Check the Weather-Display settings.. maybe you are uploading an old ./cache/uv-forecast.php from 2023.
I note that the get-UV-forecast-inc.php script always has both headers and contents of the fetch from the temis.nl site.

The 2023 version only has contents (no headers) so it is not coming from the script -- its coming from another source (maybe Weather-Display download and upload file?).

Yes, @Ivano I have the PT1000 sensors correctly set and calibrated. We checked with Pt100 class A them and the differences are not more than 0.03 deg.C in negative temperatures.

In general, the Barani shield gives a good performance when it is windy. When the wind dies down, it makes a sneeze like on any passive shield. Interestingly, even the Davis FARS24H has problems despite forced ventilation. It seemed that the "tube" would solve this, but the insulation is at a worse level than in the TS-100. It is also a different class of products.

I will probably dabble a bit bit if it gets too messy,  I will not bother.

It would be nice to fill the gaps but no real need.

And thanks again for all you help.
