor if your curious)

Now it’s not only way off base - but predicting substantial rain 🤣 There is exactly zero chance of rain in the foreseeable future for this region.

fairly clear they are making some sort of adjustment to the data before making it public - but that adjustment is wildly off base.

Could they be averaging it over time while it's locally reporting instantaneous values?

I don’t think so. Much too far off for that. I’ve noticed that for my general area all of the public ones are reading too low - they list 6 inputs for the area, but you can only see 3, the other 3 are apparently purple air stations.
